UV/Vis Emission From Shock-Loaded Liquid Propellant XM46
Abstract
In flyer plate impact experiments conducted to study the response of the liquid propellant XM46 to shock loading, it had been observed that, in cases where the sample reacted violently, a luminous wave would travel at high velocity across a free-surface or container boundary prior to significant acceleration of materiel. This report presents the results of experiments in which the ultraviolet (UV) and visible (vis) radiation from this wave were spectrally resolved. The emission spectrum was found to be a broad, nearly structureless continuum that extends from a short wavelength onset near 400 nm to the long wavelength limit of the detection system at approximately 800 nm. It is considered that this signature is attributable to emission from electronically excited NO2. Mechanisms that might explain the experimental observations are discussed.
