摘要
针对轻型运动飞机进行翼身整流设计,提出了一种快速的翼身整流曲面设计方法。使用该方法设计的翼身整流曲面,能满足飞机外形对曲面连续性的要求;同时,采用CFD方法,将其与圆角过渡曲面生成方法设计的翼身整流曲面进行对比,发现用该方法设计的翼身整流曲面能减小机翼与机身之间的气流分离现象,从而减小飞机的飞行阻力。
A newand rapid wing-body junction surface design method is presented for the light sports aircraft. The wing-body surface's continuity condition can be met by using this method to create the surface. Besides,the flowseperation can be decreasedbetween the wing and body by using the newmethod compared with the transitions method,and the aircraft's flight resistance is also reduced by calculatingwith CFD.
