K61 - Shiznit Prototype #2
This is the second prototype build for the indoor dual line kite that I am designing, the Shiznit. This prototype has a few notable differences from the last one:
Size
The previous prototype was scaled up a bit from the iTrix. I found that if I scaled it up just a bit more, I could make the leading edge rods 48”, which fits in my travel case, and is the length of the rods when I order them, so that’s a little convenient.
Width and depth
I felt like the previous prototype’s sail was a bit too deep. After thinking a lot about this, I came to the realization that the length of the lower spreaders can be inherently dictated by the positioning of the lower leading edge fitting, and the center connector. The idea is that, without tension, the lower spreaders should create a straight line through the center fitting. The leading edge then must adapt in its angle so the lower fitting sits on the line created by the spreaders. With this premise, a sail can be made wider and flatter by lowering the lower leading edge fittings, or by raising the center fitting, and cutting new rods to fit.
This prototype is built with a bit more room around the center and lower spreader fittings so that I can tinker with this ratio. I currently have it set with the spreaders as long as possible by placing the center connector at the top of the cutout, and the lower leading edge connectors closest to the wing tips. If I decide that it is too flat, I can adjust the fittings, cut down the lower spreaders, and cut out longer standoffs.
Dynamic Bridle
When flying the first prototype, I had a hard time getting it to go from a mid-air pancake into a fade. This made me think that a dynamic bridle would be interesting since it has a range of positioning under tension, which could make this more forgiving. I’ve never explicitly used a dynamic bridle before, so I’m very curious to see if I like it.
Scrap Fabric
You might notice that this kite isn’t in my usual Red and Black. I figured that, for a prototype, I might as well use up as much scrap fabric as I can, regardless of color. Well, I had a bunch of scrap gold from making the two Nova quad line kites, so here we are.
