Research on the fuel tank flammability exposure assessment method based on domestic fuel

摘要

The fuel tank explosion is a serious threat to aviation safety. Therefore, the federal aviation administration put forward the concept of Fleet Average Flammability Exposure (FAFE) and quantitative evaluation method after long-term research. The concept and method have been written into airworthiness terms. At present, China civil aviation administration has issued similar regulations in reference to the international standard. Never the less, there are few basic research efforts in the related field. In this paper, the fuel tank flammability exposure evaluation revised method based on domestic fuel is established from existing methods and principles combined with the difference between RP-3 and Jet A. Then the revised method is compared with original method, and the advantage of revised method is shown. At the same time, the relationship between flammability and equilibrium temperature is analyzed, and the optimization method is put forward.
