N2 - In order to maintain low cruise speeds and high efficiency for unmanned aerial vehicles, low wing loading designs are required. Consequently, the influence of atmospheric turbulence on aerodynamic measurements performed on such vehicles increases, especially on drag. The current study evaluates if it is possible to measure the drag of such medium-sized UAVs in-flight. For this reason, a 7m wingspan, 65kg take-off mass conventional configuration UAV is used. Global, induced as well as component drag (airbrakes, landing gear and flaps) is extracted using the data recorded in-flight with high atmospheric turbulence. The measurements are compared to CFD studies as well as empirical data for the airbrakes.
