Abstract A general formulation of the inverse boundary-value problem of aerohydrodynamics for v(s) is given for two angles of attack. This formulation includes that given in [10] as a particular case. An integral representation of the solution is constructed, and the conditions of consistency of the initial data and the solvability conditions are written down. For satisfying the latter the method of quasisolutions of inverse boundary-value problems [11, 12] is employed. A criterion is obtained for the absence of boundary layer separation as the angle of attack varies over a given range. This criterion is expressed in terms of the velocity distributions for the limiting positions. A method of specifying hydrodynamically expedient velocity distributions that takes into account the nonstalling conditions obtained is proposed. Questions of lift maximization are considered. The results of numerical calculations are presented.
