"Вуазен" 1909 г. - один из первых самолетов в Западной Европе, летавший еще в 1908 г. В Россию он попал летом 1909 г. По схеме это был трехстоечный биплан с передним рулем высоты, бипланным хвостовым оперением и толкающей силовой установкой с довольно несовершенным воздушным винтом. Характерны вертикальные переборки по концам коробки крыльев и гондола перед крылом, напоминающая по форме утиный нос. Элеронов и гоширования еще не было. На таком самолете были совершены первые в России в XX веке полеты русских авиаторов в Одессе (начиная с 12 июля 1909 г.) и французского авиатора Леганье осенью 1909 г. в Гатчине и в Москве. Летал самолет плохо, не всегда удавался даже взлет. С 1910 г. он уже не применялся.

The Voisin Machine. Origin and Description.

  MM. Voisin began their experimental work some years before their name was known to the general public, or rather some years before their machines came into public prominence through the exploits of Farman and Delagrange, for comparatively few people, even at the present time, are even aware of the name of the makers of these most successful machines. In 1904, MM. Voisin constructed for M. Archdeacon some cellular kites of a large size, of very much the form of their present type of machine ; these were tested in tow of a motor launch on the Seine, and provided much of the data that MM. Voisin afterwards utilised in the construction of the actual flying machines that brought their work into public prominence.
  MM. Voisin (and their engineer or works manager M. Colliex, who is largely responsible for their designs) make no secret of the fact that they have based their work on that of pioneers such as Lilienthal, Langley, and others, and in fact they say that they never miss an opportunity of utilising any information or data on which they can lay hands. On the other hand, much of their work is based on their own researches; they appear to take little for granted, having equipped themselves with an "artificial wind" apparatus, with which they test their work on a small scale before finally settling a design.
  The Voisin factory is on a comparatively small scale; the output and work in hand at date includes (amongst others) some five machines of the Farman-Delagrange type, and four machines of a modified pattern, with an aerofoil consisting of three superposed members. The former is the only type of machine for which flight data are to hand, and in the remarks that follow it is this type to which reference is made as the Voisin machine.
  It appears from statements made to the author by MM. Voisin (and confirmed by Mr. Farman himself) that when their designs were prepared, the first order they obtained was from M. Delagrange and the second from Mr. Farman, who placed his order for what was practically a duplicate machine. That Farman made successful flights before Delagrange was due in the main to the fact that he had made in advance appropriate arrangements for testing and trials on the Champ de Manceavres at Issy-les-Moulineaux, a precaution that the latter neglected, and it would seem that it is hopeless to attempt to fly, at least with a new machine, without some such provision. It also appears that the Delagrange machine went through some kind of a history in its early state, the wheels fitted in the first instance not being arranged as it was subsequently found necessary to arrange them, namely, as castors, or as the French express it, " orientable." It is this provision that takes care of any slight side component of the wind when starting and alighting which might otherwise upset the machine.
  The Voisin machine is given as weighing complete, with Mr. Farman " up, " 1,540 lbs. (700 kilogs.), and has a total supporting surface of 535 sq. ft., this being the combined area of the horizontal members of the aerofoil and the tail, both being used for sustentation, though there are reasons for supposing that the pressure per sq. ft. on the aerofoil is greater than on that of the tail.
  The ordinary maximum velocity of flight is approximately 45 miles per hour, or 66 ft. per sec. ('=72 kiloms. per hour).
  In addition to the horizontal sustaining members of the aerofoil and tail there are a number of venical members whose function is to preserve and control the direction of flight, and to give lateral stability; these have a total area of approximately 255 sq. ft.
  The supporting surfaces of both aerofoil and tail are of rectangular plan form, the former being 10 metres by 2 metres, and, therefore, having an aspect ratio - 5. The aspect ratio of the tail members is 1 '25; they are, therefore, nearly square.
  The Voisin machine is propelled by a single screw of 7 ft. 6 in. diameter (2-3 metres), of which the effective pitch is approximately 3 ft. (the actual pitch is much greater, the "slip" being excessive). The propeller is keyed direct to the motor shaft.
  The motor fitted to the Voisin (Farman) machine is an 8-cyl. "Antoinette," 4-35 ins. diameter by 4-15 ins. stroke ( 110 mm. by 105 mm.), stated to give 49 b.h.p. at 1,100 revs, per min. ; its weight is given as 265 lbs. (120 kilos.).
  It is said that the gliding angle of the Voisin machine was at first approximately 1 : 5 or 11 degrees, but that by detail improvements in diminishing framework resistance by rounding off and covering in to form stream-line sections, the gliding angle has been improved, and is now about '16 radian, that is between 1 : 6 and 1 : 7, or 9 degs. approximately.

