Nieuw vliegtuigmotoren design om CO2 emissies te reduceren
Speaking at a meeting of NEWAC partners in Munich in July 2010, the European Commission's Deputy Head of Aeronautics Research Daniel Chiron explained that new engine technologies can help bring emissions down: "Of course, the amount of emissions being generated by aircraft engines depends on how those engines work, how they are designed. Clearly, alternative and innovative engine configurations need to be investigated."
New technologies to cut emissions
NEWAC project coordinator Stephan Servaty of MTU Aero Engines says, "Our goal has been to fully validate novel technologies enabling a 6% reduction in CO2 emissions and a 16% reduction in nitrogen oxide (NOx). Now, after some four years of intensive collaborative research, these goals have nearly been achieved."
NEWAC brought together 40 organisations, including the major European engine manufacturers, small and medium-sized enterprises, and universities and research centres, who investigated four new, highly technical and highly innovative core engine configurations.
Leaner and cleaner
"We and our partners developed and tested lean-combustion concepts for very low NOx emissions," says Servaty. "In addition, we conducted intensive test runs with compressors and novel, active control systems to improve stability and efficiency, yielding very promising results, and we designed more efficient and lightweight compressors."
"The success of this project is indisputable," says Chiron. "Although the business case for their introduction in commercial operations still has to be made, that should not be so complicated. This is a situation where what's good for society – cleaner and more efficient air transport – is also good for business."
