Helicopter engine manufacturer Turbomeca (Hall 2A A232) is busy developing improved models for new Eurocopter variants in the light-single and medium-twin helicopter categories, as well as an engine family that will power China’s and Russia’s forays in medium twins.

The new Arriel 2+ family has three versions–2E, 2D and 2N–Philippe Couteaux, vice president and general manager, airframers, explained. The newer engines feature an improved axial compressor and single-crystal, high-pressure turbine blades.
