 note = {グレインの製造能率と均質性の一段の向上が期待できる直填法によるポリウレタン～過塩素酸アンモニウム,系混成推進剤の製法を,直径100mm,長さ2,240mmのグレインを用いる内面燃焼型ロケットモータの製造工程を例にとって略述する.このグレインの特長は,硬化温度が50℃と低く,重合収縮や熱応力が最小限度にとどめられることである.モータのX線非破壊検査と,グレインの機械的性質の測定によって,気泡,き製などの欠陥のない,引張り仲度の高い,燃焼安定性に富むグレインが製造できることが確かめられた., A preparation method of polyurethane～ammonium perchlorate-based composite propellant and, as its illustrative application, the loading process and inspection method for a rocket motor using case-bonding grain of 100mm diam. X2, 240mm long, are described. The propellant dough is poured into the motor case directly to make the grain with good uniformity. It has long pot life and exhibits late gelation enough to fit the propellant dough for direct-casting operation. Curing temperature of 50°C is rather so low that excess thermal stress and shrinkage which may lead the separation of the grain periphery from the heat insulator or breakup of the grain matrix, can be avoided. It has been proved by a series of the none-destructive X-ray inspection in the grain-loaded motor and measurement of the mechanical properties on the grain samples that these propellant grains are free from vital mechanical defects and have good tensile elongation., 資料番号: SA0124886000},
