Keywords: Propeller, Propulsion, UAV, Ducted Fan, Efficiency, AcousticsThe full process of custom propeller design and testing for efficiency and acoustics is described. Physics-based design tools are utilized in the design process, such as computational fluid dynamics (blade element momentum theory and Navier-Stokes solver) and high-fidelity structural analysis (finite element analysis). Testing for propeller efficiency and acoustics is carried out in controlled environment. Testing apparatus are carefully calibrated prior to data recording to ensure accurate results. The final deliverable is a custom propeller design(s) for improved vehicle performance.
