A balloon apparatus is provided having (1) a cage structure that includes (a) a plurality of vertical tendons, where each of the vertical tendons includes a first end and second end, where the first ends of the vertical tendons are all connected to one another and where the second ends of the vertical tendons are all connected to one another and (b) one or more horizontal tendons, where each horizontal tendon is attached to each of the vertical tendons at a corresponding level of the cage structure and (2) a balloon envelope, where the balloon envelop is arranged inside the cage structure and inflatable within the cage structure.

Superpressure balloon envelope cage structure and rigging technique

An inflation diffuser including a non-rigid first section having a passageway for the passage of lift gas passing through a fill port positioned on a balloon envelope, a porous and non-rigid second section attached to the non-rigid first section, wherein the porous and non-rigid second section is comprised of a mesh material, wherein the non-rigid first section is less porous than the porous and non-rigid second section, and wherein the porous and non-rigid second section is not in contact with the balloon envelope at the end of an inflation process to direct lift gas towards the center of, and away from, the balloon envelope.
