本文计算了小展弦比机翼纵向和横侧气动特性,并计及涡破裂的影响。本方法以Purvis升力面理论和Polhamus吸力比拟为基础。并参照Lan方法进行大迎角特性修正。算例表明,本方法适用于小展弦比机翼气动特性的计算。
In this paper, the longitudinal and lateral aerodynamic characteristics of small aspect ratio airfoils are calculated, and the influence of vortex rupture is taken into account. This method is based on the Purvis lift surface theory and Polhamus suction. And revise the characteristics of high angle of attack with reference to the Lan method. The example shows that this method is suitable for the calculation of aerodynamic characteristics of small aspect ratio wings.
