The Turbomeca (Safran group) Arriel 2D engine, with a take-off power of 950 shp, has been certified by the European Aviation Safety Agency (EASA).
The Arriel 2D will power the Eurocopter AS350 B3e helicopter. The first engines entry into service is scheduled in the second half of 2011.
Low operating costs
The Arriel 2D benefits from new technology (new axial compressor, new blade material, etc.) in a proven engine. This new engine offers better performances with lower specific fuel consumption, resulting to lower operating costs.
Its modular design, combined with a higher TBO (Time Between Overhaul), up to 4,000 hours at entry into service, then up to 6,000 hours at maturity, allow a simplified maintenance at low cost.
The Arriel 2D engine is controlled by a new-generation dual-channel FADEC, a benchmark for efficient power control, reducing pilot’s workload and increasing safety.
The new Engine Data Recorder further shifts the emphasis from traditional to preventive maintenance. These innovations also drastically reduce unscheduled removals and significantly improve helicopter availability.
The increased thermal power, the new design of many of its components enhances its already high performance and ensures that the Arriel remains the most reliable engine in its class.
Since 1978, Turbomeca has been producing 10,000 Arriel engines. The Arriel family flying records total 32 Million flying hours with 430 customers in 60 countries.
Arriel 2D certification is scheduled mid-2011, the Arriel 2E’s one year later and Arriel 2N’s mid-2013
The Arriel 2E, with a take-off power of 950 shp, will power the Eurocopter EC 145T2 helicopter.
The new 1,100 shp engine is designed to power four- to six-ton helicopters and fits between the Arriel and Ardiden performance ranges.
