The Service Life Prediction Technology Program is part of the Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program under the area of Strategic Sustainment. The overall goal of IHPRPT is to double the state-of-the-art national rocket propulsion capability by the year 2010. The primary objectives of the Service Life Prediction Technology program are to reduce the uncertainty in predicted stresses and strains, to reduce material failure characterization uncertainties, and to reduce aging model uncertainties. Emphasis of the program will be to: (1) investigate and implement nonlinear constitutive laws (including laboratory characterization methods); (2) to characterize and model chemical migration and reactions in aging propellants and bondlines; and (3) to investigate and establish nondestructive methods which can be used to characterize the in-situ propellant properties and property variations in solid propellant rocket motors.
