Abstract Details

2018, Master of Science, Ohio State University, Electrical and Computer Engineering.
The aviation industry has been one of the biggest beneficiaries of the major rise in electric power system technology for the past several decades. With more electric aircraft (MEA) now defining the new industry standard, the new future vision is toward all-electric aircraft, wherein conventional power systems and propulsion sources are electrified. Achieving all-electric aircraft will require optimization of energy source usage onboard existing MEA. By first considering the problem under a simplified environment, such as a hybrid unmanned aerial vehicle (UAV) power system, energy optimization techniques can be explored before being considered for larger applications. This work first presents a method for system modeling and optimizing the usage of energy sources for a hybrid UAV system. The energy optimization is presented through a dynamic programming algorithm, which considers the system under only the fundamental constraints. The system modeling aspect is presented as a virtual UAV model, which considers all of the nonlinear constraints present upon the system. The virtual UAV model validates the results from the algorithm to ensure the anticipated operation is feasible under realistic system constraints. This work then uses the results from the hybrid UAV study, and extends it to a study of larger commercial aircraft with the focus being on the transition to all-electric aircraft. Power system architectures, voltage levels, power requirements, and load characteristics are examined on existing electric vehicle applications, and predictions are made of what the future all-electric aircraft will look like. Additionally, the primary challenges of accomplishing “all-electric” status are discussed, including existing propulsion methods and battery chemistry. Finally, the paper discusses some recent advances toward all-electric aircraft, which further shows the bright future for the all-electric aircraft.
