COMPUTATIONAL ANALYSIS OF VARIABLE DENSITY MULTILAYER INSULATION BASED ON THE LOCKHEED MODEL

Lockheed model calculated density multilayer insulation heat transfer,proposed the concept of optimal layer density,and focus on the connection with layer density boundary temperature,layer density zoning,configuration layer density and optimal layer density under the change of the heat flux.Analysis of the superior region of the 3 layer density insulation structure and main effects on heat flux density change in the thermal boundary temperature range.At the same time,experimental results and calculation results can be a good match.
