Solid Rocket Motor NDE Using Nuclear Magnetic Resonance

Solid rocket motors (SRMs) are complex integrated structures. An integral part of an SRM is the adhesive liner, which is used to bond the propellant to the insulator covering the inner surface of the case. In order to ensure SRM performance and reliability, the adhesive liner must be properly cured, of the specified thickness, and free of contamination. The goal of this study is to demonstrate the feasibility of a nuclear magnetic resonance (NMR) method to ensure that these conditions are met.
