Abstract

Today the BWB configuration aircrafts are considered as a revolution in aerodynamic design. However, many challenges have been facedby scientists and researchers. These may be the occurrence of the flow separation in two areas of the blended wing and body region, and the outer region of the wing. In this paper, the effect of MVGs on the aerodynamic performance of a basic model of a typical BWB-UAV has been researched.The investigation was experimentally carried out at a speed of 18 m / s with varying angle of attack. In this work, the coefficients of lift, drag and pitching moment were measured and the effect of MVGs in different situations, were compared.The most important outcome of these experiments was enhancing L/D ratio in the presence of MVG on the model surface.
