摘　　要：重型运载火箭发展的核心问题是总体构型方案,包括箭体直径、发动机选型及技术继承性问题。通过对国外重型运载火箭发展脉络进行分析,研究其发展特点,总结了发展趋势,即重型运载火箭由传统的串联构型向捆绑助推器构型发展;重型运载火箭采用大直径箭体和大推力发动机;充分发挥液体、固体发动机的优势,实现最佳动力组合,并充分利用成熟技术。最后,提出我国重型运载火箭总体设计工作的相关建议。The key problem of heavy-lift launch vehicle development is to define its overall configuration scheme, including stage diameter and engine types, as well as the technical inheriting. The development of heavy-lift launch vehicles of foreign coun- tries were analyzed while the characters and trends were summarized. That is the configuration adopts booster configuration besides traditional serial stage combination, adopts large-diameter stages and high-thrust engines, adopts the optimal power combination with merits of both liquid and solid engines and adopts the mature technologies. Finally, the corresponding suggestions were given to the design of heavy-lift launch vehicles in China.
