An Ejector Air Intake Design Method for a Novel RBCC Rocket Nozzle
Bibliographic record
Abstract
An air intake design methodology for a novel rocket nozzle geometry is presented. The novel rocket nozzle is intended for use in rocket based combined cycle vehicles (RBCC) and thus incorporates openings for air intakes. The intake geometry, which consists of a center body, a cowl, and fairings, is designed to minimize total pressure losses while maximizing mass ∞ow rate through the nozzle openings. Six geometric design parameters are required to fully deflne the intake geometry. A ∞ow analysis, which combines an axisymmetric inviscid panel method and an integral boundary layer method, is used to predict the air intake performance based on mass ∞ow rate. Initial comparisons between the ∞ow analysis and 3D numerical simulations show mass ∞ow rate predictions within 4.72% of the 3D numerical simulations.

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; a candidate call from one teacher head, not a consensus.
