Abstract

The invention provides a landing leg mechanism for recovering a rocket, the landing leg mechanism comprises an on-rocket mounting support and a plurality of landing leg devices, the on-rocket mounting support is fixed at the bottom of the rocket, and the plurality of landing leg devices are uniformly fixed on the on-rocket mounting support at intervals; the landing leg device comprises a top plate, a bottom plate, a buffer spring and a damping buffer mechanism; the top plate is fixed on the mounting support on the rocket; the top ends of the buffer springs are fixedly connected with the top plate, and the bottom ends are fixedly connected with the bottom plate; and the top end of the damping buffer mechanism is fixedly connected with the top plate and the bottom end is fixedly connected with the bottom plate. When the rocket is landed, the four landing legs make contact with the ground, the landing leg structures are compact, good buffering and damping capacity is achieved, and meanwhile the high-temperature-resistant environment is achieved.

Description

technical field [0001] The present application relates to the technical field of rocket recovery, in particular to a landing leg mechanism for rocket recovery. Background technique [0002] The landing leg of the recovery rocket is a device that acts as a shock absorber and support for the rocket device when it lands on the ground. The device is located at the bottom of the rocket, and needs to withstand the reverse impact force of the rocket when it lands. It also needs to have shock absorption and high temperature resistance. [0003] At present, the common recovery rocket landing leg device is "grasshopper leg". Contents of the invention [0004] The purpose of this application is to provide a landing leg mechanism for recovering rockets. When the rocket lands, it contacts the ground through four landing legs. The landing legs are compact in structure, have good buffering and shock absorption capabilities, and are resistant to high temperature environments. [0005] I...
