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 (formerly Blackburn) in the UK, Hindustan Aeronautics Limited in India, and developed by Continental CAE in the US as the Continental T51. Two major versions of the Artouste were produced. The Artouste II family, mainly used in the Aérospatiale Alouette II helicopter, had a one-stage centrifugal compressor and a two-stage turbine, with gearbox-limited power of 300 kW (400 hp). The Artouste III family, mainly used in Aérospatiale's Alouette III and Lama helicopters, had a two-stage axial-centrifugal compressor and a three-stage turbine, with gearbox-limited power of 420–440 kW (560–590 hp).

El Turbomeca Artouste fue un motor turboeje francés desarrollado en el año 1947. En 1950 Artouste era el mayor pionero del mundo en los motores turboejes. Esto hizo posible el Sud-Aviation (más tarde se convertiría en Aérospatiale) Alouette, el primer motor turboeje producido en masa en el mundo. El motor pronto se desarrolló se mejoró incorporándole el compresor axial y tres escalones de turbina. Gran número de Artouste II y Artouste III todavía están en operativo
