Aérospatiale N 500
The North 500 Cadet was an experimental VTOL aircraft change from the French manufacturer Nord Aviation from the 1960s.
History
The first presentation of the project to the public was made at the Paris Air Show in 1965, where a full-scale mock-up was shown. Only two prototypes were built, of which the first was used for ground tests, and only the second in July 1968 led by a bound hover before the project was abandoned.
Construction
The north 500 was a small single-seat VTOL aircraft that received his vertical take off and landing capability by means of two tilt-rotors, which were designed as ducted propeller. The closed fuselage gondola was equipped with an ejection seat. The tail unit was sitting at the end of a high-mounted short tail boom. This reflects two nebenaneinder arranged Allison T63 - propeller turbines were with an output of 317 hp. The turbines were used as drive for two three-bladed (later five-petalled ) coated pusher propeller, which were connected by a shaft. The shaft ran through a stub wings, carrying the two propellers in forward flight but should also provide aerodynamic lift. The ducted propeller could be tilted together with an associated short part of the stub wing for vertical take-off and vertical landing.
The control devices in the cockpit were the conventional type, the control was about the yaw and pitch axis by differential or collective adjustment of guide vanes at the rear end of the propeller shroud. A thrust modulation is performed, the control to the roll axis.
