What this dataset tests
Whether a system can model a healthy airframe vibration spectrum as a coupled-mode manifold.
It must return: a coherence index a coupling graph a drift envelope phase-conditioned baselines.
Required outputs
- manifold_coherence_index
- baseline_mode_coupling_graph
- expected_mode_drift_envelope
- phase_conditioned_baselines
- baseline_confidence
Scoring conventions
- indices range 0 to 1
- drift envelope uses frequency and coupling tolerances
- coupling graph summarizes strongest cross-sensor links
- baselines vary by flight phase
Use case
Layer one of Structural Health as a Vibration Mode Manifold.
Supports:
- fleet health baselining
- later fault localization via topology distortion
- separating phase effects from true damage signatures
