Abstract
This paper first describes the existing and the anticipated requirements to be met by commercial aircraft engines and discusses them with a view to the development work and measures considered necessary to effectively protect the earth’s atmosphere.
Then the present level of pollutant emissions attained with today’s engines is explained taking the CF6–50C engine as an example. Furthermore this paper outlines the development potential of future engines for subsonic commercial aircraft with respect to a reduction of the specific fuel consumption and the specific pollutant emission. In this connexion, possible future emission levels attainable with kerosine, methane and hydrogen are compared.
The reduction of specific fuel consumption and specific pollutant emission achievable with the aid of new technologies are set against the expected development in air traffic and the resulting tendency towards an increase in the fuel consumption by commercial aircraft worldwide. This comparison shows that a perceptible lessening of the impact on the atmosphere in and above the tropopause is possible only in the long run provided the specific fuel consumption as well as the specific pollutant emissions of engines can be drastically reduced.
