This is just a useful tip to consider when calculating the Performance Coefficient CP of Horizontal Axis Wind Turbine HAWT that a lot of people don't take in consideration.
This tip I introduced in our wind turbine graduation project in 2010 which was "Helical Savonius wind turbine". This point will reduce the CP value declared by HAWTs manufacturers as they calculate based on the swept area, while the rectangular area is the real area occupied by the turbine. This rectangular area can be more useful in VAWTs.
