Kite Power No Tower

I’m a fanboy of Falco emotors. Chatting with Rakesh by email… It seems they might have a perfect solution for my off the shelf project needs.
A generator which can adjust it’s characteristics dependant on the kite torque and battery charging needs. Cool.
A cool feature of falco emotors is the wireless communications for generation parameter monitoring and adjustment. This will be another feature to help me with the connected requirements of the hackaday prize entry
I’m looking to gather more quotes from parties involved in Daisy production… A more accurate idea of costing will help product release.
Do you sew kites? let me know.
Wow.pe are also expressing interest in developing Daisy. That’s pretty cool.

Not sure I understand what happened at the start of this test…
The setup was all a bit different. The driver kites had their 2mm spar mast rods removed. They also had a fore ward line added between the backside elastic link and the ring red panel tether. The whole ring setup was this time lifted directly inline with the lift kite so it was under a bit more tension. The back end was held by a mast on a hillock.
Launching the soft kites in the lee of the hillock just didn’t seem to work. At least 1 was always collapsed. The ring was also compressing out of shape even after being thrown carefully into clean wind. As a kite collapsed it would often deform the ring.

Time to re-stiffen the driver kites. I pushed the rods into the green sleeves first. Missed out the blue sleeve as It was looking a bit distressed. I used duct-tape to set the driver kite rods onto the ring. hint: 3 strips, stuck one on top of the other is easier and neater than trying to add strip after strip. It’s very hard to get a finger between the ring and the sail (without releasing ring tension, always been left on so far even for packing away)

Re-try. During the initial re-launch there was a moment where the ring collapsed. Braking the wheel and pulling the appropriate driver kite tether out snapped everything back into shape. Launch went well. A thin line dropped from the lift line was paid out fully to raise the ring ~5m above the sands.

Deformations on the ring were now more constant and not causing collapse. Video needs analysis still. To be posted soon.
Not convinced that the “fore ward line added between the backside elastic link and the ring red panel tether” (catchy title) made much positive contribution. It was originally set there for pure soft kite mode.

Convinced myself now that there may be a way to let the kites adjust themselves for rotation flight direction… e.g. so that they always fly near perpendicular to the ring, instead of too far inside (crushing) or outside (inflating) the ring. A possible solution where the kite is not sewn on but set with sweep balancing lines to the ring… Certainly the ability to adjust for sweep would be good. I could sew on a sweep tension strap between the kite cells and the ring. This is where I start to need a sewing team. Any offers?

I have one jumbo power sled 36 joker lift kite and had problems yesterday with it flying erratically in a chaotic wind field.

Today,
Attaching to spread anchored tethers and cross linking the bridling to the tether arch allowed me to greatly stabilise flight and maintain good lift.

I’ve probably read that description of how to solve the problem before…
But here’s the video

OK, yesterday got a bit hairy scary. This was Daisy 3’s toughest test yet.
The back of my parents house has a terrible wind field for a kite flying. A small patch of grass crowns a small steep hill covered in pine trees and granite.
The wind was super gusty because it rolls off much larger hills close by. The strongest wind I have yet tested in.
Perfect for kite survival testing. Turns out to be a good human survival test site too.

I thought I’d be smart and do the test alone. (?) The test plan was to fly Daisy 3 further downwind, underneath the lifter tether, suspending the Daisy 3 lift line from a point high on the lifter tether. But I was rushing to show off to the ferry passengers who would be going past in 5 minutes.
Things quickly went wrong when I thought I should fly the lifter on a long single tether; to avoid the down draft over the hill… oops! This meant spare tether line loose at the top of the hill at launch time. I imagined a “clean” launch and flight. Wrong! It was far too windy for that! I knew the dangers but stupidity and bravery took over. During launching as I paid out a little tether, the lift kite swung and yanked wildly. Did I have my gloves on? no doh! It was all I could do to wrestle the lift kite back down away from the wee cliff edge.

Still not being to overly bright, I re-rigged a single shorter tether. Now I could launch safely. Ah but the flight was hugely erratic. (Peter Lynn describes why)
With a bit of safety in mind. I rigged a wide split dual tether. Lines at about 110 degrees arc. Stability improved a bit but the kite was still surging and swaying ~40 deg from average downwind.
I attached the lift line which gave a further slight steadying influence.
I should have also split the lift line, bridled it onto the two tether lines… but instead I attached directly to the lifer kite bridle point.

I carried on and hoisted the back end of Daisy 3 sufficiently to start spinning… Blimey was it ever going round fast. Good power against the brake. Sometimes with wind shifts it seemed to be pointing near vertically. But it was a short test. Around 5 mins of battling Human VS wind. I had rigged the lift line poorly with no good way of cleating and flying single handedly. I was holding the lift line end in my braking hand.

The wind won in the end. I was quickly knackered. This was a high intensity sport test. An even shorter 2nd test, was followed by the start of a third. When I noticed the same T piece shear fracture as had happened previously had now happened to another old design T piece. Test over pack away. First sensible decision of the day.

I need to move to a more stable lift platform. KPower style.
Possibly going to cooperate with skybums on this.
