Heat Flux Characterization of Fuel Lean and Fuel Rich Environments
Oxyacetylene torch testing has proven to be an effective method to screen the utility of ablatives and ablative polymer nanocomposites for use in defense and aerospace applications. In our study, the ablation performance of silica- and carbon-fiber polymeric composites in fuel lean and fuel rich environments will be compared. The high definition (HD) and infrared (IR) video cameras will be used to visually analyze the ablation performance. A two-color IR pyrometer will be used to determine the surface temperature of the samples throughout the experiments. The backside heat soak temperature, mass loss, and ablation rate of each sample will be measured in order to thoroughly understand their ablation performance and insulation property. From this data, the effectiveness of using a fuel rich environment in ablation testing will be determined.
