NASA has chosen two U.S. companies to develop electric propulsion technologies for aircraft, with the aim of introducing this tech to U.S. aviation fleets by 2035.

The two companies, GE Aviation and MagniX, will conduct their work over the next five years. That includes ground and flight test demonstrations, as well as collaborations with other NASA projects focused on electric propulsion, data analysis and flight test instrumentation.
