Abstract : The One InchDual Charge, Explosive Launch Bolt is used as the mating equipment to release the toggle hold-down mechanism of the Launcher which in turn releases the Titan I Missile. The purpose of this test was to obtain engineering data that could be evaluated to determine if its shelf and service life could be extended. A shelf and service life of 2 years was previously established by the manufacturer. Because of the expiration of this service life, it was necessary to replace the hold-down bolts after two years. One hundred and three bolts, which had been previously installed on missiles for two years, were function tested to determine if they were still serviceable. The bolts were temperature conditioned from -40 F to +160 F to demonstrate their functional ability under extreme conditions. All the bolts functioned satisfactorily and demonstrated a reliability of 99.6 % at 50 % confidence level. It was recommended that the shelf life be extended to 4 years and the service life to 3 years. (Author)
