Composite wind turbine rotor blade and method for making same
Patent
·
OSTI ID:5168509
This paper discusses a wind turbine blade including NASA LS(1)-04xx airfoil sections. It comprises a thickness-to-chord ratio of substantially sixteen percent at full radius, the thickness-to-chord ratio increasing to substantially nineteen percent at one half full radius and substantially twenty nine percent at three-tenths full radius; and a twist equal to zero from full radius to fifty percent full radius. The twist varies to a value no greater than eight degrees at a theoretical hub of the rotor blade.
