LIVE DATA

PROPULSION LAB — an open educational rocket-propulsion tool. Ideal-rocket model: CEA-derived combustion properties (interpolated) · isentropic frozen nozzle w/ efficiency factors · lumped feed-system lag per cycle · Saint-Robert burn law r = aPcⁿ with quasi-steady grain burnback. Preset outputs are pinned to published figures within ±5–10% (see VALIDATION readout on presets); two-phase flow, erosive burning, film cooling and real turbomachinery maps are not modelled. Certify nothing with it.
