Ultrasonic Quality Control of Hydroacoustic Antennas

Аннотация

We consider the problem of nondestructive quality control of complex structured articles, in particular, hydroacoustic antennas. Those features in the structure of these products are determined that affect the choice of methods and means of such control. The possibility of using ultrasonic methods (in particular, the pulse echo method with immersion technique of acoustic contact) and means for monitoring the quality of hydroacoustic antennas have been investigated; means have been proposed to ensure the automation of control.
