Again, @PierreB I think there has been a jump to conclusion here, without observation of the real nature.
In terms of scaling torque systems over soft lines…
Can the kitegen carousel be considered a large scale torque system design,… driving kites continuously around a large ground ring
and
Kite turbines are able to maintain and expand their stacked ring form without using any rigid material.
I have pointed this out here on
and in physical tests where you see the kite rings expanding… e.g. look again at these rigid blades whinging around with almost soft structure between them… Both kite rings are adding torque to the set and expanding the whole cone shape as modelled… (although offset a 1/6 turn in this config)
also, compression on TRPT components is REDUCED, for similar transmission conditions when the line count is increased. This is a section which does not have to scale length. I’d happily accept any EVIDENCE to the contrary.
Also…Blade length does not have to scale with number on ring or diameter of ring.
