Advances in the Analysis of Storage Failure of Solid Rocket Motor

Abstract Solid rocket motor(SRM) in the whole life cycle, to withstand temperature, gravity, vibration, ignition shock, axial overload and other loads, directly affect of engine. Based on failure mode, mechanism criteria SRM, this paper elaborates explains relevant test numerical simulation methods that storage SRM method analysis, finds under action individual or compound load, column will produce a slight lysing damage. These defects cause great interference process, have creep effect through long-term which not only damage expand inside drug column, but also lead changes shape drug, seriously affecting combustion performance mechanical The safety reliability solid motors are greatly reduced. conclusion is significance study analysis SRM.
