摘要：Based on the description of the operating principle of a green on-board inert gas generation system (GOBIGGS), which could decrease the oxygen volume fraction on ullage of a fuel tank via the injection of the inerting gas produced by a catalytic combustion reactor, a GOBIGGS flow was designed and its mathematical model was setup. GOBISGGS was compared with the on-board inert gas generation system (OBIGGS) in which the inerting process was realized via the injection of the nitrogen enriched air (NEA) separated by a hollow finer membrane module. The result reveals that if the flow rate of the exhaust gas from the fuel tank in GOBIGGS is identical with that of NEA in OBIGGS, the inerting effect of GOBIGGS is much more positive than that of OBIGGS. Additionally, the performance GOBIGGS affected by the efficiency of the catalytic combustion reactor and the allocation proportion of the preheating gas were investigated. It is found that the increase of the efficiency could shorten the inerting time to the maximum safe oxygen volume fraction and reduce the ultimate oxygen volume fraction, and the power consumption of the system could decrease if a proper allocation proportion of the preheating gas is chosen. © 2017, Editorial Department of Journal of Aerospace Power.
