Rolls-Royce has completed the first tests of its radical UltraFan geared engine design, the British aero-engine maker said Thursday during a special event held at its factory in Derby, UK. 

The UltraFan technology demonstrator will now pave the way for the manufacturer to start developing a scaled range of engines, using the technology to offer a portfolio of two-shaft, three-shaft, direct drive, and geared propulsion systems.
