Carrier landing mechanism and method based on oil-gas buffer and anti-crash device

Abstract

The invention discloses a carrier landing mechanism based on an oil-gas buffer and anti-crash device and a method thereof. The carrier landing mechanism includes at least three landing brackets uniformly arranged on the side wall of the carrier in the circumferential direction; the landing bracket includes an anti-crash device. device, retractable strut, oil and gas buffer device and auxiliary casing; the anti-crash device is fixed on the outer wall of the carrier, and its piston is hinged through the connecting rod and one end of the retractable strut, the other end of the retractable strut and the oil and gas buffer device One end is coaxially fixed; the auxiliary shell is triangular, two corners are hinged with the lower end of the side wall of the carrier respectively, and the other end of the other corner is hinged with the oil-gas buffer device. The invention can not only realize the repeated use of the large dead-weight carrier under normal working conditions, but also realize the safe recovery under dangerous working conditions, and at the same time realize the lightweight and compact structure.

Description

technical field [0001] The invention relates to the field of reusable carrier buffer systems, in particular to a carrier landing mechanism based on an oil-gas buffer and anti-crash device and a method thereof. Background technique [0002] More and more countries have begun to study the reusable technology of the carrier, and a reusable carrier has been born. After completing the launch mission, the carrier will decelerate and adjust its attitude under the action of the reverse thrust rocket to achieve safety. After landing conditions, use the buffer landing bracket to safely descend to the landing field. At present, the Falcon-9 series of reusable vehicles developed by SPACEX has been launched many times and achieved success. my country's reusable vehicle is still in the development stage and has not yet been put into operation. During the recovery process of the vehicle, the reliability of the landing buffer support is a necessary guarantee for its safe landing, and its ...

AI Technical Summary

Problems solved by technology

[0003] The existing reusable carrier buffer system mostly uses aluminum honeycomb crush material for energy absorption buffer, which has the advantages of light weight, high buffer energy absorption efficiency, etc., but it cannot be reused, and cannot be restored after deformation, and cannot be used for transportation. attitude self-repair

In addition, due to the accuracy of the control system and unexpected situations in the landing environment during the landing process, dangerous conditions that exceed the design state of the buffer system may occur, resulting in damage to the vehicle structure. The currently known technical solution is to use oil-honeycomb multiple Level buffer device to solve such problems

However, the multi-stage buffer is arranged on the buffer pillar, which takes up a lot of space and does not take advantage of the lightweight design of the landing bracket
