Fw Project VII
Wartime model of the Project VII design
Number built One mock-up built and a few prototype sub-assemblies completed
Focke-Wulf Project VII ("streaker" or "dasher", sometimes incorrectly translated as "madcap") was a jet Flitzer fighter under development in Germany at the end of World War II.
Development [ edit ]
The design began as
Focke-Wulf Project VI which had a central fuselage and two booms carrying the rear control surfaces having great similarity with the de Havilland Vampire. Project V had the air inlets still positioned on either side of the nose, just below the [2 ] cockpit. [3 ]
The estimated horizontal speed was not satisfactory and in the next development,
Project VII, the jet intakes were situated in the wing roots. Further improvements over Project VI were a narrower fuselage and a changed pilot's canopy. In order to improve the rate of climb, a Walter HWK 109-509 liquid rocket was built-in. In spite of the fact that a complete mock-up was built and all construction and assembly plans finished, the aircraft was not accepted by the RLM (Reich Air Ministry, or . Reichsluftfahrtministerium) [4 ]
