Microstructure and gas-surface interaction studies of a low-density carbon-bonded carbon fiber composite in atmospheric entry plasmas Vrije Universiteit Brussel
Experimental investigation of the material response of carbon composite ablators in the VKI Plasmatron facility Vrije Universiteit Brussel
Two di fferent test gases were used, air and nitrogen, for heat flux levels ranging from 0.85MW/m^2 to 4.5MW/m^2.
A comprehensive experimental setup was developed with ...
Material response characterization of a low-density carbon composite ablator in high-enthalpy plasma flows Vrije Universiteit Brussel
materials for the thermal protection system in order to shield the spacecraft from the severe heating during
reentry. In this paper, we present the results of an elaborate test campaign on a lightweight carbon composite
ablator with the aim of defining a procedure for material response characterization in a 1.2-MW ...

A high heating rate pyrolysis model for the Phenolic Impregnated Carbon Ablator (PICA) based on mass spectroscopy experiments Vrije Universiteit Brussel
A novel model for the pyrolysis of the Phenolic Impregnated Carbon Ablator (PICA) at high heating rate is developed and calibrated based on high fidelity thermal decomposition experiments. The calibration relies on accurate quantification of pyrolysis gases obtained from mass spectroscopy analysis during thermal decomposition at fast heating rates simulating flight conditions. Model calibration is achieved by coupling the Porous material ...

Competitive kinetic model for the pyrolysis of the Phenolic Impregnated Carbon Ablator Vrije Universiteit Brussel
Carbon/phenolic ablators are successfully used as thermal protection material for spacecraft. Nevertheless, their complex thermal degradation is not yet fully understood, and current pyrolysis models do not reproduce important features of available experimental results. Accurate and robust thermal degradation models are required to optimize design margin policy. We investigate whether the competitive kinetic schemes commonly used to model ...
Transport properties of carbon-phenolic gas mixtures Vrije Universiteit Brussel
The development of a new generation of ablative thermal protection systems based on carbon-phenolic composite materials demands the accurate determination of transport properties of pyrolysis gases mixed in various atmospheres. The present work provides recommended collision data for the calculation of the transport properties for Mars and Earth re-entries. A review of available potential data is given for species in the atmospheres of Earth ...
