A rack was designed to study the dust ejections during a parabolic flight. Within an evacuated vacuum chamber (mbar, 1/1000 normal atmospheric pressure) a dust sample (JSC Mars 1A soil simulant) is placed and illuminated by a high power halogen lamp. The induced dust particle ejections are observed during all three g-phases (μg, 1g, 2g) and recorded.
An automatic data logging and recording system ensures the data collection. 3 operators are around the rack controlling the intensity of the light source, the pressure and the data collection as well as a device for reducing the cohesion between the individual dust particles.
The gravitational dependency of the ejections forces are reconstructed out of the collected data.
Besides scientific applications to Mars (dust devils and/or dust storms) and protoplanetary disks no direct industrial applications exist.
