天空飞行与地面风洞实验动态气动相关性研究

Investigation on aerodynamic relation between real flight and wind tunnel

寻找天空飞行与地面风洞实验(及数值模拟)动态气动力不一致的因素是人们非常关心的课题,近10余年来,在3个动态气动专题领域内,空中飞行器动态气动特性与风洞自由飞实验结果多次的一致性,验证了一个新的命题:运动动力学(及运动自由度)模拟相似是天空飞行与地面风洞实验动态气动相关中的一个重要因素。

Searching for the aerodynamic force difference between real flight and wind tunnel experiment （and numerical stimulation） is a subject which has been long drawing people＇s great attention. In recent ten years , of the three professional fields in dynamic aerodynamics, the multi - coherence between real flight and wind tunnel free flight results of dynamic aerodynamics characteristics validate a new proposition： movement dynamics （with movement degree of freedom） simulation approximation is an important factor in the aerodynamics relation between air flight and wind tunnel experiment.
