Multi-Disciplinary Development of a Smart CMC Combustor for an Intelligent Engine System


Book Description

The findings are described of an investigation to determine the feasibility of utilizing temperature and/or strain and stress sensor data in a computer program to monitor the health, in real time, of a ceramic gas turbine combustor operating at elevated temperatures (greater than 20,000 F). The ultimate purpose is to provide feedback to initiate corrective action should a threat to combustor health occur. This investigation evaluates the feasibility of the following: (1) Selection of sensor technology and CMC material for potential use in developing a smart CMC combustor, (2) development of a finite element simulation model of a sensor equipped, smart, CMC combustor based on and verified with test data, (3) use of simulation model and GENOA, NESSUS and CEMCAN available computer codes, to calibrate, and perform: (1) finite element analysis to predict CMC combustor structural response under load, (2) probabilistic analysis of the CMC combustor operating with benefit of sensor input, (3) probabilistic determination of sensor influence coefficients needed to enhance existing CEMCAN code capability for prediction of the structural response of a CMC combustor with embedded sensors, (4) modification of existing CMC data bank using CEMCAN to account for material property changes due to embedded sensors, and (5) use of GENOA to assist in design of a ceramic combustor for a gas turbine engine. Results obtained establish the feasibility of every item enumerated above.










Critical Materials Strategy


Book Description

This report examines the role of rare earth metals and other materials in the clean energy economy. It was prepared by the U.S. Department of Energy (DoE) based on data collected and research performed during 2010. In the report, DoE describes plans to: (1) develop its first integrated research agenda addressing critical materials, building on three technical workshops convened by the DoE during November and December 2010; (2) strengthen its capacity for information-gathering on this topic; and (3) work closely with international partners, including Japan and Europe, to reduce vulnerability to supply disruptions and address critical material needs. Charts and tables. This is a print on demand report.




The Mechatronics Handbook - 2 Volume Set


Book Description

The first comprehensive reference on mechatronics, The Mechatronics Handbook was quickly embraced as the gold standard in the field. From washing machines, to coffeemakers, to cell phones, to the ubiquitous PC in almost every household, what, these days, doesn’t take advantage of mechatronics in its design and function? In the scant five years since the initial publication of the handbook, the latest generation of smart products has made this even more obvious. Too much material to cover in a single volume Originally a single-volume reference, the handbook has grown along with the field. The need for easy access to new material on rapid changes in technology, especially in computers and software, has made the single volume format unwieldy. The second edition is offered as two easily digestible books, making the material not only more accessible, but also more focused. Completely revised and updated, Robert Bishop’s seminal work is still the most exhaustive, state-of-the-art treatment of the field available.

The Urban Rail Development Handbook


Book Description

Cities across the globe are looking to develop affordable, environmentally friendly, and socially responsible transportation solutions that can meet the accessibility needs of expanding metropolitan populations and support future economic and urban development. When appropriately planned and properly implemented as part of a larger public transportation network, urban rail systems can provide rapid mobility and vital access to city centers from surrounding districts. High-performing urban rail services, when carefully approached as development projects, can help enhance quality of life by giving citizens access to employment opportunities, essential services, urban amenities, and neighboring communities. The purpose of this Handbook is to synthesize and disseminate knowledge to inform the planning, implementation, and operations of urban rail projects with a view towards: -- Emphasizing the need for early studies and project planning; -- Making projects more sustainable (economically, socially, and environmentally); -- Improving socioeconomic returns and access to opportunities for users; -- Maximizing the value of private participation, where appropriate; and -- Building capacity within project implementing and managing institutions This Handbook provides experiential advice to tackle the technical, institutional, and financial challenges faced by decision makers considering urban rail projects. It brings together the expertise of World Bank staff and the input of numerous specialists to synthesize international 'good practices' and recommendations that are independent of commercial, financial political, or other interests. The material presented is intended as an honest-broker guide to maximize the impact and manage the challenges of urban rail systems in cities in both developed and developing countries. Rather than identify a single approach, this Handbook acknowledges the complexities and context necessary when approaching an urban rail development by helping to prepare decision makers to ask the right questions, consider the key issues, perform the necessary studies, apply adequate tools, and learn from international good practice all at the right time in the project development process.
