• Note (General): A swept frequency type ultrasonic inspection method is used for inspecting not only case-liner separations, but also liner-propelant separations of solid motors, with its successful application to the H-I upper-stage motors also being discussed. Over the past quarter of a century, Linear-propellant separations have never been practically inspected using conventional ultrasonic inspection methods. This new method has been in development at the National Aerospace Laboratory(NAL) since 1968, and is based on using the one-dimensional quarter-wavelength resonance principle to determine the liner thickness under one free and the other fixed end-face boundary condition, being considered to be the liner′s line-propellant separation boundary condition. Since the motor cases have curved (spherical/cylindrical) surfaces, several curved contact surface probes were developed. This method was subsequently applied to test successfully both the apogee and third stage motor of the H-I rocket during manufacturing and also at the launching site. This inspection has contributed to successful launchings of the H-I rocket since the first launching in August 1987, and will be applied to the Solid Rocket Booster (SRB) of the H-II rocket in the near future.; 資料番号: NALTR1107000; レポート番号: NAL TR-1107
