Prof. Dr. Frank Brückner, Mirko Riede and Dan Roth-Fagaraseanu (Rolls-Royce) has succeeded in increasing the stability of those aircraft engine parts which are subject to stress due to temperature. The IWS process helps to reduce kerosene consumption as well as CO2 emissions.
(Dresden, September 12, 2018) Dresden Fraunhofer engineers are working on reducing the fuel consumption of cars by more than a tenth. They use ultra-short laser pulses to generate very fine and friction-reducing fishbone patterns in engines.
(Dresden, August 8, 2018) Filigree engravings on external surfaces of aircraft are intended to ensure that airflow remains smooth and drag on the aircraft low. For this, engineers at the Fraunhofer Institute for Material and Beam Technology IWS, the Technische Universität Dresden and Airbus have developed a laser process that produces textured surfaces at high throughput making surface contamination more difficult.
Joseph von Fraunhofer Prize 2018: Improved efficiency of aircraft engines
The Fraunhofer Institute for Material and Beam Technology IWS has succeeded in increasing the stability of those aircraft engine parts which are subject to stress due to temperature. The IWS process helps to reduce kerosene consumption as well as CO2 emissions. In combination with further measures, significant cost savings result during flight operations. The research project was developed in close cooperation with the engine specialist Rolls-Royce. The first engines with the new technology are already in use.
Engineers at the Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS in Dresden have developed an innovative process in cooperation with industrial partners to weld and form modern lightweight parts for aircraft. They present this technology at the International Aerospace Exhibition ILA in Berlin from 25 to 29 April 2018.
