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 ...
Lift fan is an aircraft configuration in which lifting fans are located in large holes in an otherwise conventional fixed wing [1] or fuselage. It is used for V/STOL operation. The aircraft takes off using the fans to provide lift, then transitions to fixed-wing lift in forward flight.
The J85 and lift-fan combination was a precursor to developments which led to the first GE high BPR engine, the TF-39. [4] The lift fans were driven by turbine blades mounted around the periphery of the fan, with mass flow 13 times greater than the gas generators mass flow and increased thrust 3 times over that available using a propelling nozzle.
The Bell V-280 Valor is a tiltrotor aircraft being developed by Bell Helicopter for the United States Army's Future Vertical Lift (FVL) program. [2] The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas.
A vertical-lift bridge or just lift bridge is a type of movable bridge in which a span rises vertically while remaining parallel with the deck. The vertical lift offers several benefits over other movable bridges such as the bascule and swing-span bridges. Generally speaking, they cost less to build for longer moveable spans. [1]
The purpose of inclined elevators is to provide accessibility to steep hillsides and inclines at minimal effort to the user. An inclined elevator is a form of cable railway . Users with mobility and disability challenges often use an incline platform lift to climb staircases in their home with their mobility scooter or motorized wheelchair .
Pont Gustave-Flaubert – crossing the Seine at Rouen, this lift bridge is the highest vertical-lift bridge in Europe, [citation needed] allowing ships up to 55 m tall to pass under it. It is 670 m long, with a span of 116 metres [3]. A striking design feature, the two road sections are mounted outside the central towers.
