Abstract
Analysis of the frangibility of airport approach lighting towers using both full-scale impact tests and computer simulation were performed to develop a better understanding of the buckling and failure mode of the tower when struck by a representative aircraft. These data were necessary for the development of simplified requirements and test methods for the design of frangible structures that minimize the impact hazard to aircraft. This paper describes the model developed to simulate the impact properties of the tower using the LS-DYNA finite element analysis software. Three different velocities, 50, 80, and 140 km/h were used in combination with two different orientations of the tower to simulate impact at the apex and on the side of the triangular cross section tower. The results obtained using this simulation were compared to the experimental results from full-scale tests. In addition, the tower dynamic behavior was compared to the high-speed video imagery to confirm failure mode predictions.

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
