GE: Advancing Hybrid Electric Propulsion

Description: In 2021, GE joined NASA’s Electrified Powertrain Flight Demonstration (EPFD) project. After years of developing individual components of a hybrid electric system—motors, generators and power converters—GE 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 GE’s CT7turboprop engines.

See what we are doing today for the benefit of us all tomorrow:

"All we need now is 4 trillion dollars and 40 more years of development!" - GE, probably

Show us the NUMBERS, guys. Do they make ANY sense at

[rajatdani]

Ge has Challenged Laws of Thermodynamics..😃

From washing machines to ION propulsion

Intresting... but the added weight is worth it?

It's here. We need to do hybrid before finally going full electric

There's been Electric RC airplanes for a long time, but it's going to be a LOT of battery power required to power a commercial jet for any distance.
Like it or not, Fossil Fuels POWERS OUR ECONOMY for the foreseeable future, and while it's GOOD to develop new avenues of Energy and "Clean" machinery, it's NOT "GOOD" to DESTROY the Economy on the PROMISE of "Going Green" when the REALITY is it's still a LONG WAY off.

the video editing is manic. the music is too loud and over dramatic and the 3d rotation is distracting

So it's an hybrid motorjet.
Except this one stores energy for later. But that energy needs to come from somewhere. Oh yeah... The turbines. So you gain extra power for takeoff and climb out. So your turbines can be smaller. But they work harder during cruise to charge the battery and haul the added weight of battery, motors, cables and regulators.
You'd be better off with a regular motorjet. Or as they're calling them now "compound jet" which makes sense. Studies show a 15-20% fuel savings over turbines.
