2. Rolls-Royce LiftSystem - Wikipedia

   en.wikipedia.org/wiki/Rolls-Royce_LiftSystem

   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 ...

3. Voith Schneider Propeller - Wikipedia

   en.wikipedia.org/wiki/Voith_Schneider_Propeller

   The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...

4. Aircraft flight mechanics - Wikipedia

   en.wikipedia.org/wiki/Aircraft_flight_mechanics

   In flight a powered aircraft can be considered as being acted on by four forces: lift, weight, thrust, and drag. [1] Thrust is the force generated by the engine (whether that engine be a jet engine, a propeller, or -- in exotic cases such as the X-15-- a rocket) and acts in a forward direction for the purpose of overcoming drag. [2]

5. Powered lift - Wikipedia

   en.wikipedia.org/wiki/Powered_lift

   The F-35B uses both a lift-fan and vectors engine thrust down. A lift jet is a lightweight jet engine used to provide vertical thrust for VTOL operation, and is then shut down in forward flight. Some VTOL designs, including the Soviet Yakovlev Yak-38 and Yakovlev Yak-141, have used both vectored thrust from the main engine and additional thrust ...

6. Rolls-Royce Thrust Measuring Rig - Wikipedia

   en.wikipedia.org/wiki/Rolls-Royce_Thrust...

   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 ...
