| The aerodynamic heating flux results of the stagnation point and forehead of the two kinds of hypersonic bait bullet models is presented in this article by using the amendatory Lees formula and the amendatory Kemp-Riddell formula. Regarding the ball- column model .After analyzed the gas thermodynamic property behind the shock wave, the results of aerodynamic heating quantity and its the influence factors has been obtained under different heights and speeds .the unitary press and heat flux distribution has been obtained through the amendatory Newton formula and the partial similar solution theory. Regarding ball- cone-column model, then the forehead cone partial heat flux distribution is calculated emphatically. The comparison of the compution results and the results using the J.D Anderson formula predication is made.
