History  Société Nationale Industrielle Aérospatiale
 Aérospatiale SA 318 Alouette II "lark"



On 12 March 1955, the prototype SE 3130 performed its maiden flight. The Alouette II was a widely used type and popular with operators, with over 1,300 rotorcraft eventually being constructed between 1956 and 1975. The type was predominantly used for military purposes in observation, photography, air-sea rescue, liaison and training, but it has also carried anti-tank missiles and homing torpedoes. As a civilian helicopter, the Alouette II has been used for casualty evacuation (with two external stretcher panniers), crop-spraying and as a flying crane, with a 500-kilogram (1,100 lb) external underslung load.

Design

The Aérospatiale Alouette II (French pronunciation: [alwɛt], "lark"; company designations SE 313 and SA 318) is a French light helicopter originally manufactured by Sud Aviation and later Aérospatiale. It was the first production helicopter powered by a gas turbine engine instead of the heavier conventional piston powerplant.

The Aérospatiale Alouette II is a French light helicopter, incorporating many innovations of its time. It was powered by a single Turbomeca Artouste II turboshaft engine capable of generating a maximum output of 400 hp. The speed of the main rotor is controlled by an automated fuel supply governor, eliminating the necessity of a twist-grip throttle and a conventional link between the throttle and the collective-pitch. Instead, the Alouette II uses a simple control lever arrangement, which acts to directly regulate the collective-pitch and actuate the governor while immediately and automatically applying the correct level of power to conform with flight condition. Without a clutch, the transmission is considerably simplified in both design and maintenance aspects
