Thermal Evaluation of Selected Ablative Materials in Transient Low Heat Flux Environments.
Abstract
This thesis attempts to evaluate the thermal performance of ablative materials subjected to a common, transient, low-heat flux environment. Experiments were conducted to provide backface, substrate, and surface temperature histories for each of the ten ablators under examination. The tests are useful in determining the relative merit of the materials, and can be used as a screening tool by removing obviously poor performers from further evaluation. Data obtained during testing are correlated with results of a sophisticated computer ablation model. The ultimate objective of these experimental evaluations is the relative ranking of materials studied, and subsequent selection of the ablator which provided the best thermal protection in the environment of concern, based upon applicable thermal insulation performance indices.
