Will Blade Check Airfoil Per Pwa 330

[scott bean]

Does anybody know if blade will check an airfoil per PWA330 airfoil specification?

Thanks

Hi Scott,
The answer is yes. The best fit method used in Pratt's PWA330 spec is the same as "2 point" best fit used in Blade.

PWA 330 defines both Airfoil SETUP and analysis as "best-fit". In order to create the stacking axis (cmm coordinate system) you must equalize material condition at the Airfoil setup sections defined on the B/P. How can you inspect the setup sections with a "coordinate" measuring machine, if you don't have coordinates to start with? How do you know the cmm is on the correct A/F section line when you collect the data to use for equalizing the setup?

Anyone care to comment?
