WebTo calculate Lift Curve Slope for Finite Wing, you need 2D lift curve slope (a 0), Induced lift slope factor (τ) & Wing Aspect Ratio (AR). With our tool, you need to enter the respective … Web30 sep. 2015 · The lift curve slope of a flat plate is the same as that of regular airfoils, complete with stall. They have a zero-lift angle of attack of 0° (obviously) and separated flow on the suction side. The maximum lift coefficient of 0.7 to 0.8 is reached at moderate angles of attack - details depend on the aspect ratio .