"Delagrange No. 3."

Biplane constructed by Voisin Freres, and exhibited by the Soc. d'Encouragement d'Aviation in order to advertise their new Juvisy Aerodrome, which opens on January 10th. The general lines of the machine are well known to readers of The Automotor Journal. It has in addition to the two main planes an elevator in front and a rudder enclosed by a box-kite tail behind. The pilot sits in the centre between the main planes, and is thus just in front of the engine # a 50-h.p. 8-cyl. Antoinette # which drives a 2-bladed propeller mounted on the end of its crank-shaft. There are two side curtains between the main planes, one near each end.

"Voisin-Farman No. 1"

  Biplane constructed by Voisin Freres on the lines of "Farman No. 1," and equipped with a dummy pilot to give reality to its setting over the grand staircase, where it looks for all the world as if about to fly off from the balusters. The general lines of this machine are the same as the " Delagrange," and it presents the same workmanlike appearance which is characterising the Voisin productions. It is neither clumsily heavy nor flimsily light, but appears to have just a reasonable degree of rigidity which does the builders credit for their judgment in design.

Moore-Brabazon and His Engines.

  MR. MOORE-BRABAZON is trying another engine on one of the Voisin aeroplanes, and this time it is an E.N.V. 8-cyl. motor which he has selected.

Moore-Brabazon Flies Easily.

  WITH the new engine Moore-Brabazon has got along much more smoothly in his flying. On Wednesday, at Issy, in the early morning, he repeatedly made circular kilometre flights without the smallest sign of effort, his machine behaving splendidly. So much so, that he already sees himself on the way for a long flight. His biplane is to be transferred to Chalons, where a special hangar is now being erected, and he then intends to try for some more ambitious records, bringing him a little nearer to the top than the fifth place at present reached by him.

"The Bird of Passage" (J. T. C. MOORE-BRABAZON).

  Such is the name which Mr. J. T. C. Moore Brabazon has given to his No. 4 flyer which, like its predecessors, was constructed by Voisin Freres in France. It is the actual machine with which Mr. Moore-Brabazon made his latest famous flights at Issy, and it is the only flyer in the Show that has actually flown incidentally, the mud on the wheels and chassis give the fact an air of practical reality. This particular flyer which is, of course, typical of the Voisin construction and to which our remarks about the Voisin machine exhibited by Mr. F. R. Simms therefore apply, happens to have been the first of the new pattern in which the distance between the main decks was increased from 1.5 metres to 2 metres. "The Bird of Passage" is equipped with an E.N.V. 8-cylinder engine which drives a twin-bladed propeller direct. The pilot sits in front of the engine in a rectangular car which projects forward to carry the elevator. Directly in front of him is a steering wheel like that on a motor car, but set on a horizontal spindle; this wheel the pilot turns to steer and pushes bodily to and fro in order to ascend and descend.

Voisin (F. R. SIMMS).

  The biplane exhibited by Mr. F. R. Simms, who has secured the sole concession for these machines in this country, is one of the standard Voisin machines and affords an excellent example of the Voisin system of construction. Next to the Wrights', the Voisin flyers have been the most successful which have yet taken their place in the air. The great feature of the Voisin system is, as our readers know, the use of a box-kite tail, carried by an outrigger framework some distance behind the main plane. This tail, which encloses the rudder, is itself employed for the purpose of giving automatic longitudinal stability, the idea being that the wind blowing on to the tail uses the leverage afforded by the outrigger framework to bring the machine once more on to an even keel. In front of the main planes is an elevator, and between the main planes there are fixed four vertical side curtains; the car which carries the engine and the pilot is also covered with fabric.
  The Voisin machine is certainly a well-built job, and it has a number of constructional details of considerable interest, some of which may or may not, of course, stand the test of time. The main planes are single surfaced, and the decks are thus very thin and flexible, which causes the spars and libs to stand out rather prominently; each member is, however, encased in its own special bag.
  It is a feature of the Voisin design, possibly resulting from certain details of construction, that each main plane as an overhung flexible rear edge which can adjust itself to the air streams. The elevator in front, on the contrary, is rigid fore and aft, and has top and bottom surfaces, which are nearly two inches apart at the thickest point. All the struts of the Voisin machine are elliptical in section, and have sharp cutting and trailing edges; they are neatly and rigidly mounted in aluminium sockets, which are bolted to the main spars. All the tension wires are adjustable. The machine is mounted on a two-wheeled chassis in front, and has a pair of small wheels under the tail; the suspension of the former is effected by long helical springs.

