Abstract
Heat exchanger is a core component in aircraft engine bleed air temperature regulation systems. A potential fault associated with heat exchanger is fouling, which reduces the heat transfer efficiency and introduces additional resistance to flow, causing extra drag and fuel consumption. This article presents a heat exchanger fouling detection method based on the valve control command of an engine bleed air temperature regulation system. Heat exchanger fouling is monitored by estimating the deviation of valve control command using an extended Kalman filter. Computer simulations and experiments on a simulated bleed air temperature regulation system have been conducted and the results have confirmed the effectiveness of the proposed method.

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
