Abstract :
The aerodynamic characteristics of the BWB-UAV were simulated numerically based on the high performance computing cluster system. The effects on the aerodynamic characteristics of the whole aircraft made by the BWB were investigated. The longitudinal/lateral characteristics of BWB and the conventional tailless sweep wing had been compared. The results showed that BWB configuration had the better longitudinal aerodynamic characteristics. The causes of its excellent characteristics can be attributed to the new wing body lifting design, which can improve the flowing pattern of the surface. But its lateral stability was bad. Therefore, it would be an important criterion that trying to enhance the lateral stability in BWB-UAV design.
