Abstract
In this paper, a reduced control-centric model of a particular behavior associated with maritime helicopter rotor systems, known as Blade Sailing Phenomenon (BSP), is developed. BSP is a transient aeroelastic phenomenon described by the large undesired flapping motion of the helicopter rotor blades during low rotor speeds. The developed model utilizes the Unified Airloads Model to capture the aerodynamic loads, the Intrinsic Nonlinear Beam Model to capture the structural behavior of the blade, and the Integrally Actuated Twist (IAT) for actuation. The governing partial-differential equations of motion together with the blade structural displacements as the output of interest are then discretized in the space domain using the Galerkin Spectral Discretization Method. The resultant nonlinear ordinary-differential equations are in the standard form of nonlinear systems that is highly desirable for designing a feedback controller to counter the BSP.

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
