Problems solved by technology

However, it is actually very difficult to change the axis of the power system. The power requirement is very high, which will consume a lot of energy, and the structure of the power system needs to be redesigned so that it can meet the requirements of steering, which is difficult to achieve. Larger, unable to meet the needs of mass production and promotion of consumer-grade aircraft

Embodiment 1

[0038] Such as Figure 1 to Figure 4 As shown, the aircraft in this embodiment is a rotorcraft. Of course, other types of aircraft can also be used, but it must be an aircraft with multiple power systems. The rotorcraft of the present invention comprises a fuselage 1 with feet on the bottom of the fuselage 1, and an outwardly protruding machine arm 2 is installed on the fuselage 1. The number of machine arms 2 is at least three, and they are installed on the fuselage 1 symmetrically with respect to the vertical plane where the central axis of the fuselage 1 is located. Machine arm 2 has four in the present embodiment, and they are perpendicular to each other, and interval angle is 90 degree installations.

[0039] A motion control system 3 is installed at the end of the machine arm 2 . A power system 4 is installed above the motion control system 3 . In this embodiment, a propeller is installed above the power system 4, and the propeller is driven by the power system 4 to ...

Embodiment 2

[0052] Such as Figure 9 , Figure 10 , Figure 11 As shown, in this embodiment, the deflector system is a combination of a deflector and a cylinder, including a cylinder 10 connected to the end of the machine arm 2, and two upper and lower brackets 11 are installed in the cylinder 10, and the power system 4 Installed between the upper and lower brackets 11. The motion control system includes two rotating shafts 12 arranged in a cross shape, and the ends of the two rotating shafts 12 are respectively installed in the cylinder body 10 through bearings, and can rotate under control. The flow guide system also includes four blades 13, which are respectively installed on four branches of the rotating shaft 12 arranged in a cross. Therefore, the orientation of the blades 13 can be changed by controlling the rotation of the rotating shaft 12 . The function of the cylinder 10 in this embodiment is to make the jet flow more concentrated and reduce the loss rate.

Abstract

The invention discloses a multi-engine aircraft of which the motion based on controlling the direction of jet flows. The multi-engine aircraft comprises a fuselage and a power system, a flow guiding system, a motion control system, a posture sensor, a flight control system and a computer mounted on the fuselage, wherein the power system remains unchanged relative to the orientation of the fuselage and generates the vertically downward jet flows; the computer controls the output power of the jet flows generated by the power system through the flight control system to maintain the balance of the fuselage; the flow guiding system is mounted in the direction of the jet flows generated by the power system and is adjustable relative to the orientation of the fuselage; and the computer or a human controls the orientation of the flow guiding system through the motion control system to guide the direction of the jet flows generated by the power system to control the movement and steering of the aircraft. The multi-engine aircraft realizes the flight posture change of the aircraft through the cooperation between the output of the jet flows generated by the power system and the tilting of the flow guiding system. The direction of the power system remains unchanged during the flight, and the fuselage can always be level. The multi-engine aircraft is simple in structure, flexible to control and suitable for practical application.

Description

technical field [0001] The invention relates to an aircraft, in particular to a multi-engine aircraft based on controlling jet flow direction movement. Background technique [0002] The steering method of traditional aircraft is realized by changing the output power of the power system so that lift or torque is formed between the power systems. During this period, the flight control system needs to carry out precise calculations, which is not efficient, and it is difficult to cope with complex and changeable flight environments in real time. A more serious problem is that the fuselage of the aircraft will be tilted, which is not conducive to carrying video equipment and manned control on the aircraft. [0003] At present, there are some more advanced aircraft design schemes. By changing the axis of each power system to make the aircraft hover, translate, turn left, and turn right, the fuselage of the aircraft can always be kept level during the flight process, which overcom...
