The Nord 1750 Norelfe was a 1950s French three-seat helicopter built by Nord Aviation and designed by Jean Cantinieau.
Development
The 1750 Norelfe was based on the Matra-Cantinieau MC-101A, an earlier helicopter designed by Jean Cantinieau. It had a single main rotor, with torque control through a movable duct at the end of the tailboom. Powered by a Turbomeca Artouste turboshaft, the first of two Norelfes flew on 28 December 1954.[1]
The company sold the two helicopters and the design rights to Aerotécnica of Spain who redesignated them the Aerotécnica AC-13A.[1] Aerotécnica went on to produce a larger five-seat version, the Aerotécnica AC-14 which was used by the Ejército del Aire (Spanish Air Force).
