Download or read book An Analysis of the Correlation Between the J52 Engine Component Improvement Program and Improved Maintenance Parameters written by and published by . 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.

Download or read book Predicting Jet Engine Component Wear to Enable Proactive Fleet Maintenance written by Eamonn Samuel Shirey and published by . This book was released on 2019 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principle driver of maintenance costs for commercial jet engines is the replacement of components that, upon inspection, are determined to be damaged beyond their repairable limits. In order to better predict the lifetime cost of maintaining engines through its flight hour agreement program, Pratt & Whitney aims to predict the probability of needing to replace these parts using information about how an engine has been used. Using historical repair records, we study a suite of statistical models and evaluate their performance in predicting part replacement rates. Despite a preference for interpretable models, we conclude that a random forest approach provides drastically more accurate predictions. We also consider the wider business implications of improved part replacement predictions, particularly as they pertain to forecasting material requirements and reducing volatility upstream in the supply chain.

Download or read book Critical Component Wear in Heavy Duty Engines written by P. A. Lakshminarayanan and published by John Wiley & Sons. This book was released on 2011-09-07 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The critical parts of a heavy duty engine are theoretically designed for infinite life without mechanical fatigue failure. Yet the life of an engine is in reality determined by wear of the critical parts. Even if an engine is designed and built to have normal wear life, abnormal wear takes place either due to special working conditions or increased loading. Understanding abnormal and normal wear enables the engineer to control the external conditions leading to premature wear, or to design the critical parts that have longer wear life and hence lower costs. The literature on wear phenomenon related to engines is scattered in numerous periodicals and books. For the first time, Lakshminarayanan and Nayak bring the tribological aspects of different critical engine components together in one volume, covering key components like the liner, piston, rings, valve, valve train and bearings, with methods to identify and quantify wear. The first book to combine solutions to critical component wear in one volume Presents real world case studies with suitable mathematical models for earth movers, power generators, and sea going vessels Includes material from researchers at Schaeffer Manufacturing (USA), Tekniker (Spain), Fuchs (Germany), BAM (Germany), Kirloskar Oil Engines Ltd (India) and Tarabusi (Spain) Wear simulations and calculations included in the appendices Instructor presentations slides with book figures available from the companion site Critical Component Wear in Heavy Duty Engines is aimed at postgraduates in automotive engineering, engine design, tribology, combustion and practitioners involved in engine R&D for applications such as commercial vehicles, cars, stationary engines (for generators, pumps, etc.), boats and ships. This book is also a key reference for senior undergraduates looking to move onto advanced study in the above topics, consultants and product mangers in industry, as well as engineers involved in design of furnaces, gas turbines, and rocket combustion.

Download or read book Performance Deterioration Based on Existing historical Data written by G. P. Sallee and published by . This book was released on 1978 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the collection and analysis of historical data pertaining to the deterioration of JT9D engine performance are presented. The results of analyses of prerepair and postrepair engine test stand performance data from a number of airlines to establish the individual as well as average losses in engine performance with respect to service use are included. Analysis of the changes in mechanical condition of parts, obtained by inspection of used gas-path parts of varying age, allowed preliminary assessments of component performance deterioration levels and identification of the causitive factors. These component performance estimates, refined by data from special engine back-to-back testing related to module performance restoration, permitted the development of preliminary models of engine component/module performance deterioration with respect to usage. The preliminary assessment of the causes of module performance deterioration and the trends with usage are explained, along with the role each module plays in overall engine performance deterioration. Preliminary recommendations with respect to operating and maintenance practices which could be adopted to control the level of performance deterioration are presented. The needs for additional component sensitivity testing as well as outstanding issues are discussed.
