Presenter: Sara Roggia
Abstract: Aerospace electrification spans a diverse range of platforms, each imposing distinct requirements on power system architecture. A propulsion system optimized for a fixed-wing commuter aircraft will differ fundamentally from one designed for a helicopter or a lightweight training aircraft, not only in power and speed ratings, but in how safety, redundance, and integration challenges shape every design decision. This webinar examines how magniX approaches system-level design across three distinct platforms. The magni650 Electric Propulsion Unit, a ~700 kW direct-drive system powering aircraft such as the Eviation Alice, is designed around FAA Part 33 special conditions and represents the most rigorous certification pathway for electric propulsion to date. The HeliStorm engine family, targeting rotorcraft applications at ~330 kW with operating speeds of 6,000–7,000 RPM, addresses the unique demands of vertical lift including weight sensitivity, high-speed operation, and scalability from light single-engine to hybrid-electric twin-engine configurations. Possible applications for training aircraft demonstrate how the design must balance energy density, cycle life, and safety features to meet the specific mission profile of a high-utilization training platform. Through these three case studies, the presentation illustrates how application-specific requirements including airworthiness standards, redundancy architectures, thermal management strategies, and integration constraints drive fundamentally different optimization paths, even within a single company’s technology portfolio.
Sara Roggia (IEEE SM’20, M’16) received her Bachelor’s and Master of Science degrees in Electrical Engineering from the Politecnico di Bari, Italy, and her PhD in electrical machines design from the University of Nottingham, UK, as a Marie Curie Fellow in 2017. Her doctoral research focused on the development of novel electrical machine technologies for aircraft ground operations within the more electric aircraft initiative. In May 2017, Sara joined Motor Design Limited (MDL), where she worked on the design of various electrical machine topologies. In September 2018, she joined SAFRAN in France as a Senior Research Engineer. Since December 2020, she has been with magniX in Everett, WA, USA. Sara initially joined as a Senior Electric Propulsion System Engineer, was appointed Technical Fellow in 2021, and became Head of Protection and Controls in 2022. In 2024, she was appointed Head of the magniDrive Project, and in November 2026, she was named Deputy Chief Engineer, a role she holds alongside her continued responsibilities on the magniDrive program. Sara’s primary areas of expertise include algorithm definition and implementation for electric propulsion systems, as well as hardware inverter design for electric propulsion units. She holds seven patents focused on motor design and control and has authored more than 18 scientific publications. In May 2024, she was awarded the 10th Nagamori Award from the Nagamori Foundation in recognition of her research contributions to electrical machines and drives for aerospace applications.
