Weight Optimization for Honeycomb Radiators with Embedded Heat Pipes

A mathematical model for a single-stage space radiator with embedded heat pipes has been developed, and graphical solutions are presented for tradeoff studies. The model allows selection of the optimum radiator sizing for spacecraft payload heat rejection. It calculates the minimum weight configuration for specified radiator parameters involving temperature, heat pipe, and honeycomb panel characteristics such as heat pipe spacing and facesheet thickness, as well as radiative surface properties and panel thermal conductivities. The data in terms of graphical form are applicable to practical engineering design applications.
