The Peyret Avionette was a low power, single seat French monoplane which won several first-place prizes at the Congrès Experimental contest of 1923.
The Peyret was a high, braced wing monoplane. Its two-piece wing was rectangular in plan apart from slightly angled tips; each part was built around two duralumin tube spars. The half-wings were braced by pairs of near-parallel struts from the lower fuselage longerons to the wing spars at about 60% span. Their full span ailerons had a constant chord of 370 mm (15 in).[1]
The Avionette was powered by an air-cooled, 750 cc (46 cu in), four-cylinder, upright inline Sergant A engine, which was geared down to produce 16 hp (12 kW) at 3,200 rpm.[1][2] It was enclosed in a duralumin cowling. Behind the engine the fuselage had a rectangular section, formed by four longerons connected with frames, and was plywood covered.[1] Its open cockpit was over the wing at mid-chord; a photo shows a streamlined headrest.[3] At the rear the fin was triangular and an integral part of the fuselage. It carried a roughly trapezoidal rudder working in a cut-out in the one-piece elevator, which was similar in plan to the wing and hinged behind its leading edge to provide aerodynamic balancing.[1][3] The control surfaces were deliberately large, to allow the Avionette to be flown as a glider.[1]
The Peyret had fixed tailskid landing gear with its mainwheels and associated bungee shock absorbers on a single, steel tube axle mounted on V-struts, wire cross-braced to each other, from the lower longerons.[1]
