Abstract: Aspects of the technology relate to temperature regulation for high altitude, long duration balloons, such as balloons that operate in the stratosphere for weeks, months or longer. A balloon covering overlays the balloon envelope, providing an opaque or otherwise light-reflective layer with low emissivity that blocks or reflects optical and/or infrared light. Heat from within the envelope is reflected back from the covering toward the envelope, while light from the sun is reflected back towards the environment. An active venting system is employed to draw in cooler ambient air from the external environment while expelling warmer air from within the envelope. Vent and air intake assemblies of the active venting system are actuated in view of current and/or predicted balloon conditions to regulate internal balloon temperature. This approach reduces repeated pressure changes, which can put undue stress on the balloon envelope and adversely affect the operational lifespan of the system.

Abstract: A method for constructing a balloon assembly includes inserting balloon envelope material which will become an apex of a balloon envelope into a platen opening of a platen; flaring the balloon envelope material outward over the top surface of the platen; positioning a termination plate over the platen opening and within the apex opening; and folding at least some of the balloon envelope that overlies the platen onto the termination plate. The balloon envelope material further includes an apex opening.

Abstract: The present disclosure provides an apparatus for use on a balloon having a balloon envelope. The apparatus includes a frame body comprising first and second members, an adjustable arm attached to the first member and a circular heating element disposed on a surface of the second member. The adjustable arm may be configured to cause the first member to move in a direction with respect to the surface the second member. The surface of the second member may be arranged to receive a termination plate and a portion of a balloon envelope. By moving the adjustable arm between first and second positions with respect to the surface of the second member, the termination plate and the portion of a balloon envelope are pressed together. In this regard, the circular heating element, when activated, is configured to cause the termination plate to heat bond with the portion of the balloon envelope.

Abstract: A high altitude or stratospheric balloon system may include a balloon envelope including envelope film, at least one tendon, and a suspender. The suspender may have a first end attached to the envelope film. The suspender is arranged to stretch such that the first end moves towards an equator of the balloon envelope as the balloon envelope pressurizes in order to control movement of the envelope film relative to the tendon and towards the equator as the balloon pressurizes.

Abstract: Aspects of the disclosure relate to techniques for manufacturing a balloon envelope. In one example, a first sheet of material for a first gore of the balloon envelope is provided. Lap seal material is arranged at least partially on the first sheet of material. A first heat seal is created between the lap seal material and the first sheet of material. A second sheet of material for a second gore of the balloon envelope is arranged over the first heat seal. A second heat seal is created between the lap seal material and the second sheet of material such that the lap seal material is configured to provide additional structural support to the balloon envelope.

Abstract: Aspects of the disclosure relate to manufacturing balloon envelopes for use in high-altitude mesh networks for packet-data communications. As an example, a gore portion may be placed on a table such that the gore portion overlies a groove within the table. A tendon may be placed on the gore portion and within the groove. A portion of tubing may be placed over the tendon. The tubing may have one or more surface openings. Restraining tape is applied over the one or more surface openings in the tubing. A constant force roller is applied to secure the tendon to the gore portion and to secure the tendon to the tubing. As an alternative or in addition to the surface openings, double-sided restraining tape may be placed between the tendon and the tubing. The tubing and restraining tape may prevent undesired lateral and longitudinal movement of the tendon during deployment.
