Rolls-Royce Olympus variants (original) (raw)

The Rolls-Royce Olympus turbojet engine was developed extensively throughout its production run, the many variants can be described as belonging to four main groups. Initial non-afterburning variants were designed and produced by Bristol Aero Engines and Bristol Siddeley (BSEL) and powered the Avro Vulcan. These engines were further developed by Rolls-Royce Limited. The American Curtiss-Wright company tested a license-developed version known as the J67 and a turboprop designated TJ-38 Zephyr. Neither design was produced.
