| 摘 要： | 针对纵列式双旋翼桨叶的几何特征、运动方式及气动特性,建立了基于动量源方法的纵列式直升机双旋翼/机身组合流场的数值模拟方法,该方法中采用的非结构网格能综合考虑双旋翼/机身干扰流场特点且满足动量源计算网格要求。通过算例的计算值与试验值的对比,验证了本文方法的有效性,然后采用该方法分析了悬停及前飞状态下纵列式直升机的双旋翼/机身干扰流场特性。

| Abstract: | For the consideration of movement,geometric and aerodynamic characteristics of tandem twin-rotor,a computational method based upon momentum-source method was established to predict the interactive flowfield of the configuration of tandem twin-rotor and fuselage.In this method,unstructured mesh model for fitting the code of momentum-source and the calculation of interactive flowfield has been given.By the comparisons of calculated results with experimental results for numerical example,the present CFD method... |
