Abstract

fetched live from OpenAlex

The scarfed nozzle is used in engines which can produce reversal thrust,or to produce revolving torque on turbine rocket engines at high speed.Researching for the laval scarfed nozzle,the theoretical calculation on thrusts and their coefficients,thrust angle,torque for the model are made,and their theoretical equations and their dimensionless values with different ψ and θ are achieved.These conclusions with analyses and comparisons will benefit the research on the performance calculations of scarfed nozzle and its initial theoretical design.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
