Simulation software in sustainable aviation: from hybrid electric to hydrogen electric aircraft

The most promising opportunities to improve aircraft efficiency and overall sustainability are in electrified propulsion concepts. These are designed and assessed virtually using simulation software. Here, the right amount of detail is required to allow informed decision making. However, it is slow and expensive to introduce superfluous detail. This presentation summarizes some typical choices in representing key components of propulsion concepts ranging from hybrid electric to hydrogen electric aircraft, and describes how their strengths and limitations cascade to aircraft-level projections.
