Nord Norelfe
French helicopter built by Nord Aviation
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.
The company sold the two helicopters and the design rights to Aerotécnica of Spain who redesignated them the Aerotécnica AC-13A. 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).

The public source identifies “Nord Norelfe” as french helicopter built by Nord Aviation. This brief keeps that definition visible, then builds a research path around Nord, Norelfe and French.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Nord Norelfe”, the useful work is to connect “french helicopter built by Nord Aviation” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 8, 2025. The linked authority identifier is Q3343567. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1750, 1954, 1958 and 1984.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
