Speed or Cavitation - Page 2

Just curious to which performance our virtual skippers would hypothetically prefer. I've been reading as much as I can find on pumpjet propulsors performance (which is scarce info) and came across an article that suggest that some pumpjets designs are better at reducing cavitation, but may actually detract from maximum thrust, while other pumpjet designs can increase the amount of thrust but are more prone to cavitation.

Of course the ideal is one that increases thrust and reduces cavitation at the same time, which may or maynot be the reality. :hmm:

EDIT: for an SSN not an SSBN
