Problems solved by technology

But even if it is so advanced, compared with the same series of traditional take-off and landing F35A, F35B's range and ammunition load are still greatly reduced.
In addition, the flight control of the F35B during the take-off and landing phase is still too complicated. In addition to still needing the cooperation of the tail nozzle of the engine, it also needs to rely on multiple methane nozzles on the body to jointly control and adjust the attitude of the aircraft, which can achieve vertical take-off and landing. Control of the aircraft while hovering
With such a complex flight control system, a slight error in any part may very likely lead to a major accident involving aircraft crash and death

Embodiment 1

[0052] The present invention is a high-speed stealth fixed-wing aircraft capable of vertical take-off and landing, comprising a body 2 and wings of a fixed-wing aircraft, lift fans 1 arranged before and after the wings, thrust fans 5 arranged in the middle of the wings, and rear sections of the body A jet engine 9 is provided.

[0053] The lower part of the thrust fan 5 is provided with a downward nozzle 28 through which air is sprayed to provide upward auxiliary lift.

[0054] The thrust fan 5 is provided with a cover door 30 that can be opened and closed at the rear. By closing the cover door 30, the airflow is ejected downward to generate upward lift, or by opening the cover door 30, the air jet is sprayed backward to generate forward thrust.

[0055] The air inlet of the jet engine 9 arranged in the rear section of the body 2 communicates with the thrust fan 5 , that is, the airflow duct is separated by the thrust fan to supply air for the jet engine 9 .

[0056] The thru...

Embodiment 2

[0058] The main body of the present invention is the body 2 of a fixed-wing aircraft with a normal layout, which can be a fighter aircraft, a transport aircraft, and various civilian models. Four rotor structures are arranged around the body 2 of the present invention. The rotor structure drives the lift fan 1 to provide upward lift through four vertically arranged lift engines 14, and can provide power for forward, backward, left, and right flight and steering. This is achieved by adopting appropriate rotation directions and rotation speeds for the four lift fans. The lift engine 14 is connected with the body 2 through a strengthening strut 12 . The lift engine can refer to the technical indicators of the lift engine of the V22 "Osprey", but a single engine does not need to be so large, and it also needs to be configured as a tiltable rotor structure.

[0059] The forward and turning mode of this typical four-rotor (ie "four-axis") aircraft is realized by taking appropriate...

Embodiment 3

[0066] The present invention is a high-speed stealth fixed-wing aircraft capable of vertical take-off and landing, comprising a body 2 and wings of a fixed-wing aircraft, lift fans 1 arranged before and after the wings, thrust fans 5 arranged in the middle of the wings, and rear sections of the body A jet engine 9 is provided. The present invention does not need to rely on the airstrip in the traditional sense when taking off and landing, and only needs a small open space. When taking off, the present invention starts four lift engines 14 arranged on the front and rear sides, and simultaneously starts the thrust fan 5 arranged in the middle section of both sides and sprays air downward. Along with the present invention has produced enough lifting force, the body of the present invention just can constantly rise and realize take-off.

[0067] After the present invention realizes hovering in the air, increase the rotating speed of the two rear rotors on both sides of the body, ...

Abstract

The invention discloses a high-speed stealth fixed wing aircraft capable of vertically rising and falling. The high-speed stealth fixed wing aircraft comprises an aircraft body and side wings of a fixed wing aircraft, wherein lift fans are arranged on the front side and the rear side of each side wing, a thrust fan is arranged at the middle section of each side wing, and a jet engine is arranged at the rear section of the aircraft body. The lower portion of each thrust fan is provided with a downward nozzle, and the upward auxiliary lifting force is provided through the downward nozzles. The rear portion of each thrust fan is provided with a closed cover door, and an air inlet of the jet engine communicates with the thrust fans. According to the high-speed stealth fixed wing aircraft, themain advantages of a four-rotor aircraft, a propeller aircraft, a jet aircraft and a hovercraft are integrated, the system structure is simplified, and the reliability of the system is enhanced. The flight and steering maneuvering in the air can be realized in a plurality of modes, the system redundancy is high, and the reliability is high. According to the thrust engine, rotation and conversion in the vertical-horizontal direction do not need to be carried out, the direction of the air flow can be controlled only by controlling opening and closing of the cover door, and the system is simple and reliable in structure.

Description

technical field [0001] The invention relates to the technical field of aircraft design, in particular to the technical field of design and manufacture of multipurpose aircraft. Background technique [0002] Modern jet aircraft are becoming more and more advanced, but as fixed-wing aircraft, they have higher requirements for take-off and landing runways, and it is difficult to complete flight tasks that require short-distance take-off and landing or even vertical take-off and landing. Hover in the air. [0003] Although helicopters can solve the problem of vertical take-off and landing, thus greatly reducing the dependence on take-off and landing runways, the flying speed of traditional helicopters is very low compared with fixed-wing aircraft. Ceiling, range and load are also limited. The emergence of the type of tilt rotor aircraft represented by the American V22 "Osprey" combines the vertical take-off and landing of helicopters and fixed-wing aircraft (note: this can onl...
