airfoil parametric bulb for rc sailboat by Guillaume_F

Last crawled date: 4 years ago

naca (or any airfoil) parametric bulb with Openscad.
Perfect for 3d printed (lead casting) rc sailboat bulb.
Thingiverse is missing archive or directory upload - not appropriate for openSCAD.
Please take the complete source from my GITHUB: Complete source code. Code > Download ZIP.
This project manages:
symmetric / asymmetric airfoil profile.
complex/custom section - included circle, ellipse, flatten ellipse, round square, trapeze.
beaver tail.
split rendering
How-to:
Download Github ZIP archive
Install OpenSCAD
Decompress the archive
Run openSCAD on bulb.scad
Edit bulb.scad and tweak the header to fit your needs (documentation in the code)
Add new airfoil:
You have complete "ready to use" scad files on my github Airfoil database
Choose one and move it to the directory "airfoil"
Open the scad file to copy the header (copy/paste part) - 4 lines.
Open the bulb.scad to paste the header, replace the previous airfoil with yours.
To reach the right weight:
generate the STL file
get the associated volume in cm3 (DuckDuckGo: "stl volume calculator")
compute your material volume to weight (i.e. lead weight grams per cubic cm: 11.342)
fine tune the scale factor or the form
