“…The performed analyses confirm, in any case, that, under the given geometrical conditions, the specific power requirement could be fulfilled on the module-level, and TEGs might therefore be used to at least support the conventional generator. An autonomous SHM system based on crack sensor is, in turn, described in [156]. In this case, the power is supplied by using a dynamic TEG harvester at temperatures of up to 200 °C with Eythritol as the phase change material (PCM).…”

“…A concept of a backup TEG for aeronautic applications was then tested on a proof-of-concept technology demonstrator on a small airplane turboshaft engine TS100 (Figure 23). It was thus shown that the backup electrical power source, based on a MEMS TEG module with suitable power management, power conditioning and energy storage elements, might be used only in the failure state of onboard power lines of the aircraft, providing the needed electrical An autonomous SHM system based on crack sensor is, in turn, described in [156].

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.

“…A study has shown how much waste heat generated by the engine nearby the aft pylon that caused its environment temperature to rise by 200℃. The maximum temperature of 580℃ can be detected at its outer surface and minimum of 350℃ can be detected at inner surface [2]. Yet, the temperature farther than the engine is cooler and the difference in temperature can be fully utilized by using Stirling engine to produce sufficient energy for avionics systems or simple mechanical action in aircraft.…”

A conceptual design of Stirling engine suitable for onboard aircraft application is the motivation behind this study. The aim is to evaluate the suitability of the system to be integrated in aircraft as part of energy contributor by recycling the waste thermal energy. A parametric evaluation of an established Wobble-Yoke Stirling Engine state space model was performed to determine a suitable pre-compensator design that is able to produce the highest power output given the size and mass constraint. Simulation was performed using MATLAB in order to analyze the dynamic properties of the engine as a closed-loop system, with temperature, pressure and damping coefficient acting as controlling parameters. The parametric evaluation was conducted to determine the effect of assemble mass of piston, maximum displacement of piston and viscous damping coefficient to the performance of the system. The methodology can be used in the conceptual design process in order to determine the sizing and power output of the stirling engine system.

“…PCMs can provide a stable power generation environment for thermoelectric materials [21,22]. The research of this kind of power generation structure has appeared, such as high-temperature power generation on aircraft, power supply of underwater glider [23], and airborne sensor [24,25]. PCMs can be used on the hot side of thermoelectric power generation (TEG) to reduce the temperature change [26], and it is necessary to improve the thermal conductivity of PCMs [27,28].…”

The existing thermoelectric materials are greatly affected by the temperature environment, which can provide better power output in a stable temperature environment by using composite phase change material with enhanced heat conduction. The graphene is dispersed in the liquid mannitol to make the nanomixed material. Test results show that the thermal conductivity of mannitol increased from 0.7 Wm-1 K-1 to 2.07 Wm-1 K-1, 179.73% times as much. The effective thermal conductivity of mannitol can be increased to 8.4236 Wm-1 K-1 by using a graphite foam with a porosity of 0.9. After adding 1 wt.% and 5 wt.% graphene particles, the effective thermal conductivity increased to 8.73 Wm-1 K-1 and 9.63 Wm-1 K-1, respectively. The simulation results in a large heat source environment show that mannitol with improved thermal conductivity can ensure the stable operation of the thermoelectric material in the optimal temperature environment for 120 s, and the open-circuit voltage is maintained at about 6.5 V in that time.
