Abstract:

This paper deals with the continuing study of the effects of instrumentation installation design parameters upon the ablative performance of carbon-carbon nosetips as observed in ground tests conducted during the past 18 months at the Air Force Flight Dynamic Laboratory AFFDL 50 MW Arc Jet Test Facility. Some of the parameters studied in Phase II were the differences in the structure of the various carbon-carbons the clearance between an instrumentation rod and the hole in which it is installed carbonization of the bonding material charring out of the bonding agent and, further study of multiple source assemblies mounted into the nosetip. In general, the Phase II results have shown that even the subtlest, and assumed harmless, change in an instrumentation installation parameter produced very large and sometimes unexpected and undesired effects on carbon-carbon nosetip ablation performance.
