Filament winding technique permits rapid fabrication of 6m or longer segment in one piece, and ability to align reinforcement with primary stress. Vacuum quality may be insufficient. The composite is less stiff but stronger that ceramic. This is made of a 0.13 mm thick Inconel tube with 1mm thick Inconel rib brazed to the outside, approximately 50 ribs per meter. The very thin tube wall limits eddy currents.
Simulations show the design to be extremely temperature limited.
Forced cooling is necessary. By adjusting the rib spacing, the mechanical strength of the design is adjustable. The brazing of such thin parts may be problematic. The tube material is very fragile. Water-cooled Tube Simulations give reasonable temperatures.
