Guide net shooter for recovering marine returning capsule in high sea state

Abstract

The invention relates to the field of aerospace and in particular to a guide net shooter for recovering a marine returning capsule in a high sea state. A handle (16) is fixed on a shell (2), one side of the shell (2) extends in a way of conical dispersion to form a launching tube (9), a balance weight guide ring (8) is inserted into the launching tube (9), each weigh balance ring is tied with a guide net (10) and a guide rope (22), the roots of all launching tubes (9) are mutually communicated to form an injection chamber (12) which is communicated with the inner part of the shell (2) through a vent hole (6) formed in the centre of a front panel of the shell (2); and the axis of the shell (2) is provided with a valve core rod (5) of which the front end is pressed against the central vent hole (6) on the inner wall of the front panel of the shell (2), and a sealed gas storage chamber (15) in the shell (2) is filled with a high-pressure inertia gas; and a trigger rod (13), through a linkage mechanism, drives the valve core rod (5) to move back and forth, so the front end of the valve core rod (5) is pressed against or departs from the vent hole (6). When the guide net shooter is used, the salvage area can be increased, a target can be easily caught, and the operation and the implementation are flexible and convenient, so the salvage accuracy can be improved, and the salvage aim can be reliably fulfilled.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a corresponding device 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 returning the ...

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
