Abstract
This paper proposes a modeling approach for the nonlinear dynamics simulation of airships. The flight mechanics, aerostatics, and aerodynamics are incorporated into the model. A comprehensive estimation method is provided for the aerodynamics, including added-mass terms, viscous effect, forces on the fins, forces on the hull due to the fins, and axial drag. A simulation program is developed from the dynamics model and applied to analyze the control responses of the Skyship-500 airship. A comparison between the simulation and flight test results for different control inputs shows that the dynamics simulation gives a reasonable estimation of the flight behavior. The dynamics model is then linearized using a finite difference approach and the linear model is applied to investigate the stability of longitudinal and lateral motion at various speeds. With the trust gained from validation, the dynamics model and simulation program can be used to evaluate the flight and control performance of other airships.

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
