TheAerotécnica AC-14 was a Spanish five-seat light helicopter of the 1950s, designed byJean Cantinieau, based on enlarging hisNord Norelfe design.
The AC-14 continued the Cantinieau practice of mounting the engine forward of the main rotor, and like the Norelfe, used the ducted exhaust from the turboshaft to counter the torque of the main rotor at low speeds, while at high speeds the exhaust gases were deflected rearwards to increase speed, torque being compensated for by movable twin tail fins.[1]
The first of prototype flew on 16 July 1957.[1] TheSpanish Air Force placed a pre-production order for ten machines where they served for a short time under the designationEC-XZ-4. No full production ensued, as they were much more expensive than second-handBell 47G-2 and G-3s.
