The carrier-based aircraft is faced with severe working environment,so it is necessary to avoid the damage of personnel and equipment by high-temperature wake flow, but also to reduce the intake port of high-temperature gas to prevent the engine thrust reduction and surge. In this paper, the accuracy of the numerical simulation analysis is verified by the test data at first. Then, the flow mechanism and temperature field characteristics of a certain type of carrier-based aircraft with twin engine jet impinging on the deflector are analyzed; the dynamic flow characteristics of high temperature gas inhaled by the inlet and total temperature rise rate are also obtained. Finally, the risk of high temperature gas inhaled by the inlet is evaluated under asymmetrical engine flows, different wind flows, and different distances from the nozzle tail to the jet blast deflector. It is concluded that the distance from the nozzle tail to the jet blast deflector plays a decisive role in the overall strength and distribution of the backflow field, and that the position of the inlet affects the coupling characteristics of the suction and backflow field.
