为进行更加准确的风洞试验,讨论了针对过失速机动的风洞动态试验的相似准则问题。从六自由度运动方程推导出了进行动态风洞试验需要满足的运动相似参数;从N-S方程中得到满足流动相似的相似参数。针对不同类型的风洞动态试验,提出了具体对应的相似参数作为主要的模拟量。得到的结论可以为风洞动态试验参数选择提供参考。
In order to conduct more accurate wind tunnel tests, the similar criterion for the dynamic test of wind tunnels with stalling maneuvers is discussed. Based on the equations of motion of six degrees of freedom, the similar parameters of motion for the dynamic wind tunnel test are derived. Similar parameters that satisfy the similarity of flow are obtained from N-S equation. According to the different types of wind tunnel dynamic tests, the corresponding similar parameters are proposed as the main analogue. The conclusions obtained can provide references for the selection of dynamic test parameters in wind tunnel.
