| Abstract: | The crack risk is analyzed. The key factors causing the crack to propagate and the calculation methods of the propellant damaged extent caused by convective burning in the crack are concluded on the basis of the many researches both inside and outside the country in this field during tens years. The main theoretical models, numerical simulation level and the test means of the crack propagation process at present are introduced and reviewed. |
