Some rotary wing aircraft are designed to stop the rotor for forward flight so that it then acts as a fixed wing. For vertical flight and hovering it spins to act as a rotary wing or rotor, and for forward flight at speed it stops to act as a fixed wing providing some or all of the lift required. Additional fixed wings may also be provided to ...
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 Magnus effect. Flettner rotor: a smooth cylindrical Magnus rotor with disc end plates.
Hafner Rotabuggy (also known as "Malcolm Rotaplane" and "M.L. 10/42 Flying Jeep") - rotary wing glider attachment for landing jeeps. Tested in 1944 but introduction of vehicle-carrying gliders led to cancellation of project. Hafner Rotachute - one-man rotor-kite for landing assault troops. Not adopted but used instead for testing in support of ...
Most unpowered rotary-wing aircraft are kites rather than gliders, i.e. they are usually towed behind a car or boat rather than being capable of free flight. These are known as rotor kites. However rotary-winged gliders, 'gyrogliders', were investigated that could descend like an autogyro, using the lift from rotors to reduce the vertical speed ...
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 forward thrust that keeps the rotor ...
The ASH 26 is an 18 metre Class glider, built of modern fibre reinforced composites. It first flew in 1993. It is manufactured by Alexander Schleicher GmbH & Co. The 'H' indicates this is a design of Martin Heide. The ASH 26 has plain flaps, a retractable undercarriage and a water ballast system.
The A-7 was the first rotary-wing aircraft designed for combat, [23] armed with one 7.62×54mmR PV-1 machine gun, a pair of Degtyaryov machine guns, and six RS-82 rockets or four FAB-100 bombs. World War II
Aircraft flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft.An aeroplane (airplane in US usage), is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".
