Abstract
The S-97 RAIDER® helicopter uses a pusher propeller to provide forward and reverse thrust capability to Sikorsky's X2 Technology™ design. Due to the propeller's aft mounting location on the aircraft it experiences aerodynamic interactions with both the airframe wake and main rotor wake across the flight envelope. This paper details the inclusion of an aerodynamic interference flow field near the propulsor disk plane in a CSD (Computational Structural Dynamics) propulsor model used to predict blade loads. The interference flow field uses either wind tunnel measurement or CFD (Computational Fluid Dynamics) to define the aerodynamic flow near the propeller plane. The predicted blade loads were compared with flight test data at a variety of steady flight conditions and overall good agreement is found between simulation and test. The simulation methodology is also expanded to simulate transient hover and acceleration conditions using a quasi-steady trim approach at multiple discrete time points of the maneuver. Overall good correlation of the measured blade maximum, minimum, and vibratory loads are achieved.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
