Abstract: An experimental and numerical investigation of phantom cooling effects on cooled and uncooled rotating high pressure turbine blades in a full scale 1 + 1/2 stage turbine test is presented. Objectives set to capture, separate, ...

Abstract: This article presents results from the original development of a long wavelength infrared (LWIR) high-pressure turbine (HPT) blade thermal imaging system on a Full-Scale Cooled 1 + 1/2 Stage Rotating Turbine in the Air ...

Abstract: The focus of the study presented here was to investigate the interaction between the blade and downstream vane of a stageandonehalf transonic turbine via computation fluid dynamic (CFD) analysis and experimental data. A ...

Abstract: Facilities such as the Turbine Research Facility (TRF) at the Air Force Research Laboratory have been acquiring uncooled heat transfer measurements on full-scale metallic airfoils for several years. The addition of cooling ...

Abstract: Accurate predictions of unsteady forcing on turbine blades are essential for the avoidance of high-cycle-fatigue issues during turbine engine development. Further, if one can demonstrate that predictions of unsteady ...

Abstract: Thin-film heat flux gauges (HFGs) have been used for decades to measure surface temperatures and heat flux in test turbines with the majority being used in facilities that are short-duration. These gauges are typically ...
