The North 500 Cadet was an experimental VTOL - convertible aircraft of the French manufacturer Nord Aviation in the 1960s.
history
The project was first presented to the public at the 1965 Paris Air Show , where a full-scale dummy was shown. Only two prototypes were built, the first of which was used for ground testing, and the second only performed a tethered hover in July 1968 before the project was abandoned.
construction
The Nord 500 was a small single-seat VTOL aircraft that was able to take off and land vertically using two tilt rotors - which were designed as ducted propellers . The closed fuselage gondola was equipped with an ejection seat . The tail unit sat at the end of a short, high tail unit beam. This also contained two Allison T63 propeller turbines arranged side by side, each with an output of 317 hp. The turbines served as a drive for two three-bladed (later five-bladed) jacketed pusher propellers, which were connected to one another by a shaft. The wave ran through a stub wing that carried the two propellers, but was also intended to provide aerodynamic lift in forward flight. The ducted propellers, together with an associated short part of the stub wing, could be tilted for vertical take-off and vertical landing.
The control devices in the cockpit were conventional, so the control around the yaw and pitch axes was carried out by differential or collective adjustment of guide vanes at the rear end of the propeller casing. The control around the roll axis takes place via a thrust modulation .
