The invention discloses an aerodynamic heat protection device and a hypersonic aircraft, which can provide an efficient and flexible solution for the serious aerodynamic heat problem in a shock wave interference area, can cope with a complex aerodynamic heat environment in a near space, and does not generate extra additional resistance when not in use. The pneumatic thermal protection device comprises a micro-jet orifice plate provided with micro-jet holes distributed in rows, the micro-jet holes are arranged to spray cooling airflow to incoming flow, and the direction of the sprayed cooling airflow and the direction of the incoming flow form a right angle or an acute angle. The microjet orifice plate is arranged on the upstream side of a shock wave interference area formed by mutual interference of shock waves of the hypersonic aircraft and an incoming flow boundary layer in the incoming flow direction. The pressure stabilizing cavity is communicated with the micro jet hole row; the air supply device is connected with the pressure stabilizing cavity; and the measurement and control module is connected with the air supply device and is set to detect the working condition information and control the start, stop and working parameters of the air supply device according to the working condition information so as to adjust the parameters of the micro-jet sprayed by the micro-jet hole.