Delagrange (MASS CARS).

  The Delagrange biplane as exhibited by the Mass Co. is a slightly modified Voisin machine; the modification consisting in the abolition of the four vertical side curtains which the Voisin machines proper employ between the two outer pairs of struts separating the main planes. In the machine shown, too, the distance between the main planes is 0.5 metre less than that on the modern Voisin machines. The control is unaltered and the details of construction are likewise unchanged; the engine with which the flyer is equipped is a 50-h.p. 8-cyl. Antoinette.
  M. Delagrange has, as readers of FLIGHT know, met with a considerable measure of success with these machines. He was one of the early winners of the Aero Club of France 200 metres prize, and for a brief period before Wright's achievements in that country, actually held the world's record with a flight lasting nearly 30 minutes, during the course of which he accomplished a distance of 247 kiloms., by making 15 1/2 circuits of the Issy Parade Ground. Among other places, he has flown in Rome, and among other notable facts in connection with his performances is that he took aloft the first lady passenger, Madame Therese Peltier.

Aeroplanes to be Blessed.

IT has been no very uncommon thing to record in the past the blessing of motor cars by the Roman Church in France. Apparently the same procedure in some quarters is to be followed in regard to flying machines, as a formal gathering this week took place on April ist at the invitation of the Compagnie d'Aviation at Juvisy, when benediction was pronounced by the Archbishop of Paris and the Bishop of Versailles over the aerodrome of the above-named company, and incidentally over the flyers which happened to be there at the time. We await with curiosity the name of the special Saint under whose protection aeroplanes have been placed.

Blessing Aerodromes and Aeroplanes.

LAST week we referred to the innovation of blessing the new aerodrome at Juvisy and the two Delagrange aeroplanes there. We now give in our frontispiece a couple of photographs illustrating this curious ceremony. It will be sean that a sort of grand stand was erected for the occasion, and to the front of this the two aeroplanes were brought. The service was commenced by Mgr. Amette, the Archbishop of Paris, delivering an address, in the course of which he said that man by his original fall lost the sovereignty of the air, but the present inventions permit it to be hoped that man may be allowed by Divine grace to regain some small fragment of his original sovereignty. The Church was therefore happy to bless the machines, destined to soar through space and conquer realms hitherto beyond man's domination.
Short prayers were then uttered that those using the aeroplanes might be preserved from accident, after which one of the aeroplanes was named "Ile de France," by Baroness Lagatinerie, and the other "Alsace," by Madame Dussand, and sprinkling them with holy water, the Archbishop blessed them. At this moment a change came over the heavens, and, as if in sympathy with the Archbishop's movements, rain fell in torrents, causing the "godmothers" and the assistants to flee for shelter. About five hundred people witnessed the ceremony, including the Duke and Duchess of Rohan, Princess Murat, Prince and Princess Leon, Marquis and Marchioness of Castellane, Marquis and Marchioness of Puybaudet, &c.

The Farman Aeroplane (Fig. 24).

The Farman flying machine has two superposed aero-surfaces 4 ft. 11 ins. apart, with a spread of 42 ft. 9 ins. and 6 ft. 7 ins. from front to rear. The total sustaining surface is about 560 sq. ft.
A box tail 6 ft. 7 ins. wide and 9 ft. 10 ins. long in rear of the main surfaces is used to balance the machine. The vertical sides of the tail are pivoted along the front edges, and serve as a vertical rudder for steering in a horizontal plane. There are two parallel, vertical partitions near the middle of the main supporting surfaces, and one vertical partition in the middle of the box tail. A horizontal rudder in front of the machine is used to elevate or depress it in flight.
The motor is an 8-cyl. Antoinette of 50-h.p. weighing 176 lbs., and developing about 31-h.p. at 1,050 r.p.m.
The propeller is a built-up steel frame covered with aluminium sheeting, 7 1/2 ft. in diameter, with a pitch of 4 ft. 7 ins. It is mounted directly on the motor-shaft immediately in rear of the middle of the main surfaces.
The framework is of wood, covered with canvas. A chassis steel tubing carries two pneumatic-tyred bicycle wheels. Two smaller wheels are placed under the tail. The total weight of the machine is 1,166 lbs. The main surfaces support a little over two pounds per square foot. The machine has shown a speed of about 28 miles per hour, and no starting apparatus is used.
On January 13th, 1908, Farman won the Grand Prix of the Aero Club of France in a flight of 1 min. 28 secs., in which he covered more than a kilometre. It is reported that on October 30th, 1908, a flight of 20 miles, from Mourmelon to Rheims, was made with this machine.

