Estimation of the damping derivative in pitch for a wedge at supersonic Mach numbers using design of experiments

This work primarily focuses on numerically modeling the damping derivative over the 2D wedge at different pivot points for considerable values of Mach number and incidence angles. The damping derivative is numerically simulated using regression model analysis. The two-dimensional piston theory of Gh...
