Best is still using it, or not anymore?edt wrote:we didnt know what the f*** we were doing with kites 10 years ago. We have to take the knowledge we have now about how to build bridles, kites, shapes and such and add changing the shape of the tube to it. You know those experiments with cuben fiber? that's the wrong direction. You don't want to make the size of the cylinder smaller you want to make the shape of the leading edge better.Faxie wrote: Looking at experiments in the past with odd shaped tubes and added cloth behind the LE, I don't think significant improvements will be possible without a new kind of stronger and lighter material.
The aerodynamics of a kite are not defined by tube alone, there's still a lot op cloth behind it that for a big part with it's camber dictates the efficiency. And a smaller LE can give you a better camber, and with less frontal area, you get less drag also. But with a more streamlined tube, you'll have to increase the size to compensate for the loss of structural integrity, thus adding more frontal area, increasing drag. And don't forget linedrag too. My guess is that a different tube shape won't offer any benefits. In the end you'll have the same netto l/d ratio. Not to mention a more difficult and probably weaker construction.
