This week in rockets


Another bit of video surfaced from USlaunchreport. To someone who works in industrial plants, this kind of piping looks normal, but it's quite outside the normal human experience.

Of mane interest is how they routed propellant to 9 engines in the most efficient way, how they prevented cavitation, & the enormous number of wires heading to where the intake pipe is. That would be where the ground service arm attaches. 1st stage tanks would be filled from the base. 2nd stage tanks would be filled by pipes higher up. All pipes are as short & narrow as possible, yet it still takes a very big pipe of LOX running down the middle of the fuel tank. The pipe would be completely full at liftoff, forming a significant part of the total capacity.

The manufacturing of the manifold would be quite a sight, from above. More likely the top side can only be seen after an explosion, since parts would be added from the fuel tank down.

As a pipefitter / plumber , I can really appreciate the work here . This also looks as if the pipe chase runs are paralleled up as a type of 'heat exchanger' between the layers involved . Transfer of LOX heat dissipated during the transfer . Depending upon how one views each layer ; pre-heating or pre-cooling by conduction .
