摘要

A Mobile Combustion Diagnostic (MCDF) has been fabricated to investigate the chemical products produced from the combustion of propellants at pressures below 16 MPa. These data are required in order to better understand the combustion phenomenology of propellants at low pressures. The design and capabilities of the MCDF as well as preliminary chemical analysis of nonequilibrium ignition/combustion products using GC and FTIR techniques from hot wire initiated LOVA XM39 propellant are presented. The experiments were performed in both a closed bomb mode and vented chamber mode at various loading densities and pressures. It was found that greater amounts of nonequilibrium combustion products were produced under interrupted burning conditions than under closed bomb conditions and that these products decreased with increasing burst disc pressure and increased with higher loading density. Keywords: LOVA (Low Vulnerability Ammunition); Combustion and ignition; Combustion diagnostics; LOVA XM39 Propellant; Interrupted combustion; Combustion Gas analysis. (JES)
