The Wing Typical Section

This chapter introduces the wing typical section, which is the basic two-dimensional model for the study of phenomena of aeronautical interest. It is considered in the context of the development and solution of aeroelastic models of varying accuracy and complexity, aimed at stability and response analyses. Steady, quasi-steady and unsteady formulations for airfoil aerodynamics are outlined and applied, with the theories of TheodorsenTheodorsen theory, WagnerWagner theory and Küssner-SchwartzKüssner-Schwartz theory included among them. Methodologies for aeroelastic modelling in state-space form are illustrated, and the problem of gust response is examined.
