The Wibault 7 was a 1920s French monoplane fighter designed and built by Société des Avions Michel Wibault. Variants were operated by the French and Polish military and built under licence for Chile as the Vickers Wibault.
Development
Developed from the earlier Wib.3 the Wibault 7 was a C.I category single-seat high-wing braced parasol monoplane fighter powered by a 480 hp (360 kW) Gnome-Rhone 9Ad radial engine. The main difference from earlier aircraft was the use of an all-metal construction system which was patented by Wibault. The first prototype flew in 1924, and was followed by two more prototypes. Despite being placed only third in the competition (behind the Nieuport-Delage NiD 42 and the Gourdou-Leseurre GL.32), an order for 25 Wib.7s was placed in January 1927.[1] These were followed in production by 60 aircraft for the Aéronautique Militaire as the Wib.72 which entered service in 1929. 26 Wib.7s were built for Chile under licence by Vickers in England. Plans to sell the aircraft to Poland did not come about, but the PZL company bought a licence and manufactured 25 aircraft with Bristol Jupiter engines, designated in Poland as Wibault 70C1, to the Polish military.[2] One or two of them were fitted with Wright Cyclone engine.[2] The next variant was the Wib.73, with seven built for Paraguay. The French Navy bought some carrier-capable Wib.74s with a strengthened fuselage and arrestor hook.
