Tie-up eyes hybrid passenger aircraft
Print Edition
AIRBUS, Siemens and Rolls-Royce are teaming up to develop a hybrid passenger plane that would use a single electric turbofan along with three conventional jet engines running on aviation fuel.
The plane is an effort to develop and demonstrate technology that in the future could help limit emissions of carbon dioxide from aviation and reduce reliance on fossil fuels.
The three companies said yesterday they aim to build a flying version of the E-Fan X technology demonstrator plane by 2020.
The aircraft would be based on the existing BAe 146 four-engine regional jet. The hybrid version would generate electric power via a turbine within the plane. That power would be used to turn the fan blades of the single electric turbofan engine.
If the system works, a second electric motor could be added, the companies said.
They said European plane maker Airbus SE would be responsible for building the aircraft’s systems into a working whole, control systems and flight controls. Britain-based Rolls-Royce plc would make the generator and the turbo-shaft engine, while Germany’s Siemens AG would deliver the two-megawatt electric motor to power the engine. Rolls-Royce the aircraft engine maker is distinct from the luxury car brand owned by BMW AG.
The companies said they were looking ahead to the European Union’s long-term goals of cutting CO2 emissions from aviation by 60 percent.
