Aerothermodynamic bases for the development and design of high-performance heat shield systems
Abstract
The burning of graphite in a stationary, hot oxygen-nitrogen flow, relevant to the development of materials for high-performance heat shield systems for reentry vehicles, is experimentally studied. A steady heat exchange with a suitably positioned radiation shield is observed. Carbon dioxide formation occurs predominantly at the upper surface of the graphite. Realistic burning rates are obtained only when the constitutive relations for polynary transport processes are taken into account. Differences in graphite type can cause up to 20 percent variation in the mechanical erosion processes at the plate surface.
