| 摘 要： | 尖切翼尖作为一种重要的翼尖装置,由于实现简单,能有效得减小机翼得诱导阻力且对飞机的其它性能影响小,而受到广泛的应用.基于数值模拟结果对尖切翼尖的前缘后掠角及根梢比对机翼气动性能的影响进行了对比研究.给出了前缘后掠角和根梢比对气动性能的影响规律,并通过分析涡位置和强度的变化,得出涡位置及强度和气动性能的关系.

| Abstract: | The sheared wing-tip,one kind of wing-tip device,is being used widely,because of its convenience of application and its good ability of reducing the induced-drag with litter influence on the other performance of the plane.According to the computational results,the study of compare about the influence on aerodynamic performance of the leading-sweep and the taper,was carried out in this paper.The relation between aerodynamic performance and the taper,leading-edge sweep angle was given out. |
