摘要
针对小型系留气球尾翼设计周期长、参数调整复杂的问题,使用了建模仿真的方法:逐个改变决定系留气球尾翼构型的几个参数(弦长、高度、相对位置及尾翼夹角),建立了不同尾翼构型下的系留气球模型;并使用Fluent对这些模型进行了仿真计算。得到了小型系留气球气动特性随几个决定尾翼构型的关键参数变化的规律以及变化幅度。计算结果表明,修改尾翼构型时应该优先调整弦长、尾翼相对位置应该尽量接近球尾、下尾翼夹角90°较为合适。
Aiming at the problems of long design period and complex parameter adjustment of small tethered balloon tail, the method of modeling and simulation is used: changing several parameters(chord length, height, relative position and tail angle) that determine the configuration of tethered balloon tail one by one, then establishing the tethered balloon models with different tail configurations. The simulation calculation of these models is carried out with Fluent. The aerodynamic characteristics of the small tethered balloon with several key parameters which determine the configuration of the tail are obtained. The results show that the chord length should be adjusted first and the relative position of the tail should be close to the ball tail and the angle between the lower tails should be 90 degrees when modifying the configuration of the tail.
