With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 “Optimising Design for Inspection” (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work. EH devices based on the usage of kinetic energy, thermal gradients, solar radiation, airflow, and other viable energy sources, proposed so far in the literature, are thus described with a critical review of the respective specific power levels, of their potential placement on airplanes, as well as the consequently necessary power management architectures. The guidelines provided for the selection of the most appropriate EH and power management technologies create the preconditions to develop a new class of autonomous sensor nodes for the in-process, non-destructive SHM of airplane components.

能量收集技术用于飞机部件结构健康监测—综述

为了提高飞机的维护和燃油使用效率，人们日益期望并要求对关键复合结构进行结构健康监测（SHM）。在欧盟COST行动CA18203“优化检查设计”（ODIN）的框架内，需要大量工作来对此概念进行优化使用。在这种情况下，对广泛的能量收集（EH）技术进行了全面的回顾，这些技术有可能用作所考虑的SHM系统的声发射和导波传播传感器以及各自的数据阐述和无线技术的电源通讯模块，在此工作中提供。迄今为止在文献中提出的基于动能，热梯度，太阳辐射，气流和其他可行能源使用的EH设备，因此，通过对各个特定功率水平，它们在飞机上的潜在位置以及随之而来的必要的电源管理体系结构的严格审查来描述它们。提供了用于选择最合适的EH和电源管理技术的指南，为开发用于飞机部件的过程中无损SHM的新型自主传感器节点创造了前提。
