For the flat plate air rudder model， under the conditions of Mach number of 10 and unit Reynolds number of 2.1×106/m in the shock wind tunnel， the regulation of hypersonic flow field and the law of heat flux reduction by actively ejecting gas were experimentally studied using schlieren and heat flux sensors. The shock wave structure of the flow field and the heat flux on the model surface were obtained under the conditions of actively ejecting gas at different Mach numbers and pressures. The experimental data show that the interference heat flux of the flat plate and the air rudder can be reduced by actively ejecting the air flow field upstream of the air rudder； when the Mach number of the ejected gas is 2， the heat flux reduction effect reaches 45%， and when the Mach number of the ejected gas is 4， the heat flux reduction effect reaches more than 70%； with the increase of the Mach number and pressure of the ejected gas， the better the heat flux reduction effect of the flat plate， rudder tip， rudder surface and rudder shaft below the ejected nozzle is， and the amplitude and area of the heat flux reduction will increase； by increasing the pressure of the ejected gas， the flow field control effect of the ejected gas at low Mach number is the same as that of the ejected gas at high Mach number； the change of the boundary layer flow pattern and thickness caused by the active injection of gas is the main control factor to determine the heat flux reduction effect of the flat air rudder； in the hypersonic flow field， the ejected gas at a lower Mach number can change the flow pattern downstream， but only the ejected gas at a higher Mach number or pressure can produce a better heat flux reduction effect downstream； from the point of view of gas flow demand， it is suggested to adopt the ejector outlet parameters of “high Mach number， low pressure” for the design of the ejector system.
