| Research Abstract |
When an airfoil moves close to a ground, it interferes strongly with the ground through the fluid viscosity. In order to reconstruct the circumstances the airfoil moves relative to the ground, the circulating disc apparatus was used. The aerodynamic characteristics ; lift, drag coefficients and the ground pressure distributions along the wing direction were measured. Numerical simulations of the fluid flows around the airfoil were also carried. After the numerical accuracy was confirmed, the details of the characteristics of the airfoil were clarified. Then, the aerodynamic characteristics of the three dimensional wing of AEROTRAIN in ground effects was elucidated.
