Abstract:
This report covers a one-year program of work concerned with the development of instrumented Structural Test Vehicles STVs, studies related to damage accumulation with propellants and studies of systems analysis as applied to solid propellant motor design. Section 2 of this report details the experimental propellant characteristization tests. Stress relaxation and failure data are given as well as the effects of storage on the propellant properties. Section 3 considers STV design and the instrumentation problem areas. Section 4 details the analytical work performed for the STV configurations and the gage-grain problem area. Two new computer programs are given and the problems of material nonlinearities are reviewed. Also, experimental STV stress-strain data are compared with the analytical predictions. Section 5 is concerned with two areas related to cumulative damage 1 the use of propellant volumetric dilatation as a damage index and 2 the calculation of transient thermal stresses. Section 6 illustrates the technique for using a systems analysis approach to rocket motor structural design problems by means of a specific example. Author
