Re-entry capsule device

Abstract

The invention relates to the technical field of manned spacecrafts, in particular to a re-entry capsule device. The re-entry capsule capsule device comprises a capsule body, wherein an installation blind hole is formed in the bottom face of the capsule body, a containing blind hole is formed in the side wall of the installation blind hole, a first sliding groove is formed in the side wall of the installation blind hole, and a second sliding groove is formed in the side wall of the containing blind hole; an anti-impact column body inserted into the installation blind hole, wherein the lower end of the anti-impact column body abuts against an anti-heat insulation cover, the side wall of the upper end of the anti-impact column body is provided with a first protruding block, and the lower end of the first sliding groove is provided with a first limiting block; a blocking column body inserted into the containing blind hole, a spring is pressed between one end of the blocking column body and the end wall of the containing blind hole, a second convex block is arranged on the side wall of the end, and a second limiting block suitable for blocking the second convex block is arranged at the end of the second sliding groove. According to the re-entry capsule device provided by the invention, the anti-impact column body can resist the impact force borne by the anti-impact column body under the blocking force of the blocking column body, so that the damage caused by direct collision between the capsule body and the ground is avoided, and the safety of astronauts and precise instruments is ensured.

Description

technical field [0001] The invention relates to the technical field of manned spacecraft, in particular to a return capsule device. Background technique [0002] Generally, a manned spacecraft can be divided into three parts: the propulsion module, the orbit module and the return module. Among them, the return module is also called the cockpit. It is the "cab" of the astronauts. After the return module and the propulsion module are separated, the return module returns, the propulsion module is burned, and the orbit module is equivalent to an earth observation satellite or a space laboratory, and it will continue to work in orbit for a period of time. [0003] The return cabin generally includes a cabin body, a heat shield and an airbag. The cabin body is generally set in the shape of a tumbler (that is, the shape formed by replacing the bottom surface of the circular table with a spherical surface) to maintain stability during the return process. There is a reverse thrust i...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the cabin body is prone to collision when the return capsule hard lands, causing damage to the astronauts or precision instruments in the capsule, thereby providing a return capsule capable of resisting impact device
