Researches of new rapid transport system “Aerotrain” using natural energy resources are conducted. In addition, 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 of the Aerotrain which runs with 2 persons at the speed of 200km/h. The Aerotrain flies close to the ground to get high lift/drag ratio of the wing and to save the driving power. The wing in the ground effect has inevitably has a pitching instability. Therefore, there are the unsteady aerodynamic characteristics such as lift, drag and moment coefficients which depend on the height of the wing above the ground and the incident angle. Aileron flaps are used to fly the Aerotrain stably. Therefore, we need to know the information of aerodynamic characteristics for the aerofoil with aileron flap in the ground effects. In this thesis, we simulated the flows around the aerofoil with aileron flap using thermo-fluid numerical analysis software FLUENT. As a result, we got the velocity and pressure distributions in the flow fields, and the aerodynamic characteristic of the aerofoil available to control the Aerotrain.
