Abstract:
This paper reports on a series of experiments that were conducted on a partial-g parabolic flight campaign to determine key parameters of hoppers, designed for regolith sampling, science experiments, or in situ resource utilization (ISRU) processes on Moon or Mars. A major problem related to these applications is the clogging of feeding and conveying devices due to the physical properties of the regolith. In the experiments the flow rate of two representative lunar regolith simulants (JSC-1A and...     »
