A method of de-icing blades of a wind turbine comprising a first step of de-icing a blade, a second step of testing whether there is a mass imbalance in the rotor or not and a last step of de-icing other blades of the rotor when a mass imbalance is detected. Also wind turbines ...
The blades of a wind turbine have the most important job of any wind turbine component; they must capture the wind and convert it into useable mechanical energy. The objective of this work is to determine the mechanical power of single big C-section of vertical wind turbine for wind car in...
Next, the equations of the motion for the ice-fragment are solved by means of numerical calculation. The variation of the scatter-domain for the tangent of blade, that for the height of the wind-turbine, and that for the size of the ice are obtained. The fall-density of the ice-...
When the wind blows, the blades of the wind turbine ___. A. stop B. break C. turn D. fall 相关知识点: 试题来源: 解析 C。中文解析:文中说“When the wind blows, the blades of the wind turbine start to turn.”,所以答案是 C。反馈 收藏 ...

From 2000 to 2018, the average length of wind turbine blades more than doubled. Newer models are expected to reach lengths exceeding 85 meters by 2025. Some offshore turbines could be sweeping the sky in the near future with blades 110 meters long—a rotational diameter of two football pitch...
[题目]我会译1.A wind turbine has blades.2.The blades turn in the wind to drive a generator to make electricity.3.Fuels are rich in energy.4.Fuels come from the remains of dead plants and animals
aTo determine the control structures and possible power quality issues, the dynamic torque generated by the blades of a wind turbine must be represented. This paper presents an analytical formulation of the generated aerodynamic torque of a three-bladed wind turbine including the effects of wind shea...
