Abstract : Results of unsteady linear and full potential theory are used for analysis of wings and aircraft configurations. In particular the details of unsteady pressure distributions at the trailing edge are investigated aiming at better representation of control surface hinge moments. The importance of viscous effects are observed and a comparison between potential theory and Navier-Stokes predictions is made.
