- Abstract
Aircraft flying in formation in wingtip vortices influence to the lift coefficient decreases, resistance coefficient increases, lift to drag ratio decreases sharply, the stall angle of attack decreases. Correctly reflect the aircraft wing flow field around the basic information, and to reveal the variations in these performance parameters of aircraft control the extent of the impact of performance is used numerical method for aerodynamic characteristics of the aircraft and the manipulation of analysis based. In the influence of wingtip vortex numerical computing, along with the change of eddy current range, intensity, machine interference flow distribution will also change, need repeated calculation for the flow around the new changes, numerical simulation process calculation workload is huge. In this paper, based on the thorough study of Western Europe and the United States to solve the low speed viscous flow N-S equation, a set of methods based on improved SIMPLE numerical model is proposed to solve the N-S equation. This method takes into account the viscous effect of the flow field in the flight process, and has a high numerical model to solve the velocity. The results of numerical simulation of the flow field are obtained.