Opening of the Juvisy Aerodrome.

  THE opening of Port Aviation - the aerodrome at Juvisy - on Sunday last was somewhat in the nature of a fiasco. Great preparations had been made, and it had been extensively advertised that there would be an exciting aeroplane race between Delagrange, Rougier, Bleriot, and others. A large crowd of spectators, estimated by some people as something up to 100,000 - probably 10,000 is nearer the mark - assembled and patiently waited for some hours to see the flyers in the air. The kite-flying competition which was on the programme for the afternoon did not secure a great deal of interest, and as there was no signs of the aeroplanes being put through their paces, murmurs of discontent began to arise. At last M. Delagrange made several short flights, but that did not satisfy the crowd. Eventually, about five o'clock, it looked as though some damage would be done, as the crowd began to encroach on the course and threatened to invade the pay-offices and smash the grand-stands, &c, up. With characteristic pluck, M. Delagrange came to the rescue. Although he was hampered by the people swarming on the course, he started off and covered five circuits of the course. Rougier also made an attempt to fly, but he was so unnerved by the people crowding upon him that he was unable to complete one circuit. The judges therefore decided that M. Delagrange was the winner of the Lagatinerie Prize, but as only two machines competed, the value of it, in accordance with the rules, was reduced to 2,500 francs. The official record of M. Delagrange's flight states that he covered five circuits, a distance of 5.8 kiloms., in 10 mins. 18 3/5 secs.
  The next event at Port Aviation is to be held to-morrow (Sunday), and will take the form of a high jump contest, a line of balloons being fixed at a height of 25 metres, and the competitors having to "jump" over them.

M. Paulhan Flies.

  "SLOW but sure" is the motto of M. Paulhan, who has been practising on his Voisin biplane at Issy, and for some days last week he contented himself by making several "jumps" in order to familiarise himself with the handling of the machine. On Saturday, after several short flights of about 200 metres in length, he decided upon a more extended flight and made not quite five circuits of the grounds, amounting to about eight kiloms., the altitude not being very great, varying between two and five metres. He then gave notice to the Aero Club that he would make an attempt on Monday to win one of the 500-metre prizes, but unfortunately some trouble was experienced with the motor, and although the machine made several short jumps, it did not keep going sufficiently long to cover the course. M. Paulhan is, however, very well pleased with his progress, and is now at Douai, where he intends to take part in some of the competitions there.

Captain Ferber at Belfort.

  ON Sunday last, Captain Ferber made several flights on the Champ de Mars, on a Voisin biplane. The secret of the identity of Captain Ferber and the successful "De Rue" is now an open one. It will be remembered we referred some weeks ago to "De Rue" being the assumed name of a well-known aeronautical enthusiast.
  Captain Ferber also made six very successful flights on Tuesday of this week at Belfort, although they were all fairly short. Satisfied with the running of his machine, he thereupon had it sent off to Vichy for the meeting.

Flight, August 14, 1909.


