高超声速吸气式推进系统是高超声速技术的关键，许多国家都先行安排进行研制，并且将研制重点放在具有自加速和巡航能力（即能在很宽Ｍａ范围运行）的双模态冲压发动机和起飞助推用的引射火箭低速发动机方面。经过了４０多年的艰难发展，美俄等国目前已经从地面试验进入飞行试验阶段。文中概述这种高超声速吸气式推进组合发动机的工作原理、国外发展动向和应用前景。 Hypersonic Aspirated propulsion systems are the key to hypersonic technology, with many countries prioritizing development and focusing on dual-mode ramjet engines with self-accelerating and cruising capabilities (ie, capable of operating over a wide range of Ma) And take-off booster rocket low-speed engine. After more than 40 years of difficult development, the United States and Russia have now entered the flight test phase from ground tests. This paper summarizes the working principle of this hypersonic aspirated propulsion combined engine, the development trend of foreign countries and application prospects.
