Feasibility of Standard Evaluation Procedures for Ablating Materials

Abstract

Twelve plasma arc heater facilities participated in a round-robin study to determine the feasibility of a standardized ablation test procedure. Teflon and high-density phenolic-nylon models having the same shape and size were supplied by Stanford Research Institute, and were evaluated at various enthalpies and heating rates under supersonic conditions. Calorimeters and pressure probes were also supplied by SRI, and interpretation of the results indicated that the best description of the test environment was given by the stagnation point heating rate and pressure. The mass loss rates for both materials as obtained from all facilities could be correlated in terms of these two parameters with a standard deviation of approximately ll%.