  WHILE Farman and Delagrange were arousing the enthusiasm of France, and attracting the keen interest of all nations to their brave and diligent attempts to conquer the air, the designer and constructor of the first practical type of French flyer remained in comparative obscurity; for the moment everyone overlooked the man behind the machine. M. Voisin commenced his experiences in flight at a sufficiently early period in the modern history of the movement, for he made his first public effort as pilot of the glider with which M. Bleriot inaugurated aerial experiments over the Seine. Bleriot's glider was towed by a fast motor boat, and more than once M. Voisin found himself prematurely plunged thereby beneath the surface of the water. When Voisin and his brother settled themselves down to the designing of a motor-driven machine, they made no particular outcry about the occasion. It was not until after the successful flights which Farman and Delagrange had made with their device had been adequately applauded, that France herself began to realise who it was that produced them. For his work, however, M. Voisin has received the very just award of having his name included on the first list of decorations to be awarded in connection with the science and art of flight.
  One of the first of those to secure a Voisin flyer was Mr. Moore-Brabazon, and it is of this machine, now housed at Shellbeach, that the owner has very kindly permitted us to make the accompanying scale drawings for the benefit of readers of FLIGHT. Mr. Moore-Brabazon's "Bird of Passage," as he has named his flyer, is a machine with which he has achieved several flights. In fact, his early progress in the mastery of the air with it was remarkable. Since its arrival in this country he has also flown, but not to the same extent, partially owing to the inclemency of the present summer.

Leading Characteristics.

  The Voisin flyer is an original type of machine, and it is therefore the more important to specifically state its leading characteristics. Broadly speaking, the great point in the Voisin flyer is the fact that it has a tail, this member consisting of a kind of open-ended box carried at the rear upon a light outrigger framework extending some thirteen feet behind the main decks.
  Having two principal supporting surfaces, the Voisin flyer belongs to the biplane class, and in this respect is similar to the Wright machine, with which it has another point in common, in the presence of an elevator. The elevator consists of a pivoted plane mounted about six feet in front of the main decks. Apart from the presence of the tail, the greatest contrast between the Voisin and Wright types lies in the absence of any wing warping or other special method of maintaining lateral stability in the Voisin flyer, beyond what is available from the effects of steering by the rudder.
  Unlike the Wright flyer, which is supported upon runners or "ski," the Voisin machine, when on the ground, rests upon a wheeled chassis, and it is a leading characteristic in the construction of the machine that this chassis is attached to a kind of girder which supports the engine, contains the driver's seat, and carries an extension on which the elevator is mounted. This chassis-frame is one of the elements into which the machine can be dismantled for transport.
  The last, but by no means the least important, characteristic of the Voisin flyer is its use of a single high-speed propeller mounted direct on the crank-shaft of a 50-h.p. engine.

The Main Decks.

  The main decks have a total span from tip to tip of approximately 33 ft., and a fore and aft chord of 6 ft. 9 ins. They are single-surfaced with fabric which is stretched over a foundation consisting of ash ribs lying across two transverse main spars. Two spars are placed about 5 ft. apart, and the ribs, which end up flush with the front spar, overlap the rear member a matter of 21 ins., whereby the trailing edge of the decks becomes flexible to a limited extent. This flexible trailing edge is a feature of Voisin construction, as also is the single-surfacing of the decks.
  The "Continental" surface fabric is so attached that it lies beneath the ribs, but these members are enclosed in pockets of the same material; it is this feature of the construction which gives the uneven appearance to the upper surface of the deck. In order to avoid sharp angles, the main transverse spars are also covered by strips of fabric so fastened that they give the spars a virtual triangular section.
  All the ribs which lie between the two main spars are not alike, for at intervals coinciding with the vertical struts which separate the decks the ribs are considerably larger, and are built up to form an inverted T section. Before being mounted, the ribs are permanently set to the required shape, so that the decks when surfaced shall have the proper camber.

The Tail.

  The tail, which is also of biplane form, is constructed on exactly similar lines to the main decks, and although it has a smaller gap, and a much shorter span, the chord is the same dimension. The area of the two decks of the tail is nearly one-quarter of the area of the main decks, and it is necessary to bear its value in mind when considering the effective supporting area of the whole machine. The aspect ratio of the tail is only a little more than unity.

The Elevator.

  Unlike the tail, the elevator does not resemble the main decks, either in its form or construction, for in the first place it is of the monoplane type, secondly it is double-surfaced. The elevator is, owing to its method of mounting, divided into two equal portions on either side of the girder frame, which juts out in front of the main deck. The area of both parts combined is 45 sq. ft. or a little more than one-tenth of the area of the main decks. Its effective span is 13 ft. 10 ins., and as its chord is 3 ft. 3 ins. the aspect ratio of each portion is about 2.
  The ribs which stiffen the elevator are sufficiently thick at the maximum section to allow the hinge-rod to pass through them, and fore and aft of this point, which lies 10 1/4 ins. behind the leading edge, the ribs taper to a point. The hinge-member consists of a 1 1/4-in. steel tube, and the maximum depth of the elevator at this point is about 2 1/2 ins. Being double-surfaced, that is to say, having a fabric covering top and bottom, the ribs and the hinge are entirely enclosed. The elevator is virtually cambered by its arched upper surface; the bottom surface is approximately flat.
  The operation of the elevator is carried out by means of a connecting-rod attached to the steering-wheel spindle. This latter member is mounted so that it can slide in its bearings, and the pilot is thus able to set the elevator by pushing and pulling the steering-wheel bodily to and fro.

