Abstract:

Nitrogen fuel tank inerting has been shown to be an effective means of providing aircraft explosion prevention by reducing the O2 concentration below the lower limit for fuel vapor ignition. A program for the feasibility study and laboratory demonstration of fuel tank inerting by nitrogen generation was conducted. Typical system requirements have been defined using the McDonnell Douglas DC-10 as a transport aircraft representative of potential applications. The study concluded that both the catalytic combustion of air with turbine engine fuels and air separation by hollow fiber permeable membranes are viable candidates. A preliminary design for a DC-10 system based on hollow fiber permeable membranes has been established. Data from laboratory testing demonstrate system operation as an inert gas generator and good compliance with performance predictions.
