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. More than 2,700 engines have been produced by Turbomeca (Safran Group) for 430 customers in 60 countries as of early 2011. These engines have logged more than 5 million flight hours so far. This engine family features extreme simplicity design and mainly consists of five basic variants: Arrius 1A/1M, Arrius 2F, Arrius 2B1/2B2, Arrius 2K1/2K2 and Arrius 2G/2G1. Only the Arrius 2F/G/B/K variants remain in production today. Their maximum power at take-off ranges from 479-shp to 730-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. The Arrius 2B2 Plus is an enhanced version introduced in 2014 to power the EC 135 T3 helicopter.
