Abstract
In order to improve the hot environment that faces missiles launched by concentric canister launcher(CCL),the factors that affect the gas temperature at the outlet of CCL are discussed and the fundamental gasdynamics principle in the process of reducing gas temperature are also analyzed in this paper.And several research works for reducing outlet gas temperature of CCL are analyzed with the energy conservation theory in the paper,several kinds of CCL developed by others are explained in detail about how to reduce gas temperature at the outlet of CCL.Furthermore,a new type,variable crosssection concentric canister launcher,is proposed in the paper.The gap between outer and inter canisters of the launcher is designed to be a convergent-divergent shape similar to the Laval nozzle to enhance the outlet velocity of gas while reduce its temperature.FLUENT software is used to numerically simulate a 2-D convergant-divergent type CCL.The simulation results show that the convergant-divergent type CCL can improve the missiles faced hot environment.

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 it
