Drone propellers are rotating wings producing lift in the direction of the axis of rotation.
Propeller blade design is critical to generate enough thrust to carry the takeoff weight and reduce
aerodynamics noise level. In this project, numerical analysis is conducted for the aerodynamics
performance of two propeller designs at the static thrust condition. The first design is based on
the original DJI Spark drone propeller blade and the second design add a winglet to the first
design. 3D CAD models were created in SOLIDWORKS for the computational fluid dynamics
(CFD) analysis. The winglet propeller was found to generate 21% more thrust than the original
propeller without winglets. The flow patterns, including pressure and velocity distributions were
compared for both propeller models.
