Aerospatiale Alouette II & Lama
Alouette II and Lama were one of the first turbine powered helicopters that remain in active service in considerable numbers over the world.
Alouette II was built using the base model Sud-Est SE-3120 Alouette which had its maiden flight on March 12 1955. At its famed peak, it was the bestselling of all west produced helicopters. The twin prototype models were fuelled by Salmson 9 piston engines. Alouette II was made available for use of French armed forces in 1957 and certification for civil use was obtained in January, 1958.
Sud-Est was acquired by Sud in March, 1957 and later both were purchased by Aerospatiale in January 1970. The SA-3180 was built from the experience of the Alouette II and was driven by a relatively powerful TurbomÃ©ca Astazou (later renamed as SA-318C in 1967). Its maiden flight was on January 31 1961. The Alouette II and Alouette II
Astazou did not differ much except for a 395kW (530shp) Astazou IIA derated to 270kW (360shp) in the Alouette II that led to an increased speed and takeoff weight.
The Indian army used the SA-315B Lama as a utility aircraft with improvements over hot and high performance. It was known as the Cheetah in India. The Lama was unique because it incorporated the twin competencies of the Alouette's airframe with the larger Alouette III's dynamic components including Artouste IIIB engine. The Lama flew for the first time on March 17 1969. Production numbers indicate 407 units that were produced by Aerospatiale till 1989, Hindustan (HAL) in India continues limited licence production and named as the SA-315B Cheetah, and seven were produced in Brazil as the Helibras HB-315B Gaviao.
