Ball-borne suspended launching system based on combined unmanned aerial vehicle

Abstract

The invention discloses a ball-borne suspended launching system based on a combined unmanned aerial vehicle, the ball-borne suspended launching system comprises the combined unmanned aerial vehicle provided with a flight control system; a high-altitude balloon connected with the combined unmanned aerial vehicle through a rope; and a rope cutter fixed to the back of the combined unmanned aerial vehicle, wherein the rope is connected to the rope cutter; the combined unmanned aerial vehicle rises to a preset height through buoyancy of the high-altitude balloon and then enters a cruising state. When the balloon and the combined unmanned aerial vehicle lift off to a preset height, the rope cutter is remotely controlled to cut off the rope to separate the balloon from the unmanned aerial vehicle, so that the throwing of the combined unmanned aerial vehicle is completed, and the energy consumed by the common combined unmanned aerial vehicle during ground skating or catapult-assisted take-offis saved.

Description

technical field [0001] The invention relates to the technical field of aircraft control, in particular to a ball-mounted suspension launch system based on a combined unmanned aerial vehicle. Background technique [0002] The combined flexible UAV is a structurally innovative unmanned aerial vehicle, which can take into account the large aspect ratio, high lift-to-drag ratio, long endurance and small cluster of high-altitude and long-endurance UAVs by switching the flight state of combination and separation. The advantages of low cost, high mobility, flexible structure, and distributed deployment of UAVs. In addition, it is hopeful to solve the problems of high-altitude, long-endurance, high-aspect-ratio UAVs, large flexibility, easy tremors, and aerodynamic failure, as well as solve the shortcomings of cluster UAVs with low ceiling and short range. In terms of aerodynamic design, this configuration of UAV can greatly increase the aspect ratio of the aircraft, greatly reduce...

AI Technical Summary

Problems solved by technology

[0003] For this kind of combined UAV, its cruising altitude is relatively high, and the aircraft will fly for a long time under low-altitude non-rated operating conditions by rolling or ejecting from the ground, and it needs to consume more energy for take-off and climb, so it is significantly To reduce the endurance of the aircraft, it is a more appropriate take-off method to directly hoist the aircraft to the working height by using the ball-borne method, but it is necessary to develop a special ball-mounted hanging launch technology for the characteristics of the combined UAV.
