I am planning a launch tower with 8-foot, 3/4" tubular aluminum guides
set within a multiple halo structure. My question: will the exhaust
and flame from a minimum diameter 320n/s motor rocket (which will be
less than a half inch from guide tubes) corrode/wreck the guide tubes?
I know I could use steel but for various reasons I really prefer the AL
tubes, which are plenty stiff.
