Non-initiating explosive device satellite and rocket separation unlocking device

Abstract

The invention provides a non-initiating explosive device satellite and rocket separation unlocking device. The device comprises a bottom plate, a thrust mechanism, an unlocking control mechanism, multiple sets of locking mechanisms and multiple satellite connecting plates. The bottom plate is fixedly connected with the rocket; the locking mechanism and the thrust mechanism are fixed to the end face, away from the rocket, of the bottom plate. The satellite connecting plates are arranged on the faces, away from the bottom plate, of the locking mechanisms, and each satellite connecting plate is connected with one locking mechanism in a locking mode. The end face, away from the locking mechanism, of the satellite connecting plate is fixed to the bottom of the satellite, and when the rocket is separated from the satellite, the satellite connecting plate moves along with the satellite. The unlocking control mechanism is fixed on the bottom plate and is connected with the locking mechanism; the end face, away from the bottom plate, of the thrust mechanism abuts against the bottom of the satellite. The thrust mechanism is used for providing thrust for separation of the satellite and the rocket. The structure is simple and reliable, the number of parts is small, the overall rigidity is high, vibration generated when the rocket flies is not amplified, and satellite separation attitude control is good.

Description

technical field [0001] The present application relates to the technical field of satellite and rocket separation, and in particular to a non-explosive satellite and rocket separation and unlocking device. Background technique [0002] In the aerospace field, the separation of the rocket and the satellite, as the last action of the rocket launch, plays an important role in the success or failure of the rocket launch. The satellite-rocket separation device needs to keep the rocket and the satellite locked and connected during the rocket flight state; after receiving the separation command, the rocket and the satellite must be separated in time to ensure that the satellite can proceed to the next step. [0003] The commonly used separation method of pyrotechnics has a greater impact on the satellite and is easy to damage the sensitive components on the satellite. Most of the non-pyrotechnic separation devices adopt mechanical structure action to realize multi-point (more than ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the unlocking devices for non-pyrotechnic star rockets are relatively complicated, which increases the possibility of failure; moreover, there are many small parts, and the overall rigidity is poor, which is easy to cause vibration amplification during rocket flight; when releasing at multiple points at the same time, the release force is not enough. From the center of the mechanism, it is easy to produce release deviation, which makes the attitude of the satellite after separation poor, resulting in the defect of high cost of satellite attitude adjustment
