Low-impact clamp band joint unlocking device

Abstract

The invention relates to a low-impact clamp band joint unlocking device. When two bands respectively encircle to form semi-circumferences, first ends of the two bands are correspondingly connected by a separating firework element, and second ends of the bands are correspondingly connected by another separating firework element; a plurality of clamp blocks are uniformly distributed on the inner side of a circumference at intervals, the two bands encircle to form the circumference, sufficient pre-tightening force is exerted to the bands by screwing up the separating firework elements, so that the bands can be clamped on the periphery of a butt-joint frame of a satellite and a rocket, and V-shaped surfaces of the clamp blocks are simultaneously meshed with the butt-joint frame of the satellite and the rocket, so that the satellite and the rocket are reliably connected; and the two bands can be unlocked and separated from each other by detonating at least one of the separating firework elements to break the separating firework element. The low-impact clamp band joint unlocking device has the advantages that impact force generated when the satellite is separated from the rocket can be reduced on the premise of reliable connection of the satellite and the rocket, and influence of separation impact to the satellite is reduced.

Description

technical field [0001] The invention relates to a star-rocket connection unlocking device for a launch vehicle, in particular to a low-impact Ф937 belt connection unlocking device applicable to launch vehicles such as China Aerospace CZ-2 and CZ-4. Background technique [0002] The star-rocket connection unlocking device is an important part of payload carriers such as launch vehicles and upper stages. The commonly used star-rocket connection unlocking device at home and abroad is a belt connection unlocking device. Based on the advantages of reliability and high connection stiffness, the belt connection unlock The device has been widely used in domestic and foreign aerospace fields, and is currently the preferred connection and unlocking method for domestic and foreign spacecraft. [0003] Conventional strap connection release see figure 1 , figure 2 , image 3 As shown, it usually consists of a strip 100, a clamp block 200, a separation pyrotechnic element 300 (general...

AI Technical Summary

Problems solved by technology

[0006] With the development of satellite technology, higher requirements are put forward for the separation impact of the satellite and rocket. The traditional structure of the belt-type satellite-rocket connection unlocking device has a large impact on the separation attitude of the satellite and the sensitive equipment and pipelines on the satellite. Serious, but inconsistent with the low-impact requirements proposed by today's satellite development trends, affecting the development of satellite technology
