Finding the shape of the profile of aero-hydrodynamical lattice by given chord diagram of velocity distrubution

The inverse edge problem of lattice aero-hydrodynamics is considered, in which it is necessary to find the shape of the lattice profile streamlined by the potential flow of incompressible non-viscous liquid, when the distribution of the velocity value on it is set as a function of the abscissa of the profile point (chord diagram), the lattice period (modulo) and the ratio of complex liquid flow rates before and after the lattice are known.
