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 Air breathing Engine Test Facilities Register written by North Atlantic Treaty Organization. Advisory Group for Aerospace Research and Development and published by . This book was released on 1981 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: In context with its Symposium on 'Turbine Engine Testing' it has been the aim of the Propulsion and Energetics Panel of AGARD to offer to the NATO community a survey on air-breathing engine test facilities which are presently available in NATO countries. It was concluded that the main interest is focussed on test facilities for research and development of aero-engines to be used as prime thrusters. Consequently production and post-overhaul acceptance test facilities are not to be found in this register, even though in some cases they have been used for special investigations. In this book the reader will find a fairly complete survey of organizations which operate altitude and sea level test facilities for turbo-jet (including turbo-fan), ram-jet, and turbo-shaft engines. Though the book cannot claim comprehensiveness its initial working title was kept but the word register should not be understood in its prime sense and official meaning. Summary information about the test capacity of organizations and more detailed data for a number of individual test cells are offered and may be used for quick comparison and survey or for a preliminary selection of test facilities which the reader may wish to use in his research and development programmes.

Download or read book Jet Propulsion written by N. A. Cumpsty and published by Cambridge University Press. This book was released on 2003-08-14 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second edition of Cumpsty's excellent self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engines. Through two engine design projects, first for a new large passenger aircraft, and second for a new fighter aircraft, the text introduces, illustrates and explains the important facets of modern engine design. Individual sections cover aircraft requirements and aerodynamics, principles of gas turbines and jet engines, elementary compressible fluid mechanics, bypass ratio selection, scaling and dimensional analysis, turbine and compressor design and characteristics, design optimization, and off-design performance. The book emphasises principles and ideas, with simplification and approximation used where this helps understanding. This edition has been thoroughly updated and revised, and includes a new appendix on noise control and an expanded treatment of combustion emissions. Suitable for student courses in aircraft propulsion, but also an invaluable reference for engineers in the engine and airframe industry.
Download or read book Joint US Russia TU 144 Engine Ground Tests written by Waldo A. Acosta and published by . This book was released on 1997 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two engine research experiments were recently completed in Moscow, Russia using an engine from the Tu-144 supersonic transport airplane. This was a joint project between the United States and Russia. Personnel from the NASA Lewis Research Center, General Electric Aircraft Engines, Pratt & Whitney, the Tupolev Design Bureau, and IBP Aircraft LTD worked together as a team to overcome the many technical and cultural challenges. The objective was to obtain large scale inlet data that could be used in the development of a supersonic inlet system for a future High Speed Civil Transport (HSCT). The first experiment studied the impact of typical inlet structures that have trailing edges in close proximity to the inlet/engine interface plane on the flow characteristics at that plane. The inlet structure simulated the subsonic diffuser of a supersonic inlet using a bifurcated splitter design. The centerbody maximum diameter was designed to permit choking and slightly supercritical operation. The second experiment measured the reflective characteristics of the engine face to incoming perturbations of pressure amplitude. The basic test rig from the first experiment was used with a longer spacer equipped with fast actuated doors. All the objectives set forth at the beginning of the project were met.

Download or read book Decision Support Model to Evaluate Methods for Reducing Air Pollution Emissions During Jet Engine Testing written by and published by . This book was released on 1995 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Air Force operates more than 6,800 aircraft that use more than 15,700 turbine engines. Whenever these engines are in operation they generate pollution. The majority of the pollution is composed of five air toxics: Particulate Matter, Carbon Monoxide, oxides of Nitrogen, Oxides of SulAir, and Unburned Hydrocarbons. Currently, the emissions from these engines are not regulated while the engines are in use in military aircraft. However, during the periodic maintenance and repair of aircraft turbine engines, maintainers must test the engines' operation at each power setting. Emissions during these tests are permitted under Title V of the Clean Air Act Amendments of 1990. Because the Air Force has a large number of both engines and engine test facilities, future regulations based on current law have the potential to severely affect the Air Force engine testing program. This research uses decision analysis to clarify issues surrounding the question: How can Air Combat Command effectively test its jet engines and still comply with the environmental requirements of the Clean Air Act as amended in 1990? To answer this general question, the research objectives of this study were: (1) Perform a review of modern jet engines and the emissions that result from jet engine testing. This review focused on the underlying causes of emissions and potential methods to reduce these emissions; (2) Construct a decision model to compare the various existing and potential methods for meeting Clean Air Act regulatory requirements during jet engine testing in ACC; (3) Use this model to compare the costs and benefits of various notional methods for meeting regulatory requirements by reducing emissions during the testing of Air Combat Command's jet engines. These notional methods were based on the technologies uncovered during the literature review. (AN).

The airflow of 285 lb/sec (129.4 kg/sec) at 1200' F (922 K), 115 psia (79.2 N/cm2), and 60 000-ft (18 240-m) altitude exhaust capability allows simulation of combustor inlet conditions over most of the range of interest in supersonic cruise engines. Description of a unique jet-engine-fired, nonvitiating air heater is included. The test section, the instrumentation, the data acquisition system, and operation techniques and experiences are also described.
Download or read book Fundamentals of Jet Propulsion with Applications written by Ronald Flack and published by . This book was released on 2005 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: This introductory 2005 text on air-breathing jet propulsion focuses on the basic operating principles of jet engines and gas turbines. Previous coursework in fluid mechanics and thermodynamics is elucidated and applied to help the student understand and predict the characteristics of engine components and various types of engines and power gas turbines. Numerous examples help the reader appreciate the methods and differing, representative physical parameters. A capstone chapter integrates the text material into a portion of the book devoted to system matching and analysis so that engine performance can be predicted for both on- and off-design conditions. The book is designed for advanced undergraduate and first-year graduate students in aerospace and mechanical engineering. A basic understanding of fluid dynamics and thermodynamics is presumed. Although aircraft propulsion is the focus, the material can also be used to study ground- and marine-based gas turbines and turbomachinery and some advanced topics in compressors and turbines.