The Rudder.

  The rudder resembles the elevator in form and construction. It is situated between the decks and the tail, being mounted upon a vertical hinge pivoted upon the rear transverse spars of the tail decks. Owing to the tail itself having a flexible trailing edge most of the rudder lies wholly within the tail, only about 1 ft. 3 ins. of its chord projecting in the normal position. The hinge of the rudder is about 18 ft. 4. ins. behind the rear edges of the main decks.
  The operation of the rudder is effected by wires, which pass round a wooden drum on the steering spindle.

(To be concluded.)

Flight, August 21, 1909.

(Concluded from page 488.)


  ANOTHER feature which characterises the Voisin flyer is the presence of side-curtains between the main decks and also between the decks of the tail, these members being thereby converted into a kind of box-kite construction. Between the main decks there are four sidecurtains, one at each end and another between the vertical struts adjacent to those at each end. They consist of sheets of the same surface material as is employed for the decks, and are stiffened by fiat ribs enclosed in pockets. To a certain extent they may also receive support from the diagonal wireties which lie adjacent to them.
  The real utility of sidecurtains has been questioned by some aviators, and M. Delagrange has flown a Voisin machine without them. Leaving aside all considerations affecting those employed between the main decks, it appears to us that the possible influence on the effectiveness of the rudder, of those in the tail, ought certainly to be taken into consideration. We have already pointed out that the rudder is almost entirely enclosed within the tail, and it is difficult to believe that the side curtains do not effect its action.
  The part played by the side-curtains between the main decks is not altogether too well defined. They afford a considerable extent of cutwater, which doubtless assists the machine in turning, and it is possible that they also tend to minimise the direct effect of side gusts suddenly striking the machine obliquely.

Engine and Propeller.

  After trying various different engines, Mr. Moore-Brabazon finally selected an E.N.V. motor of 50-h.p. It is an engine of the 8-cyl. "V" type, and of very substantial construction, although specially designed for flight.
  The propeller is mounted direct on an extension of the crank-shaft, and is a two-bladed construction in steel. The blades are riveted to detachable arms, which are bolted to a separate boss in a manner which is clearly illustrated in an accompanying sketch. Some observations on the pitch and efficiency of the Voisin propulsion will be found in FLIGHT, vol. 1, p 16. In front of the engine, and immediately behind the pilot's seat, is a large honeycomb radiator.
  The engine is mounted on a light girder framework of steel, an arrangement which is well illustrated in the accompanying photographs.


  The control of the Voisin flyer is carried out entirely by the aid of the elevator and the rudder, the former being operated by pushing and pulling the steering wheel bodily to and fro, and the latter by turning the wheel upon its axis. The steering follows the same direction as on a motor car; pulling the steering wheel tilts the front edge of the elevator for temporary ascents. The purpose of the elevator is to produce temporary ascents or jumps by altering the angle of incidence of the main planes to the relative wind, and also to check any longitudinal oscillations which may occur, The elevator, although a means of beginning an ascent, is not itself endowed with any capacity for causing ascent to be maintained, that alone can result from an increase in the engine power beyond what is necessary to sustain horizontal flight. Lateral stability is maintained by suitably steering the machine, so as to give the depressed wing tip such an increased relative velocity to the air as will cause it to have a greater lift.

The Chassis.

  The weight of the machine, with the exception of that part represented by the tail, which is independently supported by a pair of small wheels, rests upon two bicycle wheels shod with 650 by 65 mm. tyres. These wheels are mounted upon a tubular framework, and have a. track of 4 ft. 8 1/2 ins. They are so arranged that they can swing, together, to one side or the other of their normal position, like the castors of a chair, a feature which is essential in order to preserve the equilibrium of the machine when it runs along the ground. In order to restrain these movements on the part of the wheels, their hubs, which are joined by a hinged axle, are anchored to the chassis frame by tension springs, which always tend to draw the wheels back again to their normal positions.


