Abstract The mission of high-altitude long-endurance unmanned aerial vehicles is limited by energetic considerations. This paper explores, for the first time in the open literature, statistic estimates of the potential energy that may be harvested from gust encounters along a representative flight mission. The work is built around three objectives: (1) investigate the influence that the configuration of the piezoelectric inserts, at equivalent total mass, has on the energy harvesting performance; (2) assess the energetic balance between the harvested energy from gust encounters and the energy needed by an actuation system to achieve a certain gust load alleviation; and (3) discuss the potential weight saving of batteries when employing piezoelectric inserts. The test case is for the flexible wing of a high aspect ratio unmanned air vehicle flying at low speeds.

从具有统计代表性的阵风遭遇中收集气动弹性能量

摘要 高空长航时无人机的任务受到能量考虑的限制。本文首次在公开文献中探讨了可能从一次具有代表性的飞行任务中遭遇阵风中获取的势能的统计估计。这项工作围绕三个目标展开：(1) 研究压电插件的配置在等效总质量下对能量收集性能的影响；(2) 评估从阵风遭遇中获取的能量与致动系统实现特定阵风负荷缓解所需的能量之间的能量平衡；(3) 讨论使用压电插件时电池的潜在重量减轻。
