Sonar experts: How much sound crosses a layer?

[Bellman]

Very educational but still not sure how relevant to sim actualite.

I think OKO has a point about the 'gap' - the changing turbulence characteristics around the hull with speed.
MSGallileos photos of the Virgimia 's wide apperture flank arrays prompted my remark:

I just feel in my bones that this rigout should give better prow and stern arc coverage. Flow turbulence is not uniform
around the 'sides' of the sub. compare air flows in wind tunnels around very similar shaped aircraft fuselages.
Turbulence can be at reduced levels in 'certain' areas.

This may or may not be relevant as the apperture spread may just overcome the barriers of migratory turbulence.

But the manouvering for ''clearing the baffles'' takes on a new meaning when the hull side blind spot moves position.
It means that not only are these 'spots 'transitory but it may mean that certain areas may become relatively
more receptive depending on speed and angle of inclination.

But when one returns from 'Space' the acid test is what can be modelled in the sim and what is ? :hmm:
