Arsenal VG-70

The Arsenal VG -70 was a French swept wing experimental aircraft the Arsenal de l' Aéronautique.

History

The plane took off on 23 June 1948 maiden flight. The VG -70 was a direct derivative of the German Messerschmitt P.1092, which designed from 1943 as a project, however, was never built. The unique similarities between the two designs, the comparable dimensions and the use of a German Jumo 004 jet engine to this conclusion. In addition, in 1943 conducted by the Messerschmitt employees wind tunnel tests with the P.1092 in the French Chalais Meudon wind tunnel. Have documentation on this project must be after the war, the French designers, such as Jean Galtier, who later designed the Nord 1500 Griffon II, were produced before.

Construction

The VG -70 was a cantilever mid -wing monoplane of all-metal construction with retractable tricycle frame. The engine was largely housed in the fuselage below the wings. The air intake was designed crescent- shaped and started behind the cockpit conclusion on the lower side of the fuselage. In the front very slender fuselage, the cockpit and the nose landing gear were housed. The normal tail formed the hull statements. The broad-gauge main landing gear was attached to the wing and drove into the palms inward one. The swept-back wings at 35 ° corresponded largely the then draft Messerschmitt.
