The fuel dispersion and initiation of single-event FAE (SEFAE) is self-harmonious. The very short delay-time between fuel dispersion and initiation is adverse to make good use of the oxygen in atmosphere for detonation of SEFAE. Therefore,experimental study on single-event FAE were made with adding solid oxidizer to the fuel (KClO₄,NH₄ClO₄) to improve the power of SEFAE. The results show that (1) the oxygen in fuel clouds zone is abundant to oxidize the fuel of SEFAE completely,whereas,for the original solid multi-component fuel mixture,the oxygen in atmosphere is not utilized effectively,and the energy of SEFAE do not release thoroughly; (2) adding NH₄ClO₄ to the original solid multi-component fuel mixture improves the power and stability of SEFAE,and the optimum content of NH₄ClO₄ in this kind single-event FAE is 15%.
