We stated and solved a problem of designing a zero-moment airfoil when a separation-free flow passes around it at the calculated angle of attack by the velocity distribution specified on the airfoil outline. By a zero-moment airfoil we mean a wing profile with zero moment at zero lift force. The numerical and analytical method for designing such an airfoil in the context of the model of ideal incompressible fluid is based on the theory of inverse boundary-value problems of aerohydrodynamics. The separation-free flow around the zero-moment airfoil sought is due to the velocity distribution on the airfoil outline with regard to its hydrodynamic utility. We present examples of designing such airfoils.
