Application of Near-Infrared Spectroscopy in Stability Testing of Shipborne Weapon Propellants

Abstract

Modern naval weapon propellants exhibit diverse compositions with varying components, particularly tri-base propellants representing the trend toward high energy and low vulnerability. Examples include tri-guanidine propellants, primarily composed of azidonitramine, nitroguanidine, nitrocellulose, nitroglycerin, dinitrotoluene, stabilizers, and performance additives. Compared to traditional single-base or double-base propellants, their composition is more complex. Interactions between components become more pronounced under harsh conditions, potentially accelerating the rate and severity of physicochemical changes induced by environmental factors. This heightens the urgency for rapid on-site detection and evaluation. This study investigates the application of near-infrared spectroscopy in detecting the stability of naval weapon propellants, aiming to promptly obtain fundamental performance data and enable real-time, accurate stability assessments. This research is crucial for ensuring the safety and reliability of naval weapons during maritime missions and safeguarding personnel lives.
