Book excerpt: This study documents the design and analysis of four types of advanced technology commercial transport airplane configurations (small, medium large and very large) with an assumed technology readiness date of 2010. These airplane configurations were used as a platform to evaluate the design concept and installed performance of advanced technology engines being developed under the NASA Ultra Efficient Engine Technology (UEET) program. Upon installation of the UEET engines onto the UEET advanced technology airframes, the small and medium airplanes both achieved an additional 16% increase in fuel efficiency when using GE advanced turbofan engines. The large airplane achieved an 18% increase in fuel efficiency when using the P&W geared fan engine. The very large airplane (i.e. BWB), also using P&W geared fan engines, only achieved an additional 16% that was attributed to a non-optimized airplane/engine combination.Daggett, David L. and Geiselhart, Karl A.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Design structure matrix (DSM) is a straightforward and flexible modeling technique that can be used for designing, developing, and managing complex systems. DSM offers network modeling tools that represent the elements of a system and their interactions, thereby highlighting the system's architecture (or designed structure). Its advantages include compact format, visual nature, intuitive representation, powerful analytical capacity, and flexibility. Used primarily so far in the area of engineering management, DSM is increasingly being applied to complex issues in health care management, financial systems, public policy, natural sciences, and social systems. This book offers a clear and concise explanation of DSM methods for practitioners and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: The treatise supports understanding the phenomena of complexity in engineering, distinguishes complexity from other challenges and presents an overview of definitions and applied approaches.The historical background of complexity management is explained by highlighting the important epochs, their key actors and their discoveries, findings and developments. Knowing about the appearance of early system awareness in ancient Greece, the creation of mechanical philosophy in the 17th century and the discovery of classic physics enables the reader to better comprehend modern system sciences and management approaches.A classification of complexity management approaches by research fields indicates current focus areas and starting points for future discussions. In a comprehensive map, the classification points out mutual overlaps between engineering disciplines in terms of similar complexity management approaches.Finally, the treatise introduces a generic complexity management framework, which is based on structural management approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Aircraft as a System of Systems: A Business Process Perspective, written by Sean Barker, FBCS CEng and a former research scientist at BAE Systems in the UK, explains how developing even simple parts like a lever needs several different types of knowledge before moving on to the complications of designing a system. Today’s airframers have taken on more of the role of systems integrators, putting the focus on the aircraft as a system-of-many-systems. Whereas an aircraft integrates many different systems into a single design, the system of systems which supports it is built by federating the systems of the different organizations, which were built and run independently of each other. Aircraft as a System of Systems: A Business Process Perspective provides a thorough analysis of how building aircraft taps into a huge pool of knowledge, how its complexity is also reflected in the numerous process links that exchange knowledge between different groups. But unlike conventional business processes, design processes do not follow one step after another – rather, a decision made at one point in the design is communicated to other areas of the design, which may in turn feed back new constraints that force the first decision to be revised.

Available in PDF, EPUB and Kindle. Book excerpt: The propulsion system is arguably the most critical part of the aircraft; it certainly is the single most expensive component of the vehicle. Ensuring that engines operate reliably without major maintenance issues is an important goal for all operators, military or commercial. Engine health management (EHM) is a critical piece of this puzzle and has been a part of the engine maintenance for more than five decades. In fact, systematic condition monitoring was introduced for engines before it was applied to other systems on the aircraft. Diagnostics and Prognostics of Aerospace Engines is a collection of technical papers from the archives of SAE International, which introduces the reader to a brief history of EHM, presents some examples of EHM functions, and outlines important future trends. The goal of engine health maintenance is ultimately to reduce the cost of operations by catching problems before they become major issues, by helping reduce repair times through diagnostics, and by facilitating logistic optimization through prognostic estimates. Diagnostics and Prognostics of Aerospace Engines shows that the essence of these goals has not changed over time.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade or so, systems integration has become a key factor in the operations, strategy and competitive advantage of major corporations in a wide variety of sectors (e.g. computing, automotive, telecommunications, military systems and aerospace). Systems integration is a strategic task that pervades business management not only at the technical level but also at the management and strategic levels. This book shows how and why this new kind of systems integration has evolved into an emerging model of industrial organization whereby firms, and groups of firms, join together different types of knowledge, skill and activity, as well as hardware, software, and human resources to produce new products for the marketplace. This book is the first to systematically explore systems integration from a business and innovation perspective. Contributors delve deeply into the nature, dimensions and dynamics of the new systems integration, deploying research and analytical techniques from a wide variety of disciplines including, the theory of the firm, the history of technology, industrial organization, regional studies, strategic management, and innovation studies. This wealth of research capability provides deep insights into the new model of systems integration and supports this with an abundance of empirical evidence. The book is organized in three main parts. The first part focuses on the history of systems integration. Contributors trace the early history of systems integration using different industrial examples. The second part presents theoretical and analytical aspects of systems integration. Contributions concentrate on the regulatory and cognitive features of systems integration, the relationships between systems integration and regional competitive advantage, and the way in which systems integration supports the competitive advantage of firms. The third part takes industry and firm-level approaches. Contributions focus on different sectors and highlight the specificity of systems integration in various industrial domains, stressing its importance for systems integration in the case of complex capital goods, such as aircraft and telecommunications equipment, as well as consumer goods, such as personal computers and automobiles.
