摘要

One of the problems of study of advanced cavity flows is the estimation of acoustic radiation of an advanced cavity. It is considered the advanced artificial cavity formed for cavitatorfor Mach numbers M < 1. At ablation of gas from a cavity by means of periodically coming off portions, a pulsing cavity is formed The periodic changes of volume of the cavity are accompanied by low-frequency acoustic radiation to the environment. It is developed the acoustic model of the advanced artificial cavity as equivalent of radiator (oscillator), the surface fluctuations of which are determined by styles of the zero and first order.
