Rocket recycling device and liquid rocket

Abstract

The invention provides a rocket recycling device and a liquid rocket. The rocket recycling device includes at least two support structures, an arresting cable, at least two guiding mechanisms, and atleast two buffering mechanisms. the two support structures are spaced apart from each other, and the two guiding mechanisms are respectively fixedly disposed on end portions of the two support structures; and the arresting cable is used for connecting the two support structures by the two guiding mechanisms, and portions of the arresting cable on both sides of the two guiding mechanisms are respectively connected to the two buffering mechanisms. The buffering mechanisms are used for applying a pre-tightening force to the arresting cable, and after a to-be-recycled rocket is in contact with thearresting cable, buffering of an acting force applied to the to-be-recycled rocket is achieved by cooperating with expansion and contraction of the arresting cable. The rocket recycling device and the rocket of the invention capture the to-be-recycled rocket by utilizing the arresting cable, so that posture and speed requirements of rocket recycling can be reduced, and the success rate of the rocket recycling is improved.

Description

technical field [0001] The invention relates to the technical field of rocket recovery, in particular to a rocket recovery device and a liquid rocket. Background technique [0002] Rocket recovery technology is a bright pearl in the field of aerospace technology and a comprehensive manifestation of the strength of aerospace technology. Therefore, it has also received great attention from various aerospace powers. At present, there is no liquid rocket recovery scheme that has been put into use in China. SpaceX and Blue Origin of the United States have successfully recovered rockets many times. For example, the rocket recovery technology scheme adopted by Space X in its recent launches is: during the landing process of the rocket sub-stage, the main engine is ignited to achieve deceleration, and at the same time, the attitude control engine is used to adjust the flight attitude of the rocket sub-stage, so that Make sure the rocket falls in a nearly vertical attitude. When t...

AI Technical Summary

Problems solved by technology

[0004] This kind of vertical recovery technology of the rocket sub-stage has high requirements on the control of the attitude and speed of the rocket when it lands. If the attitude or speed of the rocket sub-stage is not well controlled, it is likely to cause the rocket to topple or explode, causing the rocket to fall. Recovery completely failed
