Cod-end structure for recovering marine returning capsule in terrible ocean environment

Abstract

The invention relates to the field of aerospace, in particular to a cod-end structure for recovering a marine returning capsule in a high sea state. The cod-end structure comprises a guide component and a catching component, wherein rectangular peak is tied with a balance-weight guide ring (8) respectively at the periphery of a guide net which has a silk screen structure, and the balance weight guide rings are tied with a guide rope (18) respectively; the mouth part of the string bag-shaped cod-end (20) has a plurality of metal rings (19), a plurality of guide ropes (18) are uniformly distributed and pass through the metal rings (19) at corresponding positions, a lifting rope (22) passes through the metal rings (19) in turn, one end of the lifting rope (22) is shaped as a rope loop and connected with a shackle (22a), while the other end penetrates outside from a round hole of the shackle (22a), and the central position of the outer back part of the cad-end (20) is connected with a tail traction rope (21). The cod-end structure for recovering the returning capsule in a high sea state can implement a two-step salvage method, so the returning capsule (G) can be easily caught and recovered under the relative shaking condition; and a target can be exactly seized by the guide component and easily and smoothly caught and covered by the catching component, so the returning capsule (G) can be recovered and lifted reliably.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a corresponding appliance structure for recovering a sea return capsule floating under high sea conditions. Background technique [0002] Space rescue is a high-tech intensive field, and a lot of science and technology are condensed in every link from the launch of the spacecraft to the recovery of the return capsule. [0003] The first 900 seconds of rocket launch is the dangerous stage of the spacecraft. Once there is a problem, the astronauts will escape through the escape system; Salvage at sea. During the launch or return of the spacecraft, it is responsible for searching and salvaging the return capsule that has been splashed and dropped on the sea, receiving the voice communication of the astronauts, and conducting voice communication with the astronauts according to the requirements of the astronauts, rescuing the astronauts, taking care of the recovery of the return capsule, and r...

AI Technical Summary

Problems solved by technology

However, the size of the bag net is relatively large, the sling at the end is relatively thick, and the overall mass is large, making it difficult for personnel to control and operate

The above rescue methods will be challenged. It is difficult for the salvage ship to approach the return cabin, and it is difficult to salvage the return cabin. Rescuers carry light hanging equipment, and it is difficult to descend to the top of the return cabin through the lifting cable, and it is impossible to carry out the hoisting operation, which seriously endangers astronaut safety
