Oxygen Dilution Requirements for Inerting Aircraft Fuel Tanks.
Proc 2nd Conf on Fuel Systems Fire Safety 1970 May; :85-117
The effectiveness of various inerting agents to prevent ignition and flame propagation in hydrocarbon fuel-air systems is briefly reviewed. Data are presented on the variation of limits of flammability, minimum ignition energies, and minimum autoignition temperatures with oxidant or diluent concentration. For inerting aircraft fuel tanks containing jet a or jet b type fuels at 100 deg. F, it is recommended that the oxygen concentration be maintained below 10 volume-percent with nitrogen as the inert and below 12.5 Volume-percent with carbon dioxide as the inert. An expression for calculating the oxygen dilution requirements at various temperatures is also given in this paper.
