The Rolls-Royce Pegasus is a British turbofan engine originally designed by Bristol Siddeley. It was manufactured by Rolls-Royce plc. The engine is not only able to power a jet aircraft forward, but also to direct thrust downwards via swivelling nozzles. [1] Lightly loaded aircraft equipped with this engine can manoeuvre like a helicopter.
Full authority analogue control was used in the 1960s and introduced as a component of the Rolls-Royce/Snecma Olympus 593 engine of the supersonic transport aircraft Concorde. [3] However, the more critical inlet control was digital on the production aircraft.
The Rolls-Royce Thrust Measuring Rig (TMR) was a VTOL aircraft developed to explore the practicality, characteristics, and requirements of such an aircraft. [2] It was widely known by its nickname of the Flying Bedstead due to its radically unconventional appearance for an aircraft, basically consisting of a rectangular tubular framework that was built around the engines, a platform being ...
The equivalent vanes on the Rolls-Royce Nene reduced the inlet losses to the extent that thrust was increased from 4,000 to 5,000 lb at the same turbine temperature. [ 103 ] Modern subsonic inlet with rounded inlet lip to prevent boundary layer separation in cross winds on the ground and high angle of attack during take-off rotation.
Combined with thrust from the LiftFan (20,000 lbf or 89.0 kN) and two roll posts (1,950 lbf or 8.67 kN each), the Rolls-Royce LiftSystem produced a total of 41,900 lbf (186 kN) of thrust. [35] This compares with the maximum thrust of 23,800 lbf (106 kN) for the Harrier's Rolls-Royce Pegasus engine.
Only thrust-vectoring stood the test of time, with the introduction of the Rolls-Royce Pegasus bypass turbofan engine having separate vectoring nozzles for the cold fan (bypass) and hot exhaust flows, which first flew in the Hawker P.1127 VTOL research aircraft of 1960.
The Rolls-Royce/MAN Turbo RB.193 is a vectored thrust turbofan engine designed and manufactured by Rolls-Royce and MAN Turbo in the mid-1960s. The engine test flew in its sole application, the VFW VAK 191B VTOL fighter aircraft but production did not follow after cancellation of the associated aircraft project.
In 1946 he was entrusted with the design of the Olympus engine, which performed flawlessly on its very first test bed run, largely as a result of the discipline that Gordon Lewis brought to its design. [See Pegasus The Heart of the Harrier, by Andrew Dow.] The Olympus was later developed to power the Avro Vulcan, TSR-2 and Concorde.
