A wing of an aircraft comprises an upper wing surface and a lower wing surface, wherein at least a portion of the airfoil in the airfoil span direction is arranged such that, when viewed from a cross-section of the portion of the airfoil, the upper airfoil and the lower airfoil converge at a leading edge point, and the lower airfoil includes a lower airfoil leading edge portion extending from theleading edge point toward a rear side of the airfoil, where the lower airfoil leading edge portion has a larger radius of curvature. The aerofoil profile can improve the flight performance of an airplane, such as improving the stall critical attack angle, the maximum lift coefficient and the like. The invention further discloses an aircraft comprising the wing.
一种飞机的机翼包括上翼面和下翼面,其中,该机翼的沿机翼展向的至少一部分被设置成,当从机翼的该部分的横截面来看时,上翼面与下翼面会聚在前缘点处,且下翼面包括从前缘点开始朝着机翼的后侧延伸的下翼面前缘部,其中,下翼面前缘部具有较大的曲率半径。该机翼翼型能够提高飞机的飞行性能,例如提升失速临界迎角、最大升力系数等。还公开了一种包括该机翼的飞机。
