Rolls-Royce Olympus 593

The Olympus is a high-powered axial-flow turbojet, originally developed at Bristol Aero Engines, later passed to Bristol Siddeley, and finally to Rolls-Royce. The original design was used as the primary powerplant for the Avro Vulcan V Bomber. It was later developed for sustained supersonic performance as part of the TSR-2 program, and when this was cancelled found itself as the main powerplant for the Concorde. The basic mechanicals are still in production for industrial and naval power. Rolls Royce Olympus Engine This work is copyrighted. ... Rolls Royce Olympus Engine This work is copyrighted. ...

Bristol Siddeley Olympus (Vulcan)

The Olympus was first run in 1950 reaching 10,000 lbf (44 kN) thrust and was flying in an English Electric Canberra testbed by 1953. Entering full production in 1955, the Olympus continued to be developed by Bristol Siddeley. The Olympus 201 entered service on the Avro Vulcan in 1956. English Electric Canberra B.2. ...

By modifications to the LP compressor (which included adding an extra LP stage) and the LP turbine, it was possible to increase the thrust from the 17,000 lbf (76 kN) of the Olympus 201 to 20,000 lbf (89 kN). The new engine was known as the Olympus 301 in service use. Due to the increased air mass, the Vulcan's air intakes had to be widened and, because of the extra compressor stage, the engines were larger and would not fit into the engine bays without extensive modifications

A marine version of the Olympus was trialled in the refitted Royal Navy frigate HMS Exmouth which became the first major warship in a western navy to be powered by gas turbine engines.

Rolls-Royce/Snecma Olympus 593 (Concorde)

The Olympus turbojet is unique in commercial aviation as the only afterburning turbojet to power a commercial aircraft, Concorde. The Olympus 593 project was started in 1964, using the Avro Vulcan’s Olympus 320 as a basis for development. Bristol Siddeley of the UK and Snecma Moteurs of France were to share the project. Acquiring Bristol Siddeley in 1966, Rolls-Royce continued as the British partner. The early stages validated the basic design concept but many studies were required to achieve desired specifications, e.g. The Aérospatiale-BAC Concorde supersonic transport (SST) was one of only two models of supersonic passenger airliners to have seen commercial service. ... The Bristol Aeroplane Company (formerly British and Colonial Aeroplane Company) began building primitive Bristol Boxkites in a former tram shed and became famous for the production of the war-time Blenhein and Beaufighter, the Brabazon airliner prototypes, the Britannia and Freighter and the Belvedere and Sycamore helicopters. ...

Rolls-Royce carried out the development of the original Bristol Siddeley Olympus and engine accessories, while Snecma had responsibility for variable engine inlet system, the exhaust nozzle/thrust reverser, the afterburner and the noise attenuation system. Britain was to have a larger share in production of the Olympus 593 as France had a larger share in fuselage production.

The method by which a jet engine operates is explained more fully elsewhere, but essentially a jet draws air in at the front and compresses it. The air then combines with fuel and the engine burns the resulting mixture. The combustion greatly increases the volume of the gases which are then exhausted out of the rear of the engine. The Olympus engine takes this gas jet and passes it through straightening vanes - to obtain a laminar flow. This gas jet then enters the afterburning jet pipe where a ring of fuel injectors spray fuel onto the gases. The resulting combustion greatly improves thrust. The afterburning section was longer than the engine itself (as was the case with all early turbojets) but the thrust of the Olympus 302 rose to 30,610 lbf (136 kN). A Pratt and Whitney turbofan engine for the F-15 Eagle is tested at Robins Air Force Base, Georgia, USA. The tunnel behind the engine muffles noise and allows exhaust to escape. ... laminar and turbulent water flow over the hull of a submarine In fluid dynamics, laminar flow is a flow regime characterized by high momentum diffusion, low momentum convection, and pressure and velocity independence from time. ...

The variable geometry exhaust nozzle is two "eyelids" which vary their position in the exhaust flow dependent on the flight regime, for example when fully closed (into the exhaust flow) they act as thrust reversers, aiding deceleration from landing to taxi speed.

The variable engine inlet system was vital to the Olympus 593 on Concorde as supersonic airflow at the engine face would create shockwaves that would lead to engine surge and failure. The intake features variable ramps which alter the intake area which slows the intake air from supersonic to subsonic speed. This is achieved by positioning the ramps such that shockwaves are created at the inlet, air passing through these shockwaves is slowed. The inlet air is further decelerated as the intake area increases closer to the engine (speed of air flow decreases as area increases.) Any excess air is expelled through doors on the underside of the nacelle and some intake air bypassed around the engine and mixed with the exhaust - to increase thrust and keep the engine cool.

The word Nacelle is derived from the Old French nacele, which means a small boat or dinghy, and was in turn derived from the Latin navicella. ...

In June 1966 a complete Olympus 593 engine and variable geometry exhaust assembly was first run at Melun-Villaroche, Île-de-France, France. At Bristol, flight tests began using a RAF Vulcan bomber with the engine attached to its underside. Due to the Vulcan's aerodynamic limitations the tests were limited to a speed of Mach 0.98 (1,200 km/h). During these tests the 593 achieved 35,190 lbf (157 kN) thrust, which exceeded the requirements of the engine.
