2D Lift Curve Slope in Flow over Airfoils and Wings Formulas

The 2D Lift Curve Slope is a measure of how rapidly the airfoil generates lift with a change in angle of attack. And is denoted by a₀. 2D Lift Curve Slope is usually measured using the 1 per Radian for Reciprocal Angle. Note that the value of 2D Lift Curve Slope is always negative.
