The Napier Eland was a British turboshaft or turboprop gas-turbine engine built by Napier & Son in the early 1950s. Production of the Eland ceased in 1961 when the Napier company was taken over by Rolls-Royce.[1]

Design and development

The Eland was first tested in 1953 in a Vickers Varsity aircraft[2]. Further flight proving was carried out from 1955 using the first production Airspeed Ambassador 2.[3] The Eland was dropped from production when Napiers was acquired by Rolls-Royce Limited in 1961[2].

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[2](later converted to Allison T-56 propjets after a number of engine failures), and the Fairey Rotodyne gyroplane. In the Rotodyne, the Eland provided the power for the tractor propellors for forward flight and acted as a gas generator to feed the rotor tipjets for vertical flight[4].
