The present paper reports on ingnition studies performed at EMI-AFB investigating the electrical ignition of the hydroxylammonium nitrate (HAN) based liquid gun propellant LP 1846. The goal is to develop an ingiter system suitable for regenerative liquid propellant guns. Several ingiter configurations, designed by the Ballistic Research Laboratory (BRL) and the Ernst-Mach-Institute EMI-AFB, have been tested. Voltage and current as well as the pressure histories were measured for each discharge. A theoretical analysis yielded improved electrode designs for furture testing.
