Download or read book On the Origins of Global History written by Sanjay Subrahmanyam and published by Collège de France. This book was released on 2016-03-17 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does one think of history on a world scale? Should one turn to the intellectuals of the past or the historians of the present? Universal history as it was practised from Antiquity started to change from the sixteenth century in varied contexts, from East Asia to Spanish America. Applying his extensive knowledge of archives across the world and his command of languages and historiographic traditions of Asia, Europe and the Americas, Sanjay Subrahmanyam considers the history of networks and exchanges of goods, myths and ideologies from a new perspective. He works outside traditional geopolitical frameworks based on the nation-state model, to present global history as a field defined and redefined by “connected histories”.

Download or read book Through Life Management written by Great Britain. National Audit Office and published by . This book was released on 2003 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developed under the Strategic Defence Review, and a key element in the Smart Acquisition reforms policy, the Through-Life Management approach to defence acquisition has been adopted by the Ministry of Defence in order to deliver a faster, and cheaper set of processes and systems for developing an efficient military capability. This report examines whether that capability has been delivered. Among a number of observations and recommendations, the NAO found that Through-Life had yet to become firmly established in the Department, and so yield its' benefits; that despite strong management support, no clear, consolidated strategy existed across the Department itself and that a plan had now been developed to push through the changes needed to implement the Through-Life Management approach more effectively in the Department.

Available in PDF, EPUB and Kindle. Book excerpt: The major objective of flight testing under extreme environmental conditions is to determine to what extent a weapon system, including essential support equipment and attendant crews can accomplish the design mission in the required climatic extremes, using technical Order procedures. Such testing has historically often revealed design deficiencies that impact the operational capabilities of the air vehicle involved. This volume in ... discusses the philosophy, purpose and methods for conducting ground and flight tests of weapon systems in extreme environmental conditions. The areas ... testing in a controlled artificial environment, as well as cold artic, hot desert, tropic, and adverse-weather conditions. Also included are the technical and safety aspects of planning, instrumentation and data acquisition requirements, types of tests conduct and reporting requirements.

Download or read book On Subscale Flight Testing written by Alejandro Sobron and published by Linköping University Electronic Press. This book was released on 2018-11-05 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence. Physical models are very effective at revealing issues that are sometimes not correctly identified in the virtual domain, and hence can be a valuable complement to other design tools. But traditional wind-tunnel testing cannot always meet all of the requirements of modern aeronautical research and development. It is nowadays too expensive to use these scarce facilities to explore different design iterations during the initial stages of aircraft development, or to experiment with new and immature technologies. Testing of free-flight subscale models, referred to as Subscale Flight Testing (SFT), could offer an affordable and low-risk alternative for complementing conventional techniques with both qualitative and quantitative information. The miniaturisation of mechatronic systems, the advances in rapid-prototyping techniques and power storage, as well as new manufacturing methods, currently enable the development of sophisticated test objects at scales that were impractical some decades ago. Moreover, the recent boom in the commercial drone industry has driven a quick development of specialised electronics and sensors, which offer nowadays surprising capabilities at competitive prices. These recent technological disruptions have significantly altered the cost-benefit function of SFT and it is necessary to re-evaluate its potential in the contemporary aircraft development context. This thesis aims to increase the comprehension and knowledge of the SFT method in order to define a practical framework for its use in aircraft design; focusing on low-cost, short-time solutions that don’t require more than a small organization and few resources. This objective is approached from a theoretical point of view by means of an analysis of the physical and practical limitations of the scaling laws; and from an empirical point of view by means of field experiments aimed at identifying practical needs for equipment, methods, and tools. A low-cost data acquisition system is developed and tested; a novel method for semi-automated flight testing in small airspaces is proposed; a set of tools for analysis and visualisation of flight data is presented; and it is also demonstrated that it is possible to explore and demonstrate new technology using SFT with a very limited amount of economic and human resources. All these, together with a theoretical review and contextualisation, contribute to increasing the comprehension and knowledge of the SFT method in general, and its potential applications in aircraft conceptual design in particular.

Available in PDF, EPUB and Kindle. Book excerpt: Simulations have been a fixture of aviation training for many years. Advances in simulator technology now enable modern flight simulation to mimic very closely the look and feel of real world flight operations. In spite of this, responsible researchers, trainers, and simulation developers should look beyond mere simulator fidelity to produce meaningful training outcomes. Optimal simulation training development can unquestionably benefit from knowledge and understanding of past, present, and future research in this topic area. As a result, this volume of key writings is invaluable as a reference, to help guide exploration of critical research in the field. By providing a mix of classic articles that stand the test of time, and recent writings that illuminate current issues, this volume informs a broad range of topics relevant to simulation training in aviation.

Download or read book Flight Test Instrumentation written by M. A. Perry and published by Elsevier. This book was released on 2016-11-04 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight Test Instrumentation is a collection of papers presented at the Third International Symposium on Flight Test Instrumentation held in 1964 under the auspices of the Department of Flight of the College of Aeronautics in Cranfield, UK. The symposium provided a forum for discussing advances in flight test instrumentation and covered topics ranging from pre-detection recording in the megacycle range to some problems and uses of fuel flow measurements in supersonic aircraft. This volume is comprised of 14 chapters and begins by describing angle of attack and angle of sideslip measurements using fully de-iced non-movable differential pressure-sensing heads and low-range capacitive pressure transducers. The next chapter explores errors in stability derivative measurements that can occur due to shortcomings in instrumentation design, as well as the implications of such errors for the development of a modern supersonic aeroplane. The application of the vector plotting technique to flight flutter testing of the Hawker Siddeley Trident is then considered. Subsequent chapters focus on the use of high-accuracy instrumentation techniques for non-steady flight measurements; strain gauging for transient heating cases; and free-flight model techniques for aerodynamic research at supersonic and hypersonic speeds. This book will be a useful resource for students, practitioners, and officials of aeronautics.
