1950s Swedish turbojet aircraft engine From Wikipedia, the free encyclopedia
The STAL Dovern was a Swedish turbojet design of the early 1950s, named after a lake in Finspång municipality in Östergötland, Sweden.[1] Intended to power the Saab 35 Draken, this aircraft was powered by the Rolls-Royce Avon instead. The Dovern did not enter production.

The STAL company had been designing steam turbine engines and in the 1940s begun designing gas turbine engines. Their first running engine was the Skuten, ground tested in 1949 but not flown.[2] The Dovern was the next design, featuring a nine-stage axial compressor and single-stage turbine. First run in 1951, the engine was flight tested during 1953 using an Avro Lancaster provided by Air Service Training. The engine was installed underneath in a nacelle faired-in to the Lancaster's bomb bay. After several thousand hours of ground running and more than 300 hours of flight testing the engine was not selected, the Rolls-Royce Avon being preferred.[3]
