  • The configuration of flying wing aircraft with large aspect ratio is advantageous on the characteristic of aerodynamics and stealth, but due to lack of conventional elevator and rudder, gust load alleviation control method for the aircraft with conventional configuration is not suitable anymore. The characteristics of representative arrangement of control surfaces on an aircraft with flying wing configuration were discussed; also the specialty with configuration of flying wing in gust alleviation system was analyzed, when applying the method of direct lift force control. To improve a flying wing aircraft-s response to atmospheric turbulence, a control law of the control system was designed, using the method of poles configuration of invariable characteristic structure. At last, both the aircraft-s open-loop and closed-loop responses to atmospheric turbulence were calculated, analyzed and compared; meanwhile, the aircraft-s ride quality was given and compared to some criterion. Results show that the control law given by the method can improve the aircraft response to atmospheric turbulence effectively.
