The efficiency of turbine engine powerplants based on traditional design practices is susceptible to the transient operation of the engine. These engines are designed to operate on the efficient operating line across their operating maps. Transient effects (e.g., throttling) may cause the engine to deviate from the operating line and thus decrease the overall efficiency of the machine. Hybrid electric turbine engines will typically use electric machines on the low and high spools of the engine to allow for extracting and inserting power into the machine. Turbine Electrified Energy Management (TEEM) concept takes advantage of these electric motors to control the deviation from the operating point of the engine. We have investigated the potential benefits of this advanced control concept in designing the engine components. It can be inferred that the engine components (specifically the compressor) can benefit from the addition of electric motors. And the traditional design practices may be revolutionized as a result. This work presents the potential benefits of the operability influenced design on a turbofan engine. A traditionally designed engine is considered in this work and the high pressure compressor was redesigned using the benefits of TEEM concept to allow for an overall more efficient engine design. Current computational tools were improved to allow for an entropy rise analysis of the engine components. Based on entropy rise models the improvements in the compressor design were implemented and investigated. This analysis can be extended to the low pressure compressor as well as the high pressure and low pressure turbines to further improve the efficiency of the considered design.
