Abstract
For increasing the specific impulse of nozzleless booster, the performance of dual burning rate grain was analyzed. Taking into account the erosive burning,the numerical calculations were made for three types of the combined grain (segmented grain, fixed and variable thickness layered grain) by using one-dimensional unsteady interior ballistics model. The results show that the combined grain could reduce the peak pressure and increase the average pressure of the nozzleless booster, and improve the nozzleless booster's specific impulse and make the strength of the ramjet combustor case be better used, which will obviously improve the performance of the nozzleless booster and ramjet motor.关键词
