Experimental Determination of the Ignition Limits of JP-4 Fuel When Exposed to Caliber .30 Incendiary Projectiles

Abstract

The report describes experimental efforts to define the ignition limits of JP-4 vapors subject to caliber .30 incendiary projectiles. A test fixture was fabricated which allowed a functioning incendiary projectile to pass through a known, uniform fuel/air vapor mixture. The resultant reaction was observed using high-speed photography. Ignitions between fuel/air ratios of 0.5 and 3.0% JP-4 volume were observed. Additional tests were conducted to observe the flame suppression properties of reticulated polyurethane foam (RPF) and to determine that the impact flash from inert projectiles can ignite combustible fuel/air vapors.
