   About Power Electronics Challenges in Aviation
By Marco BOHLLAENDER [View]
[Download]

Abstract: The aviation market is in change. The degree of aircraft propulsion electrification increases rapidlyand requires power semiconductor and power electronic solutions to fulfil different requirements thanin any other industry and application. The invited lecture will give a survey on those challenges anddepict their impact on the power electronic system design in electrified aircrafts.

   Aircraft Electrification - System-Level Potentials for Aviation Decarbonization
By Kathrin EBNER [View]
[Download]

Abstract: Aviation's ambitious climate targets have fueled the search for innovative and energy-efficient propulsion concepts. In that context, introducing electrical energy into the propulsion train opens up avast design space. Various architectures employing battery electric and/or fuel cell electric conceptshave been proposed and attract considerable attention fostered by their perspective contributions toaviation decarbonization. To understand the potential impact of these concepts, a holistic assessmentregarding technological, but also system level aspects is highly relevant. Against this backdrop, this talk will first provide an overview on aircraft electrification strategies and related technological implications, requirements and considerations. Then, their pertinence for different market segments will be examined, leading to a discussion of their possible impact on reducing aviation's overall footprint based on current flight and emission distribution. Finally, we will look at transition scenarios factoring in fleet penetration of different technological options, fuel alternatives and associated development rates. By shifting the perspective to 'the bigger picture' and deconvoluting individual contributions towards the envisaged carbon-neutrality of aviation, associated potentials of the above-mentioned electrified concepts can be holistically addressed.

   Development of electric motors for aircraft applications

Abstract: The trend toward the electrification of air transport is being driven by its positive contribution to amore sustainable future for aviation. Electric motors can help to increase efficiency, reduce emissions, and enable new concepts for the propulsion system of aircrafts. The various applications in the field of aviation place different requirements on the propulsion system and the electric machine. Here, the design of the electric machines is influenced not only by the required propulsion power itself, but also by the torque and speed, as well as the overall concept of the aircraft. A general requirement for powerful, efficient, and lightweight propulsion systems places high demands on the materials in terms of electromagnetic, mechanical, and thermal behaviour. High power and torque densities of motors, even at high efficiency, lead to high power dissipation densities in the different sub-areas of the machine, which leads to special cooling challenges.
