1976年在火星上放置仪器着陆器的海盗号任务包括一个空气动力减速器作为着陆序列的一部分。减速机是一种单级迫击炮盘隙带降落伞,于1965年开始为旅行者号项目开发,并在1972年为维京号任务的减速系统进行飞行资格认证时达到高潮。本文总结了研究、开发和鉴定工作。简要介绍了海盗号任务和火星大气所施加的特殊运行条件和约束,以及它们对减速系统的影响,以及由此产生的技术问题的解决方法。
The Viking mission to place an instrumented lander on Mars in 1976 includes an aerodynamic decelerator as part of the landing sequence. Development of the decelerator, a single-stage mortared disk-gap-band parachute, began in 1965 for the Voyager project and culminated in the flight qualification of the decelerator system for the Viking mission in 1972. This paper summarizes the research, development, and qualification effort. The special operating conditions and the constraints imposed by the Viking mission and the Mars atmosphere, their effects on the decelerator system, and the solution of the resulting technical problems are briefly described.
