Journal ArticleDOI
Experimental investigation of ablation and pyrolysis processes of carbon-phenolic ablators in atmospheric entry plasmas
TL;DR: In this article, the authors investigate the resistance of carbon-phenolic ablators to high heating conditions and characterize gas-surface interaction phenomena, including the interaction of the pyrolysis gases with the hot plasma flow.
Journal ArticleDOI
Surface temperature jump beyond active oxidation of carbon/silicon carbide composites in extreme aerothermal conditions
TL;DR: The behavior of carbon/silicon carbide composites at very high temperatures is investigated in an inductively-coupled plasma generator that simulates atmospheric re-entry aerothermal conditions for space vehicles as discussed by the authors.
Journal ArticleDOI
Microstructure and gas-surface interaction studies of a low-density carbon-bonded carbon fiber composite in atmospheric entry plasmas
TL;DR: In this article, carbon-bonded carbon fiber (CBCF) composites are used for the production of low-density carbonphenolic thermal protection systems (TPS), which requires new experimental data for model development and validation.
Journal Article
Microstructure and gas-surface interaction studies of a low-density carbon-bonded carbon fiber composite in atmospheric entry plasmas Part A Applied science and manufacturing
TL;DR: In this paper, carbon-bonded carbon fiber (CBCF) composites are used for the production of low-density carbonphenolic thermal protection systems (TPS) for spacecraft.
