This is the fourth in a series of reports describing the results of static test firings conducted to verify the performance of ablative nozzle components fabricated from low-cost materials andor low-cost manufacturing processes. The throat insert of this nozzle assembly exhibited extreme spallation. This was attributed to the lower-than-normal density and higher-than-normal residual volatile content of the cured component. A preliminary costperformance analysis, based on material cost only, confirmed the economy resulting from the use of asbestos composites. Transient temperature readings made by the use of bare-wire thermocouples indicated that the response to temperature fluctuations caused by the flow of percolating decomposition gases was more rapid than when using shielded thermocouples.
