Tendon placement for high-altitude balloons

摘要

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.
