Abstract:

Previous tests of the 16-NS-1000, M15 Rocket Motor have established temperature limits of -20 F to 130 F for motors, ages five to seven years. This test was established to determine if the shelf life could be extended to eight years, and to determine what temperature limits would prevail. Seventy-two motors from field storage sites were visually and radiographically inspected, temperature conditioned and static fired. Thirty-three samples conditioned at -30 F performed satisfactorily. Seven motors fired after conditioning at 140 F, were determined to be unsatisfactory because of high chamber pressures, causing one motors pressure relief disc to rupture. Of three samples fired after conditioning at 130 F, the pressure relief disc ruptured in one motor. Twenty-five motors were then conditioned at 120 F and performed satisfactorily. The 16-NS-1000, M15 Rocket Motor will perform satisfactorily at age eight years between temperature limits of -20 F to 110 F. Author
