In this paper, a small category surveillance-type fuselage-wing combination of a Blended Wing Body (BWB) UAV and a conventional Tube-wing UAV were designed. The designs were created using MATLAB code and modeled in Open VSP and Solid Works. The Aerodynamic analysis was carried out (excluding the Propellers) using Open VSP and ANSYS Fluent. The fuselage-wing configuration of UAVs was studied to determine the impact of the integrated role of the fuselage, wing attachment, and shape on Aerodynamic performance. Then, the results of the two UAV models obtained from Open VSP and Ansys Fluent were compared. Findings from this study indicate that the coefficient of lift at various Angle of attack (AOA) is higher for the Tube-wing UAV, even when the tail was excluded. However, when the Aerodynamic efficiency is considered, the BWB UAV outperforms its counterpart. Furthermore, the moment coefficient of the BWB UAV has a negative slope, indicating stability. In contrast, the Tube-wing UAV has a positive slope (unstable) for the moment coefficient, which necessitates the attachment of the tail section for stability. Thus, further decreasing the Aerodynamic efficiency of the Tube-wing UAV. Additionally, it is also found that at lower AOA, the Open VSP and CFD results show close agreement. Thus, it can be concluded that the BWB UAV design remains more Aerodynamically efficient than the conventional Tube-wing Design despite the tail being excluded.
