“…The wing is made of composite material, and the trailing edges are able to morph and, by doing so, to increase or decrease the camber, thus replacing conventional ailerons. The reader is referred to the related previous works for details on the wing design [27] and its investigation with FSI tools [19].…”

The paper proposes a novel approach to data-driven reduced-order modeling which combines the Dynamic Mode Decomposition technique with the concept of balanced realization. The information on the system comes from input, state, and output trajectories, and the goal is to derive a linear low-dimensional input-output model approximation. Since the dynamics of aerospace systems markedly changes when some parameters are varied, it is desirable to capture this feature in the system's description. Therefore, a Linear Parameter-Varying representation made of a collection of state-consistent linear time-invariant reduced-order models is sought. The main technical novelty of the proposed algorithm consists of replacing the orthogonal projection onto the POD modes, typical of Dynamic Mode Decomposition techniques, with a balancing oblique projection. The advantages are that the input-output information in the lower-dimensional representation is maximized, and that a parameter-varying projection is possible while also achieving state-consistency. The validity of the proposed approach is demonstrated on a morphing wing for airborne wind energy applications by comparing its prediction capabilities with those of a recent algorithm from the literature.

“…The flutter speed of the system was much higher than the maximum speed planned for the tests. Fasel et al [134] presented the numerical modeling and optimization of a camber morphing Airborne Wind Energy (AWE) aircraft. The work focused on modeling the reduced-order coupled flight dynamics and aeroelasticity of the aircraft using Matlab Simulink.…”

“…After experimental validation, it was determined that the FSI model tends to under-predict lift coefficients and trailing edge displacements, and they suggest that a mesh refinement in both FEM and CFD models may improve results. Finally, Fasel et al [31] also implements a 3D CFD and 3D FEM FSI analysis to model the aeroservoelasticity of a morphing airplane for energy harvesting.…”

This paper presents a newly developed three-dimensional Fluid-Structure Interaction (FSI) routine for the Fish Bone Active Camber (FishBAC) concept that couples a three-dimensional Lifting-Line theory analysis to a two-dimensional viscous corrected panel method (XFOIL) to create a viscous corrected three-dimensional wing aerodynamic solver. This aerodynamic model is then coupled to a previously developed multi-component Mindlin-Reissner plate model based composite analysis routine for the FishBAC morphing device. The methodology is explained, and predictions are validated against existing modeling tools. The FSI model developed in this paper shows good agreement when compared against other structural, aerodynamic and FSI tools. Additionally, results show the FishBAC's ability to improve aerodynamic performance at a wide range of operating conditions.
