Abstract
Dynamic Radioscopy technique was developed to observe internal phenomena of motors during firings. For use of this technique, generator and image box consisting of conversion screen, mirror, and video camera were designed and fabricated at our laboratory, and static firing tests were conducted to small motors. Protection devices against vibration and noise induced from during combustion were also made and their performances were evaluated with reference to the vibration criteria. Test results have shown that the vibration levels at concerned points were measured less than vibration criteria, and the internal phenomena during firings were also observed clearly.
