Short Tractor Monoplane

  During 1911, Short Brothers decided to explore the possibilities of the monoplane lay-out and, in November of the year, started to build a machine which resembled very closely indeed the standard Bleriot XI design. Their tractor monoplane was powered by the 50 h.p. Gnome and was a single-seater. The Bleriot-type wings were followed, but the tail unit was very square-cut in comparison. The main undercarriage was changed completely in design, with the main struts being mounted direct on to the upper longerons and without the characteristic springing arrangement of the Bleriot. The wings were warped in the usual manner for lateral control, and a fairly deep coaming was fitted to the front part of the upper fuselage before the cockpit.
  The monoplane was completed early in 1912 and was tested at Eastchurch during February by Commander C. R. Samson, R.N. Two months later it took part in the Naval Manoeuvres held in May, and bore the designation M2 on its rudder.

AIR EDDIES.

  Messrs. Short Brothers, who have hitherto only been associated with machines of the biplane class, have constructed a monoplane which was tested for the first time on Saturday morning last, by Commander Samson. That it should fly satisfactorily at the first attempt and need no subsequent adjustments, is testimony enough of the remarkable excellence displayed by that firm in both design and construction. This new machine, which, superficially has much in common with the Bleriot, we hope to describe fully next week.

THE SHORT MONOPLANE.

  WHEN a firm have been so conspicuously and successfully associated with biplane construction as have Messrs. Short Brothers, it is a little difficult to suddenly attune the mind to the idea of a Short monoplane. Difficult or not, however, a monoplane has lately issued from those excellent workshops at Eastchurch, and although its design admittedly owes much to a prototype that has served as a basis for more than one successful flyer, it has just as much of the Short originality as have those other typical aircraft with which the firm's name is associated. Strength and solidity, undoubtedly, were the chief points in the minds of the designers in the preparation of this new machine, and these features, too, are precisely those that the whole aviation world expects to see exemplified in any Short product.
  The main body is little different from that employed on the Bleriot, and the same system of bracing is used. At the front end, however, it is different, being arranged for the mounting of the engine without any support between the propeller and crank case, and for the application of the new type of undercarriage with which the machine is equipped. This latter is of the wheel and skid type. Two sturdy ash struts extend downwards and forwards from the points at which the main wing spars join the fuselage and are joined at their lower extremities by a horizontal planche. To this the two skids are applied, their rear ends being supported by subsidiary struts from the bottom of the main body. Diagonal struts further strengthen the structure.
  In common with other forms of landing gear of the same type, especially amongst those exhibited at the last Aero Show in Paris, the skids show signs of suppression. In many of the French machines referred to, the skids had grown so small that, were the wheels to fail, they could scarcely be relied on to provide that easy run over the ground necessary for the safety of the machine. In the Short chassis, however, this extreme is avoided.
  At the front end of the body is mounted the motor, direct coupled to a Chauviere type propeller, a hood being arranged above it so as to afford protection for the pilot against oil and exhaust products thrown off by it while in operation. The wings, much of the same size and shape as those of the Bleriot, are trussed to the landing chassis by eight strong stranded steel cables, four to each wing. So strong is the wing staying, that structural failure in this section of the machine would seem almost an impossibility. In their internal construction, too, pains have been taken to prevent the ribs having a tendency to split at the webs left by the drilling-out process. Warping is relied on to maintain lateral equilibrium, the rear spars being deflected by eight wires, four to each, proceeding from an inverted tower of steel tubing applied below the body. The weight of each wing, when the machine is stationary, is supported by four wires from a tubular cabane.
  Arranged before the pilot, so as to form a type of scuttle dash, are the fuel-tanks. These terminate in an inclined dashboard, where are fitted the switch, the petrol-gauge, and the oil feed-gauges, all well within reach of the pilot. A rectangular cambered surface, to the back of which is hinged a flap cambered in the reserve sense and serving as elevator, comprise the tail unit. This is supported clear of the ground, by a long universally-jointed skid attached to the body at the forward end by elastic bands. Both the rudder and the elevator are actuated by wires from the controlling organs attached to pressed-steel cranks. The controls themselves are almost identical with the original Bleriot system, a pivoted foot-bar operating the rudder and a universally-jointed vertical pillar, surmounted by a small hand-wheel, governing the machine's attitude and the wing warping. Indeed, the only difference noticeable is that the typical aluminium dome of the Bleriot control is replaced by simple steel cranks. Its flying speed is approximately 60 miles an hour.
