Airfoils for wind turbines have been selected by comparing data from
different wind tunnels, tested under different conditions. This makes
it difficult to make accurate comparisons. Most wind tunnel data sets
do not contain airfoil performance in stall, which is commonly
experienced by turbines operating in the field. Wind turbines are often
roughened by soiling, for which there is very little data. Finally, recent
tests have shown that dynamic stall is a common occurrence for most
wind turbines operating in yawed, stalled, or turbulent conditions.
Little dynamic stall data exists for the airfoils of interest to a wind
turbine designer. In summary, very little airfoil performance data exits
that is appropriate for wind turbine design.
Recognizing the need for a wind turbine airfoil performance data base,
Special care has been taken to report as much of the test conditions
