Summary

The equations of motion for an elastically-supported airfoil are first derived. This is followed by a extensive review of the classical results of linear unsteady aerodynamics. State-space realizations are then introduced for those solutions, which result in time-domain formulations in dynamic aeroelasticity. They are used to introduce basic aeroelastic concepts, including flutter, divergence, and response to discrete gusts and continuous turbulence.
