A semi-analytical model for the combined aeroelastic behaviour and gust response of a flexible aerofoil

Semi-Analytical Reduced-Order Models for the Aeroelastic Behavior of Subsonic Flexible Wings via Generalised Plate and Beam Formulations

“…note that this equation is uncoupled from all others and hence does not affect the aeroelastic stability of the wing, in the present framework of a linear model for small perturbations [10].…”

“…is the induced flow velocity due to aerofoil motion, the generalised coefficients t y v k , of which are readily given by [10,19]:…”

“…Note that a change of variables is always possible as long as a proper transformation matrix can be defined and all aero-structural matrices are then consistently projected onto the new modal base [10,19].…”

“…Efficient aeroelastic methods and tools [1][2] based on reduced-order complexity [3][4][5][6] are increasingly sought for the preliminary multidisciplinary design and optimisation (MDO) [7][8] of flexible subsonic wings [9][10][11][12][13][14]. A semi-analytical model for the aeroelastic behavior of a thin straight wing in unsteady incompressible flow is hence here presented.…”

Composite stacking sequence optimization for aeroelastically tailored forward-swept wings

“…This is of particular interest if aerodynamic considerations beyond that required for the aeroelastic analysis are to be taken into account. However, strip theory allows computationally cheap optimization to be undertaken, especially where the focus of the work is on composite tailoring for the aeroelastic response and preliminary design [15,5,29,30]. The lift is then given by:…”
