Development of Advanced Gas Turbine Engines with improved performance and durability requires a detailed knowledge of the heat load on engine components. Due to increased pressure ratios, higher temperatures and alternative fuels, design systems require determination of radiative as well as total heat loads on hot section components. Porous plug radiometers are instruments designed to measure the radiative load on hot engine components, exclusive of convective effects. These instruments depend on blowing through a porous surface to uncouple the convective heat load. An energy balance approach is then used to determine the radiation load on the surface.
