A novel catalytic inerting system is designed and its working principle is described in detail. The outflow rates of each gas component passing through the catalytic reactor are derived in which the molar flow rate of suction gas is used as a baseline. A mathematical model to calculate the concentrations of all gas components on ullage of the fuel tank is set up via the mass conservation equations. Three different aviation jet fuels including RP-3, RP-5 and RP-6 are chosen to calculate the variation of the oxygen concentration on ullage under various fuel loads and efficiencies of the catalytic reactor via the given mathematical model. The study reveals that owning to the disparate vapor pressure of the chosen aviation jet fuels, the flow rates of the supplemental air from the atmospheric environment and the produced mixed inerting gas entering into the fuel tank are extremely different. Hence, the difference of the variation of the oxygen concentration on ullage adopting these there jet fuels in the catalytic inerting system is larger than that in the hollow fiber membrane based on-board inert gas generation system. It is suggested that the influence of the type of aviation jet fuels should be considered carefully during the design of a catalytic inerting system.
