| 摘 要： | 根据翼身干扰形成的位移效应、升力效应、不对称效应、粘性效应等流动现象和原理,从流动机理上分析讨论了上单翼布局飞机整流罩的减阻原理;对上单翼布局飞机,提出一种整流罩设计形式,并对该整流罩各部分对气动性能的影响进行详细分析,采用RANS方程求解流场,以翼身组合体为基准,对整流罩的6个主要参数逐一变化,将每个参数的不同取值的计算结果各自对比,从流动原理上对数值模拟计算结果进行了分析,得出了上单翼布局飞机整流罩设计的几点思路。

| Abstract: | This paper analyze the drag reduction principle of the aircraft′s cowling region,on the basis of the displacement effect,lift effect,asymmetric effect,viscous flow effect that result from the wing-body interference.Taking the wing-body with high wing as the example,It has been discussed that the vary configuration of cowling affected on the change of aerodynamic characteristic,by calculating the RANS equations.In the paper,six factors which control the shape of the cowling has been chosen,changing one of these factors alternately and calculating each configuration,and comparing the results.At last,it concludes the several principles about cowling design from the analysis of the results rely on the flow mechanism. |
