Short-distance takeoff and vertical landing aircraft

Abstract

To create an aircraft capable of short takeoffs or vertical landings. [Solution] [Short-distance takeoff and landing aircraft] To enable short-distance takeoffs and landings, it is necessary to generate a sufficiently large amount of lift at a low aircraft speed. Since the velocity of the exhaust airflow immediately after the engine that generates thrust is much higher than the aircraft speed, the wings that directly receive it can generate a large amount of lift regardless of the aircraft speed. Furthermore, the lift is proportional to the area of ​​the wings 5. The separation plate 3 that separates the main body 1 and the landing gear 2 used in this invention also functions as a wing, so it can generate a large amount of lift regardless of the aircraft speed. [Vertical takeoff and landing aircraft] To create an aircraft capable of vertical takeoff and landing at zero speed, one can construct a composite aircraft by stacking the aforementioned short takeoff and landing aircraft vertically and in opposite directions. By providing a landing gear separator between the landing gear section and the composite aircraft section, and upper and lower separators between the upper and lower aircraft sections, these separators will generate a large amount of lift regardless of the aircraft's speed.

Description

Technical Field

[0001] The present invention relates to an aircraft capable of taking off and landing by short-distance taxiing, and further to an aircraft capable of vertical takeoff and landing and mid-air hovering.

Background Art

[0002] To prevent aircraft accidents caused by overruns on runways, aircraft capable of taking off and landing in short-distance taxiing are demanded. Furthermore, for future transportation means and emergency assistance in the event of a major disaster, aircraft capable of vertical takeoff and landing and mid-air hovering without taxiing are demanded.
