Advanced Geared Turbofan 30,000lbf – Electrified (AGTF30-e) Dynamic Engine Model and Controller(LEW-20614-1)

The Advanced Geared Turbofan 30,000lbf - Electrified (AGTF30-e) is a dynamic model of a geared turbofan with electrification options. The model is built upon the previously released Advanced Geared Turbofan 30,000lbf (AGTF30). The model was constructed with the Toolbox for Modeling and Analysis of Thermodynamic Systems (T-MATS) within the MATLAB/Simulink Coding environment. The engine model is based upon the same NASA N+3 concept as the original AGTF30. It features a compact core and a variable area fan nozzle. The AGTF30-e has several features that can be leveraged to carryout numerous studies with respect to electrification. The model can represent a conventional engine or a mild hybrid that includes some electrified features. The model can also represent boost operation, which defines thrust augmentation over key mission segments. The final primary operating mode is power extraction, in which a significant amount of power is extracted from the engine shafts to produce thrust elsewhere on the airframe. In addition, there are options to enable additional features such as electric power transfer (EPT) to enhance performance at low engine power levels, and Turbine Electrified Energy Management (TEEM) to improve transient operability and alleviate dynamically driven design constraints. Finally, the model can implement two methods of engine and electric machine integration. One method provides a baseline through integrating electric machines with each engine shaft. The other method reflects the Versatile Electrically Augmented Turbine Engine (VEATE) gearbox approach and couples the two engine shafts though a planetary gearbox that can be used to manipulate power transfer through the electromechanical powertrain.
