Single values are documented test conditions, not flammability limits. Ranges appear under variables tested.

OBJECTIVES

Investigate large-scale flame growth and material flammability limits in space using a cargo vehicle after it departs the station, avoiding risk to the crewed ISS.

Sensors & measurements
  • Video and still imaging
  • Thermocouples
  • Pressure and oxygen sensors
  • Flow duct instrumentation
Variables tested
  • Large-scale flame growth over a meter-class fabric sample
  • Material flammability limits at practical spacecraft scale
  • Flow-duct conditions during flame spread
Key findings
  1. 01Conducted the largest fire experiment in space to date; previous tests were roughly the size of an index card.
  2. 02Ignited a 0.4 m by 1 m SIBAL sample inside a dedicated flow duct while the vehicle flew free.
  3. 03Provided practical-scale data on flame growth that small glovebox samples could not reproduce.
