Abstract Details

2020, Master of Science, Ohio State University, Mechanical Engineering.
Volatile oil prices, rapidly increasing air travel demand, growing concern for health and climate impacts of emissions, and limited performance of existing aircraft technologies have generated substantial interest in distributed propulsion and hybridization, even without significant government regulation. This work details the development of the Map-based Aircraft Propulsion Simulator (tMAPS), a modular framework of reduced-order models of aircraft propulsion subsystems, and its application in optimizing the size and control of a battery energy storage system (BESS) in a hybrid-electric, distributed-propulsion (HEDP) regional jet aircraft. tMAPS is validated against the NPSS-based Georgia Tech Hybrid Electric Aircraft Test-bed. The supervisory energy management strategy is formulated into a discrete-time optimal control problem and solved via dynamic programming. Both state-of-the-art and future battery technologies are evaluated, with energy density ranging from 230-400 Wh/kg and power density ranging from 350-1200 W/kg. The optimal energy management strategy is evaluated as a function of BESS size, cell chemistry, and mission range to deduce system-level implications. The performance of HEDP is compared to a turbo-electric, distributed-propulsion (TEDP) aircraft that assumes improvements in weight, drag, and engine efficiency consistent with a regional jet entering operation in 2035.
