A low-pressure compressor, integrated into an aeronautic engine fan module, has successfully completed a seven-week test programme as part of the European Union's Environmentally Friendly Aero Engines (Vital) programme.
US-European joint venture Techspace Aero and the Moscow-based Central Institute of Aviation Motors carried out the low- and high-speed rotation tests.
They say the fan module aims to reduce aircraft engine noise and carbon dioxide emissions by making the low-pressure compressor more compact and lighter by improving aerodynamics.
The new technology will now be embedded in engines being developed under the Leap X programme carried out by CFM International, which aims to drastically reduce fuel burn.
Techspace Aero is 56%-owned by Safran, a CFM parent company. Other Techspace shareholders are Belgium's Federal Investment, Pratt & Whitney and the Walloon region.
