This study focuses on the effect of a weak jet of a porous plate on the aerodynamic heating of high-speed vehicles. By using a variable nozzle to form different weak air jets through a uniformly distributed porous plate in a shock tunnel, the heat flux distribution on the surface of the porous plate near the ejection area under different Mach numbers, attack angles, and jet velocities is studied. The main results show that the uniformly distributed pore structure increases the wall roughness and promotes transition during heating, the jet velocity has a remarkable impact on the heat transfer characteristics of the plate, and the heat flux on the plate as well as the cooling effect increase with the attack angle.
