Measured and Predicted Dynamic Response Characteristics of a Flexible Airplane to Elevator Control over a Frequency Range Including Three Structural Modes

Note presenting the longitudinal frequency response of a large flexible swept-wing airplane as determined from its measured response to elevator pulses over the operating Mach number range at a range of altitudes. Response quantities for the nose, center of gravity, wing tip, and tail are shown for frequencies from the airplane short-period mode to the fuselage first-bending mode.
