Abstract:

This report details the investigation and results in the evaluation of the compatibility of various elastomeric compounds that may be used in the transfer and containment of liquid propellants LPs currently under development by the US Army. Hydroxyl Ammonium Nitrate HAN-based LPs are monopropellants composed of an oxidizer HAN and a fuel an aliphatic amine nitrate. The HAN- based LP used in this study has the designation of 1846. It is a water-based propellant with a density of approximately 1.4gcc. The fuel component of the LP-1846 is triethanol ammonium nitrate. The Army foresees using LP-1846 in a regenerative injection system for 155mm guns. The regenerative system involves the use of a piston forcing the LP, in the form of a jet or a spray, into the gun chamber during the combustion process, thereby controlling propellant combustion.
