Since the aerotrain utilizes the ground effect, researches of the aerofoil section which can harnesses the ground effect effectively are important. The aerotrain moves along U-shaped guide way which has a ground and side walls, so it has many viscous interference elements. We analyze the flow through a primary and secondary aerofoils, to prevent the boundary layer separation for the improvement of the aerodynamic characteristics at low speed and near the ground. A small secondary aerofoil is equipped above the trailing edge to increase lift at takeoff and landing. We find out the most suitable location of secondary aerofoil by the boundary layer approximation analysis, and experiment using towing wind tunnel at the Sunrise-Beach Research Facility in Miyazaki., 資料番号: AA0063908015, レポート番号: JAXA-SP-07-026E}, pages = {47--50}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Experiments at the Sunrise-Beach Research Facility of the aerodynamic characteristics on ground effects of aerofoils with a secondary aerofoil}, volume = {JAXA-SP-07-026E}, year = {2008} }
