The aircraft starts from a vertical flight, lifting the aircraft to a high altitude. Then, the aircraft begins to glide, with the total lift less than the weight. With the aid of the forward thrust acceleration, the aircraft quickly gains speed to the aerodynamic speed and then changes the angle of attack to 15° to start an aerodynamic flight.
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes .
Hopper, a prototype test vehicle for the SpaceX Starship; Hopper balloon, a kind of ultralight hot air balloon; Hopper barge, a kind of barge; Hopper car, a type of railway freight car; Gravity wagon, or slant wagon, a type of wagon that is essentially a hopper; used in agriculture; Space hopper, a toy: a ball with handles for bouncing on
Vertical and/or short take-off and landing (V/STOL) aircraft that are able to take off or land vertically or on short runways. Vertical takeoff and landing includes craft that do not require runways at all. Generally, a V/STOL aircraft needs to be able to hover; helicopters are not typically considered under the V/STOL classification.
Lockheed NF-104A, 56-0756, zoom climbing with rocket power. A zoom climb or an unrestricted climb is a maneuver in which the rate of climb is greater than the maximum climb rate using only the thrust of the aircraft's engines.
The Ling-Temco-Vought (LTV) XC-142 is a tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. An XC-142A first flew conventionally on 29 September 1964, [ 4 ] and completed its first transitional flight on 11 January 1965 by taking off vertically, changing ...
By contrast the autogyro (or gyroplane) and gyrodyne have a free-spinning rotor for all or part of the flight envelope, relying on a separate thrust system to propel the craft forwards, so that the airflow sets the rotor spinning to provide lift. The compound helicopter also has a separate thrust system, but continues to supply power to the ...
For sub-orbital spaceflights covering a horizontal distance the maximum speed and required delta-v are in between those of a vertical flight and a LEO. The maximum speed at the lower ends of the trajectory are now composed of a horizontal and a vertical component. The higher the horizontal distance covered, the greater the horizontal speed will ...
