			MULTISTAGE CYCLONE PARTICLE SEPARATOR INITIATED The Tribology and Mechanical Components Branch has achieved initial operation of a multistage cyclone particle separator for the Dust Management Project (DMP). The separator will be used to produce specific size fractionated samples of lunar regolith simulants. A cyclone separator is necessary because lunar dust, which is in the nanometer to 20-micron size, is too fine to be sieved. The samples are being used for testing and verification of dust mitigation technologies and Constellation flight systems, as well as toxicological studies of the effects of dust exposure to humans. The DMP has conducted performance verification, size fraction characterization, and provided size separated simulants for use in testing an active particle remover (AC electric grid) for dust mitigation.   Above: Multistage Cyclone Particle Separator     View Highlights Archive...
