An Entity of Type: aircraft, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

A rotor wing is a lifting rotor or wing which spins to provide aerodynamic lift. In general, a rotor may spin about an axis which is aligned substantially either vertically or side-to-side (spanwise). All three classes have been studied for use as lifting rotors and several variations have been flown on full-size aircraft, although only the vertical-axis rotary wing has become widespread on rotorcraft such as the helicopter.

dbo:abstract
  • A rotor wing is a lifting rotor or wing which spins to provide aerodynamic lift. In general, a rotor may spin about an axis which is aligned substantially either vertically or side-to-side (spanwise). All three classes have been studied for use as lifting rotors and several variations have been flown on full-size aircraft, although only the vertical-axis rotary wing has become widespread on rotorcraft such as the helicopter. Some types provide lift at zero forward airspeed, allowing for vertical takeoff and landing (VTOL), as in the helicopter. Others, especially unpowered free-spinning types, require forward airspeed in the same manner as a fixed-wing aircraft, as in the autogyro. Many can also provide forward thrust if required. (en)
  • Un'ala rotante può essere un rotore o un'ala che ruota per creare una portanza aerodinamica. Generalmente il rotore può ruotare sul suo asse allineato verticalmente al baricentro del velivolo o a rotori trasversali. Le diverse varianti hanno portato alla realizzazione di velivoli, ma solo il montaggio verticale aerogiro è diventata di uso comune come nell'elicottero. Alcuni tipi di ala rotante permettono la portanza da velocità zero rispetto alla velocità dell'aria, permettendo il decollo e l'atterraggio verticale (VTOL), come nel caso dell'elicottero. Altri, devono avere una velocità relativa rispetto all'aria come nel caso dei velivoli ad ala fissa o come nell'autogiro. (it)
