本文针对二维多段着陆翼型,采用CFD方法研究了有/无缝翼滑轨舱密封件对该翼型气动特性的影响。结果表明:加上密封件以后,密封件部分保持了主翼头部外形,修复了缝道的形状,使整个翼型的流场情况大大好转,有密封件时升力系数恢复很快,而且阻力系数基本形态与正常外形工况时的阻力水平相当。
In this paper, a two-dimensional multi-section landing airfoil, the CFD method is used to study the influence of the / wingless rail seal on the aerodynamic characteristics of the airfoil. The results show that the sealing part maintains the shape of the main wing head and repairs the shape of the slits, which greatly improves the flow field of the whole airfoil. When the sealing part is provided, the lift coefficient recovers quickly and the drag coefficient The basic form and the normal shape conditions when the resistance level quite.
