Svarog Hub for Mobile Geodesic Structures

I designed Svarog Hub, a Hub-in-Tube connector for mobile geodesic structures, and developed it into physical hardware. The star-shaped hub arms enter partially formed tube sockets, creating a contact-area interface with each strut. Each strut has its own retaining fastener. Five- and six-way configurations follow the frame geometry, with numbered arms and color-marked struts to assist assembly. My focus was a connection that can be assembled and disassembled while preserving the required strut directions and angles. The photographs show the assembled hub, exposed insert arms, marked struts, a double-plate variant, and equipment attached at dome frame nodes. This project combines joint design, built hardware, a static FEA example, and my experience from years of field use. The illustrated FEA reports 86.77 MPa maximum von Mises stress and 220.6 MPa stated model yield strength, giving an approximate yield-based factor of 2.54 for that modeled case. These values apply only to the illustrated assembly and its loading and restraints. They are not a certified working-load rating or a safety factor for an entire dome. The interior photograph illustrates an application, not a documented structural test.
