通过CFD计算软件Fluent数值模拟和工程近似计算方法对同种翼型进行了压强系数计算,对两种不同迎角下相同翼型压力系数进行了计算对比,两种计算结果在允许的误差下符合精度要求,两种方法均可用于飞机初始设计阶段。
The CFD calculation software Fluent numerical simulation and engineering approximate calculation method were used to calculate the pressure coefficient of the same kind of airfoil. The same airfoil pressure coefficient under two different angles of attack was calculated and compared. The two calculated results accord with the allowable error Accuracy requirements, both methods can be used for the initial design phase of the aircraft.
