Book Description
The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Book Description
Propulsion Branch at ARL is reviewing the direction of its research activities into the integrity, durability and life extension of aircraft turbine engine components. Hot section repairs dominate the costs of engine overhaul, so resources are being redeployed from other programs on life of engine components toward this area of high potential benefit. Engine hot section life is an area of great complexity and wide scope. Despite the technical difficulties and limits in resources, the Branch can make a useful contribution with carefully selected research. New areas or extensions proposed are structural analysis of high temperature components under cycles of thermal loading, and thermal analysis of components to determine temperature distribution which characterises the thermo-mechanical loading. While structural analysis can build upon existing related expertise, little experience exists in thermal analysis and its core discipline of heat transfer, so a program to build up this technology base is proposed and options are examined.
