Abstract

The invention provides an electric retractable type rocket prototype supporting mechanism. The invention relates to a vertically lifting repeatable carrier landing support mechanism, in order to solveproblems that in the prior art, the support circle diameter of the landing support mechanism is smaller, the air resistance of rocket launching is too large, and first-order vibration of support connecting rods in the landing process can easily lead to the failure of recovery work. The mechanism includes a drive component and a plurality of support legs. The support legs are uniformly arranged around the bottom of a main body. The tops of the support legs are rotatably connected with and installed on the side wall of the main body, the support connecting rods of the support legs are connectedwith the support legs through buffers, the tops of the support connecting rods of the support legs and the bottoms of support connecting rods of the main body of a rocket are rotatably connected withone end of a drive connecting rod through hinge pins, the other end of the drive connecting rod is rotatably connected with a drive component, and the tops of the support connecting rods of the mainbody of the rocket are rotatably connected with the main body. The mechanism is used for the field of landing support mechanisms.

Description

technical field [0001] The invention relates to a landing support mechanism for a vertical take-off and landing repeatable carrier, in particular to an electrically retractable retractable rocket prototype support mechanism. Background technique [0002] At present, the cost of rocket launch is high. Among them, the main components of the rocket take up a large part of the launch cost, while the fuel cost of the rocket takes up a small part. Traditional rockets are no longer recycled after launch, resulting in high rocket launch costs. In order to reduce rocket launch costs, Reduce the area of ​​the rocket landing area, reduce the threat of rocket wreckage to the property of the people in the landing area, and follow the international upsurge in the development of recyclable rockets, and successfully apply vertical take-off and landing technology in the return process of recyclable rockets, and use the landing support mechanism to realize rocket recovery. The soft landing, t...
