Airbus, Rolls-Royce, Siemens to make hybrid-electric aircraftStaff Writer | November 28, 2017
Airbus, Siemens and Rolls-Royce announced a collaborative effort on Tuesday to develop a hybrid-electric airplane engine.
Technology Environmental goals of the European Commission
If successful, the companies would then try to replace a second engine.
Airbus will be responsible for the overall integration of parts made by Rolls-Royce and Siemens for the aircraft propulsion systems, the companies said. Siemens will build the two-megawatt motor and Rolls-Royce will construct the generator.
A short-haul plane with four electric engines requires about 20 megawatts to operate safely, Airbus said.
The project is motivated by environmental goals of the European Commission calling for a 75 percent reduction in aircraft-generated carbon dioxide emissions by 2050.
The commission guidelines also call for a 90 percent reduction in nitrogen oxides and a 65 percent decline in noise pollution. ■
