POST STALL AIRFOIL BEHAVIOR

[mohr]

Hi
Can anyone tell me any reference about of how to estimate a post stall airfoil behavior. I am studying propeller airfoils
section working in static condition (V=0) and at high angle of
attack (over normal stall angle ).

Any help will be very welcome

Cheers

Mohr

Hello Mohr,

The book, Ducted Fan Design, which also has notes on propeller design, recommends designs for propellers such that the operating point is below 80% of the stalling angle.

I do not know of any book or publication that has post stall airfoil behavior.

This topic is studied (at least) in two fields:

http://naca.larc.nasa.gov

the NACA technical report server may have something for you...

http://www.ecn.nl/library/reports/2001e/rx01004.html

Lots of research is also done on wind turbines (the above is just one example of many...)

Other places to look are at Sandia National Labs, and the NREL ("National Renewable Energy Laboratory"? can't remember the exact acronym)
