Resumo
In the paper, we present an analytical inverse nonlinear method of designing supercavitating hydrofoils by a given velocity distribution on the foil surface with allowance for the physical realizability of the obtained flows. The role of the pressure load near the leading edge (hydrofoil nose) for obtaining one-sheeted flow domains is revealed. It is shown that even the noses of very small sizes of order 10−3–10−2 of the hydrofoil chord lead to a very significant decrease of the lift-to-drag ratio.
