Partially powered gyroglider - or should I say gyrokiter.

Kiting with a normal gyroglider can only be done in pretty strong wind - right.
If we powered the rotor with 5-20 hp, we could kite in (much) less wind – or how would that be?
I guess it would be more convenient and more safe?

Could be electric, 12v 24v or 230v = Less noise.
Or simpler with a small 2T engine. Maybe mounted directly on the rotor head just as an electric prerotator motor.


8 kg / 20 lb for this 15 hp:

Ooooppppsssss

I just posted the same thoughts on a different thread.

Great minds think alike, or perhaps its fools seldom differ. :lol:

You know….if a prop blast alone isn't quite enough for the rotor; an auxiliary pre-rotator motor may still allow this type of training. An electric motor could be powered by an umbilical cord tied to the rope or cable running to the gyro. I personally prefer electric over gasoline. I think the torque frame moment would be controlled by the prop blast rope tension. This is definitely something to consider.

I agree. Maybe up to 20 hp - wonder how that would work :first: ?

Gyrokiting..

Gyrokiting..

I assume gyrokiting would be more used if it could be done in less strong wind.
With a powered rotor, I assume, you could turn up and down for the wind - so to speak.

We prefer electric over gasoline as kiting probably need to be noiseless in order to be acceptable for everybody.
Unfortunately electric will be more complicated.
Even for kiting the rotor rpm varies – how much I don’t know, but the electric motor should be able to follow these variations.

A gasoline engines output would not vary much due to a little variation in rotor rpm.
Without a proper controller, the DC motor is almost locked by the voltage and the AC is locked by the frequency.

How do we control the electric motor to behave similar to the gasoline?
AC better than DC?
Or is it an advantage the way an electric motor gives its output in relation to rpm?

Or is a noisy gasoline gyrokiter acceptable? That would be much simpler.

Hi Jens

I think it is possible to make the gasoline engine quite like Vespa motor scooter, just use correct muffler, but engine will need to be mounted on frame with shaft drive system.
