I already have that, but thank you anyway.I'm trying to see if there is a diagramme showing the various layers on the descent stage, in what order, what thickness, etc. This is not for a model, etc, but rather to help in a discussion about the thermal protection of the descent stage, uses of Kapton / mylar in aerospace, etc. |

Scott Sullivan addresses the many layers of the lunar module's thermal protection on page 193 of his book "Virtual LM" (Apogee Books, 2004). The description is illustrated with a computer-generated graphic showing a typical thermal shield and blanket comprised of 15 layers of aluminized Kapton (0.5 mm thick each), 10 layers of aluminized Mylar (0.15 mm thick each) and one layer of aluminized Kapton (0.5 mm thick) sandwiched between an outer skin heat sink of aluminum (or other material, 0.020 mm thick) and the aluminum structural skin.  |

Omit the aluminum skin from the preceding drawing for the descent stage and include outboard nickel-inconel mesh over the top deck and side panels. |
