Jannis Wacker Structural optimisation of AWES with rotary transmission

[PierreB]

@PierreB

FIG. 85 is a side perspective view of the sixty-fourth embodiment, having buoyant horizontal axis type rotors, held by torque transmitting lashing, with no central shaft.

SuperTurbine (tm) and Serpentine, and other torque transfer systems

The catenary sag effect as the shaft length increases could be mitigated or even eliminated if each rotor had its own lift. This could perhaps be achieved with blades filled with helium or hydrogen, like on the figure 88 of US6616402 (SuperTurbine ™): [image]

This is an interesting feature to allow some scaling potential. The devices represented in the figures 85 and 88 and some other figures are concerned. Sometimes older designs include some solutions that can be benefit for the newer.

Precision: the document under discussion mentions in the limitations 7.1, page 46, the question the catenary shape with regard to the weight and length of TRPT as I have done.
