摘要：
In order to improve the launch coefficient as the goal, a systems engineering technology is proposed. Combined with the design object, the overall multi-level design process and optimization object are sorted out from the four aspects of design concept, constraint boundary, design method, and identification return, to build the overall system of technologies. Taking the system as the traction, combined with the development practice of the new generation of launch vehicles, the research process and application effects of some of the technologies such as safety margin shooting, active environmental control, multi-disciplinary joint optimization, and propellant residue identification are summarized. At the same time, the direction of follow-up and continuous research is pointed out, which is of great significance to support the improvement of the launch coefficient. © 2023 China Spaceflight Society.
