DEVELOPMENT OF NONDESTRUCTIVE TESTING TECHNIQUES FOR LARGE SOLID-PROPELLANT ROCKET MOTORS

Abstract

A study way made to evaluate the capabilities of nondestructive test methods best suited to the detection of critical defects in large solid- propellant motors. A critical defect may be defined as an imperfection in a motor which will impair the success of an assigned mission. Two general types of defects are classified as critical regardless of their size. These are a case- insulation unbond exposed to propellant gases, and any defect which tends to propagate without limit. Analytical studies suggested that certain configurations of propellant-liner unbonds and cracks may propagate. Experimental studies conducted with a PBAN propellant showed no evidence of defect propagation.
