Exhaust Emissions From Gas Turbine Aircraft Engines

The development of clean, sustainable energy systems is a preeminent issue in our time. Gas turbines will continue to be important combustion-based energy conversion devices for many decades to come, used for aircraft propulsion, ground-based power generation, and mechanical-drive applications. This book compiles the key scientific and technological knowledge associated with gas turbine emissions into a single authoritative source.

Works related to identification of harmful exhaust components from aviation engines have continued since the second half of the last century. These works focus on high-thrust turbine engines. For this, group testing and standardization procedures have been developed containing the admissible limits of exhaust components. Since 2007 works have been underway related to the identification of harmful exhaust components from engines of low power output that have not yet been included in the emissions legislation. These actions are particularly related to the measurements of the exhaust emissions from piston aviation engines and they are focused on the fuel applied for these engines. This book presents the results of the author's own research work related to the issues of exhaust emissions from powertrains of aircraft and helicopters fitted with piston or turbine engines not yet included in the emission legislation. Research has been presented for turbocharged piston and jet engines aircraft. Test procedures have been presented related to the measurement of the exhaust emission under actual conditions of operation. The study presents analyses of the operating conditions of aviation engines, for which data from the on-board recording devices (flight parameters) have been used. Tests have been developed related to the engines operating under actual operating (in-flight) conditions. The methodology of the developed test has been validated based on a test dedicated for an aircraft fitted with a jet engine. The test results have been subject to a comparison with the results of tests applicable in the homologation procedures. Eventually, the authors proposed exhaust emissions tests dedicated to individual aircraft groups.

Exhaust Emissions Standards - New Aircraft Gas Turbine Engines and Identification Plate for Aircraft Engines (US Federal Aviation Administration Regulation) (FAA) (2018 Edition) The Law Library presents the complete text of the Exhaust Emissions Standards - New Aircraft Gas Turbine Engines and Identification Plate for Aircraft Engines (US Federal Aviation Administration Regulation) (FAA) (2018 Edition). Updated as of May 29, 2018 This action amends the emission standards for turbine engine powered airplanes to incorporate the standards promulgated by the United States Environmental Protection Agency (EPA) on June 18, 2012. This amendment fulfills the FAA's requirements under the Clean Air Act Amendments of 1970 to issue regulations ensuring compliance with the EPA standards. This action revises the standards for oxides of nitrogen and test procedures for exhaust emissions based on International Civil Aviation Organization standards, and for the identification and marking requirements for engines.

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.

This volume documents the proceedings of the Symposium on Emissions from Continuous Combustion Systems that was held at the General Motors Research Laboratories, Warren, Michigan on September 27 and 28, 1971. This symposium was the fifteenth in an annual series presented by the Research Laboratories. Each symposium has covered a different technical discipline. To be selected as the theme of a symposium, the subject must be timely and of vital interest to General Motors as well as to the technical community at large. For each symposium, the practice is to solicit papers at the forefront of research from recognized authorities in the technical discipline of interest. Approximately sixty scientists and engineers from academic, government and industrial circles in this country and abroad are then invited to join about an equal number of General Motors technical personnel to discuss freely the commissioned papers. The technical portion of the meeting is supplemented by social functions at which ample time is afforded for informal exchanges of ideas amongst the participants. By such a direct interaction of a small and select group of informed participants, it is hoped to extend the boundaries of research in the selected technical field.
