並列タイトル等On the Ultrasonic Inspection of Separation in Solid Propellant Rocket motors
タイトル(掲載誌)航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-308
一般注記This paper describes the capability of an ultrasonic inspection technique to detect separation at the case-liner and liner-propellant interfaces, this being one of the most serious defects in solid propellant rocket motors. It is reported that the ultrasonic multiple reflection method now being used in factories, is most effective in detecting case-liner separation, but is not very effective is detecting liner-propellant separation. As a result of our experiments using rocket models, it is found that a multiple reflection method is capable of detecting not only case-liner separation but also liner-propellant separation if a continuously variable frequency oscillator is used and the reflectograms are analyzed considering interference.
