Abstract

fetched live from OpenAlex

This paper presents the internal ballistic design, fabrication procedure, and performance evaluation of a Micro Electro Mechanical Systems (MEMS) solid propellant thruster array chip. The internal ballistic design was carried out to predict the performance of the thruster. Only the photosensitive glass wafer was used as the bare material for the thruster. We developed the micro igniter with improved structural stability by using a glass membrane with a thickness of tens of microns. The solid propellant was loaded into the propellant chamber without resort to a special technique due to the high structural stability of the glass membrane. An MEMS Solid Propellant Thruster (MSPT) array was fabricated through anisotropic etching of photosensitive glass. Ignition and combustion tests of the fully assembly MEMS thruster were performed successfully. Nomenclature P = pressure t = time R = gas constant T =

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.
