Future reductions of fuel burn and green house gas emissions from commercial aviation will be, in large part, achieved through the development and use of more fuel- and environmentally-efficient aircraft. Achieving significant efficiency improvements at the aircraft level may require opening up the design space so as to consider changes in aircraft design mission specifications/capabilities such as lower cruise speed, different payload-range characteristics, and longer wing span. However, there are potentially serious and unforeseen system-wide implications (economics, viability, delays, manufacturability, etc.) that could result from these changes and that have not yet been quantified properly. The main objective of this project is to understand and quantify these implications so that informed decisions can be made. |
