Westland Wessex Owners' Workshop Manual: 1958 onwards (all models) - An insight into the design, construction, operation and maintenance of an anti-submarine, trooping, SAR and WIP helicopter (Haynes Manuals) (Hardcover)
With a full and active service life of more than 40 years with the Royal Navy and the RAF, the Westland Wessex was one of the most versatile helicopters of the Cold War era. As a British-built turbine-powered development of the American Sikorsky H-34, the Westland Wessex was developed and produced under license by Westland Aircraft (later Westland Helicopters). One of the main differences from Sikorsky's H-34 was the replacement of the piston-engine power plant with a turboshaft engine. The Wessex was the first helicopter to be produced in large numbers that made use of a gas turbine engine. Early models were powered by a single Napier Gazelle engine, while later builds used a pair of Rolls-Royce Gnome engines.
