Sensitivity analysis of wing aeroelastic responses
… In this study, flutter characteristic of a typical section in subsonic compressible flow is examined using a state-space unsteady aerodynamic representation. The sensitivity of the flutter speed of the typical section with respect to its mass and stiffness parameters, namely, mass ratio, …

Transonic flutter prediction and aeroelastic tailoring for next-generation transport aircraft
… low-order unsteady flow model is coupled to a typical-section structural model (for airfoils) or a beam model (for wings) to accurately predict utter of airfoils and wings. The method is fast enough to permit incorporation of transonic utter constraints in conceptual aircraft design …

Reduced-order aerodynamic models for aeroelastic control of turbomachines
… plunging motion, and coupled to a simple typical section structural model. Stability and forced response of the rotor to an inlet ow disturbance are computed and compared to results obtained using a constant coefficient model similar to those currently used in practice. Mistuning of this …

Investigation of composite façade mullions
Modern curtain wall systems are typically designed with extruded aluminium members. As a load bearing vertical element of the curtain wall system, mullions are also made of aluminium extrusions with glass fibre reinforced polyamide acting as a thermal break joining the external and internal …

Adaptive Control of an Aeroelastic System for Active Flutter Suppression and Disturbance Rejection
… for a two-dimensional pitch-plunge-flap airfoil section with nonlinear torsional stiffness, first- and second-order actuator dynamics, and actuator freeplay. This system utilizes quasi-steady aerodynamic forcing to develop an open-loop flutter model upon which direct model reference adaptive …
