About this file
The provided documents are technical engineering drawings for two custom copper heat strap assemblies for a NASA cryostat system. Both drawings detail similar specifications for copper heat straps with the following key technical characteristics:
The first drawing is for a Mercury Cryostat 3K Strap, featuring copper brackets connected by 0.25" copper braid, with 6 x 0.19 and 14 x 0.20 hole configurations. The second drawing is for a Mercury Cryostat 50K Heat Strap, with a more complex curved design and similar construction methodology. Both designs emphasize high thermal conductivity, low vibration, and flexibility, with braids welded to copper brackets and full assembly to be annealed after fabrication. The material specified is Copper 101, and the drawings include detailed dimensional specifications, cross-sectional views, and 3D renderings of the proposed heat strap assemblies.
