THERMAL ANALYSIS AND METEOROID PROTECTION OF SPACE RADIATORS,
Abstract
This report presents a summary of the analysis used in the preliminary design of space radiators, based upon a one-dimensional, steady-state analysis of a plane rectangular, finned-tube configuration. The report covers the concepts of equivalent heat sink temperature (equilibrium temperature of a dry radiator), radiator thermal energy balance and area equations, fin effectiveness, finned-tube radiant energy interchange, armor-type meteoroid protection, fluid pressure drop, and radiator core weight. The analysis assumes that axial heat conduction may be neglected, the tube wall temperature is uniform in the radial and circumferential directions, the equivalent heat sink temperature is uniform over the surface of the radiator, the flow distribution to the tubes is uniform, and steady-state conditions prevail. Based upon this analysis, a digital computer program was developed. The program was designed primarily for the purpose of conducting preliminary design evaluations, obtaining design data, and conducting parametric analyses to determine the effects of the various radiator parameters such as finned-tube geometry, fluid temperatures, heat rejection rate, materials, exposure time on radiator core area, and weight. An outline of the computer program is presented in the report.
