Anchors and Arches Notes


Notes about your kite arch questions-
An anchor circle is very cheap compared to a full circle track of the same size and strength. Its quite simple and practical to operate powerful kite arches from just a few anchors in a circle.

Mothra1 arch-ends are a single metal ring on each side. Shackles clip nylon belt or rope leads from anchors to arch ends. Its basic rigging, nothing fancy.

Moving an arch end from one anchor to another is by attaching a new arch lead and transferring the load from the old lead to the new. This is common manual roustabout work very similar to many industrial operations, but is not an automated process.

As manual methods are overpowered by scale, direct control of special megascale belay machinery would be developed. Mega-vehicles might be the arch rotation basis. Full software-based automation would be last to develop. Keep in mind that large power plants always need human workers, who are still the best operators of many large processes.

Pulleys and a crossline can transfer arch tension from the upwind side, to haul the downwind side "to weather" (sailing term), so that rotation between anchors can be done with the arch's own power. Much less powerful winches serve for this method.

All True: A single-line AWES is easier to rotate, but elaborate flight controls are required to avoid crashing due to yaw instability and actuation failure (including saturation). If the single line parts, a dangerous runaway kite results. An kite arch has yaw stability, and does not crash by the single-line yaw failure-mode. It does not runaway if one tether parts, but self-kills reliably and remains tethered at the field.
