Abstract: In this study, taking China’s Smart Dragon 3 solid launch vehicle, which made its first successful offshore launch on December 9, 2022, as an example, we focus on the technical characteristics and key technologies of various solid motors used for the launch vehicle. The current technological development status is introduced, and the key technologies needed for large solid motors are summarized. For comparison, we also list and analyze the technical characteristics of world-class P80 and P120C solid motors used in ESA’s Vega series of launch vehicles. On this basis, the development trends of large solid motors based on the requirements for launch vehicles is proposed, providing a reference for the development of large solid motor technology for future launch vehicles in China.
