The Aérospatiale Gazelle (company designations SA 340, SA 341 and SA 342) is a five-seat helicopter developed and initially produced by the French aircraft company Sud Aviation, and later by Aérospatiale. It is the first helicopter to feature a fenestron tail instead of a conventional tail rotor, as well as being the first helicopter to be adapted for single-pilot operations under instrument flight rules.

Design

The Gazelle was developed during the 1960s as a successor to the Alouette II as well as to meet a French Army requirement for a new lightweight observation helicopter. Both France and the United Kingdom worked on the project via a joint production and development agreement with Westland Aircraft. The Gazelle is considerably larger than the preceding Alouette series, yet is still powered by a single Turbomeca Astazou turbine engine. Innovations in the design of the Gazelle, aside from the fenestron, included an emphasis on minimal maintenance requirements from the onset of development and the use of a semi-rigid composite rotor system, the latter having required considerable development time. On 7 April 1967, the Gazelle performed its maiden flight.
