The engine was designed for the Hughes AH-64 Apache and Sikorsky UH-60 Blackhawk, competing with the General Electric T700 and the Pratt & Whitney Canada PW100.The partners shared the £100 million development costs equally, Rolls-Royce made the turbines, the combustor, and the inlet particle separator while Turbomeca produced the axial-centrifugal compressor and intake.
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 ...
In aviation, propeller synchronization is a mechanism that automatically synchronizes all propellers of a multi-engine, propeller-driven aircraft so that they rotate at the same speed. Propeller synchronization serves mainly to increase the comfort of crew and passengers, since its primary purpose is to reduce the “beats” generated by ...
Distributed propulsion on an aircraft is typically characterised not only by the distributed nature of the propulsive thrust but also by utilisation of the effect this has on the aircraft aerodynamics. [2] The propulsive air flows are distributed over the aerodynamic surfaces of the craft, typically spanwise over a fixed wing.
Motorjet research was nearly abandoned at the end of World War II, as the turbojet was a more practical solution to jet power, using the jet exhaust to drive a gas turbine and providing the power to drive the compressor without the additional weight and complexity of a piston engine that generated no thrust. One of the primary advantages of the ...
Certain aircraft, like the German Bf 109 and the Macchi C.202/205 were fitted with "ejector-type exhausts". These exhausts converted some of the waste energy of the (internal combustion) engines exhaust-flow into a small amount of forward thrust by accelerating the hot gasses in a rearward direction to a speed greater than that of the aircraft.
English: The Power for Flight is a survey of NASA’s work in aircraft propulsion from its origins as the National Advisory Committee for Aeronautics (NACA) to the early 21st century. It introduces NASA’s role in the technology while taking into account economic, political, and cultural dimensions.
A tiltjet is an aircraft propulsion configuration that was historically tested for proposed vertical take-off and landing (VTOL)-capable fighters. [ 1 ] The tiltjet arrangement is, in concept, broadly similar to that of the tiltrotor ; whereas a tiltrotor utilises pivotable rotors, the tiltjet employs jet engines capable of moving to angle ...
