The invention discloses a high gliding parafoil with a leading edge slat and a working method of the high gliding parafoil. A parafoil canopy structure is composed of a conventional parafoil canopy and the leading edge slat. The slat is located above the front edge notch of the canopy, and the two chordwise sides of the slat are sewn with the upper wing surface fabric and the fins of the parafoil. When the parafoil works, the slat swells, a gap for air to pass through is formed between the slat and the upper airfoil, kinetic energy of appendage airflow of the upper airfoil is increased, airflow distribution of the upper airfoil is improved, airflow separation during large-attack-angle flight of the parafoil is effectively restrained, the maximum lift-drag ratio of the parafoil can be increased, the stall attack angle can be increased, and the flight stability of a parafoil system is improved. And the method is of great significance to the structural design of the high-gliding parafoil.
本发明公开了一种有前缘缝翼的高滑翔翼伞及其工作方法,翼伞伞衣构型由常规翼伞伞衣和前缘缝翼组成。缝翼位于伞衣前缘切口上方,弦向两侧与翼伞上翼面织物以及肋片缝合。翼伞工作时缝翼鼓包,与上翼面之间形成可供空气通过的缝隙,增加上翼面附体气流的动能,从而改善上翼面气流分布,有效抑制翼伞大攻角飞行时的气流分离,既能提高翼伞最大升阻比,又能提高失速攻角,增加翼伞系统的飞行稳定性,对高滑翔翼伞的结构设计有重要意义。
