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.
 Design and development
The Eland was first tested in 1953 in a Vickers Varsity aircraft. Further flight proving was carried out from 1955 using the first production Airspeed Ambassador 2. The Eland was dropped from production when Napiers was acquired by Rolls-Royce Limited in 1961.
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 Rotodyne gyroplane. 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.
 Engines on display
A turboshaft Eland is on display at the The Helicopter Museum, Weston-super-Mare.
