The invention relates to the field of aircraft design, in particular to an aerodynamic layout structure of a light sports aircraft with ultra-short take-off and landing, which comprises a nose, a fuselage, wings, a vertical tail, a horizontal tail and an elevator, and when the fuselage extends from the nose to the tail, the shape of the fuselage changes from a streamline curved surface to a rectangle. The wings comprise a left main wing and a right main wing which are symmetrically designed and fixed on the fuselage, leading edge slats are also arranged at the leading edges of the left main wing and the right main wing, a fly unfolding aileron is also suspended below the trailing edges of the left main wing and the right main wing, a horizontal stabilizer of the horizontal empennage is arranged at the top, the elevator is rotationally arranged at the trailing edge of the horizontal empennage, and a balancing sheet is also arranged at the trailing edge of the elevator. The horizontal empennage is inverted, so that the pressure of the lower airfoil surface of the horizontal empennage is smaller than that of the upper airfoil surface, a downward pressure difference is further generated, the clockwise couple moment borne by the whole aircraft is increased, and the minimum ground clearance speed is reduced. The aircraft wing combines the advantages of the slats and the flaps, the landing appearance stall speed of an aircraft is effectively reduced, and therefore the landing taxiing distance is reduced.

    本发明涉及飞机设计领域,具体涉及一种超短距起降的轻型运动飞机气动布局结构,包括机头、机身、机翼、垂直尾翼、水平尾翼和升降舵,机身自机头向机尾延伸时,其外形形状由流线性曲面形向矩形变化,机翼包括对称设计并固定于机身的左主机翼和右主机翼,左主机翼和右主机翼的前缘还设有前缘缝翼、后缘下方还悬挂安装有展襟副翼,水平尾翼的水平安定面在顶部,升降舵转动安装在水平尾翼的后缘,升降舵的后缘还安装有配平片。水平尾翼倒置使平尾下翼面压力小于上翼面压力,进而产生向下的压力差,飞机整体所受顺时针方向的力偶矩增大,降低最小离地速度。飞机机翼结合缝翼和襟翼的优点,有效降低飞机的着陆外形失速速度,从而减小着陆滑跑距离。
