Rates of climb and descent

[Bellman]

Having noticed a significant change from SC I set out to do some tests of the relative rates

Both at 100 ft. (Same locations) Descend to 300 ft. TA deployed.

Akula 2
Descend - SC 1.8 - 39 sec. DW - 1m 53 sec. (An increase of 250 % appx)
Ascend - SC 1.8 - 41 sec. DW - 1m 53 sec

SW
Descend - SC 1.8 -44 sec. DW - 2m 19sec. (An increase of 330% appx.)
Ascend - SC 1.8 -44 sec. DW - 2m 19 sec.

At first blow this looks bad for the SW - further tests to 600 ft confirmed the disparity.

However it soon became apparent that the SW was taking much longer to level-off, particularly in the
last 20 ft or so. So when this was allowed for by measuring the time both took, to achieve the ordered depth,
but less those last 20 ft. both subs had almost identical performances.

This may not be new info. to many but others may wish to allow for this in the SW - those 20 ft. can account
for as much as a minutes loss of time, which could be vital in many situations.

I cannot help but feel that 1 minute to travel 2o ft while levelling is a little 'unrealistic' ? :hmm:

[Kapitan]

what about the speeds i made the akula hit 47knots while at flank and blowing ballast tanks

did the same for the sea wold and i hit 51

[Qppralke]

I guess the seawolf is simply faster.

Then that is still like in SC, Kapitan, when performing E-Blows from a sufficent depth.

Good point Bellman. Did you use the same speeds the same map and the same location (water currents) and did you repeat the test?

If so that's curious that the SW takes more time to level off, as the inertia should be lower with lower tonnage and dimensions i thought? :hmm:

[Kapitan]

in sc i never managed to pass 37 knots so ?????

[Nexus7]

with the Akula II load 100% air, go deep and do an E-Blow: 40 Knots. SW i didn't try but i remember bewteen 40 and 50 knots.

[Kapitan]

i did an eblow and managed about 47 knots

[Nexus7]

Kapitan i meant in SC...

[Kapitan]

lol sorry it me who become confused

[Bellman]

Nexus7 - yes to all.

I am converting to the Ak for DW after concentrating on the SW in SC/SCX2.

As you would need to know the relevant comparative performance characteristics I wondered whether SA
had adjusted anything (else) in favour of the Ak.

I cannot understand the protracted SW leveling off process, which I have replicated several times. :hmm: :hmm:

[Kapitan]

why is it when i do e blow in dw my stern is the first thing to bounce out of the water ?

[Bellman]

Mein Kapitain,

The hot weather here has led to small increase in alcohol consumption, so I am rather concerned that I now see TWO sheep.
I am sure there was only one before ?

Do you intend to let them breed ?

Will your posts be guarded by massive flocks of sheep ?

[Kapitan]

oooo yeah :P lol they will breed untill they fitt on subsim no more lol

[Bellman]

Good on you - meatey

Sorry typo - matey.

[Kapitan]

i fancy lamb for dinner

hear lenie lenie lennie come to uncle kapitain
