The Arrius 2K1 and 2K2 was FAA-certified in November 2001. They offer 40% more power than the first version of the family, while keeping the same overall structure with only two modules for easier maintenance : a reduction gearbox module and a gas generator module which comprises a gas generator turbine with single crystal blades.
The Arrius 2K1/2K2 family is controlled by an Electronic Engine Control Unit (E.E.C.U.) which ensures automatic starting, overtemperature/overtorque/surge/flame-out protection, training mode operation and engine life management functions. The Arrius 2K1/2K2 family has a TBO of 3,000 hours.
The Arrius 2K1 powers the twin-engine Agusta A109 E Power. The A109 E Power performs in medevac (EMS), police work, VIP transport, aerial work, offshore transport, and search and rescue roles.
The Arrius 2K2 powers the twin-engine Agusta A 109 LUH (Light Utility Helicopter) ordered by South Africa Air Force (SAAF), Malaisia and Sweden. The A 109 LUH performs in medevac, surveillance, rescue and troop-carrier military roles.
