The rapid rate at which the world's oil reserves are being used up, and the lack as yet of convenient substitute fuels at a competitive cost level, are leading to an increased emphasis on fuel economy in the design and operation of aircraft. This paper outlines technological advances that will contribute to the reduction of fuel consumption and attempts to give a broad indication of the overall improvements that may be achievable in relation to current technology. Since a companion paper is concerned specifically with work in the United States aimed at such objectives, attention is concentrated mainly on advances being made in the United Kingdom.
