Abstract

Mounting a spike on the front end of hypersonic vehicles is an effective way to reduce vehicle drag. It is characterized by its simple structure, good drag reduction and some thermal protection. However, the thermal protection capability of the spike alone cannot meet the thermal protection requirements of hypersonic vehicles. Transpiration cooling is an effective active thermal protection method with strong cooling capacity, small amount of coolant and high system stability. Therefore, in this paper, we propose a new joint drag-reduction thermal protection configuration-spike-transpiration cooling configuration. It is used to address the problem of high thermal flux at the shock attachment point to a spike configuration. The spike configuration, the transpiration cooling configuration, and the spike-transpiration cooling configuration have been simulated numerically by solving the N-S equation, and their drag-reduction and heat-resistance properties have been analyzed. It is shown that the spike-transpiration cooling configuration is more drag-reducing and heat-protective than the single configuration when the length-diameter ratio is longer.
