context_page_description: The Rolls-Royce/Snecma Olympus 593 was an Anglo-French afterburning turbojet which powered the supersonic airliner Concorde. It was initially a joint project between Bristol Siddeley Engines Limited and Snecma. It was based on the Bristol Siddeley Olympus 22R engine. Rolls-Royce Limited acquired BSEL in 1966 during development of the engine making BSEL the Bristol Engine Division of Rolls-Royce.
  Until regular commercial flights by Concorde ceased, the Olympus turbojet was unique in aviation as the only afterburning turbojet powering a commercial aircraft.
  The overall thermal efficiency of the engine in supersonic cruising flight was about 43%, which at the time was the highest figure recorded for any normal thermodynamic machine.
