Download or read book Extreme Events in Geospace written by Natalia Buzulukova and published by Elsevier. This book was released on 2017-12-01 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight.

Download or read book Advanced Dynamics of Rolling Elements written by P.K. Gupta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any rotating machinery system, the bearing has traditionally been a crit ical member of the entire system, since it is the component that permits the relative motion between the stationary and moving parts. Depending on the application, a number of different bearing types have been used, such as oil-lubricated hydrodynamic bearings, gas bearings, magnetic suspensions, rolling element bearings, etc. Hydrodynamic bearings can provide any desired load support, but they are limited in stiffness and the associated power loss may be quite large. Gas bearings are used for high-precision applications where the supported loads are relatively light, bearing power losses are very low, and the rotating speeds generally high. For super precision components where no frictional dissipation or bearing power loss can be tolerated, magnetic suspensions are employed; again, the load support requirements are very low. Rolling element bearings have been widely used for those applications that require greater bearing versatility, due to the requirements for high-load and high-stiffness characteristics, while allowing moderate power loss and permitting variable speeds. A study of the dynamic interaction of rolling elements is, therefore, the subject of this text. Texts covering the analysis and design methodology of rolling elements are very limited. Notable works include Analysis of Stresses and Deflections (Jones, 1946, Vols. I and II), Ball and Roller Bearings, Their Theory, Design and Application (Eschmann, Hasbargen, and Weigand, 1958), Ball and Roller Bearing Engineering (Palmgren, 1959, 3rd ed. ), Advanced Bearing Technology (Bisson and Anderson, 1965), and Rolling Bearing Analysis (Harris, 1966).

Download or read book Inside the Space Ships written by George Adamski and published by Pickle Partners Publishing. This book was released on 2018-03-12 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: What has happened to George Adamski since he wrote the famous incidents in Flying Saucers Have Landed? Since the memorable November 20, 1952, when he first made personal contact with a man from another world? Since December 13, 1952 when he was able to make photographs within 100 feet of the same saucer that had brought his original visitor? Inside The Space Ships is Adamski’s own story of what has happened to him since then. It begins with his first meeting, a few months later, with a second man from another world—his first meeting with one who speaks to him. This second visitor brings him to a Venusian Scout (flying saucer) and this, in turn, brings him to a mother ship. Later lie is conveyed in both a Saturnian Scout and a Saturnian mother ship. Adamski tells us what transpires in these space craft and what the men and women from other worlds have told him. Adamski’s photographs of flying saucers, originally published in Flying Saucers Have Landed, have since become world-famous as other witnesses in other parts of the world have succeeded in taking photographs identical with his. Now, however, in Inside The Space Ships, Adamski gives us 16 photographs and illustrations, no longer of Scouts (flying saucers) mostly, but of the great space ships from which they are launched. The main group of these photographs was taken in April, 1955, and neither the photographs nor a description of them has ever been published before.

Download or read book Helicopter Flight Dynamics written by Gareth D. Padfield and published by John Wiley & Sons. This book was released on 2018-09-07 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.
Download or read book Skycrane written by John A. McKenna and published by Library of Flight. This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Skycrane was the last creation of aircraft design pioneer Igor Sikorsky. In SKYCRANE: Igor Sikorsky's Last Vision, former Sikorsky Aircraft Executive Vice President John A. McKenna traces the development of this remarkable helicopter from original concept and early sketches to standout performer for the military and private industry. Responsible for building the first S-64 Skycrane in 1961 and for supporting its Army and commercial programs, McKenna has written a comprehensive history chronicling a radically designed helicopter that many thought would not succeed. Indeed, initial versions generated no orders. But General Harry Kinnards vision and advocacy resulted in the Skycranes support of combat operations in Vietnam as part of the groundbreaking concept of supporting Army troops with helicopters rather than trucks. In 1971 Erickson Lumber Company acquired the first Skycrane intended for commercial use to move timber deep in American forests. Owner Jack Erickson later acquired the world manufacturing and support rights to the aircraft creating Erickson Air-Crane Inc. A half century after its first flight the Skycrane continues to save lives, provide essential services, and earn daily profits worldwide. Beautifully illustrated with scores of historical photographs, SKYCRANE features interviews with engineers who designed and tested the helicopter and with Army pilots who flew it during combat in Vietnam. This engagingly written work is the definitive history of a unique and important aircraft.

Download or read book Reinventing the Propeller written by Jeremy R. Kinney and published by Cambridge University Press. This book was released on 2017-03-24 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: An international community of specialists reinvented the propeller during the Aeronautical Revolution, a vibrant period of innovation in North America and Europe from World War I to the end of World War II. They experienced both success and failure as they created competing designs that enabled increasingly sophisticated and 'modern' commercial and military aircraft to climb quicker and cruise faster using less power. Reinventing the Propeller nimbly moves from the minds of these inventors to their drawing boards, workshops, research and development facilities, and factories, and then shows us how their work performed in the air, both commercially and militarily. Reinventing the Propeller documents this story of a forgotten technology to reveal new perspectives on engineering, research and development, design, and the multi-layered social, cultural, financial, commercial, industrial, and military infrastructure of aviation.
