Well that hstt facility is where they test the hydrodynamic models of the ships and subs ? All the current batch and cleared upcoming batch ship models were studied there ? that towing tank facility could test models up to 3.3m/sec astern speed with the existing towing mechanism, max prob 4m/sec. They upgraded hstt speed to 7m/sec and the higher weight model towing mechanism this year so obviously in mind to test new gen of ship/sub models there?
Excellent job!
47 knots for P77? Where is that figure from?
P.S. Do look into including Chinese/Western SSNs for comparison in a v.2
Just a linear progression based on the Arihant's & the P77's power to weight ratio. Not to be taken literally.
I was thinking the same.
I was thinking Virginia, Astute, Suffren, Yasen, Type 93.
Again, the usual disclaimer, Figures marked with a Tilda (~) are my guesstimates. Don't take those numbers literally.
P77's power to weight ratio is suspiciously close to the French Suffren. Maybe the increasingly frequent exercises with the Suffren class aren't for nothing. If the P77's hull has a similar co-efficient of friction as the Suffren, then the P77's handling characteristics would be somewhat similar to the Suffren.
There is a dearth of data regarding Chinese sub's reactor & propulsion. So, almost everything is an estimate.
The 093 has 2 x of those reactors. So 150 MWth total.
