SOLID PROPELLANT STRUCTURAL INTEGRITY INVESTIGATIONS: DYNAMIC RESPONSE AND FAILURE MECHANISMS

Abstract

The results of an investigation of viscoelastic and failure properties of highly filled PBAA and PBAN propellants as a function of solids loading are reported. Failure surface study results are reported, and the results of a limited study of the relationship between crack propagation velocity and propellant physical characteristics are discussed. Propellant dynamic shear and bulk properties were investigated with small deformation piezoelectric devices. An experimental investigation of propellant thermomechanical response to sustained cyclic inertial loading was completed, and the results in agreement with theory are presented. Also discussed are experimental investigations of transient thermoviscoelastic response of propellant under constant cyclic strain amplitude and inertial loading.
