Abstract: |
The paper analyzed a certain type of control moment gyroscopes. Firstly it sorted out main failure modes, then proposed corresponding life and reliability assessment models and methods. Finally, it collected the in-orbit flight and ground test data, and evaluated the life and reliability of the control moment gyroscopes. The research improved the control moment gyroscopes’ reliability, service life and quality assurance effectively. |
