摘　　要：空射运载火箭具有“高效、灵活、快速和廉价”的优点,引起各国的关注。空射运载火箭动力系统通常采用固体、液体、固液组合或冲压发动机等,与其他动力形式相比,固体空射运载火箭具有更“快速”和更“灵活”等优势。但在设计中也面临着诸多关键问题,如结构和重量强约束下设计问题、宽温域环境适应性问题、复杂力学环境适应性问题、高可靠吊挂技术问题和高安全性问题等。首先介绍空射运载火箭的典型动力系统方案,然后重点围绕固体火箭发动机面临的关键问题展开了论述和分析,并探讨解决相关问题的研究方向,最后给出相关建议。The air⁃launch rocket has some advantages,such as high efficiency,flexibility,rapidity and low cost,which has at⁃tracted the attention of all countries.The propulsion system of air⁃launch rocket usually adopts solid rocket motor,liquid rocket en⁃gine,solid⁃liquid hybrid motor or ramjet.Compared with other power forms,air⁃launch rocket has the faster and more flexible advan⁃tages.However,there exists also many key problems in the design,such as the design problem under strong constraints of structural and weight,the adaptability under wide temperature range environments,the adaptability under complex mechanical environments,the high reliability technology of suspend structure and the high security problems.Firstly,the power system scheme of typical air⁃launched carrier rocket was introduced.Then,the key problems for solid rocket motors were systematically analyzed,and the research direction of solving related problems were discussed.Finally the relevant suggestions were provided.
