B -- EVALUATION OF JET AVIATION EMISSIONS SOL 2339091 DUE 100697 POC Mekeba Brown, Contract Specialist, 202-564-4784 Statement of Work: BACKGROUND: The Environmental Protection Agency (EPA), Office of Atmospheric Programs (OAP), is evaluating the effects of jet aircraft emissions and models for high speed transport on both the lower stratosphere and the upper troposphere. Jet aircraft at cruise altitude inject emissions directly into the free troposphere. Information reviewed to date indicates that the oxides of nitrogen (NOx) emitted from jet aircraft may significantly contribute to ozone formation in the upper troposphere and high speed transport may contribute to ozone depletion in the stratosphere. Significant issues that require further investigation include the fuel use and NOx trade-off issues based on engine designs for both projected growth versions of current engines such as the "throttle push" versions of today's large thrust, high pressure ratio engines, as well as the next generation of higher pressure ratio engines that are under development. In order to conduct this further investigation, the OAP requires contractor support. This support must be based upon extensive experience, nationally and internationally, in the combustion system research, design, analysis, and development of aircraft engines, particularly the development and application of emission abatement technology. TASK 1: The contractor shall review information including numerous documents developed by and for the International Civil Aviation Organization's Committee on Aviation Environmental Protection, relevant reports and working papers by AERNOX, NASA, FAA, ICCAIA, DLR, DERA, Air Canada, Pratt & Whitney, General Electric, Rolls Royce, Boeing, and McDonald Douglas. Based on this information and on the consultant's personal expertise, the contractor will develop a report concerning the fuel use and NOx tradeoff issues based on engine designs. Specifically, the contractor will provide information concerning the potential for more stringent NOx requirements to degrade the fuel economy of both projected growth versions of current engines such as the "throttle push" versions of today's large thrust, high pressure ratio engines, as well as the next generation of higher pressure ratio engines that are under development. This working paper will consider throttle push engines, and any potential adverse fuel economy effects for 5%, 10%, 15%, and 20% NOx stringency increases, particularly, the effect for engines that may not currently meet these more stringent levels. This working paper will: 1) consider whether combustor design modifications can reasonably be expected to improve NOx performance without degrading fuel consumption, and 2) include an evaluation of whether stringency standards are an economic issue rather than an issue of the technical ability for both NOx and fuel economy. This working paper will also include an assessment of the role the competitive market place plays in improving fuel efficiency, thus reducing CO2 emissions. Furthermore, the working paper will evaluate whether these same competitive market place influences can influence NOx emission reductions. The working paper will consider the potential for the drive to improve fuel efficiency result in a reduction of NOx emissions. In addition, the role of operational measures for reducing both NOx emissions and improving fuel economy will be assessed. The working paper will include a section that assesses the success with the next generation of engines that already achieve low NOx levels. Where this is coupled with reasonably expected improvements in engine cycles, materials, and combustor technology, the working paper will evaluate the expectation for improved fuel economy. In addition, the working paper will assess improved fuel economy in the context of still maintaining a conventional combustor and/or incorporating a double annular/ axially staged combustor. Include information concerning the potential introduction of increased NOx stringency standards. Finally, the working paper will include information concerning the NASA Advanced Subsonic Technology (AST) program and its stretch goals to reduce emissions. Deliverable Due Date: Draft Working Paper -- October 15, 1997 Final -- Within two weeks of receiving written comments from EPA TASK 2: The contractor shall participate in a workshop on high speed civil transportation (HSCT) scheduled for October 23, 1997, in Washington, D.C., and shall review industry information provided at the workshop. Work shop participants will include industry stakeholders, representatives of non-government organizations, and representatives of federal agencies (including but not limited to EPA, FAA, NASA, and NOAA). Subsequently, the contractor shall draft a memo discussing the likely scenarios for engines designed for the HSCT. In particular, discuss the reasonably expected levels of emissions, particularly CO2 and NOx. Discuss the reasonableness of fuel efficiency designs. Include information concerning the NASA High Speed Research (HSR) program and its stretch goals to reduce emissions. Deliverable due date: Draft memo -- January 12, 1998 Final -- within one month of receiving written comments from EPA All deliverables for Tasks 1 and 2 shall be delivered in hard copy and on a 3.5 in. disk in WP 6.1. SELECTION CRITERIA EXCLUSIONS: Excluded from consideration are companies and individuals currently employed by an airline company, airline engine or airframe manufacturer, a related trade association, and related government entities including, but not limited to, NASA and DOT.
