dc.description.abstract1/20 scale wind tunnel tests are performed about one configuration at 8 different flow conditions and numerical analysis are performed for eight different shapes. In order to study effect of Reynolds number and ground simulation on the experimental results, 4 wind speeds and tangential blowing technique at grow1d are chosen for the experiments. By measuring surface pressures, the effects of the Reynolds number variation and the ground simulation is presented. Solutions of 3 dimensional Navier-Stokes equations are obtained using FDS for the spatial discretization and AF-ADI for the time integration. Current computational results are verified with the experimental results, and after the numerical analysis of the eight different cases, it is shown that the dependency of the pressure drag on existence of skirt, sectional shape and nose length is clarified.-
