ABSTRACT

Some experimental results on high-speed motion of models in water are presented. An empirical formula for calculating the shape of axisymmetric supercavities is derived. Qualitative features of supercavities at velocities commensurable with the speed of sound in water are described. A new method of controlling the parameters of supercavities by controlling the resistance of the cavitation generator is implemented experimentally.
