A thermobaric explosive containing aluminum powder shaped flake and many physic-chemical parameters′ testing courses of the fuel were mainly introduced. The energy contained in fuel was calculated,the energy releasing efficiency of fuel was tested in different environment,and the fireball′s expanding characteristic and shockwave′s removing process were studied. The results show that the fuel′s energy density is 16.11 MJ·kg^－１ theoretically,about 4 times of TNT-equivalency. The energy releasing rate of the aluminum flakes in the fuel is fast,and the released energy enhances the shockwave immediately when the shockwave is born and spreads. The fuel is safe in using and depositing. The capacity of the fuel′s anti-loading is identified well after impact test and shooting test in large caliber fire-guns,and also show that the fuel is safe under the overload by 1.7×10⁵ m·s^－2. The fuel′s stability is adopt to the large caliber fire-guns′ shooting condition.
