Bringing the chamber up
Choose a cabin atmosphere and list the materials you're considering. FireLine ranks them against NASA's real microgravity combustion tests and shows the evidence behind every call.
Defaults to the live FireLine worker. Override with ?api= or ?mock=1 in the address bar.
See where this atmosphere would be used. The 3D view runs in OpenSpace, a free desktop app; FireLine steers its camera to match the mission you pick. OpenSpace only shows the location. It plays no part in the verdicts.
For each material and pressure, the worker returns the nearest O₂-and-pressure bucket that NASA actually tested, with the count of tests whose recorded outcome was extinction or disruption. The remainder is the burn share.
Pass means a burn share of one third or less. Caution means up to two thirds. Fail means more. A Pass is downgraded to Caution when the scenario sits outside the range tested for that material, or when its oxygen level is higher than any test of it.
Confidence, out of 99, grows with the number of tests in the bucket and with how close that bucket is to the scenario: an exact bucket scores higher than interpolation, which scores higher than extrapolation.
This is FireLine's reading of historical test outcomes, not a NASA flammability certification. The dataset covers fuel materials only; fire suppressants are not in it.
Have a new NASA combustion CSV? Upload it and FireLine matches its columns the same way the PSI scrape was matched, adds it to Tiger Data, and folds it straight into the ranking and envelope above — the dataset grows as new experiments come in, instead of staying fixed. Uploads are marked community-contributed, unverified everywhere they're shown or cited, until someone reviews them; they never get presented with the same authority as the NASA PSI data.
