Conductive Connection Library

Standardised Thermal Connection Hardware Library

The Conductive Connection Library is a 10-kilogram standardized collection of thermal hardware—comprising bolts, brackets, clips, and thermal interface material stacks—that establishes repeatable conductive heat paths across ten distinct interface geometries. In the lunar vacuum, where the complete absence of atmosphere eliminates convective heat transfer amidst 300 K temperature swings and 14-day nights, physical conduction governs system thermal equilibrium. Documented per ECSS-E-ST-31C standards, this passive hardware requires zero power, achieves a 100-year operational lifetime, and maintains a 1,000,000-hour mean time between failures through calibrated bolt-down torque patterns across Lunar Ark structural assemblies.

Standardised library of thermal-connection hardware (bolts, clips, brackets, TIM stacks) ensuring repeatable thermal connections across the Ark.
