Embodiment Construction

[0014] In order to understand the present invention more clearly, the present invention will be described in further detail below: the structure of the synchronous transmitting device designed by the present invention is as follows figure 2 , 3 , 4, including igniter 1, detonator 2, main piston 3, guide pin 4, sealing ring 5, four sub-piston sleeves 6, four sub-pistons 7, shear pin 8, main piston guide sleeve Barrel 9, connecting rod 10 and base 11, igniter 1 and detonator 2 are installed in the base 11 of synchronous launching device, before synchronous launching device works, the part with bigger area of ​​main piston 3 is arranged in the base 11 and is positioned at detonation. Above the device 2, the smaller part of the main piston 3 is set in the main piston guide sleeve 9, and a tapered shoulder transition is adopted between the larger part and the smaller part of the main piston 2, and the guide pin 4 is set The main piston guide sleeve 9 is used to limit the movement...

Abstract

The invention discloses a spatial flying net synchronous launching device which comprises an igniter, an exploder, a main piston, a guide pin, a seal ring, four auxiliary piston sleeves, four auxiliary pistons, a shearing pin, a main piston guide sleeve and connecting rods. The four auxiliary pistons are pushed by the main piston, in the initial stage, the main piston pushes the auxiliary pistons to cut off the shearing pin through mechanical contact, the main piston continues to move to allow the seal ring to lose sealing effect, high-pressure fuel gas directly acts on the auxiliary pistons, each auxiliary piston pushes the corresponding connecting rod and the mass block fixedly connected with the connecting rod, so that launching of multiple mass blocks is achieved, launching synchronism of the mass blocks is achieved, launching speed is increased by utilizing the high-pressure fuel gas, and high safety is achieved.

Description

technical field [0001] The invention relates to a space flying net synchronous launching device, in particular to a space flying net launching synchronous launching device, which belongs to the field of aerospace technology. Background technique [0002] With the development of space technology, it is becoming more and more important to capture non-cooperative targets such as space debris and abandoned satellites on-orbit. Among them, the flying net capture technology is a space technology that is relatively popular in international research. It mainly uses the flying net deployment mechanism to launch a large net made of thin ropes in the direction of the captured target. After wrapping the target spacecraft, it will The target spacecraft is retracted or controlled. Taking advantage of the fact that the flying net has a large interception area, which is beneficial to cover the captured target, the flying net capture technology has become a capture system with a certain fau...
