NACA 2300 series stall behavior at low R numbers
NACA 2300 series stall behavior at low R numbers
(OP)
I note that the lift curve has a rather sharp break-off for this series of airfoils. I have a book published in the 1940's that indicates a gradual stall at lower Reynolds numbers but which does not give actual lift curves, pitching moment curves, etc. for low Reynold's numbers.
Does anyone have airfoil data for these foils at Reynold's numbers for around 30 mph stall speed and 60" wing chord?
Other low R number information for use at low light aircraft speeds would be useful too. I know of the UIUC site but that is for very low R number's typically for RC models and UAV's.
I would be looking at a 15% thick section tapering to 9 or 12%.

Wind turbine aero tests usually need the post-stall region because blade stall is a common way to regulate RPM in high wind speed.
Good luck. If you find anything, please leave a note here because I like digging up this stuff, too.

Sorry I am to late with any useful reply. Thr NACA TR 586
"AIRF. SECTION CHARACTERISTICS AS AFFECTED BY ...." It contains 23012 data from RN 172.000 to 3.170.000.
Cheers
