  2. Ice protection system - Wikipedia

    en.wikipedia.org/wiki/Ice_protection_system

    In aeronautics, ice protection systems keep atmospheric moisture from accumulating on aircraft surfaces, such as wings, propellers, rotor blades, engine intakes, and environmental control intakes. [1] Ice buildup can change the shape of airfoils and flight control surfaces, degrading control and handling characteristics as well as performance.

  3. Rotor wing - Wikipedia

    en.wikipedia.org/wiki/Rotor_wing

    The various types of such rotor wings may be classified according to the axis of the rotor. Types include: [1] [2] Vertical-axis. Conventional rotary wings as used by modern rotorcraft. Spanwise horizontal-axis. Wing rotor: an airfoil-section horizontal-axis rotor which creates the primary lift. Magnus rotor: a rotor which creates lift via the ...

  4. Rotorcraft - Wikipedia

    en.wikipedia.org/wiki/Rotorcraft

    The later canard rotor/wing (CRW) concept added a "canard" foreplane as well as a conventional tailplane, offloading the rotor wing and providing control during forward flight. For vertical and low-speed flight, the main airfoil is tip-driven as a helicopter's rotor by exhaust from a jet engine , and there is no need for a tail rotor .

  5. Rotor kite - Wikipedia

    en.wikipedia.org/wiki/Rotor_kite

    A Focke-Achgelis Fa 330 rotor kite. A rotor kite or gyrokite is an unpowered, rotary-wing aircraft. Like an autogyro or helicopter, it relies on lift created by one or more sets of rotors in order to fly. Unlike a helicopter, gyrokites and rotor kites do not have an engine powering their rotors, but while an autogyro has an engine providing ...

  7. Adaptive compliant wing - Wikipedia

    en.wikipedia.org/wiki/Adaptive_Compliant_Wing

    An adaptive compliant wing is a wing which is flexible enough for aspects of its shape to be changed in flight. [ 1 ] [ 2 ] Flexible wings have a number of benefits. Conventional flight control mechanisms operate using hinges, resulting in disruptions to the airflow, vortices, and in some cases, separation of the airflow.

  8. Glider (aircraft) - Wikipedia

    en.wikipedia.org/wiki/Glider_(aircraft)

    A paraglider is a free-flying, foot-launched aircraft. The pilot sits in a harness suspended below a fabric wing. Unlike a hang glider whose wings have frames, the form of a paraglider wing is formed by the pressure of air entering vents or cells in the front of the wing. This is known as a ram-air wing (similar to the smaller parachute design).
