摘要：
The development of the Long March 8 (LM-8) series of launch vehicles is reviewed, which is designed to fill the gap of the payload capability of 3 to 4. 5 tons to the sun-synchronous orbits (SSO), and to derive the no-side-booster configuration covering the payload capability of less than 3 tons, thus taking the main role of the madium-lift launchers in the launch market to constitute China's next-generation of launch vehicles. On this basis, research and development of the LM-8 variants is being carried out to further improve the performance and shorten the launch period. The key technologies of the LM-8 with fundamental configurations are introduced, and the innovations of the upgraded version being developed are discussed, including the closed-loop self-pressurization for the hydrogen tank, the hydrogen and oxygen common bottom tank with a diameter of 3. 35 meter and PMI sandwiches, etc. In line with the construction of the Wenchang commercial launch site, the future development of Long March 8 series is prospected. © 2023 China Spaceflight Society.
