During the past five years, a specific class of carbonaceous materials consisting of carbon matrices reinforced with high strength carbon fibers has been developed for application on high-performance missiles as nosetip, heatshield, leading edge, and rocket nozzle materials. This paper deals with the effects of instrumentation installation design parameters upon the ablative performance of the nosetips as observed in recent ground tests. Included in these parameters were the nature of the radioactive source i.e., wire or pellet, the diameter of the hole drilled into the nosetip into which the pellet andor wire source assembly is inserted, the method of bonding the source assembly into the nosetip, the configuration of multiple source assemblies mounted into the nosetip, and the orientation of installing these source assemblies radially or axially into the nosetip. The results of these tests, as discussed in this paper, showed that certain installation design parameters had a major impact upon the ablation performance of the carbon-carbon nosetips.
