Eurocopter celebrates the 50th Anniversary of the maiden flight of the Alouette 2, the first turbine-powered helicopter to enter series production

On 12 March 1955, the Alouette 2 prototype took to the air for the first time from the Buc airfield near Paris. It went on to become the very first turbine-powered helicopter in series production in the world.

This astounding saga saw the light of day in the 1950s when the helicopter's two designers, Charles Marchetti and René Mouille, made the decision to abandon the Alouette 1 equipped with a somewhat "lethargic" piston engine for a helicopter powered by a gas turbine. At the time, Turbomeca had developed two gas turbines: the initially selected Artouste 1 developing 250 hp, and the Artouste 2, which the company president and founder, Joseph Szydlowsky, finally agreed to cede to the two designers.

The engine proved its worth in bench tests, and the SNCASE  Design Office   based in La Courneuve and one of Eurocopter's ancestors   decided to design a new airframe around the Artouste 2.

This is how the SE 3130 – 01 found itself on the Buc airfield on the morning of 12 March 1955 to make its first flight, with Chief Test Pilot, Jean Boulet, at the controls and Flight Test Engineer, Henri Petit, monitoring the instruments.

The flight was an all-round success that would revolutionize helicopter design. With such a power-to-weight ratio, the helicopter's performance opened up a wide variety of operating possibilities and made it into the fantastic tool it is today.

On 25 May, a second prototype took to the air. The promising results from both machines prompted an attempt on the altitude record. Thus, on 6 June 1955, before a blue ribbon panel of officials and commissioners, Jean Boulet pushed the Alouette 2 up to a record altitude of 8,209 meters.

Just 13 months after the prototype's maiden flight, the first production Alouette 2 lifted off.
In 1957, the SGAC – the certifying agency at the time   awarded the helicopter its Certificate of Airworthiness.

In 1961, the Alouette was rejuvenated with a more powerful gas turbine engine   the more fuel-efficient Turbomeca Astazou 2 developing 530 hp. The new version was named SA 3180 Alouette 2 Astazou.

Production of the helicopter was finally stopped in 1975 when the 1324th machine was delivered.
The 284 Alouette 2s still in service logged 27,000 flight hours in 2004.
