A Vacuum Lighter Than Air Vehicle VLTAV utilizes a lightweight structure paired with an internal vacuum to achieve buoyancy this allows it to float through-out a given atmosphere. The pressure differential between the internal vacuum and external atmosphere places the vehicle under intense loading. A specific structure under investigation is the celestial icosahedron, which features nine intersecting rings that have an outer diameter of 0.2032m and circular cross-sectional thickness of 5.08mm. The celestials rings are positioned in three different orientations and are analyzed both experimentally and analytically.
