Numerical simulation of a quadrotor blade based on structure effect at static thrust conditions

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. ۳D CAD models were created in SOLIDWORKS for the computational fluid dynamics (CFD) analysis. The winglet propeller was found to generate ۲۱% more thrust than the original propeller without winglets. The flow patterns, including pressure and velocity distributions were compared for both propeller models.
