The results show:For the same wind speed, as the wake away from the windrotor, the wake velocity gradually closer to flow velocity;
计算分析得出，对于同一风速，随着尾流远离风轮，尾流速度逐渐接近来流风速；

The energy in the wind turns two or three propeller-like blades around a rotor.
风力推动固定在转轴上两三个像推进器一样的叶片。

CFRP materials have been available for nearly 50 years and are used in the aviation and aerospace industries, in car racing and, most recently, in rotor blades for wind turbines.
