What about making such baffles from a moderately extensible (ie "stretchy")
material or even one with SOME ability to pass fluid such that energy is
dissipated in the process and/or you get damping?
Sure, the flexible "give" of the stretchy material would damp the slosh waves
better than a firm baffle and would be lighter in weight and easier to install inside
the tank. This type of baffled tank design may be better for a ship's smaller,
auxiliary propellant and pressurization tanks.
Often it would be preferable to use firm baffles in order to strengthen a big tank
for double usage as a tank and a fuselage , rather than adding external frames and
skin to the ship. Allen M.
I hereby release this idea into the public domain, to join "my" pistonless piston
pump concept, always providing it hasn't already been thought up numerous times
already in the last century or so, as the PPP already has ;-)
