12 of 41 extracted findings · verified first, then by AI confidence

  1. 01

    In microgravity, increased particle sizes are observed in some cases, and the relative performance of ISS and space-shuttle smoke detectors changes.

    Other · NTRS 20070031686 · p. 1 · AI confidence 95% · Unverified

  2. 02

    Well-ventilated flames and established fires emit smaller particulates that are readily detected by ionization detectors.

    Detection · NTRS 20070031686 · p. 7 · AI confidence 95% · Unverified

  3. 03

    Current spacecraft smoke detectors were designed based on normal-gravity conditions due to a lack of microgravity smoke data.

    Other · NTRS 20070031686 · p. 1 · AI confidence 95% · Unverified

  4. 04

    Smoke detector design must be based on low-gravity data because liquid smoke aerosols require on-orbit measurement of smoke particulate size distribution.

    Prevention · NTRS 20070031686 · p. 18 · AI confidence 95% · Unverified

  5. 05

    The modified P-Trak demonstrated functionality in low-gravity during the DAFT experiment.

    Detection · NTRS 20070031686 · AI confidence 95% · Unverified

  6. 06

    The ISS cabin environment has particulate levels substantially below those of the space shuttle and typical ground-based environments.

    Other · NTRS 20070031686 · p. 1 · AI confidence 95% · Unverified

  7. 07

    Improvements in LED and diode laser technology have reduced the cost and increased the stability of photoelectric fire detectors.

    Detection · NTRS 20070031686 · p. 7 · AI confidence 95% · Unverified

  8. 08

    Smoldering fires and overheated (pyrolyzing) materials produce larger particulates that favor scattering detectors.

    Detection · NTRS 20070031686 · p. 7 · AI confidence 95% · Unverified

  9. 09

    Current fire detection systems in space were developed without spacecraft fire data.

    Detection · NTRS 20170007283 · p. 7 · AI confidence 95% · Unverified

  10. 10

    Teflon smoke generated in GASP experiments would never trigger the ISS smoke detector alarm.

    Detection · NTRS 20170007283 · p. 30 · AI confidence 95% · Unverified

  11. 11

    Detection times for GASP experiments ranged from 1 minute to 6 minutes, which was considered too slow.

    Detection · NTRS 20170007283 · p. 30 · AI confidence 95% · Unverified

  12. 12

    The most likely source of a fire in spacecraft is overheating electronic equipment.

    Prevention · NTRS 20170007283 · p. 9 · AI confidence 95% · Unverified
