| Abstract: | An ultrasonic testing method for solid propellant of rocket engine is studied.The princi- ple of ultrasonic feature scan imaging and the method of defect testing are presented.The ultrasonic feature scan imaging system for solid propellant is developed and the solid propellant is tested by using low-frequency com- bined transducers.The experiment shows that the ultra- sonic feature scan imaging system can demonstrate the defects of solid propellant successfully by adopting am- plitude imaging and depth imaging. |
