| Abstract: | The grain cracks of solid rocket motor were repaired by means of grouting repair technique.Mechanical properties,energy characteristics and burning capability of the repaired grain were tested,and the grain burning-area regression law of the repaired region and the internal ballistic properties of the repaired SRM were simulated.The structural integrity of the motor and repaired propellant grain was analyzed.The test and simulation results show that the grouting repair technique is effective. |
