| Results of experimental investigation and computer simulation of the unsteady processes during supercavitating body motion in water are presented. Mathematical model based on G.V.Logvinovich principle of independence of cavity expansion is used. Calculation results are compared with experimental high-speed shooting. Method of approximate calculation of forces and moments, which act on a model at interaction with the internal cavity surface, is developed. Theoretical analysis of stability of the supercavitating model motion is given. |
