Download or read book Policy Options for the Aircraft Turbine Engine Component Improvement Program written by J. R. Nelson and published by . This book was released on 1987 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aircraft turbine engine Component Improvement Program (CIP) is an important element in the acquisition and maturation of engines for military aircraft and helicopter applications. This report presents the results of an investigation into the role of CIP, its value to the military services, and the feasibility and practicality of certain policy options including: 1) transitioning CIP to the private sector, 2) competing CIP in whole or in part, and 3) comparing CIP to airframe and avionics engineering change processes. Recommendations for future actions are included.

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.

Download or read book An Analysis of the Costs and Benefits in Improving F402 RR 406A High Pressure Turbine Second Stage Blades Under the Aircraft Engine Component Improvement Program CIP written by Donald Alan Walter and published by . This book was released on 1994 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is part of a continuing project at the Naval Postgraduate School attempting to validate the cost effectiveness of the Aircraft Engine Component Improvement Program. It focuses on the costs and benefits derived from Power Plant Change 159 which improved High Pressure Turbine, Second Stage blades on the Harrier (AV-8B) aircraft's Rolls-Royce Pegasus (F402-RR-F406A) engine. Because sufficient failure rate data for the improved blades was not available, the analysis considers a range of costs/benefits based on two different projected blade reliabilities. The improvement to the High Pressure Turbine, Second Stage blades was found to be cost-effective from both a financial break- even point, in that the cost to produce the improvement will be recovered by the end of 1996 for the full range of projected blade reliabilities and from a Net Present Value analysis which shows that this improvement will save the Department of the Navy between $17,192,827 and $38,639,494 (in 1992 dollars) over the projected life cycle of the engine.

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.

This book was released on 2007-07-30 with total page 192 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.
