Applied ultrasonic detector by non contact method to production of 'S310' SRM, we confirmed that there are no flaws which exceed the acceptable size of flaw of S310. And we developed inspection system that could scan automatically, which reduced the inspection time by about 40 % compared with X ray inspection. This system has a merit that we can inspect at the launch site, because the constrain of the inspection location is less than X ray inspection. In the future is planned the confirmation for measuring the depth of flaws In the non-contact method, there is a problem for measuring the depth of flaws. The depth of flaws can be detected by shifting transmitter and obtaining a flat image. Improvement of received intensity The inner surface of propellant is curved, which inflect ultrasonic received intensity is reduced on the exterior surface of motor case. If this problem is improved, inspection time will be shorted by improvement of Signal-Noise ratio.
