The invention relates to means for hydro-acoustic engineering for use in small-dimension hydro-acoustic devices. Hydro-acoustic antenna consists of coaxial set of open piezo-ceramic circular transformers electrodes of each of which are divided into equal sectors. To the ends of each of neighboring piezo-ceramic circular transformers, in pairs in N points, where N ≥ 3, arranged with angular separation 360°/N, flexible mechanical joints are attached. Flexible mechanical joints are installed at straight generatrixes of one-cavity hyperboloid of revolution with radius of mouth circle smaller than radius of piezo-ceramic circular transformer, and long axis of hyperboloid formed coincides with long axis of piezo-ceramic circular transformer. Distance between the ends of neighboring piezo-ceramic circular transformers H is determined by given formula. The invention improves technical design characteristics of hydro-acoustic antenna. |
