Technology

Unlike our competitors, we do not attempt to electrify aircraft propulsion by replacing jet engines with electromagnetic motors that rotate a propeller. Instead, we electrify the jet engines themselves..

Our design is groundbreaking. Rather than burning fuel to heat the air within the jet engines, we utilize electricity to heat the air to temperatures exceeding 20,000°C, effectively converting it into plasma without emitting CO2.
This innovative electrothermal engine enables electric aircraft to reach unprecedented speeds including supersonic and hypersonic capabilities.

Applications

Key features

No CO2 emissions

Our engines solely heat the air without any combustion of fuel.
