GE: Advancing Hybrid Electric Propulsion

Description: In 2021, GE joined NASAs Electrified Powertrain Flight Demonstration (EPFD) project. After years of developing individual components of a hybrid electric systemmotors, generators and power convertersGE will systematically mature a megawatt class (MW) integrated hybrid electric powertrain to demonstrate flight readiness for single-aisle aircraft. Plans are to conduct ground and flight tests of the hybrid electric propulsion system by the mid-2020s using a modified Saab 340B testbed and GEs CT7turboprop engines.
