Nord 1750 "Norelfe" 1968 |
SNCAN built two prototypes of this helicopter as the Nord N.1750 Noreife which was a rather futuristic all-metal machine with a large bubble canopy and a Turbomeca Artouste I turbine mounted above and behind the cockpit. The three-blade rotor was positioned directly over the engine and had a rotorhead enclosed in a large spherical fairing. The tail rotor was replaced by a ducted exhaust gas arrangement similar to that employed forty years later on the McDonnell Douglas NOTAR designs. This was controlled by the pilot through pedals. The three-seat Noreife prototype, F-WGVZ, was flown on 28 December 1954 but SNCAN was occupied with other projects and sold both the aircraft and the rights to Aerotecnica who designated them AC.13A. After further testing in Spain, Aerotecnica moved to a larger five-seat version known as the AC.14. R.Simpson "Airlife's Helicopter and Rotorcraft", 1998
