SL@ rest...........55..............62.............58
SL@ 5knts.........57..............65.............60
SL@ 20knts.......64..............73.............68
So under LWAMI the Seawolf at 20 knots is already very close to the sound level of a 688 at 0 knots. (64 v 62) All those numbers (I believe) presume you are not cavitating. |
Yes I'm aware that they were talking about the original 688. I'm using 25 knots as reference. That traveling at 25 knots the Seawolf is still running silently. And I take it to emit a noise level equivalent to that of a 5 knots travelling improved 688. as for numbers well I'm not an engineer. So I set it to a value which I think from my simple testing is appropriate. Hunches and estimate guessing did the trick.
At the current level of my modification the Seawolf is already very quiet but you can get killed in your Seawolf too as I've experienced. A torpedo dropped from the Seahawk got me
