Early Single-Seat Monoplanes A, C and D (H.P.1, 3 and 4)

<...> For his first powered machine he may have been unduly bold in choosing a tractor monoplane, but it was cheaper to build than a Wright or Voisin-type biplane, and his primary aim was to fly at minimum cost. Nevertheless, he employed only the best quality spruce, ash, steel plate, piano wire and stranded cable in the construction of his first aeroplane.
   The wing, of Weiss’s patent shape, had a stiff inner box with four parallel spars and chordwise ribs, with flexible ribs extending radially from the outer ends of the spars. In view of the automatic stability claimed by Weiss, warping for lateral control was deemed unnecessary, and the inner ends of the spars were pinned to the top longerons and wire-braced above to a central vertical kingpost and below to the chassis. The fuselage was boat-shaped, with four longerons tapering to the stern; the two lower longerons converged halfway back to the tail, so that the rear fuselage section was triangular, and the two upper longerons were reinforced at the forward end to act as bearers for the 20 hp Advance vee-four air-cooled engine; a small petrol tank was strapped across the top longerons in line with the leading edge of the wing. The engine was direct-coupled to a 6 ft 6 in diameter two-blade airscrew copied by Handley Page from a design by Weiss for Lascelles & Co; Handley Page was not prepared to buy what he could make more cheaply himself and had begun selling his own popular range of airscrews, enabling him to undercut Lascelles’ prices. The control surfaces comprised a cruciform tail unit, combining elevator and rudder and mounted on a universal joint, as in Santos-Dumont’s Demoiselle. The wing, fuselage and empennage were covered with blue-grey rubberised fabric, and the chassis had a central channel-section ash skid, with a resilient ash cross-axle carrying a lightweight wheel at each end, having tension spokes radiating from wide hubs designed to resist side loads; the axle was stiff enough to carry the static weight while taxying and taking off, but flexible enough for the skid to take the main landing impact.
   This first monoplane, Type A or Bluebird, was still unfinished when exhibited on Stand No. 82 at the second Olympia Aero Exhibition in March 1910, with a price tag of ?375, and although the critics were kind no customers came forward. The general opinion was that the empennage was too small and, indeed, on its first trials the elevator power was insufficient to prevent the skid digging into the ground when the engine was opened up; but this was countered by reinforcing the axle and moving it 4 inches forward, at the same time adding a small triangular fixed tailplane. Thereafter the rudder was effective for ground steering at 15 mph and the elevator at 20-25 mph; but it was not until 26 May, 1910, that Handley Page became airborne, only to sideslip into the ground on his first attempt to turn across wind. This indicated the need for positive lateral control to correct overbanking, so during reconstruction Handley Page incorporated wing warping and enlarged the rudder. The single top kingpost was replaced by a twin-strut pylon; the axle was shortened and further reinforced, and the temperamental Advance was replaced by a 25 hp Alvaston flat-twin water-cooled engine driving a heavy square-tipped airscrew; a rectangular multitube radiator was mounted above the engine edge-on to the slipstream and slightly to the left of the centreline so as not to interfere with the pilot’s view. But the Bluebird, thus modified and now known as Type C, refused to fly in spite of its more powerful engine; so Handley Page next installed a 50 hp Isaacson five-cylinder air-cooled radial, which necessitated further strengthening of the fuselage front-end and chassis, the outer ends of the axle being braced to the upper longerons by struts incorporating rubber-cord shock-absorbers. This was completed late in 1910, by which time Handley Page had begun work on a new monoplane, Type D, so the modified Bluebird was set aside, eventually reappearing in the Northampton Polytechnic Institute’s aeronautical laboratory at Clerkenwell, as an instructional airframe.

Handley Page A / H.P.1

   The H.P.1 was a single-seat tractor monoplane built at Barking during the late summer of 1909. Its engine was the 25 h.p. four-cylinder air-cooled vee Advance which drove a two-bladed 6 ft. 6 ins. propeller. The tail unit comprised cruciform rudder and elevators pivoted together on one universal joint. The undercarriage axle was of specially selected very flexible ash in place of springs, with splayed wheels on strong 12 ins. hubs. The machine was named Bluebird on account of the blue-grey colour of its rubberized-fabric covering. Owing to being under-powered, the H.P.1 was not a success, but it rose from the ground for a few short hops on 26th May, 1910. Span, 32 ft. 6 ins. Length, 20 ft. 6 ins. Wing area, 150 sq. ft. Weight empty, 300 lb. Weight loaded, 450 lb. Maximum speed at sea-level. 35 m.p.h. Price, ?375.

Handley Page C / H.P.3

   The H.P.3 single-seat tractor monoplane was built during 1910 and was fitted with a 25 h.p. two-cylinder horizontally-opposed Alvaston engine. The cruciform tail unit combining rudder and elevators was mounted at the rear of the fuselage on one universal joint. The machine was displayed at the Olympia Aero Show of 1910. Later the 65 h.p. Isaacson radial engine was installed. Span, 30 ft. Length, 21 ft. Wing area, 150 sq.ft. Weight empty, 250 lb.

   MONOPLANE of the bird's wing type, designed somewhat on the lines of the Weiss model but fitted with a cross-tail serving the purpose of an elevator and rudder. This tail is one of the special features of the design, being mounted on a single pivot so arranged that it cants when steering; the object being to create a torque to assist in maintaining stability.
   The most interesting minor detail of this machine is the ash axle that carries the wheels upon which the machine is mounted. This axle is a specially selected piece of wood, and its natural flexibility is used as a substitute for springs. The wheels are splayed, and the wheel hubs have been made 12 ins. long in order to give great strength.
