Design method for detonation control of pyrotechnic device for separation of spacecraft compartment

Abstract

The invention relates to a design method for detonation control of a pyrotechnic device for separation of a spacecraft cabin, comprising the steps of: a. designing a detonation control circuit for a pyrotechnic device for separation of a spacecraft cabin; b. based on the control circuit in the step a, Design redundant control circuits. According to the detonation control design method of the pyrotechnic device used for the separation of spacecraft compartments of the present invention, it has high safety and can effectively prevent false detonation of pyrotechnic devices; at the same time, the entire power supply channel and control circuit adopt derating design and double redundancy design, which is reliable With high reliability, it can complete the compartment separation function under a single failure, which can effectively ensure the smooth completion of the main mission of the spacecraft.

Description

technical field [0001] The invention relates to the field of aerospace electrics, in particular to a design method for detonation control of a pyrotechnic device used for compartment separation of a spacecraft. Background technique [0002] With the increasingly complex requirements of spacecraft flight missions, large and complex spacecraft often adopt multi-cabin design, and each cabin performs different functions. , with the increasing demand for on-orbit services in the future, the compartment separation design is also one of the basic technologies to realize the functional reconfiguration of on-orbit vehicles. [0003] Module separation is a key task in the spacecraft's on-orbit mission, which is related to the success or failure of the mission. Generally, a reliable redundant design for the whole process and the whole path should be carried out to ensure the success of the mission. The compartment separation of spacecraft in orbit is mostly achieved by detonating pyro...
