Mobile units have the following inseparable sub-assemblies: a cylindrical outer envelope with low conicity or even constant section, one or more longitudinal fluidic channels, sensors, and one or more transverse fluidic channels. Each fluidic channel convergent at the inlet and divergent at the outlet to ensure the absorption of the entire frontal fluid vein. The motorizations are engineered for fluidic channeling design and each one controlled by the sensors fitted to measure differential pressures between external and absorbed fluid media. The transverse fluidic channels connected on demand, upstream to the high-pressure outlets of the longitudinal fluidic channels, downstream to pressurized boxes for vertical and directional movements. A set of volumes internal to the external fuselage envelope, not occupied by other devices of the mobile units, structured in technical operating sub-assemblies.
