Compression-Ignition Sensitivity Studies of Liquid Propellants for Guns
Abstract
The objective of the study reported herein was to provide a means of establishing the sensitivity of candidate liquid monopropellants to compression-ignition at pressure levels and pressurization rates comparable to those of liquid propellant gun (LPG) systems, particularly during the start-up phase of the ballistic cycle. Experimental testing with a specially designed compression- ignition sensitivity apparatus was performed to delineate the safe operational domain for NOS-365 liquid monopropellant with respect to the hazard associated with compression-ignition of collapsing bubbles in the liquid charge and ensuing runaway reaction. It is the purpose of this study to define the threshold conditions required to initiate runaway reaction, in the presence of finely distributed ullage. Furthermore, the theory for the mechanism of ignition of liquid monopropellants by rapid compression is advanced by examining the assumptions and limitations of previous works.(Author)
