Vulnerability Assessment of JP-4 and JP-8 under Vertical Gunfire Impact Conditions

Abstract

This report presents results of tests conducted to determine effects of a fifty-caliber incendiary projectile penetrating vertically from the bottom into a partially-filled fuel tank. Fuel types investigated in this program are JP-4 (high volatility fuel) and JP-8 (low volatility fuel). This test program was carried out in two phases: (1) 'nonequilibrium' tests conducted with a cylindrical tank to determine effects of fuel temperature, initial ullage pressure, tank volume, fuel depth, venting, etc. and (2) equilibrium tests conducted with various rectangular tank configurations to determine effects of initial fuel-air mass ratio of the ullage fuel-air mixtures on ignition and reaction overpressures.
