Abstract: In this paper, the explosive problem in end-burning solid propel-lant rocket motors is discussed. The primary causes of the explosion in end-burning rocket motors is analyzed.It is experimentally indicated that when a combined charge consisting of the wood false grain and the short propellant grain is used for selecting the increase rate of initial burning surface, the experimental results will reveal an unsuitable increase rate due to large deviation.If the conclusion obtained from these experiments is used in the design of end-burning grain, the rocket motor will explode.
