Electrified Powertrain Flight Demonstration (EPFD) Project Executive Summary

The Electrified Powertrain Flight Demonstration (EPFD) project, under NASA’s Integrated Aviation Systems Program (IASP), selected GE Aerospace and magniX as cost-share partners to mature and flight demonstrate MW-class hybrid electric aircraft propulsion systems.

Both companies elected to demonstrate on large regional turboprop aircraft their hybrid electric architectures. These Part 25 transport category aircraft provided the necessary size, performance, and operational profile for effective demonstration of their MW-class powertrain architectures through retrofit modifications. EPFD’s focus on crewed demonstrations marked a strategic advancement beyond prior EAP efforts. By addressing the aviation environment and practical vehicle-level integration barrier risks, as well as achieving reductions in fuel burn, emissions, and operational costs, this effort will accelerate the regulatory and certification pathways to enable future Entry into Service (EIS) of hybrid electric aircraft.
