Non-Uniform Temperature Distribution Generation of Resistively Heated Reinforced Carbon-Carbon

James Anthony Brennan

Abstract


Assessment of aircraft that operate within high Mach numbers have indicated that aerodynamic heating encountered within these conditions generates non-uniform temperature profiles along its external surfaces. Finite Element Modeling has been performed to assess the effect of resistive heating on Reinforced Carbon-Carbon with changing cross section has on surface temperature distribution. Changes in cross sectional area of Reinforced Carbon-Carbon generated non-uniform surface temperature distributions. Further investigation using ANSYS workbench has shown that non-uniform temperature profiles can be created and controlled by modifying the total Joule energy supplied and geometry configuration of Reinforced Carbon-Carbon model. Final non-uniform temperature distributions were influenced by the shape, power supplied and the heat loss mechanisms present in a resistively heated object. Conclusions and recommendations for future use of resistive heating methods were made.
