The Energy Efficient Engine (EEE) program was funded by NASA in the mid-1970s to develop a more efficient turbofan engine for aircraft. The contractor reports and geometry of the EEE engines developed by GE and Pratt & Whitney are no longer proprietary and this is now public information. Under the NASA Transformational Tools and Technologies (TTT) project, NASA is using the EEE combustor and high-pressure turbine as a representative combustor/turbine combination to support development of fully-coupled combustor-turbine simulations using computational fluid dynamics (CFD). Geometry, CFD grid and CFD boundary condition files have been created based on publicly available information extracted from NASA contractor reports, such as NASA-CR-167980 (1982), NASA-CR-167955 (1982), NASA-CR-168274 (1984), NASA-CR-168289 (1984) and NASA-CR-168301 (1984). NASA is providing these geometry, grid and boundary condition files to other researchers to promote development of tools for the coupled analysis of aircraft combustors and high-pressure turbines.
