The Aviméta 88 was an all-metal French two-seat reconnaissance-fighter or heavy fighter tested in 1927.
Design and development
Aviméta, (Société pour la Construction d'Avions Métallique)‚ grew out of the Aeronautical Department of the Schneider-Creusot arms manufacturer.[1] Both the frame and the corrugated covering of the Aviméta 88 were made from Alferium, an aluminium-iron alloy developed by Schneiders.[1]
It was a parasol aircraft, with wings of constant chord and with slightly pointed, semi-elliptical tips. The thin-airfoil-section wings were built around two lattice girder spars and had a skin thickness of 300 μm. There was a large, trapezoidal cut-out in the trailing edge to improve the view from the cockpits. Its aileron hinges were set at a shallow angle to the trailing edge.[2]
The wings were braced to the fuselage with a parallel pair of struts from the lower longerons to the spars at about mid-span assisted by N-form, cross-braced jury struts at right angles. Four very short struts from the upper fuselage longerons to the wing centre section formed a low cabane.[2][3]
The square-section, rounded-cornered fuselage was built around these four longerons and a set of diagonally braced formers.[1] The Aviméta's 444 kW (595 hp) Hispano-Suiza 12Hb water-cooled V-12 engine[4] was in a pointed nose, driving a two-blade propeller. There were two open cockpits, with the pilot forward at mid-chord and the gunner/observer behind in line with the trailing edge. Behind the cockpits the fuselage tapered rapidly in profile to a conventional empennage, with the tailplane mounted at mid-fuselage. Both horizontal and vertical surfaces were strongly tapered, particularly on the leading edges, with a broad tailplane and fin but with small, inset elevators and rudder.[1][2] The Aviméta 88 had independent bungee-sprung wheels on legs enclosed in tapered trouser fairings attached to the lower longerons at the bottom of the wing struts.[2][3]
The Aviméta 88 was on show at the December 1926 Paris Aero Salon.[1] It may not have flown by that date, and rather little is known about its later history, though it gave a "pretty impressive" display at Villacoublay in September 1927.[5] Development was terminated when the official call for a two-seat fighter-reconnaissance aircraft was rescinded.[4]
