垂直起降运载火箭总体方案研究

垂直起降运载火箭研制是航天与航空技术的一次融合,相对于传统一次性火箭而言,其研制是对运载火箭总体设计理念的革新。本文从运载火箭总体设计的角度出发,结合工程研制实际,通过垂直起降火箭一二级分离、推进剂管理、气动设计、弹道优化设计等方面的风险评估及约束条件分析,结合具体方案设计,对垂直起降火箭与传统火箭总体设计的差异及难点进行了分析,给出了建议,同时阐述了对垂直起降运载火箭总体设计的思考。常规运载火箭成熟的设计理论和技术,需要增加新的约束和进行改进后才可适用于垂直起降火箭方案设计。

General Design Study of Vertical Takeoff and Landing Launch Vetical

The development of vertical take-off and landing launch vehicle is a fusion of aerospace and aviation technology. Compared with the traditional expendable launch vehicle, its development is an innovation of the general design concept of launch vehicle. Combined the actual project development, this article from the perspective of the general design of the launch vehicle, research the secondary stage separation, propellant management ,aerodynamics design, the ballistic optimization design of risk assessment and analysis of constraints of the vertical take-off and landing rockets. The differences and difficulties of general design between vertical take-off and landing launch vehicles and traditional launch vehicle are analyzed. At the same time, this paper considers the general design of the vertical take-off and landing vehicle and gives suggestions. Conventional rocket mature design theory and technology need to increase new constraints and improvement, so that they can be applied to design vertical take-off and landing launch vehicle.
