Description: Das Projekt "Niedrigemissionsbrennkammer-Technik - niedriger NOx I" wird vom Umweltbundesamt gefördert und von Motoren- und Turbinen Union Friedrichshafen durchgeführt. Objective: The aim is to investigate and assess the pollution emissions of future aero-engines, covering small and large civil engines. This task is considered urgent, since increased pollutant emissions from aircraft are to be expected in future. General Information: Before reviewing the possible reduction methods, it will be necessary to perform a number of fundamental investigations, eg on fuel-air mixing and droplet formation. Definition of temperature and pressure conditions of future civil small and large aero engines. Assessment of the pollution emission of the defined engines using present combustor technology. Summary of methods which control the reduction of pollutants. Performing investigations into the fundamental formation processes of pollutants. These investigations will be carried out in relation to the phenomena of droplet formation and fuel-air mixing. The results help to review applicability of different pollution reduction methods. Selection of the most promising pollution reduction methods based on efficiency, reliability, safety, air worthiness, weight, volume and costs. Achievements: All three concepts showed potential in advanced low-emission aero engines, although they differ in the amounts of development investments they still require. For this reason, further investigations into emissions reduction methods are envisioned for the next project phase. Assuming that requisite fundamental work is carried out and a start is made on the development of appropriate combustors, referred to present levels, a 30 per cent reduction in the emission of nitrogen oxides by engines of the mid-nineties would appear feasible, and a reduction of 80 per cent should be possible by the end of the century. The achievement of these targets calls for investigation of both the combustion and combustor control aspects.
