Toward the worst AWES

Your experiments are useful.

Concerning “using a rod and a bend in the rod”, the wind force will push the rotor in its direction as for a rod without bend. For this configuration a large enough lifter kite (1) would be required

To offset the rotor angle to the line angle you would need, I think

• A high enough line tension (above and below the rotor) (which is a given since here we are talking about a yoyo system)
• Enough rod length below and above the rotor so that the moment from the wind pushing on the rotor does not overcome the moment from the line tension.

@PierreB

But the answer to my question would be negative with the tested rotor because of its low L/D ratio (once tilted) of about 1/3 :1: this (0.555 m diameter) rotor generates more drag than lift.

So that would have it pulling at roughly 18 degrees. You could try to experiment, for example with the setup I described above, if you can get it to pull more upwards than that with different rotor angles. That should be possible otherwise autogyros wouldn’t be a thing I think.

Now this is a related topic: Bryan Roberts' Gyromill (Sky WindPower) the line tension and the rod replace the tethered autogyro. The question of interest is, have they found a rotor inclination that works for them?
