The invention discloses a rectification optimization design method for an upper wing surface of a parafoil. A rectification surface is additionally arranged on a conventional parafoil structure, and a canopy is composed of an upper wing surface, the rectification surface, bearing fins, non-bearing fins, a lower wing surface and parachute cords. The rectification surface sewing position is located at the middle position of the upper wing surface on the two sides of the bearing rib, and a double-layer upper wing surface is formed at the position; the rectifying surfaces wrap the grooves between the adjacent upper wing surfaces, so that the grooves are located in the canopy, the full shape of the canopy is optimized, friction resistance is reduced, and the lift-drag ratio of the parafoil is increased.

    本发明公开了一种翼伞上翼面整流优化设计方法。在常规翼伞结构上增加整流面,伞衣由上翼面、整流面、承载肋片、非承载肋片、下翼面和伞绳组成;整流面缝制位置在承载肋片两边的上翼面正中部位置,在该处形成双层上翼面;整流面将相邻上翼面之间的“凹槽”包裹住,使“凹槽”位于伞衣内部,优化伞衣充满形状,减小了摩擦阻力,提高了翼伞升阻比。
