TESTS ON IGNITION CAPABILITY OF GAS FROM A PROPANE-BUTANE CYLINDER AFTER SHOOTING IT THROUGH

Abstract

The paper presents a methodology and re-search results over propane-butane (P-B) gas cylinders hit by various projectiles fired with a firearm for assessing the susceptibility on initiation a fire (ability to initiate the fire) at the shooting. Cylinders were arranged in two configurations: the cylinder alone, or the cylinder with an armour plate behind it. During the tests, the projectile flight, a gas cylinder behaviour and the temperature released during the projectile impact to the P-B gas cylinder were measured using a high-speed camera (FASTCAM SA-Z 2100K 50.400 fps) and thermal cameras (FLIR X6580sc, FLIR X6901scSLS). The mass of liquid P-B gas in a cylinder at the tests was between 0.511.0 kg.
