MTU stops development of Water Enhanced Turbofan – focus on other technologies
MTU Aero Engines, a leading manufacturer of aircraft engines, has decided to stop the development of its Water Enhanced Turbofan (WET). This was reported by the trade magazine "Flug Revue" in its latest issue. According to MTU CEO Lars Wagner, the engine in the planned design did not achieve the desired fuel savings despite using all available technologies. Development of the engine will therefore be stopped in order to concentrate on other technologies that promise more potential for increasing efficiency. The decision to stop the WET project comes at a time when other companies in the aviation industry are facing similar challenges. Airbus and ATR recently announced that they would either pause or postpone their own plans for more climate-friendly aviation technologies. MTU is responding to these developments by adapting its strategy and intending to focus more on the use of thermal energy in the future in order to optimize the thermal cycle in aircraft engines. The Water Enhanced Turbofan: An Ambitious Project The Water Enhanced Turbofan was a promising technology that aimed to increase the efficiency of aircraft engines by injecting hydrogen or water. The theory behind the technology was that the addition of water vapor could lower the combustion temperature and thus reduce emissions of nitrogen oxides (NOx) and the formation of contrails. These technologies are of particular interest in terms of reducing the environmental impact of aviation. However, despite all the technological approaches and innovations, the WET engine fell short of expectations, especially in terms of fuel savings. The weight and size of the engine, says Wagner,
