| Abstract: | To predict the mechanical performance of solid propellant grain in the full-scale motor under environment loads in life period,a sub-scale motor based on the design criterions proposed by Thepenier,was developed to evaluate the mechanical performance of grain.The design validation of the sub-scale motor was also evaluated.In particular,the digital speckle correlation method was adopted to measure the strain of the grain in the sub-scale motor under heat loads.The results show that the measurement in the sub... |
