ABOUT RADIATION BY THE SINGLE TRANSDUCER OF WAVEGUIDE TYPE THROUGH ITS WATER FILLED APERTURES IN THE SEMI-INFINITE SPACES

For single transducer of waveguide type formed by a coaxial set of piezoelectric cylinders with phased excitation as the running wave, the decision of a problem on radiation through its water filled apertures in the adjoining with them semi-infinite spaces is received. Examples of calculations of distributions of the normal components of oscillatory speed in face-to-face and back apertures, the frequency characteristics of sound pressure at radiation in a face-to-face and back direction are resulted, and also - directional characteristics. Influence of constructional parameters of the transducer of waveguide type on the specified characteristics is analyzed.
