Description

technical field [0001] The invention relates to a landing anti-turnover device for an airdrop system. Background technique [0002] The landing of the airdrop system is greatly affected by changes in environmental factors. Changes in the wind field, the terrain and height of the airdrop site, and changes in the center of gravity of the equipment all interfere with the landing state of the airdrop system; The mismatch will cause the airdrop system to overturn when it lands, which will limit the use of the airdrop system. [0003] The airdrop system currently adopts passive anti-roll stabilization technology, including anti-roll bracket stabilization technology and directional anti-roll stabilization technology. Among them, the anti-turnover bracket stabilization technology adopts the anti-turnover bracket structure to install and fix on the cargo platform, and widen the width of the side of the cargo platform when landing to prevent the cargo platform from rolling over. The...

AI Technical Summary

Problems solved by technology

The anti-roll bracket (or anti-flap plate) increases the weight of the system itself and increases the risk of paracord hooking, and if the anti-roll bracket (or anti-flap plate) is accidentally deployed in the cabin ahead of time, it will cause serious flight accidents. Anti-turnover support (or anti-turnover plate) has high reliability requirements

[0005] The landing of the airdrop system is greatly affected by changes in environmental factors. Changes in the wind field, the terrain and height of the airdrop site, and changes in the center of gravity of the equipment all interfere with the landing state of the airdrop system; The mismatch will cause the airdrop system to overturn when it lands, resulting in certain limitations in the use of the airdrop system

[0006] The directional anti-rollover device uses components such as ground anchors and directional anti-rollover connecting ropes. During the deployment and stabilization of the airdrop system, the directional anti-rollover device is opened, and the ground anchors and connecting ropes connected to the long axis of the equipment tail are thrown to the ground. After landing, grasp the ground and tighten the connecting rope under the action of the wind, and rotate the equipment to land in the direction of the wind. When the wind is small, the connecting rope is not pulled tightly, so the stabilization effect cannot be achieved; at the same time, the rotating state of the equipment cannot be sensed, and the released connecting rope is When tightening, the bottom edge of the rotating equipment may also be hooked, causing the ground anchor to not necessarily pull the equipment along the long axis of the equipment to rotate, causing the long axis of the equipment to be nearly perpendicular to the flight direction when landing, and the equipment topple over

[0007] Anti-rolling bracket stabilization technology and directional anti-rolling stabilization technology have certain limitations and cannot adapt to airdrop systems in complex environments
