Descripción del proyecto
Nuevas tecnologías para limitar las emisiones de NOx de los aviones
Mejorar la eficacia en el consumo de combustible y reducir las emisiones dañinas son algunos de los objetivos clave de los fabricantes de aeromotores, dado que constituyen una parte considerable de los costes de explotación de los aviones. El proyecto financiado con fondos europeos DENOX está trabajando en innovadores conceptos tecnológicos para recortar drásticamente las emisiones de óxido de nitrógeno (NOx) en los aeromotores de turbinas de gas. Los nuevos conceptos se centran en la eliminación electromecánica de la generación de NOx en la zona de combustión primaria y la descomposición electromagnética de las moléculas de NOx en el escape del motor. Si demuestran satisfactoriamente su efectividad y progresan a un nivel superior de preparación tecnológica, los conceptos de DENOX contribuirán a alcanzar el ambicioso objetivo de ACARE de reducir el NOx emitido por los aeromotores en un 90 % antes de 2050.
Objetivo
DENOX project aims to develop and experimentally prove two breakthrough technology concepts and their optimal combination for drastic reduction of NOx emissions in aeronautic gas-turbine engines (GTEs).
Technology concept 1 is electrochemical suppression of NOx generation in primary combustion zone. It consists in generation of modulated discharge(s) in combustion chamber to initiate chemical reactions competitive to conventional NOx generation mechanisms.
Technology concept 2 is electromagnetic decomposition of NOx molecules in engine exhaust. It consists in application of multi-frequency electromagnetic fields to the exhaust flow to ensure resonance excitation of chemical bonds in NOx molecules up to their dissociation.
DENOX technology concepts are underpinned by the results of KhAI’s theoretical investigations and numerical studies of high-temperature high-pressure low emission combustion processes, which demonstrated potential to decrease NOx concentration in exhausting gases on 20-95% without decreasing of engine efficiency.
The project will combine analytical studies and numerical simulations with experimental investigations and multi-level testing campaign to translate proposed technology concepts from TRL1 to TRL3 and to assess full potential of their combination for the next-generation GTEs.
DENOX outcomes will contribute to the advancement of aircraft engines in both (i) mid-term perspective (EIS 2035) through progress in understanding and modelling of high-temperature low emission combustion processes, and (ii) long-term perspective (EIS 2050) through the potential to drastically reduce NOx emissions to meet Clean Sky 2 High Level Objectives and ACARE SRIA goals.
