【摘要】 概要介绍了我国第一种整体式固体火箭冲压发动机试验研究样机的研制，讨论了样机地面试验研究和飞行试验研究两大阶段中，整机（含主级和助推级）、各部件及分系统的设计、试制和试验工作。样机结构合理，主级比冲比国外同类型号导弹发动机有较大提高，助推级综合性能和热防护技术也优于后者。更多还原

【Abstract】 An integral solid rocket ramjet engine in China is introduced.The design,manufacture and test of the whole engine(both sustainer and booster),components and sub systems during ground and flight test phases were described.The test results show that this prototype was reasonable,the specific impulse of cruise stage was higher than that similar to engines abroad,and the integrated booster performance and thermal protection technique were satisfactory更多还原
