In the paper, the proofs of theorems formulated in the work by S.E. Gazizova, D.V. Maklakov (LJM, 42 (8), 2021) are sketched out. The theorems serve as a basis for designing supercavitating hydrofoils that have a minimum drag coefficient for a given lift coefficient. Thus, the maximum lift-to-drag ratio is achieved.
Mots-clés : nonlinear functional, absolute minimum, Jensen's inequality.
