摘　　要：介绍了多柱桁架式平台CT Spar的基本特征,并对立柱式平台在0°、7.5°、15°和22.5°4种不同方向的来流作用下分别进行9组不同雷诺数的CFD建模及计算,然后对系列计算的结果进行分析,并比较了不同方向来流下升力系数、阻力系数等流场的重要特征,最后给出了来流方向对多柱桁架式平台绕流流场的影响和作用。In this paper ,basic characteristics of Cell Truss Spar are presented. A series of calculations about CT Spar under four different directions of current： 0, 7.5, 15 and 22.5 degrees, as well as nine settings of Reynolds numbers respectively are carried out. The results of these calculations including CI/Cd coefficients are analyzed and compared. Influences and impacts of current directions on flow field of CT Spar are summarized in the end.
