What is Dynamic Stall in Airfoil Pitching Studies about?

This paper presents wind-tunnel studies on the dynamic stall of an NACA 0015 airfoil pitching at a constant rate, analyzing time-varying pressure data to determine lift and moment coefficients across various conditions. The findings indicate that slower pitch rates significantly delay stall and increase maximum lift coefficients, with nondimensional pitch rates under 0.03 more than doubling the maximum lift coefficient. The study emphasizes the relationship between quarter-chord separation and dynamic stall
