More Electrical Aircraft (MEA) are becoming increasingly popular, as they offer a number of advantages over traditional aircraft, such as reduced weight, improved fuel efficiency, and lower emissions. Hybrid electric aircraft (HEA) are a type of MEA that use both electric and conventional engines to generate power. This allows for a more flexible and efficient use of energy, and can lead to significant reductions in fuel consumption and emissions. One of the key challenges in designing HEA is the optimization of the power chain. The power chain includes all of the components that are involved in converting engine power into electrical power, and then converting that electrical power back into mechanical propulsion power. The optimization of the power chain is critical in terms of reducing weight and improving reliability. This project aims to focus on the power chain of MEA, including the shaft-rectifier-generator-inverter-motor system. The project will explore both component level and system level solutions to optimize the power chain for weight and reliability. Development of new materials and designs for generators, inverters, and motors that are lighter and more efficient. Development of new control algorithms for power electronics components that improve efficiency and reliability. Development of new system architectures for power chains that are more efficient and reliable. Integration of the power chain with other aircraft systems, such as the flight control system and the energy management system. Development of new tools and methodologies for the design and optimization of power chains. The project is expected to make significant contributions to the field of MEA design, and to help accelerate the commercialization of MEA technology.
