Hi everybody,
For a CFD-simulation i`m modelling the shape of the 1.5 MW turbine in CAD.
In the “Subcontract Report NREL/SR-500-32496” on page 16 is the following sentence written:
- The blade section was circular between the root at 5% … , and then it transformed to the S818 30% airfoil shape …
What does that mean “30 % airfoil shape” ?
Thanks for help.
Regards
