从风或水流中提取能量通常通过旋转系统来实现。然而，人们认识到（并且已经证明）振荡翼也可以用于此目的。介绍了一种新研制的展翼式风力发电机。利用二维纳维尔-斯托克斯模拟研究了它从潮汐流和高空急流发电的潜力。一个NACA 0014机翼发电机进行非正弦俯仰运动的结果表明，在功率和效率方面，比正弦运动增加了30%。
The extraction of energy from wind or water streams is generally accomplished by means of rotary systems. However, it is recognized (and it has been demonstrated) that oscillating wings can also be used for this purpose. A newly developed oscillating-wing windand hydropower generator is described. Its potential for the generation of electric power from tidal flows and high-altitude jet streams is studied using 2D Navier-Stokes simulations. Results for a single NACA0014 wing power generator undergoing non-sinusoidal pitchplunge motion indicates a 30% increase in power both power generated and efficiency over that for sinusoidal motion.
