HABITAT FIRE RISK & PREDICTIVE MISSION LAB
Aerospace Fire Safety & Combustion Workbench
Rank NASA microgravity combustion experiments for a crew habitat, predict flammability and extinction from real flight data, and study smoke detector response.
Cross-investigation connections
Cross-investigation connections (per PSI records)
DAFT qualified the SAME smoke counter
DAFT / DAFT-2 was run to mitigate risk for SAME: a TSI P-Trak modified for microgravity (capillary alcohol recycling) was compared with a DustTrak using Arizona Red Dust as the aerosol standard. SAME / SAME-R then relied on that P-Trak to count smoke aerosols.
BRE: gaseous fuels standing in for solids in still air
ACME BRE burns CH4/N2 and C2H4/N2 on 25 and 50 mm porous burners to establish burning conditions in a quiescent microgravity ambient in terms of condensed-fuel material properties; the record lists the 14.7 psia / 21 %, 10.2 psia / 26.5 % and 8.2 psia / 34 % O2 habitat atmospheres as planned test atmospheres.
CFI-G: inside-out (inverse) spherical flames, high O2
Normal and inverse spherical diffusion flames of propane, butane and ethane blends. The CFI-G table lists XO2 from 0.12 to 0.85 (O2 mole fraction XO2, mol/mol, dimensionless: standard combustion-symbol convention, user-confirmed and not stated in the PSI file; 0.85 matches the 85 % O2 in the investigation text).
E-FIELD: electric field isolated from buoyancy
Up to 10 kV between burner and mesh; ion current and flame response are measured. Whether the ionic body force can emulate partial gravity is a research hypothesis, not a result in the ingested PSI files. No lunar-gravity (LUCI / FM2) data are present in the ingested files.
0 g and 1 g bound intermediate gravity (concept only)
BASS-II tests whether materials burn as well in microgravity with adequate ventilation as in normal gravity, bridging NASA-STD-6001 Test #1 (1 g) and microgravity. The PSI tables hold 0 g rows only (inferred from flight metadata); there are no 0.16 g, 0.38 g or 1 g rows.
