SOLID PROPELLANT STRUCTURAL INTEGRITY INVESTIGATIONS. DYNAMIC RESPONSE AND FAILURE MECHANISMS.

Abstract

Program effort is concentrated on the study of propellant dynamic physical properties and structural failure phenomena. Activities of the current report period are summarized below. A cyclic heat rise test with constant amplitude shear strain excitation and isothermal boundary conditions was completed. Stress relaxation characterization was completed for the Polycarbutene-T cross-link density formulation variations. Significant variations in relaxation response were observed for these propellants. Electrical investigation of Nitroplastisol propellant and ingredients is in progress. These materials have been found to be much more electrically active than the polybutadiene base propellants. Selected formulation variations are being recast for investigation of the effect of these variations on failure under multiaxial stress fields. (Author)
