The environment as the key design driver in aeronautics
D.I.A. Poll, Cranfield University, UK
The aviation industry has the potential to make a significant contribution to the level of carbon dioxide in the atmosphere and to introduce short-term perturbations to other contributors to the Earth’s radiation balance. There is a direct link between the economics of aviation and its environmental impact. From the Bréguet range equation, nine theorems relating to aspects of an aircraft’s energy liberated to revenue work ratio (ETRW) are derived, the ratio becoming large when distances flown are small. The ETRW for aircraft in service is estimated and the best aircraft from an environmental impact point of view identified. The effect ...
