## Experimental analysis of MLI integration procedure with the goal to increase its thermal efficiency

### Michał Nowak

#### Abstract

Research carried out during preparation to Solar Orbiter mission by European Space Agency showed that MLI integration solutions being used so far are not efficient enough. Therefore, there was proposed another approach to this problem. Two samples were tested to assess which MLI integration procedure is more thermally efficient: the new approach with MLI being integrated on the model layer by layer or common approach with a pocket of layers sewn together and then put onto the model. Experiments were carried out in the Space Research Centre of Polish Academy of Science. Method: Each sample was tested in vacum- thermal chamber. Both experiments were carried out in the same way with the same set of boundary conditions (especially with the same value of heat generated by capton heater alocated inside the model). Two temperatures were being measured: on the inner and on the outer layer. During the experiment the steady state was not obtained, but the steady level of temperature difference was estimated by examing the changes in temperature difference - time chart. This temperature difference is directly proportional to thermal resistance which was used as a measure of MLI thermal efficiency. Results: Bigger temperature difference, especially near the model’s edge, was obtained for the new MLI integration procedure. Conclusions: More thermally efficient is the new procedure. This effect is observed in the biggest scale near the model’s edge. In the new method insulation layers are less tight together near the edges. Implementing new solutions in MLI integration procedure can enhance its thermal efficiency. This knowledge can be helpful during preparation of space exploration missions.
