Arsenal VB 10

The Arsenal VB 10 was a French fighter-interceptor aircraft developed during and shortly after World War II. It was a low-wing monoplane with retractable tailwheel undercarriage and of largely orthodox configuration. The ultimate product of a design that began with the Arsenal VG 10 prior to the war, the VB 10 added a second engine behind the cockpit which drove a second propeller, coaxial with and contra-rotating to the propeller driven by the engine in the nose.
In January 1937 Arsenal were given a contract to develop a twin-engined heavy interceptor built from wood, powered by two 590 hp Hispano-Suiza 12X engines mounted in tandem inside the fuselage, driving co-axial propellers in the nose. Work on the VG 10 was abandoned in June 1937 in favour of the VG 20, which was essentially similar but powered by two 900 hp Hispano-Suiza 12Y engines. The VG 20 was abandoned in turn in January 1938, but the design work and studies were used for the design of the all-metal VB 10. For research in the development of the VG 10 and VG 20, Arsenal designed and built the VG 30 powered by a single 690 hp Hispano-Suiza 12X engine, which in turn led to the high-performance fighter prototypes of the VG...
