Parametric 4 digit NACA Aircraft Propeller Model
grabcad
Generate just about any type of mathematically perfect base model prop using 4 digit NACA numbers. Props can be used for models, for 3D printing, for CNC work, for stress analysis, and for fluid dynamics simulations. Props are intended for aerodynamic applications, but as my demo STL files show, may also be useful for hydrodynamic environments. The 2 bladed and 3 bladed demos have additional modelling done to smooth up the mathematically generated model. The 4 bladed and 5 bladed demos are very close to "as generated." Sorry - but only Autodesk Inventor 2022 is supported. I will continue working on documentation as I finish my "research paper" this is for.
With this file you will be able to print Parametric 4 digit NACA Aircraft Propeller Model with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Parametric 4 digit NACA Aircraft Propeller Model.
