As global warming continues to increase, countries around the world are developing new energy sources to reduce carbon dioxide emissions. However, most new energy sources are less compatible with existing industrial systems. Especially in the field of aviation, it is difficult to rapidly apply emerging new energy technologies due to the lack of validation. The new aviation fuel is a new energy source similar to the traditional aviation fuel. On the one hand, it can reduce carbon dioxide emissions, and on the other hand, it has good compatibility with existing aviation equipment. Therefore, it has a greater potential for rapid popularization. The existing validation method of new aviation fuels is mainly based on the standard system of the American Society for Testing and Materials (ASTM), and the core is based on the operational experience of traditional aviation fuels to constrain the physicochemical properties of new aviation fuels, which can give a clear range of physicochemical properties before validation. Recently, some scholars believe that it is possible to improve the adequacy of the safety assessment of new aviation fuels from the perspective of safety analysis of aviation engines, but it is difficult to give a clear range of physicochemical properties before the assessment in this way, which is not conducive to the reference of research and development organizations. In this paper, we propose a method to obtain the safety boundaries of new aviation fuels by inverse mapping through Monte Carlo method using a standard engine model with fuel resolution. It not only provides support for the range of physicochemical properties of the ASTM standard, but also improves the reference of the new safety assessment method.
