HORIZON-JU-CLEAN-AVIATION-2026-04-SMR-03 - Ground Demonstration of Hybrid-Electric Propulsion Architectures for the Ultra-efficient SMR aircraft

Expected Outcome:Development and demonstration of hybrid-electric propulsion architectures for the Ultra-Efficient SMR aircraft. This topic covers the demonstration of hybrid-electric sub-systems integrated into ducted or unducted engines at TRL5 through ground demonstrations with an aim to demonstrate the benefits from such propulsion architectures targeting at least 5% CO2 emissions reduction at aircraft level, with a clear roadmap towards TRL6 by 2030 supporting a future product launch compatible with an EIS by 2035. See the topic description document published with this call for full details.
