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. Chine (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Chine_(aeronautics)

   The chine lift increases with the square of the Mach number, helping counterbalance the rearward shift in the lift of the main wing in supersonic conditions. If a tailless (Delta) wing is trimmed for safe subsonic flight, at high speeds it gains excess trim drag in pitch and becomes excessively stable resulting in poor manoeuvrability.

4. Doppelmayr USA - Wikipedia

   The former Doppelmayr CTEC logo as seen on a lift. Doppelmayr USA, Inc is an aerial lift manufacturer based in Salt Lake City, Utah, [1] and a subsidiary of the worldwide Doppelmayr Garaventa Group. The United States company was formed in 2002 after the merger of Garaventa of Goldau, Switzerland, and Doppelmayr of Wolfurt, Austria. [2]

5. Forward-swept wing - Wikipedia

   en.wikipedia.org/wiki/Forward-swept_wing

   One of the drawbacks of forward swept wings is the increased chance of divergence, an aeroelastic consequence of the lift force on forward swept wings twisting the tip upwards under increased lift. On a forward-swept design, this causes a positive feedback loop that increases the angle of incidence at the tip, increasing lift and inducing ...

6. Tiltrotor - Wikipedia

   en.wikipedia.org/wiki/Tiltrotor

   In this mode the rotors provide thrust as a propeller, and the airfoil of the fixed wings takes over providing the lift via the forward motion of the entire aircraft. Since the rotors can be configured to be more efficient for propulsion (e.g. with root-tip twist) and it avoids a helicopter's issues of retreating blade stall , the tiltrotor can ...

7. Detachable chairlift - Wikipedia

   en.wikipedia.org/wiki/Detachable_chairlift

   A detachable chairlift or high-speed chairlift is a type of passenger aerial lift, which, like a fixed-grip chairlift, consists of numerous chairs attached to a constantly moving wire rope (called a haul rope) that is strung between two (or more) terminals over intermediate towers. In contrast to the fixed-grip version, the chairs of a ...
