Starting from the present standard of development of aero-engines for commercial aircraft, this paper first describes the reduction in fuel consumption and the improved economy attainable by maximization of the propulsive efficiency, namely through the use of future propfans and the shrouded propfan in particular. It then goes on to discuss the reduction in fuel consumption attainable with advanced-technology conventional core engines, i.e. those featuring high turbine entry temperature and high pressure ratio; in which admittedly the known factors regarding the production of pollutants, especially the emission of NOx during take-off and cruise, represent unfavourable starting conditions for the reduction of emissions. The paper finally shows how further reduction in the fuel consumption and increase in economy can be achieved over the longer term by recuperative core engines. It further points out how the very favourable preconditions for reducing pollutant emissions represents a significant contribution towards protecting the earths atmosphere.
