OBJECTIVES

Repeat SAME with improved diagnostics, compare flight and ground smoke measurements, and evaluate the ISS and Shuttle smoke detectors against known particle size distributions.

Sensors & measurements
  • Aerosol instruments measuring particle number, diameter and mass moments
  • Thermal precipitator with transmission electron microscopy
  • Commercial smoke detector
  • ISS and Space Shuttle smoke detectors
Variables tested
  • Smoke material type
  • Aged versus un-aged smoke
  • Particle size distribution moments
  • Flight detector response
Key findings
  1. 01Flight and ground measurements were compared for Teflon, Kapton, cotton, silicone rubber and Pyrell smoke.
  2. 02Moment measurements gave particle number, diameter and mass concentrations; geometric statistics followed under a lognormal assumption.
  3. 03Transmission electron microscopy and ground SMPS data validated the particle statistics.
  4. 04The reflight strengthened the low-gravity smoke baseline used to design more reliable spacecraft detectors.
