Safran Helicopter Engines has unveiled a new family of powerplants for military and commercial rotorcraft covering the 2,500 to over 3,000 shp power range.

The Aneto high power engine family was launched in early October and is said by the French-based company to feature “ground-breaking” technologies.

Developed via the Safran Helicopter Engines Research and Development (R&D) Roadmap, the Aneto-series covers several engine models for the super-medium and heavy helicopter market.

The first Aneto-1K engine is rated at 2,500 shp and has already been selected to power the AgustaWestland AW189K. The engine and helicopter combination flew for the first time in March and is slated to enter service in the fourth quarter of 2018.

As noted by the company, the engines should offer superior performance (25% more power compared with existing engines of the same volume is quoted) with reduced operating costs (Safran touts up to 15% in fuel savings), particularly in ‘hot and high’ operating conditions. The engines are also said to be more reliable than existing units, requiring less maintenance.
