Abstract
A blade for a partial pitch wind turbine is described, wherein the blade has a truncated aerodynamic profile provided at the pitch junction of the blade. The truncated trailing edge acts to prevent the formation of a trailing edge gap during pitching between the trailing edges of the inner and outer blade sections of a partial pitch blade, thereby reducing the negative impact of air leakage, etc., when pitching a partial pitch blade.
