Abstract : A combined experimental and analytical study was conducted to determine: a. the feasibility of numerically predicting the thermal performance of multilayer insulation systems and b. scale modeling techniques and criteria for multilayer insulation systems. Analytic considerations were utilized in the development and interpretation of scale modeling criteria applicable to multilayer insulation systems. Experimental tests were conducted to obtain data for the evaluation of the performance of three geometrically different insulation systems. Numerical methods were applied for the calculation of effective conductance along layers of insulation and in the evaluation of the overall system performance of the three experimental insulation systems. The results of this U/A report indicate detailed numerical methods can successfully predict multilayer insulation system performance and can provide scale modeling techniques for multilayer insulation blankets.
