“…This trend is confirmed by the technological choices of E-Fan X [10], in which megawatt-class motors and power electronics as well dc distribution in the kilovolt range are envisaged. Some research groups have investigated the use of permanent magnet machines for HEA and realized megawatt-class demonstrators [11], [12]. Note that the scientific debate on optimal machine topology remains open.…”

Aviation is a significant contributor to greenhouse gas (GHG) emissions in the transportation sector. As the adoption of electric cars increases and GHG emissions due to other modes of transport decrease, the impact of air travel on environmental pollution has become even more significant. To reduce pollution and maintenance, and ensure cheaper and more convenient flights, industry and academia have directed their efforts toward aircraft electrification. Considering various types of aircraft, several frameworks have been proposed: more-electric aircraft (MEA), hybrid electric aircraft (HEA), and all-electric aircraft (AEA). In the MEA framework, propulsion is generated by a conventional jet engine; however, all secondary systems (hydraulic, pneumatic, and actuation) are electrified. By further increasing electrification, electric motors can provide propulsion with the electric power supplied by the conventional engine (i.e., HEA) or from electrical energy storage (i.e., AEA). Power electronics and electrical machines play a key role in this scenario in which electric power must be efficiently generated, distributed, and consumed to satisfy extremely high requirements of aviation safety. This article provides an overview of recent advancements in aircraft electrification, and trends and future developments referenced to the global aviation roadmap.

“…From an architectural point of view, the electric propulsion features a high flexibility, thus enabling innovative technological solutions such as the concept of distributed propulsion for future aircraft [19] or the integrated power system for naval vessels [20]. Within this context, there is a critical need for reliable electric drive architectures with reduced mass and volume [10]. In fact, a typical concept of architecture is the hybrid turbo-electric layout [21], [22], whereas multiple prime movers drive electrical generators which feed independent DC power buses, thus offering several possibilities to effectively implement fault management strategies [2].…”

“…However, for both PMGs and SRMs, proper active AC/DC power electronic converters are required as controlled interfaces between the generator and the on-board grid. The presence of full-rated active power converters, which may feature a very complex structure especially in highvoltage and multi-phase scenarios [10], penalise significantly the overall weight and reliability [11], thus becoming the bottleneck of the system. In fact, such configuration involves several drawbacks, especially when high degrees of modularity and fault-tolerance are required:…”

Synchronous Homopolar Generators represent an attractive solution for the future of power generation in propulsive systems based on hybrid turbo-electric drivetrains. In fact they feature both a fully controllable excitation, similar to wound-field synchronous machines, and a very robust rotor like switched reluctance machines. The above features make this machine topology a promising alternative also to PM synchronous generators, even when DC power buses have to be supplied via diode rectifiers. The preliminary electromagnetic sizing of a 15 kW @ 15 krpm homopolar synchronous generator is proposed as a concept demonstrator, and then validated via 3-D Finite-Element analysis. The generation system is designed on purpose to supply two independent 600 V DC power buses for improved redundancy, by using 4 winding sections supplying 2 three-phase diode rectifiers connected in series per each bus to reduce the voltage ripple.
