Abstract

Influence of aircraft wingtip vortices will make the lift coefficient of formation flying wingman decreases, the drag coefficient increases, the lift drag ratio decreased sharply, attack decreased the stall angle of attack. To correctly reflect the basic information around the airfoil flow field of aircraft, and reveal the influence degree of these performance parameters on the control performance of aircraft, a numerical method is adopted in this paper to analyze the aerodynamic characteristics and maneuverability of aircraft. Based on the in-depth study of the N-S equation of low speed viscous flow in Western Europe and the United States, a method based on the improved simple numerical model for solving the N-S equation is proposed. The method takes into account the viscous effect of the flow field during the flight, and obtains the numerical simulation results of the flow field.
