The Performance of a Double-Guarded Cold-Plate Thermal Conductivity Apparatus
The insulating effectiveness of multilayer insulations and the influence of different physical conditions on their performance are of prime importance in the use of liquid hydrogen in future space missions. To better define the problems associated with the storage of liquid propellants in space  we are investigating a number of variables which influence the thermal performance of the multilayer insulations. Considering the conditions under which these insulations may be used, the effects of the following variables on their thermal con« ductivity are of particular interest: (1) boundary temperatures; (2) gas pressure; (3) gas type; (4) mechanical load; (5) number of shields and thickness; and (6) thermal shorts and discontinuities.
