The Pottier P.40 was the first of Jean Pottier's many designs,[1] begun around 1967, though not the first to fly as the P.70 flew in August 1974.[2] Construction of the P.40 by Bela Nogrady was started in 1968 but the first flight was not made until 1975.[3]
The P.40 is a tailless aircraft with a swept, cantilever, low wing. In plan, the wing has a rectangular centre section and straight tapered outer panels with elevons. There are wing tip fins and outward opening rudders which extend a little below the wing.[1]
The short fuselage is flat sided, mostly occupied by a long canopy over the single seat cockpit. The engine, a 19 kW (25 hp) Volkswagen 1.2 litre air-cooled flat-four, is in the rear in pusher configuration.[1] The P.40 has a low, fixed, faired bicycle undercarriage.
The first P.40 made only one short flight and was then destroyed.[1][4] The history of the one surviving example, OO-68, on display in the Belgian Royal Museum of the Armed Forces and Military History in Brussels is obscure. The two machines differed a little, with varying engine cooling and exhaust arrangements, and OO-68 has a three, rather than two, blade propeller.
