Effects of Angle of Attack and Airfoil Profile on the Two-dimensional Flutter Derivatives for Airfoils Oscillating in Pitch at High Subsonic Speeds

Report presenting two-dimensional aerodynamic lift and moment flutter derivatives for moderate and high angles of attack for several airfoil profiles varying in thickness and thickness distribution. The results indicate that the variables angle of attack, airfoil profile, reduced frequency, and Mach number all have significant interdependent effects.
