An integrated ejection/recovery device of a shipborne unmanned aerial vehicle

Abstract

The invention relates to an integrated ejection / recovery device of a shipborne unmanned aerial vehicle, which comprises a base, a stability augmentation device, a base seat, an ejection device and a recovery device. The base seat is mounted on the base through bearings so as to be rotatable in the circumferential direction, and a cushioning device is mounted on the bottom of the base seat for reducing the impact force. The ejection device and recovery device of the unmanned aerial vehicle (UAV) are integrated into one body, which reduces the occupying space, improves the mobility of the device, and expands the application range of the UAV take-off and landing auxiliary device. Using the rotating base structure, the unmanned aerial vehicle (UAV) ejection take-off slideway is used as rockerarm, and the impact load is converted into torque by the integral rotating motion of the slideway and the base seat and transmitted to the cushion device in the base seat, which reduces the structuralstrength requirement of the collision net recovery system for UAV, and reducing the self-weight of the UAV. Through the self-stabilizing device and the terminal guiding device, the recovery precisionof the unmanned aerial vehicle is improved, and the influence of the operating environment on the recovery precision and the operating pressure of the unmanned aerial vehicle are reduced.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle systems, and in particular relates to a carrier-borne unmanned aerial vehicle ejection / recovery integration device. Background technique [0002] The takeoff and landing of fixed-wing drones needs to rely on runways, and cannot be used on warships, islands and reefs. At present, most of the shipboard ejection and net impact recovery devices used to assist UAV takeoff and landing are independent devices, with low integration, large space occupation and poor maneuverability, which still limit the wide application of fixed-wing UAVs. In order to solve the above problems, the existing patent technology such as the Chinese invention patent application number 201410258717.6 discloses a "foldable UAV ejection and recovery device", which integrates the UAV's air pressure catapult and collision net recovery device into one device , improve the integration of ejection / recovery devices, faci...

AI Technical Summary

Problems solved by technology

Although this patent integrates the UAV's ejection take-off and net impact recovery device into a set of devices, it does not have a buffer design for the recovery device. It is necessary to strengthen the structure of the fuselage of the UAV, which limits the scope of application of the device; it does not consider the design of stability enhancement, and it is difficult for the UAV to crash into the recovery net accurately when the warship shakes greatly; the recovery device only has Telescopic pole, when recycling, it is necessary to manually hang the recycling net on the telescopic pole, and the degree of automation and intelligence is low
