Problems solved by technology

In the prior art, the 10N thruster power supply module of branch A in the satellite propulsion system only supplies power to the 10N thruster drive module and 10N thruster module of branch A, and the 10N thruster power supply of branch B is only the 10N thruster drive module and the 10N thruster drive module of branch B. The 10N thruster module supplies power. When the A branch or B branch 10N thruster power supply module fails, the corresponding 10N thruster drive module and 10N thruster module of the A branch or B branch will fail completely, and one branch of the satellite propulsion system Loss of function of the 10N thruster

Embodiment Construction

[0016] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0017] In the overall design of the propulsion system, there are two branches with completely independent functions, A and B. Among them, the A branch is composed of one power supply module, n thruster drive modules and n thruster modules, and the B branch is also composed of one power supply module and n thruster modules. The thruster drive module is composed of n thruster modules. The power module, thruster drive module and thruster module of branches A and B are completely independent. When the above-mentioned modules of branches A and B have double faults of different types, and the faults are not in the same branch, the propulsion system reorganization function can be used to reset A and B. Each module of the B branch is reorganized to form a new branch with complete functions for work.

Abstract

The invention discloses a restructurable satellite propulsion system, which is used for carrying out detection on modules (with failures) of the propulsion system under the condition that independent-branch components of the propulsion system have failures, closing the modules with failures, and selecting normal modules for restructuring the propulsion system, thereby realizing the functional restruction of the propulsion system.

Description

technical field [0001] The invention relates to a reconfigurable satellite propulsion system. Background technique [0002] During the development of the BD-2 satellite propulsion circuit box product, since there are two completely independent functional branches, A and B, in the overall design of the propulsion system, when a double fault occurs in the propulsion system, and the fault happens to be in the two branches, in order to To ensure that the satellite propulsion subsystem can work normally, the recombination function of the propulsion subsystem can be realized by executing the fault remote control switching command, which further improves the ability to countermeasure the failure of the propulsion subsystem. [0003] The failure modes of the satellite propulsion subsystem include the failure of the 10N thruster power supply module, the failure of the 10N thruster drive module and the failure of the 10N thruster module. In the prior art, the 10N thruster power suppl...
