Aerotecnica Sa AC-13A

Nord 1750 Norelfe



Jean Cantinieau had been working on a three-seat turbine-powered helicopter, the designs for which he had sold to Societe Nationale de Constructions Aeronautiques du Nord (S.N.C.A.N.). Very similiar to the AC.12, SNCAN built two prototypes as the Nord N.1750 Norelfe with a large bubble canopy and a Turbomeca Artouste I turbine mounted above and behind the cockpit.

The three-blade rotor was positioned directly above the engine and had a rotorhead enclosed in a large spherical fairing. The tail rotor was replaced by a ducted exhaust gas controlled by the pilot through pedals.




The first Noreife prototype, F-WGVZ, was flown on 28 December 1954 but SNCAN 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.

The two prototypes were acquired by the Spanish Government.
