In the present work the method of the inverse boundary‐value problems is used to obtain upper estimates for two main integral airfoil characteristics: lift coefficient C l and the aerodynamic ratio K in a certain class of airfoils flown by an incompressible flow of viscous fluid at a fixed angle of attack at high Reynolds number (10 6 —10 7 ) with the presence of a thin non‐separating turbulent boundary layer.
