给出了计算弹性支承扑翼发电机多翼叶栅结构功率和效率的解析和数值方法。分析方法基于二维线性位势气动理论，数值方法基于二维N-S方程。将这两种方法应用于水轮发电机双翼和三翼结构的同相振荡和反相振荡，分析了振荡方式和翼距对系统功率和效率的影响。对于邻翼距离为2.0-2.5弦长的反相振荡模式，引入十翼构型预计的功率增量约为25%-33%，与单翼产生的简单功率总和相比。
The analytical and numerical methods for estimating power and efficiency of a multi-wing cascade configuration of an elastically supported flapping wing power generator are presented. The analytical method is based on the 2D linear potential aerodynamic theory and the numerical method is based on 2D Navier-Stokes equations. Both methods are applied to the twoand three-wing configurations of a hydroelectric power generator oscillating in in-phase and anti-phase modes of oscillation, and the effects of the oscillation mode and wing distance on the power and efficiency of the system are clarified. The power increment expected by introducing the ten-wing configuration is estimated to be approximately 25–33% for the anti-phase mode of oscillation with the adjacent wing distance of 2.0–2.5 chord lengths compared with the simple sum of power generated by a single wing.
