The Rolls-Royce Avon was the first axial flow jet engine designed and produced by Rolls-Royce. Introduced in 1950, the engine went on to become one of their most successful post-World War II engine designs. It was used in a wide variety of aircraft, both military and civilian, as well as versions for stationary and maritime power.
An English Electric Canberra powered by two Avons made the first un-refuelled non-stop transatlantic flight by a jet, and a BOAC de Havilland Comet 4 powered by four Avons made the first scheduled transatlantic crossing by a jet airliner.
Production of the Avon aero engine version ended after 24 years in 1974. Production of the Avon derived industrial version, currently produced by Siemens, continues to this day.
The current version of the Avon, the Avon 200, is an industrial gas generator that is rated at 21–22,000 shp. As of 2011, 1,200 Industrial Avons have been sold, and the type has established a 60,000,000 hour record for its class.
