Hello,
I am looking for disc geometry/parametric model for Rotor 67 or 37 for vibration analysis.

If somenbody has it please let me know.

Best regards,

Hey

I think these are for rotor 67 (page 18)
http://ntrs.nasa.gov/archive/nasa/ca...1990001929.pdf

But do you know how to interpret the data?

If I just key in these coordinates for each section in the cylindrical system, do you think it will generate the rotor shape for that section?

And what is TNPC, Beta, Beta1 and Beta2?

Also there is this other person (t_shirt) who has typed coordinates for the rotor in a spreadsheet
