Description: The Arrius is a family of turboshaft engines introduced in 1981 to power a wide range of rotary-wing single and twin-engine aircraft. Over 2,000 engines have been produced by Turbomeca (Safran Group) for 430 customers in 60 countries. These engines have logged more than 2.8 million flight hours so far. This engine family features extreme simplicity design and mainly consists of four basic variants: Arrius 1A/1M, Arrius 2F, Arrius 2B1/2B2 and Arrius 2K1/2K2. Power at take-off ranges from 479-shp to 716-shp.

The Arrius 2B2 entered service in mid-2002 and currently is powering Eurocopter's EC135 and EC635 twin-engine helicopters. Build around two engine modules, Arrius 2B2 develops approximately 40 percent more power than early Arrius models and has a Time Between Overhaul (TBO) of 3,500 hours. The Arrius 2B2 is controlled by an Electronic Engine Control Unit (EECU) which ensures automatic starting, over-temperature, over-torque, surge and flame-out protection as well as engine life-management functions.