  The suspension of the flyer upon the chassis is effected by a pair of long helical springs. Each spring is mounted about a steel column which extends upwards from the chassis and passes through a bracket attached to the girder frame which carries the engine. This bracket serves as an abutment to the upper end of the spring, and it also carries a rubber pad to cushion the effect of the recoil. This point forms one of the attachments of the chassis to the frame, the other attachment being formed by a radius-rod which is hinged directly to the frame at a point further in front. When the springs compress, the effect of these radius-rods is to cant the uprights about which the springs are mounted, a point which should be borne in mind when considering the stresses to which the supporting brackets are liable to be subjected.

Pilot's Seat.

  The pilot's seat in the Voisin flyer is situated about a third of the chord behind the leading edge of the main plane, and is contained within the girder frame which carries the engine and the elevator. On Mr. Moore-Brabazon's machine the seat consists of a simple board, hinged so that it can be raised for access to the starting handle of the engine, which lies almost immediately beneath it. The relative position of the seat to the other principal members is clearly shown by an accompanying sketch.

Girder Work.

  From a constructional point of view a flyer presents a series of special problems in girder work, and it is therefore always instructive to consider the design on this basis. The main planes of the Voisin machine constitute together a kind of lattice girder, in which vertical wood struts alternate with diagonal piano-wire ties. Here and there extra struts and tie-wires have been introduced in the manner illustrated by an accompanying diagram which shows the staying of the main spars forming the leading edges of the decks.
  A point which is always of considerable importance to observe in this connection, is the continuity or otherwise of of the girder from end to end, and special attention should therefore be paid to the manner in which the lower spars of the main decks are carried across through the supplementary frame used for the engine. In the Voisin construction the front spar is divided at this point and fastened to the engine girder by a bracket, an intermediate member belonging to the girder bridging the gap.
  Another example of girder work in the Voisin flyer is the outrigger carrying the tail, but this consists of four rectangular spars attached by brackets to the rear transverse spars of the main decks. Each pair of spars in a vertical plane constitutes a lattice girder, and is braced in a similar manner to the spars in the main decks. There as no bracing, however, between the spars in a horizontal plane, other than that afforded at each end by the tail and the main decks respectively.
  The girder, to which the chassis is attached, which carries the engine, the pilot's seat, and the elevator, is a semi-elliptic construction formed by four longitudinal spars braced together by wood struts and diagonal wireties. In the vicinity of the engine tubular steel struts are used instead of ash, and the blank end of the girder is finished off with a pressed steel member, which braces three sides simultaneously.

Constructive Detail.

  Considerable attention has already been given to the joints and fastenings of the Voisin flyer in other issues of FLIGHT, so that our readers are already familiar with the aluminium socket-brackets by means of which the struts of the machine are fastened to the spars. This in itself is a feature of the Voisin construction not alone as a detail but also because of the rigid system which it represents. The joints in the Voisin flyer are designed to be quite rigid throughout, and the tie-wires have tighteners fitted to them, so that they can always be kept taut. On the contrary, the Wright flyer has hook-and-eye joints between the struts and the spars, and the tie-wires are not specially stretched in place; the whole machine is, in fact, built so as to be slack, and therefore able to give when strained.


  Ash is used throughout in the construction of the machine, with the exception of the steel tube work employed in the chassis. As timber, ash is characterised by its flexibility, and on the Voisin machine it must be confessed that there is not lacking evidence of its capacity in this respect, many of the struts and spars being very much inclined to bend under the load imposed upon them. In flying machine design every effort is, of course, made to keep down the weight, and sections have to be reduced to a minimum in consequence.
  For the small fittings such as the socket-brackets for the struts, aluminium is employed, and this metal was also used for the main supporting brackets above the springs, until it gave way during a rough landing. Messrs. Short Brothers then introduced a pair of manganese steel brackets when making the repair, and as these members are in any case not large, the increase in weight is in no way comparable with the value of the additional strength thus obtained for such an important member
  The fabric used for covering the decks is Continental rubber-proofed material.


