It deals with 2or 3-dimensional geometries, resolves frequencies up to a spatio-temporal Nyquist limit de\ufb01ned by the wake discretization, and has a convenient form for linearization, model reduction and coupling with structural dynamics models. No assumptions are made relating to the kinematics of the \ufb02uid-structure interface (inputs) and use of Joukowski\u2019s theorem to compute forces naturally resolves all components of the unsteady aerodynamic forcing (outputs). Linearized expressions are written about arbitrary non-zero reference geometries, velocities and loading distributions and as such yield models that are as general as possible given the assumptions in the underlying \ufb02uid mechanics. The implementation is veri\ufb01ed against classical solutions in the unsteady aerodynamics, and in aeroelastic stability analysis of cantilever wing con\ufb01gurations.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-150.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Rafael Palacios, Robert J.
