The Eland was used to power various aircraft including the Westland Westminster heavy-lift helicopter, the Canadair CL-66; a turbine-powered version of the Convair CV-340 for the Canadian military[1] and the Fairey Rotodyneconvertiplane. In the Rotodyne, the Eland provided the power for the tractor propellors for forward flight and as a gas generator to drive the main rotor for vertical flight[2].
