Determination of angle of attack for rotating blades
Journal Title: INCAS BULLETIN - Year 2012, Vol 4, Issue 2
Abstract
For a rotating blade the flow passing by a blade section is bended due to the rotation and the local flow field is influenced by the bound circulation on the blade. As a further complication, 3-D effects from tip and root vortices do a precise definition of the angle of attack (AOA) a difficult task. Two methods for determining the AOA on rotating blade from velocity and pressure measurements are presented.
