System for retracting fixed-wing unmanned aerial vehicle (UAV) through pneumatic capture net

Abstract

The invention belongs to the technical field of aircraft intelligent control and discloses a system for retracting a fixed-wing unmanned aerial vehicle (UAV) through a pneumatic capture net. The system comprises a capture net support component supported by a support surface, and the pneumatic capture net supported by the capture net support component. The pneumatic capture net comprises a group of inflation pipes which are in a deflated and inflated state and are supported by the support surface. The group of inflation flexible pipes is arranged in rows. Each inflation pipe is provided with a first end and a second end. The first ends of the flexible pipes are positioned by facing the support surface. The second ends of the flexible pipes are connected mutually by a top connector tube. According to the invention, the fixed-wing UAV is retracted through the flexible pneumatic capture net, and the problems that the fixed-wing UAV is inapplicable to the urban and rural areas, the requirement for operation of the UAV is too high, thereby causing a low retraction success rate of the UAV, and the stress damage to the fuselage is easily caused due to the single rigid net structure are solved.

Description

technical field [0001] The invention belongs to the technical field of aircraft intelligent control, and in particular relates to an aerodynamic capture net recovery system for a fixed-wing unmanned aircraft. Background technique [0002] Currently, fixed-wing unmanned aerial vehicles (UAVs) are widely used in environmental protection, forestry, agriculture, commercial and military purposes, including natural resource and wildlife management, soil erosion and environmental change monitoring, fire detection and damage assessment, agricultural vegetation health monitoring , Fleet, road and life and property safety protection monitoring and patrol, communication relay, etc. [0003] An important issue in the use of fixed-wing unmanned aerial vehicles (UAVs) is how to successfully recover them after use without damage. my country's urban roads are not suitable as recovery runways for fixed-wing unmanned aerial vehicles (UAVs) due to safety issues, and the road grades in rural a...

AI Technical Summary

Problems solved by technology

[0004] In summary, the existing problems in the prior art are: the existing unmanned aerial vehicle recovery system is not applicable to fixed-wing unmanned aerial vehicles (UAV); if CN201620740788.4 adopts the traditional parachute method, it is not applicable to urban and rural areas ; Such as CN201620740740.3 adopts the form of hook / lanyard to reclaim, which is too high for the control of unmanned aerial vehicles, which will easily cause low recovery success rate; such as CN201520937722.X, which is only applicable to military fixed-wing unmanned aerial vehicles (UAV ), its single rigid net structure is easy to cause stress damage to the fuselage during recovery
