一种简便易用的运载火箭设计实践方法

An Easy-to-Use Design Practice Method for Launch Vehicle

运载火箭设计是一项充满挑战的工作,运载火箭的设计实践一直是运载火箭设计专业学习的难题,传统的内容以理论学习为主,缺乏适合学生学习的火箭设计方法。文中提出了一种方便学习实践的运载火箭设计方法,详细介绍了设计流程,通过弹道分析绘制了方便使用的设计曲线,给出了简便易用的火箭总质量估算曲线。通过计算实例验证了该方法的可行性,为运载火箭设计学习的实践环节提供了有力的支持,文中方法也同样适用于工程设计。

Design for the launch vehicle is a challenging task;the design practice is a very difficult issue in the course teaching.The traditional training content is focused on the basic theory,which lacks the rocket design method suitable for the undergraduate students.For that reason,a simple and convenient design method for the launch vehicle is proposed in this paper;and the design flow chart is introduced in detail.The ballistic analysis curves and overall quality curve are drawn as useful diagram tool for designing.Finally,it is shown through a design example that the method this paper proposed is feasible,and it can also be used in engineering practice.
