Spectroscopic Characterization of HAN-Based Liquid Gun Propellants and Nitrate Salt Solutions

Abstract

The high heating rate thermal decomposition of HAN and LP1845 was conducted using the FTIR/temperature profiling technique. The crystal structure of pure HAN was obtained. Models of the behavior of these materials during decomposition were developed. Very concentrated aqueous metal nitrate salt solutions were also investigated at high temperature and pressure by Raman spectroscopy to gain an understanding of the properties of HAN under similar conditions. To determine the feasibility of non-intrusive droplet studies by IR spectroscopy, acoustic levitation was developed as an IR spectroscopy, sampling technique. Keywords: Hydroxylammonium nitrate, Liquid gun propellants, Nitrate salt solutions, FTIR spectroscopy, Raman spectroscopy, Thermal decomposition.
