The shortcomings of the flying-wing aircraft in terms of flight stability and handling performance are as prominent as its advantages in aerodynamics, stealth performance and fuselage space. How to control its shortcomings and give full play to its advantages is the purpose of this paper. In this paper, the application of the control allocation method in the rudder control of flying-wing aircraft with large aspect ratio is studied. An approximate linearization model of rudder effect was established according to each rudder effect to realize the linear control and allocation of rudder. Three linear allocation methods, namely the display combination method, the pseudo-inverse method and the reallocation pseudo-inverse method, are simulated and compared, respectively. When the actuator fails, the control distribution is automatically reconstructed by using the processing method of control allocation reconstruction, so that the flight control system still has a good control effect on the flying wing layout aircraft when the actuator fails.
