摘　　要：对固体火箭发动机药柱的超声检测方法进行了研究,介绍了超声特征扫描成像原理及缺陷检测方法,研制了药柱超声波特征扫描系统。并用低频组合探头对药柱进行了检测。试验表明,设计的超声特征扫描系统可采用幅度成像、深度成像方法显示药柱的缺陷。An ultrasonic testing method for solid propellant of rocket engine is studied. The principle 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 combined transducers. The experiment shows that the ultrasonic feature scan imaging system can demonstrate the defects of solid propellant successfully by adopting amplitude imaging and depth imaging.
