This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Generalized Approach to the Selection of Propulsion Systems for Aircraft written by L. R. WOODWORTH and published by . This book was released on 1951 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The generalized approach considers the powerplant in terms of the performance and application requirements of the aircraft. A powerplant choice for a given combination of these requirements represents a compromise between powerplant weight, frontal area, and fuel consumption. Parameters relating to the performance and application requirements of aircraft are used in simplified endurance equations, which encompass a broad range of applications, in combination with powerplant characteristics. By use of electronic calculating equipment, systematic evaluation of each powerplant type and variation within type is established for each selected combination of aircraft performance and application requirements. The powerplant is selected on the basis of maximum endurance which, under the method used, is equivalent to minimum total weight of powerplant plus fuel weight. The powerplant spectrum is represented by seven powerplant types; Rocket, Ram Jet, Afterburning Turbojet, Turbojet, Ducted Fan, Turboprop with varying power division between propeller and jet, and Reciprocating. Effects of compressor pressure ratio and turbine inlet temperature on the characteristics of the gas turbine family are considered. (Author).

This book was released on 2007-01-14 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rocket and air-breathing propulsion systems are the foundation on which planning for future aerospace systems rests. A Review of United States Air Force and Department of Defense Aerospace Propulsion Needs assesses the existing technical base in these areas and examines the future Air Force capabilities the base will be expected to support. This report also defines gaps and recommends where future warfighter capabilities not yet fully defined could be met by current science and technology development plans.

This book was released on 2003-12-18 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: As recently as the summer of 2001, many travelers were dreading air transportation because of extensive delays associated with undercapacity of the system. That all changed on 9/11, and demand for air transportation has not yet returned to peak levels. Most U.S. airlines continue to struggle for survival, and some have filed for bankruptcy. The situation makes it difficult to argue that strong action is urgently needed to avert a crisis of undercapacity in the air transportation system. This report assesses the visions and goals for U.S. civil aviation and technology goals for the year 2050.
