Aeronautical power chain (aircraft power systems)

The presentation will begin with an introduction retracing the evolution towards increased electrification in aircraft, from the concept of the “more electric aircraft” to future prospects for all-electric airplanes. We will review the development of on-board power needs, highlighting iconic examples such as the Concorde and next-generation aircraft like the A350 and B787. An overview of the future of electric protection devices up to 2050 will be presented, along with a discussion of the challenges linked to increasing power and the introduction of high-voltage systems, including HVDC, HVAC, and PWM. The main elements of the power chain will also be briefly introduced.

The section dedicated to generation will highlight power system architecture, the diversity of generation sources, and an introduction to power electronics, with a focus on the associated electromagnetic compatibility (EMC) challenges. The harness segment will explore issues related to high-voltage power transport, crosstalk, shielding, and will include a focus on harness simulation. The engine section will present the transition towards “Smart Engines,” with an introduction to their specific challenges, particularly regarding filtering.

Finally, the presentation will conclude with a recap of the solutions proposed to meet the challenges identified in generation, harness, and engine systems, followed by a brief bibliography.
