本文分析了在无粘不可压缩流中，柔性翼在大振幅弯曲路径上运动所产生的水动力。大振幅振荡推进的参数研究，特别强调弦向柔性的鳍的效果，提出。与刚性翼片的类似运动相比，这种灵活性可使推进效率提高2%，同时使总推力略有下降。
The hydrodynamic forces due to the motion of a flexible foil in a large amplitude curved path in an inviscid incompressible flow are analysed. A parametric study of large amplitude oscillatory propulsion, with special emphasis on the effect of chordwise flexibility of the fin, is presented. This flexibility was found to increase the propulsive efficiency by up to 2% while causing small decreases in the overall thrust, compared with similar motion with rigid foils.
