Abstract
[Abstract] In this paper, a new formulation for a ground dynamics model of a commercial two-engine helicopter is validated after touchdown. The inputs of the ground dynamics model are the velocities and angles at touchdown, and its outputs are the forces and moments produced by the ground on the helicopter. Expressions for forces and moments, which depend on the ground contact force, the friction coefficient between the skids and the ground, and the system stiffness and damping are determined. . The system stiffness and damping are defined between the touchdown point and the center of gravity in each of the helicopter’s degree of freedom. Expressions for the stiffness, damping and friction coefficients are validated for two kinds of landing situations: one-engine inoperative and autorotation. The ground dynamics of the Bell-427 helicopter model are then used to build and certify a level-D flight simulator.

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
