Detonation control design method of pyrotechnic device for spacecraft cabin section separation

Abstract

The invention relates to an detonation control design method of a pyrotechnic device for spacecraft cabin section separation. The method includes the following steps: a. designing an detonation control circuit of the pyrotechnic device for spacecraft cabin section separation; and b. designing a redundant control circuit based on the control circuit in the step a. According to the detonation control design method of the pyrotechnic device for the spacecraft cabin section separation, the safety is high, and the false detonation of a pyrotechnic product can be effectively prevented; and meanwhile, the whole power supply channel and control circuit adopt derating design and double redundancy design, the reliability is high, and the cabin section separation function can be completed under a single fault, and thus the successful completion of the main mission of the spacecraft can be effectively ensured.

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...
