Abstract
In this study, an integrated hydrogen fuelled energy system is developed, analysed and assessed thermodynamically through energy and exergy efficiencies. A LH2 fuelled solid oxide fuel cells (SOFC) is developed to provide electrical and potable or toilets water usage of aircraft, and heat recovery for wings icing prevention is combined with the system and the unchanged hydrogen from SOFC burns in a combustor to drive the aircraft refrigeration cycle, after SOFC stream is recovered for steam bottoming cycle, also integrated hydrogen fuelled jet engine provides thrust for aircraft. This paper includes energetic and exergetic performance assessment studies of the hydrogen SOFC and aircraft thrust engine systems. The proposed integrated systems have overall energy and exergy efficiency values of 24.68% and 22.45%, respectively.

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
