I found tutorial for symmetrical equation curve for NACA Airfouil in Inventor 2013. http://www.youtube.com/watch?v=zKSBe9hImTE
I need to create assymentric airfoil. I am wondering if there is a possibility to put equation in Inventor which looks like the one I attached in doc file.
If it is not possible that's OK as I can use coordinate generator in the internet and put coordinates into inventor so I can draw it but It would be nice to put set of the equations rather than manually put 100 points.
I know that those equations are more complicated and I don't know how to start with them in Inventor
Solved! Go to Solution.
Solved! by PiotrekL1. See the answer in context.
I will follow your advise. I will generate coordinates in the NACA tool and put then through MS Excel into inventor
Thank you very much
I'm not in front of Inventor right now, so can't check the syntax for the equation curve editor - but I would say "yes", this is possible. For now, I'd just recommend inserting points from Excel. Inventor will draw a spline through the imported points for you - it's like the poor-mans Equation curve editor! Have a look at the expanded tool-tip for the format of the Excel sheet. (It's on the Sketch > Insert panel.)
Been working on this to...
My end goal is to have an assembly with n number of NACA 4 digit (and others) profiles. This will allow the user to quickly develop a surface model to export to a CFD program.

Step 1: Developing NACA 4 digit profiles
Approach 1: Sketch Equation Curve
Following equitation on http://en.wikipedia.org/wiki/NACA_airfoil, I was successfully able to develop the mean camber line (with two different equation curves). While trying to add the equations for the top and bottom of the profile, I ran into many issues most of which resolved after time, although not all.
Approach 2: Thickness Circles + mean camber line = Spline (kinda)
Using my sucsessful mean camber line, I added 10 circles along the mean camber line and demendsioned their linear poisiton along the mean cambber line using the x_u parametric equations, and their heigth demension from the x-axis using the y_u parametric equations.
Propossed Approach 1: iRule/iLogic/API
The title is garbled because I don't know enough about each of those, but my preliminary research shows this may be the correct approach. The plan is to create a set of point using the parametric equations to define a spline.
If anyone has any questions/comments/advise please let me know.
