EC 635 - Light Utility Helicopter (LUH)

The EC 635 - Light Utility Helicopter (LUH) is the military version of the EC 135 and applies the same technology. It is built by the EUROCOPTER Group, owned 70% by AEROSPATIALE France and 30% by Daimler Aerospace (DASA) of Germany. The EC 635 is a light-weight twin-engined, eight seats multi - role helicopter with wide use of composite material and crashworthy designed seats and fuel system. New generation high set main rotor and shrouded tail rotor systems (Fenestron type) provide low noise and safe operation. High operational efficiency, adverse weather day / night operations, high performance with power reserve and an advanced maintenance concept are among the key features of the EC 635.

The military EC 635 is offered with two powerplant options. The FADEC controlled Turbomeca Arrius 2B1 or the Pratt & Whitney 206B engines provide fast cruising speed and long range. Utilising the aircraft's inherent multi - role capability the EC 635 is suited for military and para - military operations as utility, training, troop transport, reconnaissance and SAR. The helicopter's cabin is accessible through side sliding doors and two large rear clam-shell doors, is particularly suited for disaster relief missions and humanitarian aid.
