Abstract : The elimination of fire and explosion hazards in aircraft fuel tanks has been investigated. DOD and FAA tests have shown that a reduction of the oxygen concentration in the ullage gas to under 12 percent will prevent rapid propagation of the flame front and subsequent overpressure explosion. One means of providing the required reduction in oxygen concentration is to provide a source of inert (nitrogen-rich) gas which would replace fuel used, and flush out atmospheric oxygen and dissolved oxygen which may be released from the fuel. Molecular sieve pressure swing adsorption technology could be used to generate inert (nitrogen-rich) gas. A Molecular Sieve Inert Gas Generator (MSIGG) was designed, fabricated, and delivered to the U.S. Air Force, Wright-Patterson Air Force Base, Ohio where it will undergo extensive laboratory testing to establish the feasibility of using the molecular sieve pressure swing adsorption technology to provide fuel tank inerting protection for large fixed wing aircraft. In preliminary testing prior to delivery the developed system met performance goals and predictions. (Author)
