| Abstract: | A lot of experiments on the mechanical properties of the HTPB grain of solid rocket motor was conducted.The aging law of its mechanical properties was obtained,and load state acted on the grain in production,transportation,storage,handle,ignition and burning procedures was analysed.According to the most critical load,the stress and stain that were in various aging were computed by FEM.Comparing the mechanical properties of grain in various aging,the service life of the grain was predicted |
| Keywords: | Solid propellant rocket engine Propellant grain Propellant storage Storage life Finite element method Mechanical test |
