Expanded Ignition Effectiveness Tests of Selected Igniter Materials with Navy Propellants
Abstract
Diagnostic ignition experiments have been conducted using a high-pressure flow through combustor to evaluate the ignition effectiveness of black powder, boron potassium nitrate, magnesium-teflon-viton, nitrocellulose, boron molybdenum trioxide and ammonium perchlorate with five propellants--NACO, NOSOL-318, NOSOL 363, LOVA, and PYRO. Twenty-one series of experiments have been conducted to determine the ability of various igniter materials to ignite gun propellants beyond the immediate vicinity of the gun igniter--that is after filtering through and being cooled by an inert propellant simulant zone positioned between the igniter and the live propellant. The ignition effectiveness has been determined quantitatively by the amount of igniter thermal energy, based on its heat of explosion, required to ignite a propellant 50 percent of the time. Analyses and results are given which present the relative effectiveness of the igniter materials in terms of the different ignition stimuli (e.g., gases, liquids, and solids ratios). (Author)
