The case for robotic launch with lifter drone

Hi,

Having a self launching kite adds cost, weight, liability and chews into low wind resource.

The question is whether a robotic lifter drone can pick a landed (resting) kite from its platform, raise it to an optimal height & downwind position then release it.

Maybe technology isn’t quite there but it isn’t too far either. A heavy agricultural drone has enough lift pick a full size hang glider or even bigger parakite.

If launching procedures takes 3 minutes, a single lifter drone could launch a dozen kites or more within an hour

It would work for both launching dynamic yoyo generators and for raising of the lifter kite for drag/parachutes or flying turbines.

Advantages:

  • Most of the time the drone would stay charging on ground, in its protected cage/tent/trailer so its exposure to elements is minimal.
  • Lifter drones are already a thing, mass produced at reasonable prices
  • They can be remotely operated if autonomous launch is yet too complex.
  • A single lifter drone might service a dozen kites spread a couple km apart

Potential problems:

  • the robotic hook/crane isn’t there yet.
  • some type of kites might still be difficult to launch - rigid or semi rigid gliders/chutes should work. Lots of bridles (soft paragliders, parachutes) are inviting for frequent human intervention.

IIRC there are now drones for inspecting offshore wind turbines and blimps (or maybe the blimp was the inspection vehicle: Slow Chat III - #316 by PierreB). In that context having extra automated hands and eyes that can inspect your kite and tether, and maybe lift the kite high up into the air sounds reasonable.

Maybe a system like https://thekitepower.com/ could benefit from it, as now its launch and landing seems cumbersome, but how would that work with such a large kite and large forces…
