Abstract : A series of vertical gunfire tests was conducted at Wright-Patterson AFB in order to assess the effectiveness of fuel additives in reduction of the fire and explosion hazards that can be associated with kerosine (JP8) fuel under gunfire conditions. This program considered commercial additives which have been developed for the fire-safe fuel efforts of the FAA, the Army, and the British Government. The additives were intended to prevent fuel mist or spray during a crash situation. This effort considered the effectiveness of these additives at a concentration of approximately 0.3% wt. in the prevention of explosions of fuel mist or spray as a 50 calibre armor piercing incendiary ordnance round passes through the liquid-vapor interface. Results indicated that additives could be effective. Two of the four materials reduced average pulse pressure rise to less than 10 psi as compared to 40 psi rise with neat JP-8. Additives were not effective when evaluated in JP-4 fuel. (Author)
