Relevant journal article "Numerical Investigation of the Effect of Leading-Edge Tubercles on Propeller Performance" Read More: https://arc.aiaa.org/doi/10.2514/1.C034845 Relevant publication: http://www.iaeng.org/publication/WCE2018/WCE2018_pp586-595.pdf An aviation propeller with leading edge tubercles Re-upload from https://grabcad.com/library/10x4-7-propeller-with-leading-edge-tubercles-1). Research paper abstract and results: https://3dimensionaldesigningandmanufacturing.blogspot.com/2016/12/numerical-analysis-of-tubercle-effect.html AND https://3dimensionaldesigningandmanufacturing.blogspot.com/2017/08/propeler-with-leading-edge-tubercles.html Diameter: 255 mm Produces ~10% more thrust and is 8% lighter than a baseline propeller. Overall efficiency gain 10% This means direct fuel saving and greener flights. For same diameter it can lift more weight or the propeller can be designed smaller in diameter compared to the baseline propeller for the same thrust. The modified propeller has a larger coefficient of thrust than the baseline propeller. Profile from: 10x4.7 Propeller (mine has different aero foil) Same aerodynamic principles apply to my other entries in aerodynamics, with entirely different areas of application: Energy and power (https://grabcad.com/library/modified-helical-darrieus-wind-turbine-blade-1) Rotary Flight (https://grabcad.com/library/modified-rotor-blade-1) Wings: (https://grabcad.com/library/rear-wing-formula-one-dimensions-2) I have no access to a 3D printer, but propellers can be 3D printed, I have seen people printing them with 3D pens let alone 3D printers and then using them on drones, in YouTube video.
