Turbomeca Artouste IIIB


The Turbomeca Artouste is an early French turboshaft engine, first run in 1947. Originally conceived as an auxiliary power unit (APU), it was soon adapted to aircraft propulsion, and found a niche as a powerplant for turboshaft-driven helicopters in the 1950s.

Artoustes were licence-built by Bristol Siddeley in the UK, Hindustan Aeronautics Limited in India, and developed by Continental CAE in the USA as the Continental T51. Power is typically in the 300 kW (400 hp) range.
