Abstract
The research aims to study the uneven distribution of airflow created by a fan over the cleaning system of a combine harvester, affecting the efficiency of the technological process of separating impurities from the original crop. The article presents a methodology for studying the actual operation process using a digital twin, reveals problem areas and studies even distribution of the airflow at the outlet of the fan discharge channel of the combine harvester cleaning system. During the research, several parameters were defined. Based on the digital twin development and study, the airflow rate at the outlet of the radial fan discharge duct of the combine harvester (CH) cleaning system at different rotation rates of the fan wheel (450-1050 min-1) was determined. Experimental measurements of the airflow distribution over the working part of the sieve shoe for the existing cleaning system and modern combine harvesters made up 3.75-10.2 m/s.

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
