Abstract:

At the end of the primary technical effort on this program, a number of specimens were in storage for evaluation after an extended storage period. The specimens to be evaluated included a segment of a TM-3 test motor 6-in. web, analog physical property motors, tensile specimens, and 2-in. propellant cubes. The TM-3 motor grain developed fissures in less than 6 months. The analog motors swelled sufficiently to preclude internal bore measurements, thus eliminating the analog motor thermal test. Tests of tensile specimens stored up to 1 year at 25 and 35 C including propellant batches containing magnesium-treated LMH-1 and standard LMH-1 revealed no effects on physical property stability that might be attributed to LMH-1, nor was there any noticeable difference in behavior between the two types of LMH-1. A comparison of propellant formulations UTP-6814 and UTP-8812 based on the evaluation of 2-in. cubes stored for periods up to 2 years clearly established the superiority of the polyester binder system over the UTEFLEX binder system at the current state of development. Dubes of propellant formulation UTP-6814 stored for 2 years at 95 F and 0 percent relative humidity remained in excellent condition.
