| Abstract: | Problems arising in the ultrasonic pulse echo method for the measurement of the liner thickness in solid propellant rocket motors are considered. A new ultrasonic method using the Lamb wave is presented and its principle is introduced. Thickness of the internal liner is measured from the outer surface of solid propellant rocket motor case. Some measured results are given. |
