In this joint AIAA / SAE course, participants will learn about Electro-chemical Energy Systems (EES), with an emphasis on electrified aircraft propulsion and power applications. The course will present the fundamentals in chemistry, materials science, electrical, and mechanical engineering for various EESs including high voltage battery systems (Li-ion and beyond) and fuel cells (PEM, solid oxide fuel cells, and others). The challenges of each EES option will be examined as it applies to aircraft electrification, including:
- Specific energy, efficiency, electrical, thermal, mechanical integration, operating conditions, and other technical considerations
- Inherent hazards, risk severity, and available mitigation strategies
- Ground handling, operations / maintenance, and recharging / refueling
- Economics, life cycle considerations, infrastructure requirements, and certification challenges
- The intended application: Electrified propulsion and power (high level) and what is needed to make a successful EES for aircraft
- The technology: Discuss the inner workings and the ‘balance of plant’ associated with battery and fuel cell systems
- The challenges: Look at the limitations, failure modes, and inherent risks for batteries / fuel cells and supporting subsystems in the context of flight / ground operations
- The outlook and outcomes: Consider the technological advancements that will be needed for the future, the quantitative environmental and economic impacts on aviation, the conceptual change to aircraft operations for end-users, and current government, industry, and regulatory activities
