Download or read book A Superconducting Magnet Dewar Missile for Launching in Ballistic Ranges written by E. E. Erickson and published by . This book was released on 1976 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: One concept for magnetic guidance of projectiles in hypervelocity ballistic ranges is the use of a superconducting magnet within the projectile. The magnet must survive the large launch loads (250,000 g's) necessary to achieve test velocities (20,000 ft/sec). This report describes a conceptual design of a dewar which contains a superconducting magnet and its performance limitations. Thermal holding time for the preposed dewar would be in excess of 90 min. Structural strength aspects of the dewar components limit the launch load to 15,000 g's. consequently the current launcher at AEDC (50 ft long) would be limited to velocities of about 5,000 ft/sec or alternatively, an 830-ft-long launcher would be required to produce the desired velocity (20,000 ft/sec). The use of new launch techniques or magnet configurations could affect these results. (Author).

Download or read book A Magnetic guideway guided projectile System Concept for Aeroballistic Ranges written by George D Arney (Jr.) and published by . This book was released on 1977 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A system concept for the incorporation of magnetic projectile guidance into aeroballistic ranges is presented and analyzed. Basis of the concept is motion-induced, electrodynamic interaction between conductive material in the projectile's forebody and a guideway of field source currents. Theory is developed for deployment of the currents such that on the one hand the forebody will be repulsed toward the guideway centerline as a function of error in lateral position whereas, on the other hand, there will be damping of resulting lateral motion. Expressions are subsequently derived which interrelate the magnitude of forces to the magnitude of guideway currents, and generalized equations of motion for the projectile are developed with both electrodynamic and aerodynamic forces being considered. A design example is included wherein the developed theory is correlated to an existing aeroballistic range (AEDC/VKF Range G) where projectiles with base diameters on the order of 0.05 m are launched at velocities of 4,000 to 6,000 m/sec. Results are gratifying in that computed flight paths for varying conditions indicate that stable guided flight can be achieved with guideway currents of reasonable magnitude. Practical means of providing these are discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers, for the first time, an overview of nearly all of the magnetic sensors that exist today. The book is offering the readers a thorough and comprehensive knowledge from basics to state-of-the-art and is therefore suitable for both beginners and experts. From the more common and popular AMR magnetometers and up to the recently developed NV center magnetometers, each chapter is describing a specific type of sensor and providing all the information that is necessary to understand the magnetometer behavior including theoretical background, noise model, materials, electronics, design and fabrication techniques, etc.

Download or read book Cryogenic Process Engineering written by Klaus D. Timmerhaus and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryogenics, a term commonly used to refer to very low temperatures, had its beginning in the latter half of the last century when man learned, for the first time, how to cool objects to a temperature lower than had ever existed na tu rally on the face of the earth. The air we breathe was first liquefied in 1883 by a Polish scientist named Olszewski. Ten years later he and a British scientist, Sir James Dewar, liquefied hydrogen. Helium, the last of the so-caBed permanent gases, was finally liquefied by the Dutch physicist Kamerlingh Onnes in 1908. Thus, by the beginning of the twentieth century the door had been opened to astrange new world of experimentation in which aB substances, except liquid helium, are solids and where the absolute temperature is only a few microdegrees away. However, the point on the temperature scale at which refrigeration in the ordinary sense of the term ends and cryogenics begins has ne ver been weB defined. Most workers in the field have chosen to restrict cryogenics to a tem perature range below -150°C (123 K). This is a reasonable dividing line since the normal boiling points of the more permanent gases, such as helium, hydrogen, neon, nitrogen, oxygen, and air, lie below this temperature, while the more common refrigerants have boiling points that are above this temperature. Cryogenic engineering is concerned with the design and development of low-temperature systems and components.

Available in PDF, EPUB and Kindle. Book excerpt: 1970 marked the seventh return of the Cryogenic Engineering Conference, now affiliated with the National Academy of Sciences through the Division of Engineering, National Research Council, to Boulder, Colorado. Local arrangements for this year's meeting have again been capably handled by the University of Colorado and the Cryogenics Division, NBS Institute for Basic Standards. The Cryogenic Engineering Conference Committee gratefully acknowledges the assistance of these two organizations, and particularly the Bureau of Continuation Education of the University of Colorado, for serving as hosts to the 1970 Cryogenic Engineering Conference. The National Academy of Sciences is a private, honorary organization of more than 700 scientists and engineers elected on the basis of outstanding con tributions to knowledge. Established by a Congressional Act of Incorporation signed by Abraham Lincoln on March 3, 1863, and supported by private and public funds, the Academy works to further science and its use for the general welfare by bringing together the most qualified individuals to deal with scientific and tech nological problems of broad significance. Under the terms of its Congressional charter, the Academy is also called upon to act as an official-yet independent adviser to the Federal Government in any matter of science and technology. This provision accounts for the close ties that have always existed between the Academy and the Government, although the Academy is not a governmental agency and its activities are not limited to those on behalf of the Government.
