    en.wikipedia.org/wiki/Ground_effect_(aerodynamics)

    During takeoff, ground effect can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. [2] For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At ...

    The following is a list of WIGE or 'wing-in-ground'-effect craft, also referred to as water-skimming wingships or, in Russia, 'ekranoplans'. An A-90 Orlyonok , a Soviet-era ground-effect plane Australia

    Ekranoplan A-90 Orlyonok. A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (Russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water.

  5. Ground loop (aviation) - Wikipedia

    A Focke-Wulf Fw 190 A-8 replica in a ground loop caused by a failure of the right-hand wheel brake. The right main undercarriage is collapsing. In aviation, a ground loop is a rapid rotation of a fixed-wing aircraft in the horizontal plane while on the ground.

    [4] [7] It also looked at and discarded a fast oceangoing ship and a sea-based ground effect vehicle. [1] A plan view of a ground effect concept airplane. [8] Many features of this concept were incorporated into the Boeing Pelican ULTRA. Boeing Phantom Works then selected a land-based ground effect vehicle with high drooping wings as its solution.

  7. Aircraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Aircraft_flight_dynamics

    An aircraft is streamlined from nose to tail to reduce drag making it advantageous to keep the sideslip angle near zero, though an aircraft may be deliberately "sideslipped" to increase drag and descent rate during landing, to keep aircraft heading same as runway heading during cross-wind landings and during flight with asymmetric power.

    Ground effect (cars), an effect that creates downforce, primarily in racing cars; Ground-effect vehicle, a vehicle which attains level flight near the surface of the Earth due to ground effect; Ground-effect train, an alternative to a magnetic levitation train, using ground effect in aircraft to prevent the vehicle from making contact with the ...

    DARPA launched the project in mid-2022, wanting a plane that could lift large, heavy loads by skimming the water in ground effect, and capable of operating at mid-altitudes of up to 10,000 feet (3,000 m). Utilizing the ground effect, flying at an altitude equal to 5% of the wingspan can deliver 2.3 times more efficient flight performance.
