For many years French engineer M Payen was engaged in the research and development of the delta wing. Seen here is one of his futuristic pre-war designs, the Type 112G. He was still at it after the war and on January 22, 1954 his PA.49 experimental single-seat jet-propelled delta-wing monoplane made its first flight. The all-wooden aircraft was powered by a Turbomeca Palas turbojet engine and with fixed landing gear could scuttle around at 310 m.p.h.
TANDEM SESQUIPLANE is perhaps the best description of this projected French Payen Flechair single-seater fighter, which will have two 100 h.p. Salmson engines driving concentric airscrews. There is one main landing wheel under the fuselage and auxiliary skids at the tips of the "tailplane." The maximum speed at sea level on only 200 h.p. is estimated to be 285 m.p.h. and the landing speed 50 m.p.h.
