Research on the Influence of Cavities in Charge on the Formation and Penetration Performance of Jets
Bibliographic record
Abstract
Abstract To investigate the effect of charge cavities on the formation and penetration of shaped charge warheads, we numerically simulate and calculate shaped charge warheads with different cavities using the finite element method. Combining theoretical analysis and numerical simulations, charge structure splitting was performed to obtain jet morphology and properties data for different cavity locations in both axial and radial dimensions. The mechanism of the effect of cavity position on detonation wave propagation, liner propellant, and jet formation processes in shaped charges is analyzed. It has been shown that charge cavities can change the propagation waveform of detonation waves. The effect of different cavity positions on the jet formation and penetration properties varies; Based on the detonation drive theory, a geometrical model was developed to investigate the effect of the charge cavity position on the jet velocity; The shaped charge warhead structure designed using this model can change the propagation path of the detonation wave, adjust the driving process of the shaped charge cover, and effectively increase the head velocity and penetration capacity of the jet. By studying the influence of the cavity on the driving and jet forming processes of the shaped charge cover, the results indicate that a model established by reasonably adjusting the charge cavity to improve the jet damage performance can provide a certain basis for further optimizing the design of the shaped charge structure.

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.
