Title: Results From Tests on a High Work Transonic Turbine for an Energy Efficient Engine
Abstract: This paper will present the experimental results of the evaluation of two high work, transonic, single-stage turbines investigated under the Energy Efficient Engine Program. The objective of the E3 program, a joint P&WA/NASA program (NAS3-20646) is to provide an advanced technology base for a new generation of fuel-conservative turbofan engines. A single-stage turbine required fewer cooled airfoils, a reduced number of leakage paths and no interstage seals. These advanced energy efficient engines require high engine pressure ratios resulting in high expansion ratio, transonic, turbine designs which must have high aerodynamic efficiency. The goal of the turbine program is to develop a high pressure turbine that is compatible with the overall engine design and has an uncooled efficiency of 90.8 percent.
