Testing a transpiration cooled Zirconium-Di-Boride sample in the plasma tunnel at IRS

Abstract:

Transpiration cooling is an active thermal protection system (TPS), in which a coolant gas is fed through a porous material. This requires a material that stays structurally stable at high temperatures, while having the desired permeability. This paper explores transpiration cooling of Ultra-High-Temperature-Ceramics (UHTCs). A stagnation probe with transpiration cooled ZrB2 was tested in a plasma wind tunnel at a null point heat ux of 3.59 MW/m2 in steady state and transiently at 2 MW/m2. T...
