Abstract: Abstract In this chapter we make a precise mathematical statement of the aeroelastic problem that we wish to solve. Having described the structure model, we turn to the air flow model simplifying it to the most used case where we neglect viscosity and consider “nonviscous flow” but more importantly assume that the entropy is constant. This makes the flow vortex free so that the flow can be described in terms of the potential. Our concern is again more the structure response in air flow—“aeroelasticity”—and hence the fluid–structure boundary conditions play the dominant role in determining the aerodynamic loading on the wing structure.
