Cabin Pressure Phase-Space Monitor

Interactive 2D phase-space simulator of a space station's cabin-pressure control loop: watch the (total pressure, O2 partial pressure) state trace live inside safe/hazard bands as a hull leak, crew load and controller gain drive the same effusion physics as the 3D version.

ControlsLeak hole diameter slider sets the hull breach's effusion area, a crew-size slider sets steady metabolic O2 draw, a controller-gain slider scales both makeup valves' maximum flow, a Simulate Puncture button snaps the leak open instantly, and a Reset button restores the station to nominal — the phase-space plot and strip chart update live as the state trace responds.

A space station cabin does not just need oxygen — it needs the right total pressure and the right O₂-to-N₂ ratio, because pure oxygen at sea-level pressure is a fire hazard (the Apollo 1 lesson) while low total pressure risks hypoxia. This 2D companion to the 3D particle-cloud simulator plots the cabin's state directly on a (total pressure, O₂ partial pressure) plane: safe and hazardous regions are drawn as bands, and the station's live state traces a path through them as a hull leak, crew metabolic load and an automatic dual-valve controller pull it around — the same ideal-gas, Dalton's-law and kinetic-theory effusion physics as the 3D version, read as a state-space trajectory instead of a particle cloud. A scrolling strip chart underneath plays the same two pressures out against time.

A 2D phase-space companion to the 3D cabin-atmosphere simulator: watch the station's live (total pressure, O2 partial pressure) state trace a path through safe and hazard bands as a hull leak, crew metabolic load and an automatic dual-valve controller pull it around, driven by the same ideal-gas, Dalton's-law and kinetic-theory effusion physics as the 3D version — plus a scrolling strip chart of both pressures over time.
