Launched in 2003, the new-generation Ardiden covers a power range of 1,400 to 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 250 Ardiden 1 are in service throughout the world. Ardiden 3G variant has been certified in June 2017.
Ardiden engines are installed in the Druhv, LCH (Light Combat Helicopter) and LUH (Light Utility Helicopter), all built by India's Hindustan Aeronautics Limited, and in Russian Helicopters' Ka-62 and the AC352 from China's Avicopter.
In 2011 the Ardiden 3G variant was selected by Russian Helicopters to power the Ka-62. It underwent first bench tests in 2013 and has received EASA engine type certification in June 2017. Ka-62 made its official maiden flight on 25 May 2017. Since its first ground test, the Ardiden 3 maturation and certification campaign has accumulated more than 8500 hours of test. Thanks to this extensive test phase, the Ardiden 3G will demonstrate a high level of maturity at entry into service.
Ardiden 3G engines represent a very effective combination of new and mature technologies, combining exceptional performance with low operating and maintenance costs, with a TBO (Time between overhaul) of 5,000 hours at entry-into-service. Ardiden 3G engines also deliver at least 10 % better fuel consumption over engines operating in the same power range.
