Study of Impact Frequency Effects on Hypervelocity Erosion Processes

Abstract

Erosive particle impact frequency-dependent mechanisms are examined to determine potentially important spatial and time-dependent interactions which can influence flight and ground test erosion performance. Specific consideration is given to the interaction of incident erosive particles with impact-generated ejecta and to the shielding effect which this interaction can have on the observed material erosion characteristics. It is concluded that debris shielding does not occur to any significant degree in the real flight environment, but could be a potential problem in correlating high concentration range/track test results.
