Forward Curved Centrifugal Fans

Dear all,

Where or how can a I get the ideal profile for the blades of a forward curved multivane impeller?

As far as I have seen, the blades are made with an arc profile. I think it is because of manufacturing reasons(sheetmetal)

I would like to make a study for the fabrication of a plastic impeller(PP, PA ...). Therefore, I could make any profile improving the efficiency.

Do you know where I can find a study of the optimal blade profile? which is the ideal shape?

Thank you very much in advance!
