Available in PDF, EPUB and Kindle. Book excerpt: The patent concerns a formulation providing coatings having high solar absorptance to infrared emittance ratios comprises oxidized copper flakes, a polymeric binder and a solvent for the binder. The oxidized copper flakes may be prepared by heating in an oxygen containing atmosphere prior to the inclusion in the coating formulation. The formulation is particularly useful for coating surfaces of missile and spacecraft structures where thermal balance is of prime importance. In general, the coated surfaces have a solar absorptance to infrared emittance ratio ranging from 1.80 to 2.60.

Download or read book Thermal Control Coatings an Analytical Treatment written by Max A. Turner and published by . This book was released on 1970 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The need for various types of thermal control coatings has been derived and summarized from an analysis of selected thermal problems frequently encountered in spacecraft hardware coupled with an analysis of variance in the parameters of the thermal balance. This overall analysis indicates the need for a complete series of stable coatings each having a minimum (0.1 or lower) solar absorptance but with different or controllable values of infrared emittance ranging from 0.3 to 1.0 in order to cover the entire range of desirable solar absorptance/emittance ratios from 0.1 to 0.3. This analysis was applied only to a generalized earth orbiting spacecraft. Where internal heat dissipation rates exceeded several watts/sq. ft., active heat removal systems would be required.

Available in PDF, EPUB and Kindle. Book excerpt: Solar Energy in Developing Countries is a documentation report with bibliography on solar energy research and development in developing countries such as those in Asia, Central and South America, Africa, and Middle East. Institutions in developed countries with solar activities of interest to developing countries are included. This volume consists of seven chapters and opens with an overview of the study followed by a discussion on solar activities of relevance to developing countries, focusing on the work of international or supranational organizations such as the United Nations, NATO, and the European Economic Community. The following chapters deal with the state of the art of solar energy applications as well as solar R&D work in developing countries, including solar distillation, solar cooking and drying, and solar refrigeration and air conditioning. Information and addresses on sources of literature, hardware and equipment are also provided, along with a detailed and comprehensive bibliography (mostly with abstracts). This book is intended for solar scientists and engineers, government officials, and others who are interested in solar R&D work in developing countries.

Download or read book Materials and Processes written by Barrie D. Dunn and published by Springer. This book was released on 2015-12-29 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to assist scientists and engineers select the ideal material or manufacturing process for particular applications; these could cover a wide range of fields, from light-weight structures to electronic hardware. The book will help in problem solving as it also presents more than 100 case studies and failure investigations from the space sector that can, by analogy, be applied to other industries. Difficult-to-find material data is included for reference. The sciences of metallic (primarily) and organic materials presented throughout the book demonstrate how they can be applied as an integral part of spacecraft product assurance schemes, which involve quality, material and processes evaluations, and the selection of mechanical and component parts. In this successor edition, which has been revised and updated, engineering problems associated with critical spacecraft hardware and the space environment are highlighted by over 500 illustrations including micrographs and fractographs. Space hardware captured by astronauts and returned to Earth from long durations in space are examined. Information detailed in the Handbook is applicable to general terrestrial applications including consumer electronics as well as high reliability systems associated with aeronautics, medical equipment and ground transportation. This Handbook is also directed to those involved in maximizing the relia bility of new materials and processes for space technology and space engineering. It will be invaluable to engineers concerned with the construction of advanced structures or mechanical and electronic sub-systems.

Download or read book Development of Improved Thermal Control Coatings for Space Assets written by and published by . This book was released on 2004 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal control coatings play a critical role in the thermal management of space assets through reflection of incident solar energy and emittance of infrared heat. An investigation into the potential minimization of required film thickness through optimization of zinc oxide pigment particle size was performed. The utilization of a 1.5-micron average particle size pigment in the coating formulation resulted in a slightly improved solar absorbance/emittance value of 0.132 in comparison with the currently used 5.0 micron average particle size pigment. Furthermore, this improved value was obtained at a dry film thickness 18% thinner (4.9 mils) than the current state of the art, which translates to weight savings without a sacrifice in thermal management properties. Use of the smaller particle size pigment also resulted in an improvement in the measured emittance (0.94), likely due to a more uniform surface roughness and fewer large pores present in the film.
