Hydrodynamic Stabilization of Supercavitating Underwater Bodies

In order to stabilize the motion of supercavitating underwater bodies, the damping action of the stern elastic interceptors which glide along the cavity surface is used. The results of calculation of normal forces on planing interceptors at the Mach numbers below 1.5 with a detached and attached shock wave are obtained. These results agree satisfactorily with known theoretical solutions and experimental data.
