Abstract : Combat aircraft fueled with JP-4 are prone to fire and explosion when their fuel tanks are struck with incendiary projectiles. A program was carried out to develop additives that reduce the flammability of the liquid phase of JP-4 under these conditions. A broad spectrum of additives were considered, involving the screening of eighty-four potential additives. The most promising ones were those that imparted viscoelasticity to the fuel. Of these, natural rubber in conjunction with a water emulsion, as a heat sink, was the most effective. However, it was not possible to completely eliminate liquid phase fuel ignition by incendiary projectile. It is recommended that further work be carried out to develop a reduced vapor pressure fuel for use in combination with viscoelastic additives. (Author)
