| Abstract: | The erosive burning and stagnation point drift in burning process of a solid rocket motor that has tubular charge with forge length-diameter ratio arc studied. Numerical simulation of internal now field was carried out using segmented analytiCal method in the case of the assumption of quasi-steady flow of burning product, and the stagnation point drift was calculated. |
