FEASIBILITY DEMONSTRATION OF LARGE SEGMENTED SOLID PROPELLANT ROCKET MOTOR WITH DUAL TVC SYSTEM AND THERMAL GRAIN STRUCTURAL ANALYSIS

Studies were conducted to determine the effects of cyclic temperatures in producing failures in case-bonded solid propellant grains. during this report period an extensive uniaxial experimental program was scheduled for the determination of thermal effects on propellants. A collection of limit elastic solutions for casebonded grains subjected to thermal inputs was completed and the problem of determining suitably expressed temperature distributions in grains was studied. The problem of transient temperature cycling of uniaxial samples was examined.
