All-electric aviation is increasingly at the forefront of research and development with the promise of zero-carbon air travel and a 40% reduction in operating costs for short-haul flights. According to the Advanced Research Projects Agency-Energy (ARPA-E), a propulsion system efficiency greater than 93% and specific power greater than 12 kW/kg is required for an electric narrow-body commercial airliner to complete a typical 5-hour flight, which represents a 3x step change over the specific power of commercially available solutions. This presentation will discuss the technology development required to achieve this step change, starting with presenting an alternative framework for the scaling of machine specific power that addresses ubiquitous misconceptions about specific torque and winding current density, continuing to identify areas of performance bottlenecks, and culminating with the materials and manufacturing technologies required to overcome these barriers to performance. Ultimately, an overview will be presented for the design of a synergistically cooled integrated motor drive composed of a highly saturated, high frequency machine with additively manufactured coils and a silicon carbide inverter. Highlights of analysis using JMAG Designer will be included to provide illustrative examples.
