Testing and Qualification of booster flex seals for S200 Solid Rocket Booster

摘要

A successful acceptance test program requires a thorough understanding of the strength and rigidity requirements of space vehicle structures, the predicted loads and environments the structure will experience during the mission and the materials and manufacturing process used. These are obtained from appropriate structural and service load analysis, evaluation of manufacturing processes and the results of design development tests. The S200 stage of LVM3 launch vehicle is a 200 Tonne class large solid rocket booster with flex nozzle system for thrust vector control. The development and qualification of the flex nozzle components required systematic evolution of the testing process to ensure the adequacy of the design for loads during the regime of flight. Every component of the flex nozzle system undergoes acceptance test programme prior to integration in the flight nozzle. This paper describes the evolution in the testing philosophy of the 200 Tonne class solid rocket booster flex seal.
