Kurzfassung deutsch:
tThis paper describes the performance improvement of an energy harvesting device for aircraft by increas-ing its operational temperature range. The thermoelectric energy harvesting device consists of twocavities each containing a different phase change material, acting as thermal mass. Thermoelectric gen-erator elements (TEGs) are attached to the inner part of the fuselage and to the thermal mass. Therefore,an artificially enhanced temperature difference between the bottom and the top surface of the TEGs iscreated during take-off and landing. Different temperature profiles mimicking short/mid-range Euro-pean flights are investigated. The performance in terms of efficiency, power-to-weight ratio and energyharvested is studied in detail, both by simulations and experimental data.
