摘要

半主动扑翼是一种附加在扭转弹簧上的垂动翼,它能有效地产生推力。本文采用边界元法研究了这类箔的推进特性。通过数值研究阐明了箔片惯性和共振的影响。结果表明,扑翼推进器在各种工况下都是高效的。尽管惯性不同,但峰值效率大约发生在相同的提前数,并且对应于相同的俯仰幅度。本研究也支持浸入式共振与最佳性能相关。另一方面,当结构共振时,所有箔的推进特性是相同的,而不考虑箔的惯性。有证据表明,在一定的工作条件下,铝箔也可以作为能量收集器。

Influence of resonance on the performance of semi-active flapping propulsor
ABSTRACT A semi-active flapping foil, which is a heaving foil attached to a torsional spring, efficiently generates thrust. In this report, the propulsive characteristics of such foils are studied using a boundary element method. The numerical investigation is performed to clarify the effects of foil inertia and resonance. It is found that the flapping propulsor is efficient over a wide range of operating conditions. The peak efficiencies occur approximately at an identical advance number and also correspond to the same pitch amplitude in spite of different inertia. The present study also supports that the immersed resonance is relevant to the optimal performance. On the other hand, the propulsive characteristics of all foils are identical regardless of foil inertia when structurally resonated. An evidence has been found that the foil can also perform as an energy harvester in a certain range of operating condition.
