  2. Powered lift - Wikipedia

    en.wikipedia.org/wiki/Powered_lift

    As the aircraft gains speed, the rotors progressively rotate or tilt forward, with the rotors eventually becoming perpendicular to the fuselage of the aircraft, similar to a propeller. In this mode, the wing provides the lift and the rotor provides thrust. The wing's greater efficiency helps the tiltrotor achieve higher speeds than helicopters.

  3. Lifting body - Wikipedia

    en.wikipedia.org/wiki/Lifting_body

    US X-24A, M2-F3 and HL-10 lifting bodies. A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift.In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing.

  4. Compression lift - Wikipedia

    en.wikipedia.org/wiki/Compression_lift

    The area referred as the "pancake" provided compression lift in flight. In aerodynamics, compression lift refers to the increased pressure under an aircraft that uses shock waves generated by its own supersonic flight to generate lift. This can lead to dramatic improvements in lift for supersonic/hypersonic aircraft.

  5. Flight control surfaces - Wikipedia

    en.wikipedia.org/wiki/Flight_control_surfaces

    Flaps raise the maximum lift coefficient of the aircraft and therefore reduce its stalling speed. [5] They are used during low speed, high angle of attack flight including take-off and descent for landing. Some aircraft are equipped with "flaperons", which are more commonly called "inboard ailerons" [citation needed]. These devices function ...

  6. Vortex lift - Wikipedia

    en.wikipedia.org/wiki/Vortex_lift

    Vortex lift provides high lift with increasing AoA at landing speeds and in manoeuvring flight. A high AoA needed to meet landing requirements has, in the past, restricted pilot visibility and led to design complications to accommodate a drooping nose, as in the case of the Fairey Delta 2 and Concorde.

  7. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    Lift is proportional to the density of the air and approximately proportional to the square of the flow speed. Lift also depends on the size of the wing, being generally proportional to the wing's area projected in the lift direction. In calculations it is convenient to quantify lift in terms of a lift coefficient based on these factors.

  8. Stabilizer (aeronautics) - Wikipedia

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

    An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, [1] [2] that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable ...

  9. 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 ...
