VFW-Fokker H3 Sprinter

The VFW-Fokker H3 Sprinter was a single-engined experimental rotorcraft designed and built in West Germany. Two aircraft were produced by VFW-Fokker in the early 1970s, registered D-9543 and D-9544. Intended as the first of a family of tip-jet driven helicopters the two H3 prototypes flew briefly but the method of rotor propulsion was found to be unsuccessful for this size of aircraft. Due to a high rotor overspeed, they could perform jump take-offs to 280 feet (85 m) at a rate of 1,600 feet (490 m) per minute.[1] An improved H4 variant was designed but not built.
