Manipulator for rocket recovery

Abstract

The invention relates to a manipulator for rocket recovery. The manipulator is mainly used for the recovery of a first rocket stage. The manipulator structurally comprises a clamp, an arm, a landing platform, a large buffering hydraulic cylinder, a small buffering cylinder, a driving hydraulic cylinder, a telescopic suspension arm beam and a telescopic type supporting leg. The telescopic type suspension arm beam is fixedly connected with the telescopic type supporting leg, the telescopic type suspension arm beam and the driving hydraulic cylinder, the driving hydraulic cylinder and the arm, the arm and the bottom platform are connected through cylindrical pins, and the large buffering hydraulic cylinder and the small buffering cylinder are located on the bottom platform. When a rocket lands, the telescopic type suspension arm beam and the telescopic type supporting leg are turned into an opened state from a retracting state, the arm is driven to opened by the driving hydraulic cylinder, when the rocket lands on the landing platform, the arm is retracted by the moving of the driving hydraulic cylinder, and the landing buffering of the rocket is achieved. The buffering performance ofthe manipulator is excellent, the safety performance is high, the structure is simple, the cost is lower, the manipulator can be recycled, and automatic correcting of the rocket when the rocket landscan be achieved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a manipulator for rocket recovery. Background technique [0002] The main purpose of studying the launch and recovery of reusable launch vehicles is to reduce launch costs. As we all know, the cost of space launch has always been high. The cost of transporting a 1kg object to the sky is about 10,000 to 20,000 US dollars, mainly because the launch vehicle is a one-time use. According to Pang Zhihao, an aerospace expert in my country, the successful recovery of the first stage of the launch vehicle can save 80% of the cost. [0003] The typical representative of overseas research on rocket recovery is the US Space Exploration Corporation (SpaceX). After four rocket recovery failures, it finally achieved a smooth landing of the recovered rocket. After the "Falcon 9" carrier rocket sent the cargo spacecraft into space, The first-stage rocket lands vertically on an offshore platf...
