Fail-Safe Hybrid Electric Propulsion System Design for Aircraft

The aerospace industry is on the edge of a new era. The industry is exploring new fully-electric and hybrid-electric propulsion systems to comply with the latest environmental regulations and reduce fuel burn.

However, electrification at this scale brings new technological challenges and trade-offs. The viable powerplant will trade-off the range, battery capacity, motor power density, and thermal management.

The complexity of these propulsion architectures requires a holistic, multi-disciplinary development approach. We'll explore how interoperable Ansys tools can work together to consider the optimized architecture,  undertake a safety analysis, use multi-physics simulation and embedded software design to validate, and then automate safe controls. This toolchain will be needed to efficiently design a product that will meet performance goals and provide supporting evidence for certification and product and passenger safety.

There are many concerns related to the safety of batteries, specifically on how to keep them cool and prevent onboard fire. The webinar covers a regional transport aircraft's system-level functional safety analysis and hybrid-electric power architecture. It showcases how having an alternate source of power provides a backup method for a safe emergency landing in the event of batteries failure.
