Modern multi-megawatt wind turbines are composed of slender, flexible, and lightly damped
blades and towers. These components exhibit high susceptibility to wind-induced vibrations …

Distributed electric propulsion is a key enabling technology for on-demand electric aircraft
concepts. NASA's X-57 Maxwell X-plane is a demonstrator for this technology, and it …

Wind turbine rotor blades are designed and certified according to the current IEC
(2012)(International Electrotechnical Commission) and DNV GL AS (2015)(Det Norske …

A new nonlinear beam theory is proposed for the analysis of composite wind turbine blades.
The beam theory is developed by extending classical Euler–Bernoulli beam theory to a …

A typical approach to optimize wind turbine blades separates the airfoil shape design from
the blade planform design. This approach is sequential, where the airfoils along the blade …

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 …

The traditional engineering approach to analyse and design turbines for energy extraction is
based on decoupling the hydrodynamics from the structural design. Whereas this approach …

Wake effects in wind farms can cause significant power losses. In order to reduce these
losses layout and control optimization can be applied. For this purpose, simple and fast …

The current diminution of fossil-fuel reserves, stricter environmental guidelines and the
world's ever-growing energy needs have directed to the deployment of alternative …

Desalination of seawater from renewable energy sources is without doubt an appealing
solution to face water scarcity issues in coastal areas. In particular, tidal energy technologies …
