Abstract:

The evaluation of emulsified JP-4 concentrated upon the fuel properties which relate to the ignition and propagation of fire under the conditions of ballistic attack and survivable aircraft accidents. The specific areas of study and testing include the following 1 fuel combustion rates as a function of air velocity and air temperature, 2 fuel vaporization rates under closed-tank and vented-tank conditions, 3 fuel permeability, 4 fuel dispersion characteristics under conditions of high-velocity ballistic impact and spillage from heights to 20 feet, 5 ease of fuel droplet or spray ignition with various energy sources, 6 fuel and tank panel behavior when hit by functioned incendiary bullets, 7 fire extinguishing ease with a variety of extinguishants against a standardized fire, and 8 self-sealing panel performance with fuel emulsions. It was concluded that emulsified fuels offer opportunities for greater aircraft survivability from several standpoints. They may be employed most advantageously as a part of a total passive defense system for aircraft fuel.
