Abstract: In this paper, for profiles flowed according to the Helmholtz–Kirchhoff scheme with infinite cavern, we investigate values of coefficients of levitation force and of resistance related to a length of washed part of the profile. Under given value of coefficient of levitation force and additional restrictions from above and below on a distribution of a speed on a surface of a profile we find global minimum of coefficient of resistance.
Keywords: extremal problem, ideal fluid, Helmholtz–Kirchhoff scheme, cavitation flow.
