Experimental investigation was conducted of effect of pitching rate and pitching axis location on aerodynamic loading of two-dimensional airfoil during nonoscillatory pitching motion to large angle of attack; selected test results, believed to be applicable to helicopter blade experiencing dynamic stall, are presented; rate of change of angle of attack is established as dominant factor determining very large peak lift and moment acting on airfoil during stall process.
