Available in PDF, EPUB and Kindle. Book excerpt: Heat transfer analyses of circular plan extended surfaces of space radiators with meteorite protection are presented herein. The circular extended surfaces include rectangular plates of uniform thickness and triangular, trapezoidal, and constant-temperature-gradient profiles. Complete radiator systems are analyzed and illustrative examples are given. The thermal analyses of circular extended surfaces produced relationships between the physical properties and dimensions, element and environmental temperatures, and rates of heat transfer. These are shown graphically for all types of elements. The optimum proportions of space radiator elements having the greatest ratio of heat radiation rate per pound of weight are also indicated graphically, and procedures for their calculation are shown. The discussions on radiators include dimensional-thermal relationships, and the temperature distribution in duct walls for complete units. Equations and graphs using simplifying assumptions are also presented for use in making a quick analysis of heat exchanger performance. Even though approximate, these data will save a designer considerable time in establishing a suitable configuration. General transient systems are also analyzed, as are more complex transient systems wherein a radiator is used for heat exchange to an environment.

This book was released on 1964 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical study of a flat condenser-radiator with a double fin-tube geometry (closed sandwich) with variable tube side-wall thickness was performed for a Rankine space-power electric-generating system. The analysis of the double fin radiator included consideration of tube and header pressure drops, meteoroid protection for the tubes and headers, along with a detailed presentation of the heat rejection analysis and total weight characteristics. The double fin-tube radiator is compared to a conventional central fin-tube configuration on a heat rejection to weight basis for a four-panel radiator configuration. Both fin and tube geometries are compared on the basis of the same power level, working fluid temperature, tube and header pressure drop, radiator material, and meteoroid protection criteria. A beryllium radiator for a 1-megawatt system and a columbium alloy radiator for a 5OO-kilowatt system, both at a radiating temperature of 1700 R, were chosen for the weight and geometry comparison. The conclusion reached indicates a substantial weight savings can be realized with the double fin-tube arrangement if the tube side-wall thickness can be reduced as a result of a possible meteoroid bumper effect of the enclosing fins. Weight reductions compared to the central fin-tube geometry of up to 32 to 39 percent were shown to be possible for the maximum reduction in side- wall thickness in the two examples considered. This result further substantiated the preliminary conclusions given in an earlier reference that compared the double and central fin-tube configurations neglecting the effects of headers, pressure drops, tube wall temperature drop, and powerplant thermodynamic cycle considerations.

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.
