  Full Text
A methodology for the aeroelastic analysis of highly flexible slender structures is presented. The structural model is based on an asymptotic approximation to the displacement field, which separates the problem into a long-scale problem involving geometrically-nonlinear deformations of the reference line and a small-scale problem that captures deformation in the cross section. The combination of them provides a three-dimensional solution to the structural dynamics of flexible vehicles suitable for aeroelastic simulations.
