Embodiment 1

[0114] Figure 1 to Figure 3 Shown is an embodiment of the aircraft provided by the present invention. Among them, the lift body 1300 adopts an integral wing-body fusion design, and a cabin 1301 may be provided on the lift body 1300, and the cabin 1301 may be used for carrying people and / or loads. Taking the flight direction F as a reference, the lift fan system 1100 is located in front of the lift body 1300. The propulsion system 1200 is located at the tail of the lift body 1300. The lift fan system 1100 includes a plurality of lift fans 1101, and the lift fans 1101 are mainly located on a lifting body. The propulsion system 1200 includes two propulsion unit groups. The two propulsion unit groups are respectively a first propulsion unit group 1202 and a second propulsion unit group 1203 arranged on both sides of the midline of the tail of the aircraft's lift body. Each propulsion unit group includes multiple Independent propulsion unit 1201. figure 1 There are a total of 14...

Abstract

The invention discloses a short-distance or vertical take-off and landing aircraft which mainly comprises a lifting body, a lifting fan system and a propelling system, wherein the lifting fan system and the propelling system form a distribution type power system. According to the lifting fan system, force in a vertical and / or horizontal direction can be provided, and the size and / or the directionof the force can be adjusted; according to the propelling system, force in the vertical and / or horizontal direction can be also provided, and the size and / or the direction of the force can also be adjusted. When the aircraft takes off or lands down, lifting force is mainly provided by the fan system and / or the propelling system. Along with increase of the speed of the aircraft, the lifting force provided by the lifting body is increased, and the lifting force provided by the lifting fan system and the propelling system is reduced. At a horizontal flying state, the inlet and the outlet of the lifting fan can be closed, then the flying resistance can be reduced, and the lifting force can be increased. The aircraft has the advantages that requirements of the aircraft on take-off and landing fields can be lowered, the aircraft is high in horizontal flying efficiency, and the aircraft is good in controllability and reliability.

Description

Technical field [0001] The invention belongs to an aircraft, in particular to an aircraft capable of short-distance or vertical take-off and landing. Background technique [0002] Traditional fixed-wing aircraft are characterized by fast flight speed and large flight radius. This feature perfectly matches the needs of personnel and cargo transportation. However, most fixed-wing aircraft require long runways for taxiing, and cannot be used for short / vertical take-off and landing and hovering in the air. [0003] The design of using single or multiple rotors is one of the commonly used technologies for vertical take-off and landing of aircraft, such as helicopters and quad-rotors. This type of aircraft usually still needs to rely on the rotor to provide most of the lift after taking off, the flight energy is large, and the speed, volume and load are limited. [0004] There is a kind of aircraft by changing the attitude of the rotor, similar to a helicopter during take-off and landing...
