| 摘 要： | 系留气球是一种应用广泛的空中平台。其运动特性是球体和系留缆绳两者的复合,总体气动布局、系留缆绳参数及风场环境对其稳定性影响非常显著,运动模态不同于一般飞行器。本文通过对球体和系留缆绳的受力特性分析,建立了其纵向运动学方程及其运动学方程的求解方法,分析了在不同风场环境下的运动模态,并数值仿真了在阵风作用下球体和系留缆绳的动态响应特性。

| Abstract: | Tethered aerostat is widely used as an aerial platform.Its dynamic characteristics are dynamic coupling between the balloon and the tether cable.Aerodynamic configuration,tether cable parameters,and wind field environment have notable influences on its longitudinal stability.Modes of motion are different from conventional vehicles.By means of analyses of force characteristics,a longitudinal dynamic equation is derived and a solution approach to the equation is given.A mode of motion analysis in different wind fields and a numerical simulation of dynamic responses of the balloon and cable to gust are carried out. |

| Keywords: | tethered aerostat stability tether cable mode of motion numerical simulation |
