Composite Star-Beams as Pitch Compliant Tension-Torsion Support Mechanism for Active Windmill Blade Tips. D. Stefan Dancila, ; Jennifer D. Goss, ; Julia Elaine Cline and ; Kwangtae Ha
A wind turbine including a control system and at least one wind turbine blade having a pressure measurement system is disclosed. The pressure measurement system includes a pressure probe that provides a measurement of inflow angle to the control system. The control system adjusts the blade pitch angle of the at least one turbine blade in response to the inflow angle measurement to improve ...
Blade optimization is an area of key focus in the overall effort to bring down LCoE. In this session, it is possible to hear blade innovation initiatives with focus on increasing production output as well as initiatives that aim to solve some of the ongoing challenges for the wind sector: The issues of noise and leading-edge erosion of the blades.

Nevertheless, wind turbine blades represent a challenge due to the type of materials used and their complex composition. There are a number of ways to treat GFRP waste, depending on the intended application. The best available waste treatment technologies in Europe are outlined in this paper. However, there is a lack of practical experiences in ...
Stefan Heinz. Joachim Peinke. ... This work aims at radar sensors in the frequency band from 57 to 64 GHz that can be embedded in wind turbine blades during manufacturing, enabling non ...
Wind Power W is a prominent "green" solution to the global energy crisis. Wind power was the most rapid growing source of usable energy from 1990-2002 in 2003, and its strong growth continues. Currently the majority of wind farms are in European countries and the United States. The global wind power capacity by the end of 2008 had reached a value of over 120.8 GW .
Halve the sound wind turbines make without any energy loss. Placing saw teeth on the blades of wind turbines is now possible. The saw teeth are designed by Stefan Oerlemans of the University of Twente and the National Aerospace Laboratory (NLR). Oerlemans first studied the sounds wind turbines made…
