High Efficiency Electric Propulsion Design and Testing

This whitepaper outlines the design process and presents verification testing of an electric ducted fan for small UAV integration. Flight time estimation is made from performance testing results and vehicle weight estimations and compared with (not limited to) the DJI Phantom 4, which has a similar rotor span as the designed duct. The use of 3D printing allows for quick turnaround and acquisition of test data while simultaneously lowering costs significantly. The described process points to the potential of either increasing the payload or the flight time or both, depending on how the vehicle is configured.
