Wind Tunnel Testing for the SB>1 Defiant Joint Multi-Role Technology Demonstrator
Bibliographic record
Abstract
Wind tunnel tests have been conducted to support development of the SB>1 DEFIANT™ Joint Multi-Role Technology Demonstrator. The objective is to provide data to validate and enhance the aerodynamic performance and flight dynamics models and to improve understanding of the aerodynamics of X2 TECHNOLOGY™ configurations. The first model was a 1/11 scale airframe with a powered propeller that was tested in the United Technologies Research Center (UTRC) Pilot Wind Tunnel (PWT) in 2013-2014. The second model was a 1/5 scale airframe with a powered coaxial main rotor that was tested at the U.S. Air Force National Full Scale Aerodynamic Complex (NFAC) in 2016. This model could also be tested with a powered propeller. Measurements included forces and moments on the various components, as well as fuselage, empennage, and blade surface pressures. For the 1/11 model, fuselage-induced flow fields at the propeller and empennage locations were also measured. Application of the experimental results to the State Space GenHel flight dynamics model is described.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
