Analysis of the effect of layer perforation pattern on the rate of gas leakage from multilayer thermal insulation during satellite launch

Hamed R. Najafi; S.M.Hossein Karimian; Mohammad Reza Pakmanesh

Volume 16, Issue 1 , April 2023, Pages 11-21

  One of the passive components of the satellite Thermal control subsystem is multilayer insulation. In order to prevent air from being trapped between the multilayer insulation layers, which causes the thin layers to inflate and disintegrate during satellite launches, holes are made in the layers. These ...  Read More
