| 摘 要： | 使用等效集中涡和输入涡来模拟边缘离体涡的涡格法,在本文中应用到边条机翼布局的气动力计算中。在进行边条机翼的“混合流型”的气动力计算时,对边条采用了产生离体涡的计算模式,在主翼上则采用了附着流动的计算模式。使用这种方法,对两组边条布局进行了计算,计算结果与实验数据进行了比较。

| Abstract: | The equivalent concentrated vortex method1] is employed to the strake-wing configuration aerodynamic characteristics calculations. When the so called "mixed flow partten" concept is adopted, flow over a strake-wing is characterized by the leading-edge seperated vortex flow of the strake and the attached flow of the basic main wing, and the similar treatment for the slender wing could be used for the strake, and a conventional vortex lattice method could be used for the basic main wing. In this way, calculations were performed to estimate the aefodynamic characteristics of several strake-wing configurations. Results show good agreement with the experimental data. |
