Launched in 2003, the new-generation Ardiden covers a power range of 1,400 - 2,000 shp and is intended for use in five-to-eight ton single and twin-engine helicopters. The engine is particularly well-suited to demanding mission profiles, delivering sustained performance in hot-and-high conditions.

The Ardiden range features a remarkably compact modular architecture. The gas generator includes two centrifugal stages attached to a reverse-flow combustion chamber, a single-stage gas generator turbine and a two-stage power turbine. This design ensures that the engine remains very cost-effective, particularly in terms of maintenance and cost of ownership.

All Ardidens are equipped with the latest-generation, dual-channel Full Authority Digital Engine Control (FADEC). The Ardiden family is divided into two groups: the Ardiden 1, which offers 1,400 shp with growth potential to 1,700 shp, and the Ardiden 3 (in development), covering 1,700 to 2,000 shp.

Today, over 220 Ardiden 1 are in service throughout the world. They are installed in the Druhv, LCH (Light Combat Helicopter) and LUH (Light Utility Helicopter), all built by India's Hindustan Aeronautics Limited.; Russian Helicopters' Ka-62; and the AC352 from China's AVIC Helicopter.

Ardiden 1H / 1U

Incorporating innovative propulsion technologies, the Ardiden 1 family delivers 1,400 shp. There are currently two models: The 1H1 which powers the twin-engine Druhv and LCH (Light Combat Helicopter) from India's Hindustan Aeronautics Limited; and the 1U, fitted to its single-engine LUH (Light Utility Helicopter).

The Ardiden 1H1 obtained European certification in 2009 and over 250 units have already been co-produced with HAL, under the designation ‘Shakti'.

The Ardiden 1U underwent first bench tests in December 2014. First units have been delivered to HAL and EASA type certification is scheduled for 2017.
