2. Wind turbine design - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine_design

   An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub

3. Tip-speed ratio - Wikipedia

   en.wikipedia.org/wiki/Tip-speed_ratio

   The power coefficient, , expresses what fraction of the power in the wind is being extracted by the wind turbine. It is generally assumed to be a function of both tip-speed ratio and pitch angle. Below is a plot of the variation of the power coefficient with variations in the tip-speed ratio when the pitch is held constant:

4. QBlade - Wikipedia

   en.wikipedia.org/wiki/QBlade

   QBlade is a public source wind turbine calculation software, distributed under the Academic Public License. The software is seamlessly integrated into XFOIL , an airfoil design and analysis tool. The purpose of this software is the design and aerodynamic simulation of wind turbine blades.

5. Wind energy software - Wikipedia

   en.wikipedia.org/wiki/Wind_energy_software

   Germanischer Lloyd found FAST suitable for "the calculation of onshore wind turbine loads for design and certification." [3] [4] The open source software QBlade developed by the wind energy research group of Hermann Föttinger Institute of TU Berlin (Chair of Fluid Dynamics) is a BEM code coupled with the airfoil simulation code XFOIL.

6. IEC 61400 - Wikipedia

   en.wikipedia.org/wiki/IEC_61400

   IEC 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested, [ 1 ] assembled and operated.

7. Blade solidity - Wikipedia

   en.wikipedia.org/wiki/Blade_solidity

   Blade solidity is an important design parameter for the axial flow impeller and is defined as the ratio of blade chord length to spacing. Airfoil nomenclature. Blade Solidity = c/s; Where = / is the spacing; is the mean radius; is blade number

8. Betz's law - Wikipedia

   en.wikipedia.org/wiki/Betz's_law

   According to Betz's law, no wind turbine of any mechanism can capture more than 16/27 (59.3%) of the kinetic energy in wind. The factor 16/27 (0.593) is known as Betz's coefficient. Practical utility-scale wind turbines achieve at peak 75–80% of the Betz limit. [2] [3] The Betz limit is based on an open-disk actuator.

9. Wind-turbine aerodynamics - Wikipedia

   en.wikipedia.org/wiki/Wind-turbine_aerodynamics

   Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
