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(later converted to Allison T-56 propjets after a number of engine failures), and the Fairey Rotodynegyrodyne. In the Rotodyne, the Eland powered the tractor propellors for forward flight and a compressor, via a clutch and shaft arrangement, to feed the rotor tip-jets with compressed air for vertical flight.
