Abstract

Methods and systems for wrapping a streamlined tether around a drum are provided. The tether can be attached to the aircraft. The method may involve directing a streamlined tether around an exterior surface of a drum, wherein the drum includes a helical step around the exterior surface configured to engage at least a portion of the streamlined tether and pass along the drum The longitudinal axis superimposes subsequent layers of wrapped tethers in a staggered fashion. The streamlined tether may be guided onto steps using one or more level wraps.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 14 / 142,910, filed December 29, 2013, which is hereby incorporated by reference in its entirety. Background technique [0003] Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0004] Wind is a renewable energy source. Traditionally, wind energy has been used to tow water or land vehicles by utilizing sails. However, sails are typically positioned close to the ground and do not take advantage of the stronger winds at higher altitudes. An aerial vehicle can be used to harvest energy from the wind at such higher altitudes to turn a generator. Such an aircraft may be coupled to a generator using a tether. When not in use, the aircraft and associated tethers can be stored. Contents of the invention [0005] ...
