Aerodynamic design of aircraft presented with realistic applications, using CFD software. Tutorials, exercises, and mini-projects provided involve design of real aircraft. Using online resources and supplements, this text prepares last-year undergraduates and first-year graduate students for industrial aerospace design and analysis tasks.
Aircraft affect global climate through emissions of greenhouse gases and their precursors and by altering cirrus cloudiness. Changes in operations and design of future aircraft may be necessary to meet goals for limiting climate change. One method for reducing climate impacts involves designing aircraft to fly at altitudes where the impacts of NOx emissions are less severe and persistent contrail formation is less likely. By considering these altitude effects and additionally applying climate mitigation technologies, impacts can be reduced by 45-70% with simultaneous savings in total operating costs. Uncertainty is assessed, demonstrating that relative climate impact savings can be expected despite large scientific uncertainties. Strategies for improving climate performance of existing aircraft are also explored, revealing potential climate impact savings of 20-40%, traded for a 2% increase in total operating costs and reduced maximum range.
The theory of concurrent engineering is based on the concept that the different phases of a product lifecycle should be conducted concurrently and initiated as early as possible within the product creation process. Concurrent engineering is important in many industries, including automotive, aerospace, shipbuilding, consumer goods and environmental engineering, as well as in the development of new services and service support. This book presents the proceedings of the 21st ISPE Inc. International Conference on Concurrent Engineering, held at Beijing Jiaotong University, China, in September 2014. It is the first volume of a new book series: 'Advances in Transdisciplinary Engineering'. The tit...
This book provides research results using computational methods for fluid dynamics and engineering problems in aeronautics and other scientific and industrial applications. It gives an overview on the state of the art and the technology trends requiring advanced computational methods towards digitization in industrial and scientific processes. The chapters are based on Special Technology Sessions of the WCCM-ECCOMAS Virtual Congress 2021.
Concurrent Engineering (CE) is based on the premise that different phases of a product’s lifecycle should be conducted concurrently and initiated as early as possible within the Product Creation Process (PCP). It has become the substantive basic methodology in many industries, including automotive, aerospace, machinery, shipbuilding, consumer goods, process industry and environmental engineering. CE aims to increase the efficiency of the PCP and reduce errors in later phases while incorporating considerations for full lifecycle and through-life operations. This book presents the proceedings of the 22nd ISPE Inc. (International Society for Productivity Enhancement) International Conference ...
Computing in the Nordic countries started in late 1940s mainly as an engineering activity to build computing devices to perform mathematical calculations and assist mathematicians and engineers in scientific problem solving. The early computers of the Nordic countries emerged during the 1950s and had names like BARK, BESK, DASK, SMIL, SARA, ESKO, and NUSSE. Each of them became a nucleus in institutes and centres for mathematical computations programmed and used by highly qualified professionals. However, one should not forget the punched-card machine technology at this time that had existed for several decades. In addition, we have a Nordic name, namely Frederik Rosing Bull, contributing to ...
As a concept, Concurrent Engineering (CE) initiates processes with the goal of improving product quality, production efficiency and overall customer satisfaction. Services are becoming increasingly important to the economy, with more than 60% of the GDP in Japan, the USA, Germany and Russia deriving from service-based activities. The definition of a product has evolved from the manufacturing and supplying of goods only, to providing goods with added value, to eventually promoting a complete service business solution, with support from introduction into service and from operations to decommissioning. This book presents the proceedings of the 20th ISPE International Conference on Concurrent Engineering, held in Melbourne, Australia, in September 2013. The conference had as its theme Product and Service Engineering in a Dynamic World, and the papers explore research results, new concepts and insights covering a number of topics, including service engineering, cloud computing and digital manufacturing, knowledge-based engineering and sustainability in concurrent engineering.
ALASKA SHIPWRECKS 1750-2015 is an encyclopedic accounting of all shipwrecks and losses of life in the Alaska Marine environment. Compiled and written by Captain Warren Good with research assistance and extensive consultation provided by maritime historian Michael Burwell this book is filled with a wealth of information for those interested in Alaska maritime history and the multitude of associated tragedies. Included are details of all known wrecks including vessel information, crew member and passenger names, locations, first hand descriptions of events and sources of all information. In addition, comprehensive comments by Captain Warren Good further elaborate on the location and disposition of many of the disasters.
Die »Mädchenarbeit« ist in den vergangenen Jahren in die Defensive geraten. Gesellschaftliche Veränderungen wie Gender Mainstreaming oder die Diskussion um ›arme Jungs‹ setzen die geschlechterreflektierende Arbeit mit Mädchen unter Legitimationsdruck. Auch wissenschaftliche Diskurse um Dekonstruktion und Intersektionalität stellen die Frage, an wen sich Mädchenarbeit heute richten kann. Im Themenraum von Gender, Klasse, Migration und Ethnizität reflektieren die Autorinnen und Autoren dieses Sammelbandes ihre langjährige Berufspraxis in der Mädchenarbeit und machen deutlich: Mädchenarbeit ist heute wichtiger denn je.
