Measurements of air plasma/ablator interactions in a 50 kW inductively coupled plasma torch

Studies of the UV and visible emission from an atmospheric pressure air plasma in local thermodynamic equilibrium and its interaction with two carbon-based ablative materials were performed in an inductively coupled plasma torch. These experiments were conducted at a plate power of 40 kW, which produced an air plasma of near 6500 K. Recession rates and product species profiles were measured for two different materials (ASTERM and carbon bonded carbon fiber) at two different flow conditions
