uelAR74-1025 unmanNed aerial vehicle Engine
The UEL AR74-1025 UAV(Unmanned Aerial Vehicle) engine is one of a series of engines designed and manufactured by UAV Engines Ltd of Britain and based on the Wankel rotary type. The rotary engine format possess the required characteristics for UAV use with high power to weight ratio, small cross section dimensions with fuel consumption only slightly higher than comparable piston engines and low vibration values.
Development of the Wankel engine types for motor cycle application began in 1969 when BSA Motorcycles commenced this work under license. Norton Motorcycles took over from BSA in 1976 and continued the development until their demise in the early 1990s, after which several British companies continued the Wankel rotary technology development. UAV Engines Ltd continued the Norton line of development that led to the long life AR741 series for use in UAV surveilance drones.