  Most of the important dimensions likely to be of primary interest to the reader are given on the full-page plan and elevation. There are a few others, however, which it may be of interest to summarise here. The spacing of the ribs in the main decks is approximately 1 ft. 3 ins.; their camber is given by an accompanying diagram. The main transverse spars in the decks are 1 1/2 ins. fore and aft and 3/4 in. deep, but the section is not symmetrical, being cut away to sharpen the leading edge. The ordinary ribs have a section of about 5/16 in. by 3/4 in., while the main ribs of the section are 1 1/2 ins. wide at the base. The struts have a maximum width of 1 1/2 ins. and a maximum depth of 2 ins. They taper slightly towards the extremities, and have a sharp-pointed elliptic section. The longitudinal spars forming the outrigger which carries the tail have a mean section of 1 1/2 x 1 x 1 1/4 ins., while the main spars in the central girder which carries the engine and elevator have a section 1 1/8 ins. square. The ribs in the elevator are spaced 1 ft. 4 1/2 ins. apart.
  The smallest wire used has a diameter of about 1/16 in., but their size varies in different places and is much larger where it is employed for staying the chassis. The tubular steel work of the chassis is mostly 1 1/4 ins. in diameter. The helical springs used in the suspension are 3 ft. long, 2 ins. mean diameter, and of 3/4 in. circular section.

The First Lady Flyer.

  YET another sphere which some had thought man would, for some time, at any rate, retain for his own has been invaded by the gentler sex. Baroness La Roche has been successfully piloting a Voisin biplane, and has thereby earned the right to be known as the first lady flyer or "aviatress." For some time the Baroness has been taking lessons from M. Chateau, the Voisin instructor, at Chalons, and on Friday of last week she was able to take the wheel for the first time. This initial voyage into the air was only a very short one, and terra firma was regained after 300 yards; but on the following day the parade ground at Chalons was encircled twice, the turnings being made with consummate ease. During this flight of about four miles there was a strong gusty wind blowing, but after the first two turnings the Baroness said that it did not bother her, as she had the machine completely under control.

Flight, July 5, 1913.


  Very few people either appreciated or really realised what the Wright brothers had done, for they invited no publicity and most of their achievements were, in fact, unseen. It was, therefore, in France during the year 1907 that the new art first publicly attracted the notice of the man in the street.
  Henry Farman and Leon Delagrange were the central figures of this period in the history of aviation, and it is curious, but none the less a fact, that no one at that time gave much thought or credit to the Voisin brothers who had designed and constructed the machines that these pilots were using.
  Gabriel Voisin was in fact one of the earliest experimenters in aviation, and some of his most exciting experiences were concerned with the flying of a glider as a kite while it was being towed by a fast motor boat over the Seine.
  It was at this earlier period, too, that the names of Archdeacon, Bleriot, Santos Dumont, and Esnault Pelterie were first prominent, but this progress was spasmodic in the extreme, mainly because everyone found an exceeding great difficulty in selecting a suitable place for full-scale research. It was one thing to be interested in the idea of flying, but quite another to find anywhere that one could safely attempt to practise the art of flight.
  Santos Dumont, always an enthusiast for new things, and at that time still enamoured of the small dirigible, built an aeroplane of the tail-first type, with which he succeeded in winning the first flight prize for a glorified jump exceeding 25 metres, which he performed on October 23rd, 1906.
  As we have remarked, however, serious public interest was not really aroused until 1907, when Delagrange and Farman acquired their machines from Messrs. Voisin, who had established the first aeroplane factory on the outskirts of Paris. Permission had been obtained from the authorities by Henry Farman to practise on the parade ground at Issy, and it was apparent from the first that aviation was about to enter upon a new era.
  France has ever justified herself as a great society of encouragement, for new arts have seldom lacked the enthusiastic patronage of the rich in that country. In aviation there had already been established, through the generosity of MM. Deutsch and Archdeacon, a prize of 50,000 francs for whosoever should first complete a circular flight of 1 kilometre in length; nothing could well have been better suited to encourage progress. The conditions were simple and straightforward, yet they comprised a crucial test. It was apparent that the mere ability to keep the machine off the ground for a period while it wended its way more or less in a straight line, did not constitute flying. In order to fly properly, one must be able to turn, and it was while turning that the machine was most potent to cause trouble.
  Henry Farman won this Deutsch-Archdeacon prize, which was called the Grand Prix de l'Aviation, on January 13th, 1908. On October 31st of that year, he flew across country from Chalons to Rheims, a distance of 27 kilometres.
