Design Research on a Bionic Anti-drag Propeller
China college students “Internet+” Innovation Competition Project * 📍Ministry of Education 🇨🇳 📅 04/2017-04/2018 👨🏫supervised by Prof. Yangang Wang Idea proposer, poroject manager and key participant of team of 7, in charge of 3D modeling, CFD simulation Catia, Gambit, fluent Abstract In this study, the drag reduction propeller with serrated leading edge is designed based on the bionics principle-the fin of humpback whale. It is divided into 4 steps, CFD simulation of three kinds of straight airfoil, propeller design, propeller strength design, propeller modeling, propeller 3D printing, from the design and selection of the foundation straight airfoil to the design and research of the three-dimensional propeller. In the last step, a simple experimental verification was carried out. Finally, a conclusion is drawn that the standard-sin leading edge airfoil shows a better characteristic line and the bionics propeller possesses a higher proficiency. ...
