| 摘 要： | 本文在简化的前缘涡模型基础上,沿涡轴分布点源,以模拟细长翼涡破裂对气动特性的影响。对一组不同平面形状细长翼的计算表明,用本方法得到的结果在定性上与机翼在失速迎角前后实际的气动特性变化趋势是一致的。

| Abstract: | Based on the Brown and Michael vortex model for slender wings, the influence of vortex breakdown on the aerodynamic characteristics of slender wings is simulated by distributing sources along the vortex axes. The calculation for a set of slender wings having various planforms indicates that the variation of the aerodynamic characteristics around the stall angle of attack calculated by the present method is qualitatively in good agreement with that of the actual wings. |
