Research on automated load testing of the drag cone retraction and deployment system in flight tests

Abstract In response to the automated load testing requirements of the drag cone retraction and deployment system in flight tests, a fuzzy tension controller based on fuzzy control theory was designed according to the system’s characteristics. A testing platform for the loading system was established to verify the system’s tension control performance. The experimental results show that the loading system outputs a stable load under both constant and variable tension control conditions, with an error within 10%.
