Passive aeroelastic tailoring of wind turbine blades : a numerical analysis
… approach the ideal blade deformation. However aeroelastic effects, which cause additional deformation, are almost unavoidable in flexible blade design and it is desirable to tailor these effects to our advantage by a controlled use of orthotropic material properties and a smart design of the …

Transonic flutter prediction and aeroelastic tailoring for next-generation transport aircraft
… are more flexible, leading to more potential aeroelastic problems. Furthermore, these aircraft fly in the transonic flow regime, where utter prediction is difficult. The goals for this thesis are to devise a method to reduce the computational burden of including transonic utter constraints in …

Integrated structural design, vibration control, and aeroelastic tailoring by multiobjective optimization
… Constraints on natural frequencies and aeroelastic damping were also considered. Derivatives of the objective and constraint functions with respect to structural and control design variables were derived for a finite element beam model of the structure and constant feedback gains …

Integral aerodynamic-structural-control wing design
… control constraint equations. To suppress the aeroelastic divergence of the forward-swept wing, and to reduce the gross weight of the design aircraft, two separate cases are studied: (1) combined application of aeroelastic tailoring and active controls, (2) aeroelastic tailoring alone. The …

Aeroelastic behaviour of composite wings
… investigations into the structural, dynamic and aeroelastic behaviour of composite wings. The study begins with a literature review where the development of aeroelastic tailoring and specific applications of the technology are discussed in detail. A critique of methods for the determination of …

Vibration and Aeroelasticity of Advanced Aircraft Wings Modeled as Thin-Walled Beams--Dynamics, Stability and Control
… analytical anisotropic thin-walled beam model, aeroelastic instability, dynamic aeroelastic response, active/passive aeroelastic control of advanced aircraft wings modeled as thin-walled beams are systematically addressed. The refined thin-walled beam model is based on an existing framework of …

Optimal Design and Analysis of Bio-inspired, Curvilinearly Stiffened Composite Flexible Wings
… of the aircraft wing, which may cause many aeroelastic problems such as large deflections, increased drag, onset of flutter, loss of control authority, etc. Aeroelastic tailoring, internal structural layout design and aerodynamic wing shape morphing are all considered to address these …

An Efficient Reduced Order Modeling Method for Analyzing Composite Beams Under Aeroelastic Loading
… beneficial stiffness coupling typically used for aeroelastic tailoring. Due to the complexity of modeling composites, designers often select safe, simple geometry and layup schedules for their wing/blade cross-sections. An example of this might be a box-beam made up of 4 laminates, all of which …

Optimization of Harmonically Deforming Thin Airfoils and Membrane Wings for Optimum Thrust and Efficiency
… associated leading edge separation. The complete aeroelastic system for a membrane wing is also optimized. The aerodynamic theory for deformable thin airfoils is used as the forcing in a membrane vibration problem. Due to the nature of the two dimensional theory, the membrane vibration problem is …
