摘要：
There are difficulties in yaw control of a flying⁃wing aircraft due to the cancellation of vertical tail.A variety of control schemes were designed based on the jet flow control technology to assist in and optimize the yaw control.The jet control actuator was designed and manufactured.Through the wind tunnel force measurement experiment and two⁃dimensional numerical simulation, the control effect and mechanism of each scheme were analyzed, and the optimal control scheme was selected.The results showed that under the same jet momentum coefficient, it was easier to obtain yaw moment by producing resistance than by applying thrust.After turning on the excitation, the more inverse components the jet contains in relation to the incoming flow, the more obvious the interaction with the incoming flow;the larger the separation zone formed, the better the control effect.The forward symmetric blowing was proved to be the optimal control scheme, which can produce about rudder effect equivalent to a split drag rudder deflection of 70°, and the coupling degree of moment was small. © 2021, Editorial Department of Journal of Aerospace Power.
