8m×6m风洞升力干扰因子数值计算

8m×6m Wind Tunnel Lift Interference FactorNumerical Calculation

叙述了８ｍ×６ｍ风洞洞壁升力效应的模拟方法，计算了８ｍ×６ｍ风洞的升力干扰因子，并和８ｍ×６ｍ风洞现采用的干扰因子曲线以及低速风洞试验提供的资料值进行了比较。结果表明，本计算得到的干扰因子和资料值的一致性较好，说明所采用的模拟方法是可行的，此外，计算还给出了机翼偏离风洞中心和机身存在对升力干扰因子的影响。

Here are presented a numerical simulation method of the 8m×6m wind tunnel wall interference,the calculated lift interference factor,and the comparison of the numerical results with the data presently used in 8m×6m tunnel and the one from the reference 2. The results have shown there is better agreement between them,and it can be drawn that the simulation method is feasible.In the paper are also given the effects of a wing apart from the tunnel center and a fuselage on the lift interference factor.
