I was reminded of Drone assisted launching of a Lift Kite by an article on drone checklist planning.
In this case the drones are pulling lines to assist in cable pulling.
One of the largest U.S. electric and gas utilities recognizes cost and time savings to be just a few of the key benefits of using drones for tasks such as power line repair following severe wind events. During post-Hurricane Maria restoration work, Southern Company pulled 72,000 ft of rope for conductor wire using drones — a project that previously would have taken six to eight months was completed in just eight weeks.
A few years back I did some very cheap experiments with deploying a lift kite from a lifted bag.
A pre lifted kite in a bag can help to launch above calm ground air.
The idea was
Simulating having a drone lift a lightweight kite up to altitude in a sock. When the drone is high enough (and downwind) the kite tether tension is used to pull the bridles and kite out of the sock… This is akin to a fairly standard throw deployment for a ram air or single skin kite or parachute.
The obvious issue with this scheme is that the kite and drone separate so maybe you need a recovery drone manoeuvre, you also need to repack the kite to a launch sock on the ground to restart.
@floba Florian from KiteKraft had a scheme proposed at AWEC2017 (I think it was ; maybe it was 2015)
whereby the drone lifting device would be affixed to the tether near the bridle point. The lfit kite would be inverted fro the lift up to higher air. The advantage of the scheme was that the kite and drone stayed together and didn’t need reconnection (Sorry Florian I never really took to that idea. To me, the launch dynamic looked awkward)
