Vertical take-off and landing jet aircraft

Abstract

The invention discloses a vertical take-off and landing jet aircraft, which comprises a front jet apparatus, a cab, an air intake duct, a compressor, a passenger-cargo cabin, main wings, an empennage and an oil tank, five sets of jet devices are provided at the tail part, and are uniformly distributed at the center and periphery of the tail part. The front jet apparatus injects air so that the aircraft is perpendicular to the ground, the jet devices at the tail part inject air downwardly, and thereby the aircraft takes off. Four jet devices at the tail part are adjusted while flying to realize various turning of the aircraft. Three sets of jet devices at the tail part stop air injection, left and right sets of jet devices and the front jet apparatus inject air downwardly for hovering. The procedure of landing and hovering is same, but the air injection amount is reduced.

Description

technical field [0001] The invention relates to a vertical take-off and landing jet aircraft, belonging to the field of aviation technology. Background technique [0002] At present, the take-off and landing of jet aircraft mainly rely on the runway to assist the flight, and there are also a few that propose vertical take-off and landing, such as the jet helicopter with the patent application number: 200710050694.X, which combines the superior performance of modern jet aircraft with supersonic flight and direct The ease of taking off and landing is perfectly concentrated in jet helicopters. The wing and engine of the jet helicopter are movably installed and can be rotatably adjusted. During the take-off and landing process of the aircraft, the hydraulic control device is used to rotate the wing (3) and rotate the engine (2) at the same time. Changes can change the way the aircraft takes off and lands. Another way is to install the engine on the body, and use the hydraulic ...

Problems solved by technology

Using this method to change the direction of the jet port of the aircraft, although the aircraft can take off and land vertically, whether it is rotating the wing with the engine or directly rotating the engine, a large amount of kinetic energy will be consumed, and the stability of the aircraft will be greatly reduced at the same time

[0003] The F-35 aircraft of Lockheed Martin Corporation of the United States rotates the direction of the nozzle of the aircraft to spray downward when taking off, so that a high-pressure air cushion is formed at the bottom of the entire aircraft, and the aircraft is slowly lifted up. Although this method can realize the vertical take-off of the aircraft However, it takes a lot of air to form a high-pressure air cushion at the bottom, and the aircraft rises slowly
