Download or read book Dynamics of Meteor Outbursts and Satellite Mitigation Strategies written by Glenn E. Peterson and published by AIAA. This book was released on 1999 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential threat posed by Leonid meteroids to orbiting spacecraft over the next several years calls for new dynamic mitigation strategies to assist the satellite community in reducing the danger to its vehicles. This book offers deliberate dynamic mitigation strategies to complement the traditional shielding strategies, providing mission operators additional ways to decrease the danger. Five different attitude control and orbit maneuvering options are examined in detail. The information is presented in algorithmic form to allow technically competent, but meteoroid inexperienced, operators to easily understand the phenomena, assess the danger, and implement procedures. Although general in scope, the book emphasizes the Leonid meteor events of the 1998-2002 timeframe.

Download or read book Influence of Some Interstitial Materials on the Thermal Contact Conductance written by Jin-Tyan Lin and published by . This book was released on 1970 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Experiments have been conducted to investigate the effect of the interstitial materials at the interface of metals in contact. The test specimens were cylinders, axially aligned and loaded. Specimen materials were 606l-T6 aluminum alloy, and the contact fillers were stainless steel wire screens, aluminum foil, paper, and dielectric greases. The tests were conducted at atmospheric environment. The contact pressure ranged from 25 psi to 600 psi. The mean interface temperature ranged from 100 °F to 200 °F. Surface roughnesses of specimens were from 25 to 35 micro-inches, rms. The results of the investigation reveal that if the contact surfaces are sandwiched with interstitial material, the interface conductance is primarily dependent upon the thermal conductivity of this interstitial material. Some materials such as wire screen have the advantage of being less dependent upon temperature, pressure, and contact surface conditions, compared to bare junctions. The interstitial materials can either increase or decrease the contact resistance. In the case of aluminum foil sandwiched between the aluminum surfaces, the interface conductance increases three times, and sandwiched with greases, increases 10 times as much as that of the aluminum bare junction. On the other hand, if sandwiched with paper the interface conductance is lowered to 70 percent. This paper presents various characteristics of interstitial materials and provides some reliable data for engineering design purposes and further analysis in this field"--Abstract, leaf ii.

Download or read book A Transient Method of Negligible Internal Thermal Resistance for Determining Thermal Contact Conductance in a Vacuum written by Richard Chuka Oboka and published by . This book was released on 1970 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A transient method for experimentally determining the interface conductance between metallic surfaces in contact is developed. The method applies the theory of negligible internal thermal resistance of one of the materials which form the interface. The method is applicable when the interface conductance is very low, a situation which exists when low conductance interstitial materials are used between contacting surfaces for purposes of thermal isolation. In this investigation, stainless steel wire screens of 10 and 100 mesh were used as interstitial materials between aluminum surfaces in a vacuum environment of 10−5 to 10−6 Torr. The interface pressure ranged from 40 to 200 psi. The roughness of the contacting surfaces ranged from 15 to 25 micro inches, root mean square. The experimental results show that the average thermal conductance obtained by the transient method was from 96.04 to 98.5 % of the steady state thermal conductance when the 10 mesh wire screen was used as the interstitial material and was from 79.28 to 91.13 % of the steady state thermal conductance when the 100 mesh wire screen was used. The results thus show that the method of negligible internal thermal resistance is quite reliable for very low interface conductances"--Abstract, leaf ii.

Available in PDF, EPUB and Kindle. Book excerpt: Electronic technology is developing rapidly and, with it, the problems associated with the cooling of microelectronic equipment are becoming increasingly complex. So much so that it is necessary for experts in the fluid and thermal sciences to become involved with the cooling problem. Such thoughts as these led to an approach to leading specialists with a request to contribute to the present book. Cooling of Electronic Systems presents the technical progress achieved in the fundamentals of the thermal management of electronic systems and thermal strategies for the design of microelectronic equipment. The book starts with an introduction to the cooling of electronic systems, involving such topics as trends in computer system cooling, the cooling of high performance computers, thermal design of microelectronic components, natural and forced convection cooling, cooling by impinging air and liquid jets, thermal control systems for high speed computers, together with a detailed review of advances in manufacturing and assembly technology. Following this, practical methods for the determination of the parameters required for the thermal analysis of electronic systems and the accurate prediction of temperature in consumer electronics. Cooling of Electronic Systems is currently the most up-to-date book on the thermal management of electronic and microelectronic equipment, and the subject is presented by eminent scientists and experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Thermophysics: Applications to Thermal Design of Spacecraft is a collection of technical papers presented at the American Institute of Aeronautics and Astronautics's 7th Aerospace Sciences Meeting, held on January 20-22, 1969, in New York and 4th Thermophysics Conference, held on June 16-18, 1969, in San Francisco, California. Contributors explore the applications of thermophysics to thermal design of spacecraft and tackle topics ranging from conduction and radiation to convection, phase change, and thermal design techniques. Comprised of 26 chapters, this volume begins with a discussion on experimental thermophysical properties, focusing on topics such as contact thermal resistance theory and experiment; optics and engineering in thermophysics; and crystal growth during melting and freezing and its application to phase change in thermal control. The physical parameters affecting radiation property degradation under simulated space environmental conditions are also considered. Radiative analysis is treated in the next section, with emphasis on surface effects upon radiative properties; two-component heat pipes; parametric thermal control requirements for future manned spacecraft; and thermal considerations of a landed vehicle on the surface of Mars. This book should be of interest to practitioners in astronautics and aeronautics.
