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. Since 2008, these researches have been supported by NEDO (New Energy and Industrial Technology Development Organization). The purpose of this project is to develop the 3rd model (ART003) of the Aerotrain which runs at the speed of 200km/h. In order to put the Aerotrain into practical use, to improve lift-to-drag ratio 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, it needs to increase lift-to-drag ratio for mass transportation. In this paper, we simulated the flows around the wing of ART003 using thermo-fluid numerical analysis software FLUENT. As a result, we clarified the aerodynamic characteristics of the ART003 wing, and were able to suggest the wing models which got higher lift-to-drag ratio.
