The multi-scale flow coupling effects induced by Shock Wave/Boundary Layer Interaction (SWBLI) in hypersonic flows significantly exacerbate the challenges of thermal load management for flight vehicles. A transverse-opposing dual-jet active control scheme for air rudder is proposed, and its impact characteristics on SWBLI and aerothermal environments under complex inflow conditions is revealed. The numerical methods employed are validated against experimental data from open literature, and a grid independence analysis is conducted. Results indicate that the transverse-opposing dual-jet scheme achieves global heat reduction superior to single-jet configurations through spatially coupled configurations. Under the condition of an 11° rudder deflection, positioning the transverse jet further upstream and the opposing jet at a higher elevation constructs a large-scale separation zone that isolates the high-temperature mainstream. Consequently, the peak heat fluxes on the leading edge and the plate are controlled below 3 200 kW·m-2 and 300 kW·m-2, respectively. At an angle of attack of 11°, all dual-jet configurations significantly reduce the gap heat flux to below 300 kW·m-2. However, the leading-edge heat flux is sensitive to jet positioning; it is crucial to ensure the opposing jet remains within the low-pressure wake of the transverse jet to prevent severe flow reattachment and a subsequent surge in heat flux.
