Abstract
View Video Presentation: https://doi.org/10.2514/6.2022-2129.vid A critical part of the store separation analysis is the modeling of the ejector forces. Typically, such loading is included into separation simulation via a table look-up of the ejector forces either as a function of time or stroke of the ejector pistons. The values of the ejector forces are generally obtained by curve fitting experimental static ejection test data. Depending on the fidelity of the model, it may or may not consider the mass of the store in the force history, and such models virtually never consider the moments of inertia of the store or the aerodynamic loading at the time of ejection. This paper develops a model based on the physics of the flow within the ejector to account for the creation of ejector gases, losses in the system, and appropriate physical feedback of the store mass properties, aircraft loading, and the aerodynamics.

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.
