摘要：

The characteristics of engine-jet interference are highly significant for the design of symmetric reusable vehicles. A jet experiment under the condition of subsonic/transonic flight was performed in the wind tunnel FD-12 at China Academy of Aerospace Aerodynamics. This experiment used the normal temperature compressed air as the high temperature fuel gas of the engine-jet. Similar parameters of the experiment include geometry dimensions of the vehicle, flight Mach number of the vehicle, Mach number of the exit on the engine nozzle, and the static pressure ratio of the engine nozzle exit to the faraway inflow. Experimental results show that the engine-jet effect on the aerodynamic characteristics of the vehicle and the hinge moment of the body flap varies with the Mach number of inflow, the deflection angle of the nozzle, and the body flap. © 2021, Beihang University Aerospace Knowledge Press.
