The Focke-Wulf Project VII Flitzer ("streaker" or "dasher", sometimes incorrectly translated as "madcap") was a jet fighter under development in Germany at the end of World War II. DevelopmentThe 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 contemporary de Havilland Vampire.[2] Project V had the air inlets still positioned on either side of the nose, just below the 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 hypergolic liquid-propellant rocket was built in to give supplementary thrust. A complete mockup was built and all construction and assembly plans were finished, but the aircraft was not accepted by the Reich Air Ministry (Reichsluftfahrtministerium, RLM).[4] Specifications (design draft of 15 September 1944){{aerospecs|met or eng?=met |ref={{Citation needed|date=March 2010}} |crew=one pilot |capacity= |length m=10.55 |length ft=34 |length in=7 |span m=8.00 |span ft=26 |span in=3 |height m=2.35 |height ft=7 |height in=8 |wing area sqm=17.0 |wing area sqft=183 |empty weight kg=2,730 |empty weight lb=6,018 |gross weight kg=4,350 |gross weight lb=9,589 |eng1 number=1 |eng1 type=Heinkel HeS 011 turbojet |eng1 kn=14.7 |eng1 lbf=3,306 |eng1 kn-ab= |eng1 lbf-ab= |eng2 number=1 |eng2 type=Walter HWK 109-509 rocket |eng2 kn=16.7 |eng2 lbf=3,750 |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=955 |max speed mph=593 |cruise speed kmh= |cruise speed mph= |range km= |range miles= |endurance h=1 |endurance min=50 |ceiling m=13,000 |ceiling ft=42,500 |climb rate ms=18.2 |climb rate ftmin=3,600 |armament1=2 × 30 mm (1.18 in) MK 103 cannon |armament2=2 × 20 mm MG 151 cannon |armament3= |armament4= |armament5= |armament6= }} See also
