Q: How are pressure-resistant joints engineered?
A: Double O-ring grooves with hydrostatic test ports. Bolted connections with tapered stress distribution. Underwater welding habitats for integrity verification. Acoustic monitoring for leak detection. Cathodic protection continuity across interfaces.
Q: What prevents cold welding in deep vacuum?
A: Nanoscale surface texturing with >0.4μm roughness. Molybdenum disulfide dry lubricant coatings. Gold-plated contact surfaces preventing adhesion. Thermal isolation gaskets maintaining differential temperatures. Vibration systems preventing static contact.
Q: How is thermal management achieved?
A: Phase-change material capsules in cellular voids. Heat pipe networks transferring internal loads. Variable-emissivity external coatings. Liquid circulation channels within webs. Insulating aerogel-filled flange cavities.
Q: What enables modular growth capability?
A: Standardized docking collars with robotic alignment. Pressure-balanced connection tunnels. Tool-less coupling mechanisms operable in gloves. Magnetic pre-alignment guides. Redundant seal verification systems.
Q: How is radiation shielding integrated?
A: Borated polyethylene modules in cellular spaces. Regolith-filled compartments for planetary surfaces. Hydrogen-rich polymer cladding layers. Electromagnetic deflection coil mounts. Self-repairing microcapsule composites.
