Kossman and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2004 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper covers the construction and testing of a proof-of-concept model of a high altitude, rigid-winged, tethered aircraft. The aircraft is designed as a replacement for aerostats, to act as a payload positioning platform for communication and surveillance equipment. The initial design was found to be unstable through testing, and a series of 60 cm wingspan, small-scale models were constructed to experimentally modify the design into a stable aircraft. Once a suitable design was obtained, a 1.2 m scale model was constructed with a horizon sensing, closed-loop proportional feedback control system for lateral stability augmentation. The stability-augmented model flew stably, for extended periods. Lift and drag measurements were obtained from the flight tests and compared to theoretical calculations. A wind tunnel test was also conducted on the small-scale model to verify the flight test results. Finally, improvements to the stability control system design were suggested, and recommendations were made for larger-scale model construction.

Download or read book Airborne Wind Energy written by Roland Schmehl and published by Springer. This book was released on 2018-03-31 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in-depth coverage of the latest research and development activities concerning innovative wind energy technologies intended to replace fossil fuels on an economical basis. A characteristic feature of the various conversion concepts discussed is the use of tethered flying devices to substantially reduce the material consumption per installed unit and to access wind energy at higher altitudes, where the wind is more consistent. The introductory chapter describes the emergence and economic dimension of airborne wind energy. Focusing on “Fundamentals, Modeling & Simulation”, Part I includes six contributions that describe quasi-steady as well as dynamic models and simulations of airborne wind energy systems or individual components. Shifting the spotlight to “Control, Optimization & Flight State Measurement”, Part II combines one chapter on measurement techniques with five chapters on control of kite and ground stations, and two chapters on optimization. Part III on “Concept Design & Analysis” includes three chapters that present and analyze novel harvesting concepts as well as two chapters on system component design. Part IV, which centers on “Implemented Concepts”, presents five chapters on established system concepts and one chapter about a subsystem for automatic launching and landing of kites. In closing, Part V focuses with four chapters on “Technology Deployment” related to market and financing strategies, as well as on regulation and the environment. The book builds on the success of the first volume “Airborne Wind Energy” (Springer, 2013), and offers a self-contained reference guide for researchers, scientists, professionals and students. The respective chapters were contributed by a broad variety of authors: academics, practicing engineers and inventors, all of whom are experts in their respective fields.

Download or read book The Paths of Heaven The Evolution of Airpower Theory written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airpower is not widely understood. Even though it has come to play an increasingly important role in both peace and war, the basic concepts that define and govern airpower remain obscure to many people, even to professional military officers. This fact is largely due to fundamental differences of opinion as to whether or not the aircraft has altered the strategies of war or merely its tactics. If the former, then one can see airpower as a revolutionary leap along the continuum of war; but if the latter, then airpower is simply another weapon that joins the arsenal along with the rifle, machine gun, tank, submarine, and radio. This book implicitly assumes that airpower has brought about a revolution in war. It has altered virtually all aspects of war: how it is fought, by whom, against whom, and with what weapons. Flowing from those factors have been changes in training, organization, administration, command and control, and doctrine. War has been fundamentally transformed by the advent of the airplane.

Download or read book The Birth of NASA written by Manfred "Dutch" von Ehrenfried and published by Springer. This book was released on 2016-03-23 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of the work of the original NASA space pioneers; men and women who were suddenly organized in 1958 from the then National Advisory Committee on Aeronautics (NACA) into the Space Task Group. A relatively small group, they developed the initial mission concept plans and procedures for the U. S. space program. Then they boldly built hardware and facilities to accomplish those missions. The group existed only three years before they were transferred to the Manned Spacecraft Center in Houston, Texas, in 1962, but their organization left a large mark on what would follow.Von Ehrenfried's personal experience with the STG at Langley uniquely positions him to describe the way the group was structured and how it reacted to the new demands of a post-Sputnik era. He artfully analyzes how the growing space program was managed and what techniques enabled it to develop so quickly from an operations perspective. The result is a fascinating window into history, amply backed up by first person documentation and interviews.

Available in PDF, EPUB and Kindle. Book excerpt: The volume offers a comprehensive introduction to the archaeology of the southern Levant (modern day Israel, Palestine and Jordan) from the Paleolithic period to the Islamic era, presenting the past with chronological changes from hunter-gatherers to empires. Written by an international team of scholars in the fields of archaeology, epigraphy, and bioanthropology, the volume presents central debates around a range of archaeological issues, including gender, ritual, the creation of alphabets and early writing, biblical periods, archaeometallurgy, looting, and maritime trade. Collectively, the essays also engage diverse theoretical approaches to demonstrate the multi-vocal nature of studying the past. Significantly, The Social Archaeology of the Levant updates and contextualizes major shifts in archaeological interpretation.
