Abstract

A partial pitch wind turbine blade is described wherein a stall fence is provided at the partial pitch junction of the blade. The stall fence provides for the separation of the airflow between the inner blade extender section and the outer blade section, and fur therrnore can be used to seal the gap at the pitch system junction between the two blade sections.
