Ground recovery platform capable of repeatedly using carrier rocket

Abstract

The invention relates to a reusable ground recovery platform for a carrier rocket. The reusable ground recovery platform comprises a movable chassis, a capturing device and a recovery buffer device, the mobile chassis comprises a chassis framework, omni-directional driving wheels and a chassis control system, the at least three sets of capturing devices are arranged in a nonlinear mode, each capturing device comprises a recycling embracing arm, a first telescopic power piece, a capturing clamping table and a capturing control system, and the recycling buffering device comprises an oil gas buffer and a buffering energy storage control system. And the oil gas buffer is mounted in the recovery holding arm and is controlled by the buffer energy storage control system. The soft landing method has the following predictable technical effects that soft landing of the reusable carrier rocket can be achieved, a landing buffer system does not need to be installed on the reusable carrier rocket, the invalid load when the rocket takes off is reduced, and the complexity and cost of a rocket system are reduced.

Description

technical field [0001] This application relates to the technical field of reusable launch vehicle recovery, in particular to a ground recovery platform for reusable launch vehicles. Background technique [0002] At present, most of the recovery schemes for reusable liquid rockets adopt the scheme of installing buffer recovery legs on the rocket. During flight, the recovery legs are folded and stored in the rocket body structure of the rocket recovery sub-stage. Before landing, recovery The outriggers are opened in advance to provide a support and buffer for the smooth landing of the rocket, and the kinetic energy and potential energy are absorbed through the buffers on the outriggers. [0003] In view of the related technologies mentioned above, the inventor believes that there are the following defects: the launch vehicle achieves recovery through the buffer outrigger, and the structural part and control part of the recovery outrigger need to be integrated into the rocket r...

AI Technical Summary

Problems solved by technology

[0004] This application provides a ground recovery platform for reusable launch vehicles to improve the following technical problems: the solution for the recovery of the launch vehicle through the buffer legs, the structural parts and control parts of the recovery legs need to be integrated into the rocket recovery sub- stage, thus increasing the ineffective weight of the rocket recovery sub-stage, which will reduce the payload of the launch vehicle; moreover, the recovery outrigger and its control system are more complicated, even if a large number of composite materials are used to develop, the weight parameter is also large, and the same Reduced rocket payload
