| Abstract: | The vacuum performance of the solid rocket motors can not be transformed from data of ground firing test with big expansion ration nozzle directly.Based on the model of interior ballistics property, the performance relation between the ground and the vacuum is analyzed, and a transforming method of performance from ground to vaccum has been got. At last, the results calculated are compared with the experimental results. |
