| Some techniques of control over performance of the radiating system, formed by coaxial cylindrical piezoceramic shells with the face screens in form of truncated cones, are considered. It is shown that a special choice of the electric voltage for each shell allows to fulfill an effective control over the acoustic power, providing simultaneously the absence of electrical and mechanical overload. |
