下一代主力运载火箭发展思考

Reflections on the Development of Next Generation Main Launch Vehicle

针对我国下一代主力运载火箭后续发展问题,首先回顾了世界主要航天国家和地区运载火箭发展历程,分析了当前我国运载火箭发展问题,基于运载火箭自身代际发展技术规律和外部发展需求两方面,构建了运载火箭发射效能公式,据此提出了我国下一代主力运载火箭4个重点发展方向,最后给出了发展目标和建议。

For Chinese next generation main launch vehicle subsequent development problem,this paper first reviews the development process of major aerospace countries launch vehicles in the world,analyzes the current development problems of Chinese launch vehicle,constructs the launch vehicle launch efficiency model based on two aspects of launch vehicle own inter-generational development technology and external development needs,puts forward four key development directions of Chinese next generation main launch vehicles.Finally development goals and suggestions are given.
