Abstract
The electrification of aircraft propulsive systems has been identified as one of the potential solutions towards a lower carbon footprint in the aviation industry. However, there are still several environmental and technological challenges associated with the propulsion electrification. One of these challenges is the development of adequate thermal management systems that are lightweight and can cope with the higher heat loads estimated for all-electric and hybrid-electric aircraft when compared with conventional architectures. Addressing this latter issue is therefore an operational requirement for more electric aircraft. There are several solutions proposed in the literature to tackle this challenge at different levels of development. The main focus of the current paper is to provide a critical review on the existing solutions. From this review, liquid cooling loops integrated with ram air heat exchangers seem to be the most viable ones with nowadays technology. However, in the future the introduction of nanofluids with higher thermal conductivities and skin heat exchangers can be an interesting solution to improve performance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
