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.
The Ardiden 3G will power the Russian Helicopters Ka-62. It underwent first bench tests in 2013 and will complete certification testing in 2015.
The 3G is characterized by excellent reliability, low-cost maintenance (TBO 5,000 hours on entry-into-service and 6,400 hours once mature) and extremely low fuel consumption (at least ten per cent less than other engines in the same power range).
