抄録

Tokai University and King Abdulaziz University(KAU) in Kingdom of Saudi Arabia has developed a solar powered unmanned aerial vehicle(UAV) under the collaborative project between the universities. In this study, in order to obtain the detail aerodynamic data of main wing, the wind tunnel tests of the three-dimensional wing model, which is based on the same airfoil, SD7037, as the actual main wing of our solar UAV, was performed by using the low speed wind tunnel in Tokai University and its aerodynamic characteristics such as lift coefficient and drag coefficient were obtained. From the results, it was cleared that the roughness is effective to control the boundary layer on the surface of the wing and the aerodynamic characteristics were improved by attaching the roughness using the carborundum, which are two types of size, #100 and #1000.
