Hypersonic speed combined resistance and heat reducing structure based on reverse jet flow and active cooling

The invention discloses a hypersonic speed combined resistance and heat reduction structure based on reverse jet flow and active cooling, and belongs to the technical field of resistance and heat reduction. Nozzles are arranged at the passivated leading edge of the aircraft, and reverse jet flow is implemented. And the nozzles are symmetrically arranged up and down relative to the center line of the passivated leading edge of the aircraft in a matrix form. A convection cooling loop, a gas jet loop and an internal supporting space are arranged in the airplane passivated leading edge. The convection cooling loops are arranged on the upper surface and the lower surface of the passivation front edge respectively, the cross section of a flow channel, close to one end of a nozzle, of each convection cooling loop is in a step shape, and cooling media circulate in the convection cooling loops through pumps. One end of each gas jet loop is connected with the nozzle, the other end of each gas jet loop is connected with
