An Ultrasonic Detecting Method for the Base Gap

摘要

In order to detect whether there is a base gap between the explosive charge and the inner cone of a shell and ensure its fighting performance, an ultrasonic inspection method of base gap is proposed based on the principle of conservation of sound flux in propagation and the special construction of the shell. Inspection of artificial base gap on the inner cone and actual measurement on shell bodies shows that the method can identify the base gap effectively.
