Wheel orientations required by Cubodal Turbines in fluid dynamical capacities include one applicable to a mobile artifact type that exhibits a fundamentally different relationship with the medium it functions in.


More specifically, the free, microcosmic, and unshifted cubodal wheel may be oriented such that one of its hexagonal planes parallel the surface of intended travel or operation. The rotational axis of such a "disc" is still through opposing triangles, but because it is oriented perpendicularly, it is more of a turning axis.


A most easily evoked use of the disc is that of a communication satellite.
In such case, the surfaces it co-planes with are polar or sub-tropical orbital planes coinciding with the macrocosmic wheel's hexagonal planes.


A simple way to grant the disc preferred motion is to join one of its half octahedra with another half at their square faces to form a full one; and then adjoin to its triangular face a tetrahedron - to in effect form the leading point of a bow.


Most options afforded the transport template are applicable to the disc, although with hexagonal shifts, expansions, and extensions, its form as a whole must remain unshifted to retain its turning dynamic. Linking configurations explored in Part IV enable incorporation of control and stabilization planes such as aeronautical tail fins and marine keels, as well as docking schemes for transport template-guided personnel and supply shuttling craft exemplified at the stern of the disc.


As it turns out, the direction-imbued disc exhibits a distinguished square, much as the coaxially-aligned geocentric cuboda does equatorially. Accordingly, 3D cubical lattices may adjoin these particular disc squares (without links) in alternative localized expression of celestial cube unity in the context of fluid freedom.


With such other dynamic uses of the cubodal wheel addressed, static applications are explored in  Wheel-based Shelter, topic 3 of Wheel Extrapolations.
