This project funded by the Harris Corporation will experimentally assess spacecraft multilayer insulation (MLI) thermal performance. The purpose of this effort is to develop a more thorough understanding of the contribution that different parameters have on blanket performance and generate design curves to allow for more accurate system-level modeling of blankets for application to large deployable space structures. The team will develop a Design of Experiments approach to perform MLI Heat Leak testing to characterize thermal transport property characteristics and develop design guidelines associated with each variable studied.
