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 An Analysis of the Costs and Benefit in Improving the T56 A 427 Interconnector Harness End and Mating Thermocouple End Connector Under the Aircraft Engine Component Improvement Program CIP written by Thomas Joseph Murphy and published by . This book was released on 1994 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a study validating the cost effectiveness of the Component Improvement Program for aircraft engines. It determines the costs and benefits derived from the Navy incorporating Power Plant Change 111 which improved the interconnector harness end and mating thermocouple end connector of the T56-A-427 engine. Useful maintenance data pertaining to this component was extracted from the Naval Logistics Data Analysis (NALDA) system. Cost data pertaining to the Power Plant Change was taken from two sources, the Manufacturer's Engineering Program Description (EPD) and the Naval Air System Command's Configuration Change Control Board (CCCB) document. Based on the author's analysis, the improvement to the interconnector harness end and mating thermocouple end connector was cost-effective from both a financial break-even point in that the cost to produce the improvement will be recovered after three years, and from a Net Present Value analysis on this improvement which shows that the U.S. Navy will save more than $400,000 during the expected fifteen-year life cycle of the engine.

This book was released on 1992 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a study of the J52 Engine Component Improvement Program (CIP). The objective of the thesis was to determine if the correlation between J52 CIP expenditures and improved maintenance parameters at the component level could be quantified. The major focus of the study revolved around developing a methodology to accomplish the objective using existing databases and open dialogue between the J52 engine manufacturer (Pratt and Whitney), NAVAIRSYSCOM Engine Program Manager, and various NADEP engineers. The methodology evolved using the Fuel Nozzle Support Assembly and was validated using the Fuel Pump. The thesis reached the conclusion that observed improvements in maintenance parameters can be linked to CIP expenditures at the component level.

This book was released on 1975 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was scoped to look at the CIP for military aircraft engines. With an eye toward where it has been in the past, various agencies have looked at CIP to determine how it can be done better. These studies were looked at and analyzed, and the question baseline was pinpointed to the contracting function. The need to conserve dollars is a driving function, but the engine need to perform for longer periods in longer time between overhaul is equally important. At issue also is how the Government can better control the contract's effort through a higher degree of visibility to management in both engineering and funding.

This book was released on 1987 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to identify if the data collected by Turbine Engine Monitoring Systems (TEMS) could benefit an engine's Component Improvement Program (CIP) management. The initial plan was to identify and assess any benefits by comparing an engine with a CIP (PWA TF30) but not TEMS against an engine with a CIP and a TEMS (GE TF34). This was not possible, however, because the TEMS data were not being used to assist with TF34 CIP management because of the lack of a Central Data Base to collate and transform the data. The engine duty cycle was identified as the key to many important areas of a CIP, including engine component life usage and failure replication and diagnosis. As mentioned in the previous paragraph, the current methods used to identify as engine's duty cycle lack the accuracy and reliability that are required to manage modern gas turbine engines. The main thrust of the recommendations is that a central data base be established so that the TF34 CIP manager can utilize TEMS data. In addition, a comparison using cost analysis is recommended to firmly establish the benefits to both long and short term engine management. Keywords: Theses; Aircraft engines.

This book was released on 1991 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines the cost-effectiveness models used by the Air Force and Navy to assist with the decision-making process of their Component Improvement Programs (CIP). The focus on the elements of the two models and the reasonableness of each model's results. A sensitivity analysis was performed on significant input parameters to determine what effect errors in these parameters would have on the predicted return-on-investment (ROI) results. The author concluded that, although the models provide insight into life cycle costs (LCC) of aircraft engines, they are extremely sensitive to errors in certain input variables and should not be relied upon for CIP budget justification.

This book was released on 2018-06-12 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of the small engine technology study task is to identify key, enabling jet engine component technologies for improved performance, primarily for commercial, regional subsonic aircraft. The study involved two regional engine applications: the CF34 turbofan engine, which is installed on a regional jet application and the CT7-9 turboprop, which is installed on regional turboprop applications. Technologies to improve the performance of these applications were identified. Estimates of the benefits and development costs for each technology were made. Performance sensitivities were calculated for each of the technology items identified. The technology improvements were then translated into component improvements and their impact on the aircraft economics was evaluated. A factor of merit based on sfc was calculated as the percent improvement in sfc times the probability of improvement divided by the development evaluation costs associated with that technology item. The technologies were ranked for both the turbofan and turboprop applications.Gregory, Brent B. and Eisenberg, Joseph D.
