Turbomeca announces the new Arriel 2+ family. The Arriel 2D, Arriel 2E and Arriel 2N, part of this new family, will respectively power the AS350 B3e, EC145T2 and AS365 N3e. This new family offers lower operating costs, higher reliability and higher performance.
Arriel 2D certification is scheduled mid-2011, the Arriel 2E’s one year later and Arriel 2N’s mid-2013.
Low operating costs
This new engines family (from 894 shp to 951 shp thermal take-off power) benefits from new technology in a proven engine. Its engines comprise five modules providing simplified maintenance at low cost.
Furthermore, this new family will offer better performances with lower maintenance costs. The comprehensive Direct Operating Cost will be also reduced, thanks to higher TBO (Time Between Overhaul), up to 4,000 hours at entry into service, then up to 6,000 hours at maturity.
The Arriel 2+ engines are 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, together with the blade-creep monitor, 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 composed today of 29 variants fitted on their corresponding helicopters. The Arriel family flying records total 30 Million flying hours, from Sahara to Antarctica.
