✦ Synopsis

Thermal and evacuating performance can be improved by means of slotting a number of one dimension slots on reflection shields of the multilayer insulation (MLI). The influence of slots on thermal radiation and gas conduction heat fluxes are theoretically studied. Based on the analysis and test, the optimum slot rate and length have been obtained. Experiments also show that the performance of MLI with slotted shield will be further improved if a combination of slotted shields with different slot rate can be used to fit the interstitial pressure distribution.
