The enhancement of high altitude drone endurance compels to design very flexible high-aspect-ratio composite airframe vulnerable to destructive fluid/structure interaction like flutter or torsional divergence. Extensive research has been conducted to increase critical speed without being at the expense of weight balance. One of the promising solutions is the aeroelastic tailoring which consists in a specific configuration of laminated composite layup. The present work uses an aeroelastic reduced order model, namely GEBTAero, suitable for the non linear anisotropic behavior of this kind of composite wing, able to quickly compute aeroelastic critical speeds. Particular focus is put on a wind tunnel test campaign conducted on a set of flexible plates, both metallic and composite, in order to assess the accuracy of GEBTAero.
