Abstract

A generalized method for the prediction of a stagnation point location as a function of the angle of attack on symmetrical and cambered wing, and airfoils with varying thickness distribution, is developed using airfoil design software and conformal mapping. The method presents relationship between the stagnation point location a function of the angle of attack, airfoil thickness, degree of camber, and the location of maximum camber.

The conformal mapping method and Designfoil software are used to determine the correlation between Ds, angle of attack and airfoil thickness for symmetrical airfoils. The equation for Ds for the flat plate and the chord normalized x coordinate along with the angle of attack is used to calculate the stagnation point location on the symmetrical airfoil.
