Abstract

The invention provides a vertical-takeoff auxiliary system for a fixed-wing aircraft. The vertical-takeoff auxiliary system comprises a multi-shaft rotor-wing aircraft and a fixed-wing aircraft. A plurality of throwing devices are installed in the middle of the fuselage bottom of the multi-shaft rotor-wing aircraft, and a plurality of hanging parts are installed in the fuselage middle of the fixed-wing aircraft; the hanging parts are connected with the throwing devices in a hung mode, and the fixed-wing aircraft is hung below the multi-shaft rotor-wing aircraft accordingly; the multi-shaft rotor-wing aircraft carries the fixed-wing aircraft to vertically take off to the preset height and the preset speed, then the throwing devices release the hanging parts, and the fixed-wing aircraft is separated from the multi-shaft rotor-wing aircraft to autonomously fly. By means of the vertical-takeoff auxiliary system in the mode, vertical takeoff of the fixed-wing aircraft can be achieved under the condition that an existing fixed-wing aircraft does not need to be greatly modified.

Description

technical field

[0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a vertical take-off auxiliary system for a fixed-wing aircraft. Background technique

[0002] The fixed-wing aircraft utilizes the pressure difference generated on the upper and lower surfaces of the wings to obtain lift when it flies fast, and takes off against gravity. Therefore, it must reach the take-off speed before it takes off. Fixed-wing aircraft have long range, fast speed, and low fuel consumption. Once they lose power, they still have a chance to reduce the speed of descent by gliding to reduce crash losses. However, the disadvantage of fixed-wing aircraft is that it needs a very long runway to take off.

[0003] Thus, people began to study the take-off assist device of fixed-wing aircraft. For example, the fixed-wing aircraft is launched in the air by the helicopter carrier, but the disadvantages of this method are mainly: 1) the pylons of the helic...
