About
The Load-bearing Structure of the Enclosure Type 6 is a cylindrical grid shell made from carbon-fiber-reinforced plastic (CFRP) with two interface rings, produced by Glavkosmos for spacecraft bus construction. Its purpose is mounting spacecraft subsystem structural elements and equipment, forming the primary load-bearing shell of the spacecraft enclosure. It has been flight-qualified since 2000. This configuration cannot accommodate a high-pressure metal-xenon tank unit. It has the widest fin angle in the family: 7.5 degrees between intersection nodes of spiral fins and 73°2′ between adjacent spiral fins, with thicker spiral fins (6±0.5 mm) and circumferential fins (3±0.5 mm); both interface rings use CFRP based on M46J fiber. Distance between circumferential fins varies from 64.1 to 186.3 mm along the structure. Glavkosmos can adapt the design to individual customer requirements on request.
