The proposed mode of operation was to land and take off as a tail-sitter, using the wing as a conventional rotor. The craft would then tilt over to horizontal flight and lift would be provided by cyclic pitch variation of the rotor wings, with the wing tip ramjets now angled to provide forward thrust. [5]
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 ...
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".
|rot number= – the number of main (lifting) rotors on a rotary-wing aircraft. This will only be displayed if the number is greater than 1 |rot dia= – the diameter of the main (lifting) rotor(s) on a rotary-wing aircraft |rot area= – the area of the main (lifting) rotor(s) of a rotary-wing aircraft. For multi-rotor aircraft, this is the ...
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 ...
Primary manned gliders, kited, are glider kites when being kited; when released to glide, these are not kites. Conversely, the hang-lined hang glider pilot may be kited up in his or her aircraft but when released to free-flight, such aircraft remains a gliding kite or kite glider. The Martin Glider was kited by many different means. [171]
Whereas a helicopter works by forcing the rotor blades through the air, drawing air from above, the autogyro rotor blade generates lift in the same way as a glider's wing, [8] by changing the angle of the air [6] as the air moves upward and backward relative to the rotor blade. [9]
In 2010 Aviastroitel became Glider Air Craft and production resumed. [7] [8] The aircraft is made from fibreglass. Its 12.6 m (41.3 ft) span wing employs a Wortmann FX-60-157 airfoil. The AC-4 can be fitted with a McCulloch MC-101B two-stroke engine of 12 hp (9 kW) that will sustain flight. A Ballistic Recovery Systems parachute is optional. [1 ...
