Abstract: The requirements of air-breathing aerospace engines for fuels from the aspect of energy density， heat sink， ignition and combustion were analyzed. Then the technical routes to improve the performance of fuels were summarized， including synthesizing new liquid hydrocarbons and adding energetic nanoparticles to increase the energy density of fuel， modifying the molecular structure of fuels and applying additives and/or catalytic reactions to promote the heat sink， and designing and synthesizing chemically active fuel molecules and utilizing highly active additives to improve the combustion efficiency. Finally the fuels to satisfy the development of future air-breathing engines were suggested， including high-energy-density fuel with energy of 60MJ/L， fuels with heat sink to endure flight at speed of 5～6 Mach ( for long time)， 7～8 Mach and 9 Mach respectively， and fuels for pre-cooling combined power engines.

Key words: Air-breathing aerospace engines；High energy density fuel；Synthetic fuel；High heat-sink fuel；Flammable fuel
