Locking And Releasing System In Space Telescope

Space telescope locking and releasing system is one of the most important part in aerospace. It can provide the part in the spacecraft from being under attack. In this letter, the developing status and primary characteristics of several locking and releasing system in recent years were summarized. The main locking and releasing system can be part with pyrotechnic device and un-pyrotechnic device. The paper introduces the system and the way that the device released by compared the pyrotechnic and the un-pyrotechnic device. In the way of comparing the different device, the letter made the point that each of these device had its advantages that should been developed, and the disadvantages that should been improved. These analyses will provide references for the design of the locking and releasing system in the future of telescope research.
