At present, the TPS of flight vehicles is designed based on the radiation equilibrium condition. The approach is conservative and is unable to consider the influence of active cooling. In this paper, a TPS design method coupling active cooling of kerosene is developed. Such a method includes the calculation of aerodynamic heat, the design of passive TPS, and the determination of design parameters of active cooling system. A reusable launch vehicle and its typical trajectory is studied. The results show that 33% weight of passive TPS can be reduced by active cooling, and the required product of mass flowrate per area and coolant temperature increase are between 2.1 and 4.9 (K·kg·m-2·s -1 ).
