Sandia High Pressure Ablation Test in the AEDC 5-Megawatt Arc Heater Test Unit, Series II.

摘要

Three ablation test runs, involving 15 test models, were made in an arc-heated free-jet facility using air as the test fluid. Test runs were conducted to screen and examine the ablation performance of various materials with different microscopic structure. The investigation was accomplished at Mach number 2.3 with measured reservoir pressures ranging from 98 to 100 atm and enthalpies from 2310 to 2530 Btu/lb. Test models were hemisphere-cylinder specimens of composite materials. Most of the models were instrumented with a thermocouple embedded inside the specimen.
