WEIGHT OPTIMIZATION OF A SEMISPHERICAL RADIATOR,

Abstract

A method is proposed for determining the dimensions of a hemispherical radiator of minimum weight consisting of a single central disc with several perpendicular quarter-discs. It is assumed in solving the problem of optimization with respect to weight that the surface to be cooled is a hemisphere equivalent in area to the actual surface being cooled. The methods of dimensional analysis are used for derivation of a system of integrodifferential equations for the heat balance in a sector of the disc and the incident radiation on various sections of the radiator in terms of the physical and geometric parameters of the individual components of the radiator and the unit as a whole. This system of equations was solved by the method of successive approximations on a digital computer. The results are given in the form of graphs for various numbers of quarter-discs assuming various radiation fluxes. (Author)
