Airfoils selection for a Blended Wing Body aircraft in medium Reynolds number

The objective of this study is to identify suitable aerodynamic airfoils for a blended wing body unmanned aerial vehicle operating at medium Reynolds numbers. To achieve this objective, a weighted scoring method was employed to choose among 32 airfoils documented in existing literature that meet the requirements for a blended wing body mini UAV. The aerodynamic properties of the selected airfoils at the aircraft level were then compared. A multi-fidelity analysis tool, XFLR5, was utilized to determine these aerodynamic attributes and trim characteristics during level flight.
