The environmental impact of air travel—noise, airport pollution, and high‑altitude emissions—will increasingly constrain aircraft design and limit future growth unless per‑passenger kilometres are substantially reduced. The lecture reviews the Air Travel – greener by Design programme’s work and urges aerodynamicists, with support from structures, systems, and materials engineers, to champion a radical design leap to reduce these impacts. The authors evaluate technological, design, and operational options identified by the programme to lower noise, pollution, and climate effects. Pursuing these opportunities could make aircraft in production in 2050 markedly different from those of 2005.
Abstract In the coming century, the impact of air travel on the environment will become an increasingly powerful influence on aircraft design. Unless the impact per passenger kilometre can be reduced substantially relative to today’s levels, environmental factors will increasingly limit the expansion of air travel and the social benefits that it brings. The three main impacts are noise, air pollution around airports and changes to atmospheric composition and climate as a result of aircraft emissions at altitude. The lecture will review the work done within the Air Travel – greener by Design programme to assess the technological, design and operational possibilities for reducing these impacts. The main aeronautical disciplines all have something to contribute but it is in aerodynamics that the greatest opportunities appear to lie. If these opportunities are pursued, the aircraft in production in 2050 could be very different from those of 2005. It is for the aerodynamicists, supported by the structures and systems engineers and the materials scientists, to make the case for a radical leap.
