The Safran Ardiden is a 1,400–2,000 hp (1,000–1,500 kW) turboshaft designed and produced by Safran Helicopter Engines for 5–8 t (11,000–18,000 lb) single and twin-engine helicopters. Launched in 2003 as a more powerful TM 333, it first ran in 2005 and was introduced in 2007.

Development
In 1961, Turbomeca granted Hindustan Aeronautics Limited a manufacturing license for the Artouste turboshaft engine to equip the Indian HAL Chetak (Alouette III) and HAL Cheetah (SA 315B Lama) helicopters. By September 2000, HAL had contracted with Turbomeca to develop a more powerful version of the ALH's TM 3332B2, from . By January 2002, Turbomeca had begun developing the Ardiden TM3332C2 for helicopters, launched at the Paris Air Show for the LAH as the Shakti, co-developed and assembled by HAL, as the US lifted India's 1998 nuclear tests sanctions. The FADEC would manage both power and propeller pitch for operation up to 13,716 meters / 45,000 ft. The Tech TP compact, lightweight architecture targets a 15% lower fuel consumption over current engines. On 21 July 2020, a memorandum of agreement was signed between Safran and ZF, targeting flight testing of the 1,700-2,000shp (1,260-1,490kW) Ardiden 3TP from 2022.
