Decarbonization requirements have extended the use of wind turbines by orders of
magnitude. Due to their high stiffness-to-weight ratio, composite materials have been widely …

Classical flutter of wind turbine blades is defined as an aeroelastic instability where a
torsional blade mode couples to a flapwise bending mode to result in a mutual rapid growth …

With the progression of novel design, material, and manufacturing technologies, the wind
energy industry has successfully produced larger and larger wind turbine rotor blades while …

Aeroelasticity concerns the interaction between aerodynamics, dynamics, and elasticity. This
interaction can result in negatively or badly damped wind turbine modes, which can have a …

Recent advances in analysis capabilities for wind turbine blade aerodynamics and structural
dynamics enables a thorough understanding of the connection between the aerodynamic …

For wind turbine blades with the increased slenderness ratio, flutter instability may occur at
lower wind and rotational speeds. For long blades, at the flutter condition, relative velocities …

Classical aeroelastic flutter instability historically has not been a driving issue in wind turbine
design. In fact, rarely has this issue even been addressed in the past. Commensurately …

This work presents a new aeroelastic model that governs the extensional, chordwise,
flapwise, and torsional vibrations of an isolated horizontal axis wind turbine blade. The …

The effects of bend-twist coupling on the flutter limits of large composite wind turbine blades
are investigated in this work. A mixed, geometrically exact, and nonlinear finite element for …
