TL;DR: In this paper, the authors defined the pitch-moment coefficient as the ratio of pitch moment to pitch moment, and used it to measure the pitch moment of a chord chord.

TL;DR: The effects of dynamic stall on airfoils oscillating in pitch were investigated by experimentally determining the viscous and inviscid characteristics of the airflow on the NACA 0012 airfoil and on several leading-edge modifications as mentioned in this paper.

TL;DR: In this paper, the dynamic stall characteristics of eight airfoils have been investigated in sinusoidal pitch oscillations over a wide range of two-dimensional unsteady flow conditions.

TL;DR: In this article, the effect of compressibility on dynamic stall behavior has been comprehensively studied, including a review of work performed on both aircraft and helicopters, and offers insight into the impact of compressible airfoils on the complex aerodynamic phenomenon known as dynamic stall.

TL;DR: In this article, the authors describe the techniques developed for analysis and evaluation of the hot film and hot wire signals, offer some interpretation of the results, and tabulate all the cases in which flow reversal has been recorded.
