An Experimental Study of Dynamic Stall on Advanced Airfoil Sections

L. W. Carr, Océane Lambert, Sabina Pucci, Kenneth W. McAlister, William James McCroskey

Abstract

Detailed unsteady boundary layer measurements are presented for eight airfoils oscillated in pitch through the dynamic stall regime. The present report (the third of three volumes) describes the techniques developed for analysis and evaluation of the hot film and hot wire signals, offers some interpretation of the results, and tabulates all the cases in which flow reversal has been recorded.
