An Adaptive-Configuration Control System for Aircraft Thermal and Energy Management System

ABSTRACT: Hybrid technologies and adaptive resource management can significantly enhance the capability and range of next-generation aircraft. To implement this strategy, we propose to develop a control system to configure the Adaptive Power and Thermal Management System (APTMS) based on the subsequent flight profile to enable the APTMS to use the most appropriate cooling system(s), heat sink(s), and energy source(s) to maximize the aircraft capability while minimizing fuel consumption. Based on the planned flight profile, the control system employs reduced-order physical models to forecast the performance of the APTMS with a given configuration. Based on the predicted performance, the system will then optimize the configurations for the remaining flight periods to maximize performance objectives. In Phase I, we devised an advanced optimization algorithm, developed a simplified model for the APTMS, implemented an integrated APTMS configuration optimization software package, and demonstrated its ability to identify optimal configurations of the APTMS during a flight to reduce the APTMS operation fuel penalty. In Phase II we will build and validate the APTMS optimization software with detailed physical models, use the software to identify the optimal thermal architecture for the APTMS and deliver the optimization software to the Air Force for further evaluation and development. BENEFIT: The proposed control system will enable future aircraft to fully realize the performance benefits of adaptive energy and thermal management, and enhance the capability and range of aircraft. In the near term, the control system will support the demonstration of the Integrated Vehicle Energy Technology (INVENT) program at the Air Force. In the long term, the control system will significantly enhance the static and dynamic performance of aircraft thermal management systems while reducing the overall vehicle fuel consumption. Commercial applications include more electric aircraft, air-conditioning systems, and thermal management systems for electronics and computer systems.
