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.
