运载火箭防风减载效果快速分析方法研究

摘要

Calculational methods of ground-wind forces and moments for launch vehicle are expounded. To the launch vehicle with wind damp device, a rapid analysis method of wind damp effectiveness is presented, and validated by test. The rapid analysis method is used to filtrate many blue prints of wind damp device early, so it has directive significance for engineer. In addition, parameters are researched and presented, which have an effect on wind damp effectiveness.%阐述了运载火箭竖立风载计算方法,针对安装防风减载装置的火箭,提出了一种简易快速分析防风减载效果的方法,并通过试验验证,该快速分析方法可以为火箭多种防风减载装置初始设计筛选提供帮助,具有重要工程指导意义.另外,还研究给出了影响减载效果的设计参数.
