Abstract
Three-impulse-at-one-spot impulse thruster contains three paralleling igniters,which are ignited by external logic circuit and it combusts in the mutual combustion chamber.High temperature and high pressure gas is produced and the gas spouts out through Laval nozzle so that the ballistic trajectory of missiles or rockets' bodies can be corrected many times.The output performance of thrust is the most important parameter to measure the effects of ballistic trajectory correction and it is showed by impulse thrust,pressure in combustion chamber and total impulse.Factors that affect the output performance of thruster were analyzed and studied from three aspects which are the main charging pressure,sealing film force surface diameter and the throat diameter of Laval nozzle.It was proved through a series of experiments that with the increase of main charging pressure,output performance of thruster improved first and then decreased,therefore 21.3 MPa was chosen.A smaller sealing film force surface diameter could prevent sympathetic ignition effectively,but too small diameter could cause an extra energy loss.Therefore,diameter of 3 mm was suggested.When the throat diameter of Laval nozzle rose up,the output performance of thruster was enhanced,but at the same time all structural mass increased,which conflicted with the miniaturization of ballistic trajectory correcting devices.In addition,the trend of output performance change of thruster with the change of main charging amount was most obvious and stable when the throat diameter set to 4 mm.Hence,4 mm throat diameter of Laval nozzle was proposed.

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
