<正>重复使用是航天运输系统的未来发展方向,是实现安全、可靠、快速、自由、低成本进出空间的有效途径。当前,垂直起降、重复使用方案渐趋成熟,“猎鹰”9火箭已经实现常态化的回收复用,“超重-星舰”或将借此实现全箭复用,美俄欧日等国家和地区的主力火箭也都瞄准采用垂直起降方案实现重复使用。在航天飞机实现升力式火箭动力重复使用方案突破和相关技术基础的积淀后,近年来轨道级和亚轨道级重复使用运载器持续取得进展,2022年X-37B和“追梦者”等轨道飞行器均有所突破,美国商业公司也在推进亚轨道级的研制。 相似文献

Solid-propellant and liquid-propellant launch vehicles have their own characteristics, both playing an important role in space transportation systems of space powers. This paper reviews and summarizes the development history of solid-propellant launch vehicles, and analyzes their technical characteristics including multiple stages, large payloads, complex separation, diverse operation modes, fast response, and mission adaptability as well as unique advantages in launch activities. This paper analyzes and proposes four development laws for solid-propellant launch vehicles, including improving comprehensive performance, infusing heritage with innovation, unitization and seriation, and optimizing power systems. Finally, this paper proposes the opportunities and challenges faced by solid-propellant launch vehicles based on market demands. 相似文献
