Bauhaus Luftfahrt, the foremost German aerospace research firm, have released information as to a design concept for a zero emission aircraft. The 190 seater airplane is set to be taxiing off runways by 2035.

The aircraft is named the Ce-Linar and the design showcases twin electric engines that takes its power from a bank of up to sixteen battery arrays. Bauhaus Luftfahrt forecasts that the batteries can power the plane up to 600 nautical miles or 1,110 kilometers of range. They also project that this battery design can be achievable by 2030.

Unfortunately, this aircraft can only cover nearly sixty percent of the routes in the 180 to 200 passenger aircraft sector. This is the category defined by experts as having the greatest potential for emissions reduction in the airline industry.

The company further declares that by 2035 the available technology would allow range extension of up to 900 nautical miles, which can then cover about 80% of market share. Should the unveiling of the aircraft be delayed to 2040, then the concept aircraft’s range can be extended to 1,400 nautical miles along with it improvements in aircraft configuration such as increasing aerodynamic efficiency through the ‘C-wing’ non-planar design. This configuration would be able to increase performance without sacrificing wingspan limitations.

The German design firm says that this concept goes ‘far beyond’ all current designs for all-electric flight concepts. The statement further states, “Recharging the batteries during turnaround is postulated to remain challenging, hence an exchange after each flight is assumed.” Other innovations include electric motors and power transmission wirings that would require high-temperature superconductor technology to allow an increase in available power to weight rations crucial for the plane’s ability to lift itself off the ground.

Other aircraft projects in the pipeline for Bauhaus Luftfahrt is the Claire Liner. This design uses clean air box wing concepts that provide extreme short take off capability through the use of laminar airflow and wing fan integration. This design would be undertaken in partnership with IABG, Germany’s foremost aeronautical testing organization. Other partners include EADS, Liebherr Aerospace, MTU Aero Engines and the Bavarian Ministry of Economics.
