Electric Aviation - NASA interview on Maxwell X57 - Part 2: Propeller Design

Parts in the NASA interview series: - Part 1 - New aerodynamic concepts: https://youtu.be/m4rysu8LlLM - Part 2 - Propeller design: https://youtu.be/UDZBqDQGU8o - Part 3 - Battery and component cooling: https://youtu.be/ieB541felas - Part 4 - Electric flight experience: https://youtu.be/pGn07UTVKBg In this second video in our series with NASA, we dive into the details of the propellers and how they compare to other propellers seen on e-VTOLs for example. The X57 features two very distinct propellers: - High lift propellers: these increase the local airflow speed around the wing, providing it with more lift. They aim for a uniform flow velocity to create a predictable and reliable increase in lift. - Cruise propellers: these are aimed at maximum efficiency and feature a higher axial flow speed at the tips of the propellers ----------------------------------------------------------------------------------------------------------- The AirShaper videos cover the basics of aerodynamics (aerodynamic drag, drag & lift coefficients, boundary layer theory, flow separation, reynolds number...), simulation aspects (computational fluid dynamics, CFD meshing, ...) and aerodynamic testing (wind tunnel testing, flow visualization, ...). We then use those basics to explain the aerodynamics of (race) cars (aerodynamic efficiency of electric vehicles, aerodynamic drag, downforce, aero maps, formula one aerodynamics, ...), drones and airplanes (propellers, airfoils, electric aviation, eVTOLS, ...), motorcycles (wind buffeting, motogp aerodynamics, ...) and more!
