“…In fact, many of the studies in Table 10 present tools/methods that have more than one of these capabilities. Finally, some of the studies are devoted specifically to analysis tools for certain type of aircraft, such as electrified propulsion aircraft [205], [210], [281], [282], or specific types of TMS, such as power and thermal management systems [261] (see also Section 8.4).…”

“…The work of the NASA team of Chapman et al [19] modeled ducted heat exchangers for a light aircraft, but, like the earlier work by Schnulo et al [9], the codebase for this project is not publicly available. Bell and Litt [20] developed thermal models of similar fidelity in the MATLAB/Simulink ecosystem. Byahut and Uranga [21] modeled the propulsion system of an all-electric Twin Otter aircraft considering thermal management weight, including the effect of system voltage and the insulator thickness on the wiring.…”

Thermal Management System Optimization for a Parallel Hybrid Aircraft Considering Mission Fuel Burn

Electrified aircraft propulsion enables new aircraft designs with fewer emissions. One challenge of electrified architectures is handling the electrical components’ waste heat. This is because batteries and other electrical components are sensitive to high temperatures and accumulate heat within their structure. In this work, we investigate using a thermoacoustic refrigerator to cool the battery of a parallel hybrid single-aisle commercial transport aircraft. This thermoacoustic refrigeration system is powered by waste heat from the turbofan engine core, whereas a conventional refrigerator consumes electricity from the battery or shaft power offtakes. Compared to a conventional vapor cycle refrigerator, the thermoacoustic refrigeration system results in greater mission fuel burn because of pressure losses attributable to the extraction of heat from the turbofan to drive the thermoacoustic refrigerator. Heat exchangers with very low pressure losses may render the thermoacoustic refrigeration system beneficial compared to conventional refrigeration in certain use cases, such as low-altitude missions.
