Abstract: A top cap assembly is provided for mounting tendon to a balloon that has a balloon envelope. The assembly includes a plate structure having a plurality of junction portions disposed at an apex of the balloon envelope and a plurality of tendon pairs. Each tendon pair includes first and second tendon members attached to the balloon envelope. The first tendon member is arranged to cross over the plate structure. The second tendon member is arranged to engage the first length tendon member at a given one of the junction portions of the doubler plate. A fastener member is attached to each tendon pair of the plurality of tendon pairs. The fastener member is used for securing the first and second tendon members of a given tendon pair together in order to support lift gas carried by the balloon envelope.

Abstract: 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.

Abstract: The present disclosure provides a method and apparatus for turning an envelope of a balloon into a parachute. The balloon may include a payload, an envelope filled with a lift gas, and a parachute system. The parachute system may include a fuse couple to the envelope. The parachute system may also include an activation system coupled to the fuse. The activation system may be configured to ignite the fuse. The fuse may be ignitable to melt through at least a portion of the envelope to separate an upper portion of the envelope from a lower portion of the envelope. The upper portion of the envelope may be coupled to the payload such that when separated from the lower portion, the upper portion performs as a parachute for the payload.

Abstract: A balloon with a generally tubular shaped balloon envelope. The tubular shaped balloon envelope may comprise a number of gores, where each gore is shaped with two elongated edges and two vertices. The vertices of each gore may be located at the top and bottom of the balloon envelope. The gore edges may be sealed together at adjacent edges to seal the balloon such that it is airtight.

Abstract: A tendon is provided for supporting a balloon having a balloon envelope. The tendon has first and second end portions that are configured to be secured to sections of the balloon envelope and a main body portion disposed between the ends. The main body portion is configured to support a load caused by inflating the balloon envelope. The first end, second end and main body portions are formed from a plurality of weft and warp fibers disposed as webbing. The warp fibers extend longitudinally through the webbing and the weft fibers extend threadedly from side to side through the warp fibers. An elasticity of the tendon is adjusted by configuring the weft fibers along a particular weft path so as to be spaced apart in the main body portion at a certain distance from each other that is different than a spacing of the weft fibers in the ends.
