Although the rocket propulsion technologies have been used for several decades, the traditional motor can not meet the special rotating requirement. A kind of spinning solid rocket motor (SSRM) which used as power device of some kinds of dispenser was introduced. This kind of motor has the structure characterization for tangential nozzles. Its design scheme and prediction of interior ballistic performance were discussed. And the main factors should to be considered in design were analyzed comprehensively. In order to research working performance of the SSRM static test was carried out. The calculation and test results indicate that the design can satisfy general requirement of its application normally.
