Investigation of Aerodynamic Characteristics of Blended-Wing-Body Aircraft Based on Cluster System

Abstract

The aerodynamic characteristics of the BWB-UAVwere simulated numerically based on the High PerformanceComputing Cluster System. The effects on the aerodynamiccharacteristics of the whole aircraft made by the BWB wereinvestigated. 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 wingbody 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.
