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 Improving the Efficiency of Engines for Large Nonfighter Aircraft written by National Research Council and published by National Academies Press. This book was released on 2007-08-30 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the important national defense contribution of large, non-fighter aircraft, rapidly increasing fuel costs and increasing dependence on imported oil have triggered significant interest in increased aircraft engine efficiency by the U.S. Air Force. To help address this need, the Air Force asked the National Research Council (NRC) to examine and assess technical options for improving engine efficiency of all large non-fighter aircraft under Air Force command. This report presents a review of current Air Force fuel consumption patterns; an analysis of previous programs designed to replace aircraft engines; an examination of proposed engine modifications; an assessment of the potential impact of alternative fuels and engine science and technology programs, and an analysis of costs and funding requirements.

Download or read book The Potential of Liquid Hydrogen as a Military Aircraft Fuel written by William T. Mikolowsky and published by . This book was released on 1976 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquid hydrogen does not appear to be attractive as a military aircraft fuel for the immediate future. In a wide variety of mission applications, liquid hydrogen is less cost-effective and less energy-effective than the available alternative. Indications are that synthetic jet-fuel is the most attractive alternative fuel for very large airplanes. At the least, this conclusion appears valid until coal reserves are substantially depleted. (Even for relatively high growth rates in coal consumption, domestic coal production is not likely to peak much before the second quarter of the 21st century). This conclusion is substantially strengthened when one realizes that airplanes using a conventional jet-fuel have the potential for a much greater payoff from advances in fuel-conserving aircraft technology. Furthermore, these conclusions prevailed despite our favorable assumptions toward liquid hydrogen in several important instances (e.g., aerial refueling). In summary, there is little, if any, potential for liquid hydrogen as a fuel for aircraft entering the Air Force inventory between now and the end of the century.

Download or read book Structures Technology written by Ahmed Khairy Noor and published by AIAA. This book was released on 1998 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawn from early volumes of Aerospace America and its antecedents, this book rescues the insights, concerns, and dreams of dozens of structural engineers for the next generation of aerospace scientists and engineers. Written by eminent individuals in structures, this book provides accessible source material for university-level design courses in aerospace engineering. The first paper in Structures Technology deals with new structures for future aerospace systems and provides a contrast between our current thinking and past technology plans. Succeeding papers are historical reports covering materials and structures, general structures technology, aircraft structures, space structures, and structural dynamics technology. You will also find sections covering structural configurations, thermal protection systems, subsonic aircraft, supersonic and hypersonic vehicles and structures for space systems.
