Recently, researches of a new rapid transport system “Aerotrain” using natural energy resources have been continued, as one of approaches to various global environmental problems. In order to put the Aerotrain into practical use, to improve running stability is one of the research assignments. The Aerotrain which has vertical side wings at each tip of main wings arranged in tandem is able to get high lift-to-drag ratio and save the driving power by ground effects between the main wing and ground, and between the side wings and sidewalls. However, the wing in ground effect has inevitably a pitching instability, because the unsteady aerodynamic characteristics such as lift, drag and moment coefficients depend on the height of the wing above the ground. Hence, it is difficult to get the self-stability only airframe configuration for the Aerotrain. For this reason, the aileron-flaps are used to run the Aerotrain stably. In this paper, we simulated the flows around the wing of the 3rd model (ART003) with aileron-flaps using thermo-fluid numerical analysis software FLUENT. As a result, we clarified the aerodynamic characteristics of the ART003 wing with aileron-flaps, and got the aerodynamic characteristics of the wing available to control the posture of the Aerotrain.
