What Happened

Federal Funding Boosts Development of ES-36 Electric Aviation Technology

The Federal Aviation Administration has selected Heart Aerospace for a $2.9 million CLEEN award to advance the ES-36’s hybrid-electric propulsion system. With an equal investment from Heart, the award supports a $5.8 million project to develop and test a megawatt-class turbogenerator. This technology aims to extend the ES-36’s range beyond battery power alone, enabling all-electric and longer-range hybrid-electric flight. The award builds on the FAA’s earlier support for Heart’s powertrain through its FAST program, as reported by an unknown source.
