中文摘要：

一个新想法拖减小，为极超音速的车辆的热保护为吃惊重建基于物理尖铁和侧面的喷气的联合被建议。尖铁在钝身体前面重做鞠躬吃惊进圆锥形的震动，和侧面的喷气工作保护尖铁尖端免受过热的伤害并且当一个投球的角度在飞行期间存在时，推圆锥形的吃惊离开钝身体。实验在 6 的一个名字的马赫数字在一条极超音速的风隧道被进行。钝身体上的吃惊 / 吃惊相互作用由于注射被避免，在附件点的山峰压力被 70% 在 4 °攻击角度下面减少，这被表明。

英文摘要：

A new idea of drag reduction and thermal protection for hypersonic vehicles is proposed based on the combination of a physical spike and lateral jets for shockreconstruction. The spike recasts the bow shock in front of a blunt body into a conical shock, and the lateral jets work to protect the spike tip from overheating and to push the conical shock away from the blunt body when a pitching angle exists during flight. Experiments are conducted in a hypersonic wind tunnel at a nominal Mach number of 6. It is demonstrated that the shock/shock interaction on the blunt body is avoided due to injection and the peak pressure at the reattachment point is reduced by 70% under a 4° attack angle.
