Flexible return capsule capable of avoiding hot melting of air bag

Abstract

The invention relates to the technical field of reentry capsules, in particular to a flexible reentry capsule capable of avoiding hot melting of an air bag. Comprising a cabin body and an air bag, at least one set of mounting grooves are formed in the outer surface of the side wall of the cabin body, clamping grooves are formed in the groove walls of the mounting grooves, each mounting groove is internally provided with a set of blocking assembly, and each blocking assembly comprises a blocking column slidably mounted in the corresponding mounting groove, and an embedding groove is formed in the side wall of each blocking column; the clamping pin is installed in the embedding groove in a sliding mode, the clamping pin can be aligned with the clamping groove through sliding of the blocking column, and the blocking column extends out of the cabin body when the clamping pin is aligned with the clamping groove; the spring is pressed between the clamping pin and the groove bottom of the embedding groove; and the driving part is located on the end face, close to the bottom of the mounting groove, of the bumping post, is suitable for driving the bumping post to slide outwards along the mounting groove and is connected with a reentry capsule control system. The flexible return capsule capable of avoiding hot melting of the air bag can prevent the air bag from being in direct contact with the capsule body, so that air leakage of the air bag due to hot melting of the capsule body is avoided.

Description

technical field [0001] The invention relates to the technical field of return capsules, in particular to a flexible return capsule that can avoid thermal fusion of airbags. Background technique [0002] The flexible return capsule includes a cylindrical cabin and an airbag at the bottom of the cabin. The airbag will open after entering the atmosphere and surround the cabin. On the one hand, it can reduce its falling speed and protect the cabin from atmospheric friction and ablation , on the other hand also mitigates damage from ground or water impacts during landing. [0003] After the existing flexible return capsule enters the atmosphere, the airbag is opened. If it encounters excessive wind resistance or other external forces, the airbag may approach the cabin body, or even touch the cabin body, causing the airbag to melt and leak, thus making the return capsule posture Tuning out of balance happens to roll over. Contents of the invention [0004] Therefore, the techn...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the airbag of the flexible return capsule in the prior art is easy to contact the thermal fusion of the cabin body and leak air, thereby providing a flexible return capsule that can avoid the thermal fusion of the airbag
