The meaning of «sfca maillet 20»

The SFCA Maillet 20 was a French three seat tourer built in 1935. The Armée de l'Air ordered 30 for training and liaison and several were raced. The aircraft was developed through 1935 via cockpit layout and canopy changes to the provision of retracting landing gear.

The Société Francaise de Constructions Aéronautiques (SFCA) was set up in July 1934 to build light aircraft designed by André Maillet,[1] though Maillet was killed in an aircraft accident on 30 June 1934.[2] The company's first design, the Maillet 20,[1] was a direct development of the earlier Maillet-Nening MN-A,[3] Maillet-Nening [4] or Maillet 01[5] built by Maillet and Nening, respectively chief pilot and chief engineer at the Roland Garros Aero Club,[4] which undertook its first test flights in December 1933.[6] Both aircraft were three seat, low wing monoplanes powered by Régnier 6 inverted inline engines.[4][7]

The cantilever wing of the Maillet 20 was an all-wood, two spar structure with plywood skin, finished with an outer fabric layer. It had a rectangular centre section and tapered outer panels with dihedral, ending at semi-elliptical tips. The inner wing carried split flaps.[8]

The fuselage structure was also wooden, with an oval cross-section and was ply and fabric covered like the wings.[8] Its 130 kW (180 hp), air-cooled, inverted six-cylinder inline Regnier R 6[7] was in the nose, driving a two blade, variable pitch propeller and with its fuel stored in the fuselage. There were three seats in tandem, with the pilot in front; dual control could be fitted and there was luggage space behind the third seat, large enough to hold three suitcases. The seats were enclosed under continuous multi-panel glazing which ran unbroken into the raised top of the rear fuselage, coupé fashion.[8]

The rear surfaces were constructed like the wings; the tailplane, attached halfway up the fuselage, could be adjusted on the ground and carried elevators with cut-outs for movement of a rounded, unbalanced rudder which reached down to the keel. The fin was straight-edged and round-topped.[8][9]

Though the MN-A and the Maillet 20 had much in common, one obvious difference was in the landing gear. Both designs had mainwheels on vertical legs from the outer part of the wing inner section but the earlier model also had diagonal V-struts from axles to lower fuselage,[3] whereas those of the Maillet 20 were cantilevers, without struttage. The legs had Messier oleo shock absorbers and mounted the wheels in forks. Both legs and wheels were enclosed in fairings.[8]

The Maillet 20 first flew on 24 March 1935, piloted by Louis Massotte.[10][11] Two were built.[10] The Armée de l'Air bought 30 examples of a very similar trainer version,[12] fitted with automatic two speed propellers,[13] designated the Maillet 201.[9]
