The invention belongs to the field of aircraft aerodynamic layout design, and relates to an aircraft wingtip pylon appearance structure which comprises a pylon body and a launching beam, the pylon body is cylindrical in appearance, the cross section of the pylon body is circular, the diameter of the pylon body is larger than the thickness of a wing, and the launching beam is arranged on the side, away from the wing, of the pylon body. The upper surface and the lower surface of the launching beam are arranged in the tangential direction of the hanger body. When airflow flows from the front edge to the rear edge of the pylon, as the transition among the wings, the pylon main body and the launching beam is smooth, the flight resistance is effectively reduced, the lift force of an aircraft can be increased, the head lowering moment of the aircraft can be increased, the subsonic induced resistance can be reduced, the static instability of the aircraft can be reduced, and the longitudinal aerodynamic characteristics of the aircraft can be improved. The method is suitable for appearance design of the aircraft wingtip pylon.

    本申请属于飞机气动布局设计领域,为一种飞机翼尖挂架外形结构,包括挂架主体和发射梁,挂架主体外形为圆筒形,挂架主体的横截面为圆形,挂架主体的直径大于机翼的厚度,发射梁设于挂架主体远离机翼的一侧,发射梁的上表面与下表面均沿着挂架主体的切线方向设置。气流沿着挂架的前缘至后缘流动时,由于机翼、挂架主体和发射梁之间的过渡较为平滑,从而有效减少了飞行的阻力,能够增加飞机的升力,增加飞机的低头力矩,减小亚音速诱导阻力,减小飞机的静不安定度,改善飞机的纵向气动特性。该发明适用于飞机翼尖挂架的外形设计。
