Rolls-Royce Bristol Pegasus, engine of the vertical takeoff Harrier, in the Bristol Industrial Museum, England. Pegasus 1 (BE53-2) The two prototype engines were demonstrator engines which developed about 9,000 lbf (40 kN) on the test bed. Neither engine was installed in a P.1127. Pegasus 2 (BE53-3) Used in the initial P.1127s, 11,500 lbf (51 kN)
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
E2 was a static test airframe, and did not ever fly. E3 was furnished with both Pegasus and RB162 lift engines installed, being intended to evaluate the design's vertical flight mode. [citation needed] The four Rolls-Royce RB162 lift engines seen from the bottom of a nacelle. The design of the Do 31 was heavily reliant upon its engine ...
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.
the rear of the F135 engine (nozzle rotated down) that powers the Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift ...
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.
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.
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 ...
