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。
A method to calculate the erection wind load of launch vehicle is described. Aiming at the rocket with wind load and deload device, a simple and quick method to analyze the effect of wind and load shedding is put forward. The method is validated by experiments. Installation initial design screening to help, has important engineering guidance. In addition, the design parameters that affect the load shedding effect are also given.
