The Ardiden is the latest member of the Turbomeca engine family. Its first application is the Dhruv twin-engine helicopter (formerly called the ALH - Advanced Light Helicopter) from HAL (Hindustan Aeronautics Ltd) of India.
Turbomeca has developed a new turboshaft engine with a completely different design concept. The Ardiden features a simple, modular and compact design.
It is built around a gas generator with two centrifugal compressor stages, coupled to a single-stage high-pressure turbine. The power turbine comprises two stages. The engine is controlled by a dual-channel Engine Electronic Control Unit (EECU). With its simple and modular design, the Ardiden offers very low cost of maintenance and ownership. It is designed to develop a power from 1,200 to 2,000 shp and satisfy the most demanding mission requirements, while retaining full performance under high altitude and hot temperature conditions.
The Ardiden is intended for helicopters in the 5 to 8-ton class. For its first application, the Dhruv, a first engine variant christened the Ardiden 1H1 (or "Shakti" in India), offering a power of 1,400 shp, is jointly developed and producted with HAL. The Ardiden 3, from 1,700 to 2,000 shp, is dedicated to 6 up to 8 tons helicopter market. It has already been selected by China and Russia to power respectively the AC532 and Ka-62 helicopters.
