【 摘 要 】

The paper presents the formulation of the problems and calculation method of the cavity geometry in real conditions. The calculating procedure used here is based on the method of small perturbations of the thin body. The calculation results and their comparison with the experimental data for the following cases are presented: cavity axis deformation under the effect of gravity forces, cavity behind elliptical cavitator, cavity behind cavitator at nonzero attack angle, the pressure pulsations in the cavity, the motion near boundaries and others.
