Abstract: As one of the main propulsion devices in aerospace field, solid rocket motors have been widely used as boosters of launch vehicles, space motors, escape and separation motors for thirty years.It has been indicated that the reliability of the solid rocket motors is comparable or superior to the liquid rocket engines, while their cost is lower than the latter. These advantages continuously exsist and further develop in the next generation of the space transportation system.The developing history, the application background and the future of the foreign solid rocket motors used in space are discussed in this paper.
