Abstract

Abstract This chapter describes the noise and global warming effects produced by current commercial aircraft. It also describes noise and pollution sources, and proposes technologies to mitigate them.

The paper will then describe some estimates of the financial costs of aircraft pollution.

Significant environmental progress can only be made by more radical aircraft and engine configurations. A low-noise design methodology will be described, followed by results from using it to design a conventional baseline design, and a number of advanced low-noise designs. Particular attention will be given to the Broad Delta and blended-wing body designs. The paper continues with a description of the 50,000 man-hours post-grad group design A-6 Greenliner project. This is a long range 385 seat aircraft, which has been designed to be both quiet and to produce reduced atmospheric pollution. The A-6 is controversial, in that it is planned to fly at M =0.74, thus trading speed for environmental effects and costs. Lessons learnt from these projects will be summarized, and future plans discussed.
