Austin Production

Single seat, single bay biplane fighter.The un-staggered, equal-span wings, had no dihedral but were slightly swept, as were the wingtips, and featured ailerons on the upper wings only. The large triangular tailplane featured split elevators, while the rudder was aerodynamically balanced; there was no fixed fin. An advanced feature was that the controls were operated by rods mounted within the airframe rather than cables carried externally. Armament consisted of two Lewis machine guns, one firing through the hollow propeller shaft, with the other mounted above the wing on a Foster mounting. One 200 h.p. Hispano-Suiza powerplant with side mounted radiators.

Single seat triplane fighter, of conventional wood and fabric construction, with single-bay wings, to meet Specification A.1(a). The staggered wings featured ailerons on all wings and had swept tips, as did the tailplane. The rudder was aerodynamically balanced; there was no fixed fin. Two synchronised Vickers guns were mounted ahead of the pilot, while a single Lewis gun was mounted on a movable mounting on the centre section of the middle wing, but with a very limited field of fire, the large diameter propeller blocking any forward fire. One 230 h.p. Bentley B.R.2 powerplant.

Two seat fighter-reconnaissance two-bay biplane to Specifications RAF Type lIl and Type IX. Of conventional all-wooden construction, the wings were staggered and of unequal span and chord, with ailerons on all wings, and had swept tips, as did the tailplane. The rudder was horn balanced and there was a fixed fin both above and below the fuselage. Armament included two fixed Vickers machine guns for the pilot, while the observer had a Lwis gun on a Scarff ring mounting. The aircraft was provided with dual control, along with a camera, wireless and, due to the increased altitudes being flown, oxygen and electrical heating. One 320 h.p. A.B.C. Dragonfly I powerplant.

Single seat touring biplane of mixed construction. The fuselage was a braced box beam of steel tubing, with no bracing wires. It was built up in two sections, being divided at a point immediately behind the cockpit; the forward section was fabric covered with ply upper decking, wthile the aft featured a rounded upper coaming, the whole fabric covered. The engine was cowled in aluminum. The single-bay, folding wings, which had a slight stagger of 3 inches and 5 degrees of dihedral, was fabric-covered and constructed of hollow box-section wooden spars, with steel tubes employed for compression members, and internal bracing by steel pianowire. Interplane struts consisted of one set of 'N' struts, of streamlined steel tubes, with the top centre section being supported above the fuselage by two pairs of vertical streamlined steel struts, only this portion of the wing being wire-braced. The wings were hinged at the roots of the rear spars to facilitate folding. When folded back, the wings were supported and locked by tubes attached to the.fuselage, and when in flying position were locked by a positive quickrelease locking device. Bracing for lift and incidence was by streamlined steel tubes, anchored at their lower ends to the roots of the lower wings and at their upper to the 'N' strut attachment points, were not disconnected when folding the wings. In order to correct incidence, the rear lift struts were made adjustable. Ailerons were fitted on all wings, which had swept tips. The strut braced tailplane was ground-adjustable for incidence, the elevators and unbalanced rudder framework was of steel tubing with wooden ribs .A triangularvertical fin was mounted both above and below the fuselage. One 45 h.p. Anzani powerplant.

Two seat, side-by side, touring biplane built for the 1920 Air Ministry Competition. The fuselage was a braced box beam of steel tubing, the two bay wings had ailerons fitted on all wings and had swept tips, as did the tailplane. The rudder was horn bbalanced and there was a fixed fin both above and below the fuselage. One 160 h.p. Beardmore powerplant.
