Thermal design and analyses of Skylab multipurpose furnace and experiments

The Skylab multipurpose electric furnace was designed to accommodate eleven different materials processing experiments with their respective thermal requirements and constraints. Extensive prototype and ground-based tests were carried out and detailed thermal analyses were performed to ensure that these requirements and constraints are met. The basic features of the multipurpose electric furnace and the eleven experimental cartridges are outlined. The design and development problems encountered and the solutions to these problems are discussed. The analytical techniques used for thermal design and analyses are described.

System design considerations for free-fall materials processing

The design constraints for orbiting materials processing systems are dominated by the limitations of the flight vehicle/crew and not by the processes themselves. Although weight, size and power consumption are all factors in the design of normal laboratory equipment, their importance is increased orders of magnitude when the equipment must be used in an orbital facility. As a result, equipment intended for space flight may have little resemblance to normal laboratory apparatus although the function to be performed may be identical. The same considerations influence the design of the experiment itself. The processing requirements must be carefully understood in terms of basic physical parameters rather than defined in terms of equipment operation. Preliminary experiments and analysis are much more vital to the design of a space experiment than they are on earth where iterative development is relatively easy. Examples of these various considerations are illustrated with examples from the M518 and MA-010 systems. While these are specific systems, the conclusions apply to the design of flight materials processing systems both present and future.

Thermal conductivity of liquid InSb and liquid Ga.

The mean thermal conductivity of liquid gallium was measured as 70 (plus or minus 7) W/m/K over the range 250-550 C. For indium antimonide, Kl = 2.04Ks at the melting temperature with Kl = 9.23 W/m/K- as a reasonable absolute value.
