U214 specs says a diving depth of 400 meters. whereas our own ATV has only 300 meters. may i know why?
Depends on the material used to manufacture the hull of the sub , a HLES 80 steel is rated at a diving depth of more than 300m and a HLES 100 is rated for a diving depth of 600 m
We dont know what material the ATV will use , But If Russia assistance is any indication than its quite possible ATV should be able to dive at depths of 600m.
well the diving depth varies on many thinbgs, i am not sure abt what all.....
The Seawolf uses HY-100 steel and is rated for 500m of depth. And the only other submarine that uses or was to use the HY-100 steel was the dutch Moray class submarines, which was also to use the Swedish Sterling engines as the AIP.
the Russian subs are usually HY-80 steel, i guess the Shuka-B (Bars/Akula-II) uses HY-80 or maybe a mix of Titanium (not sure) but they are rated for a depth of 600m ..... so its my guess that HY-80 can go further down and HY-100 even further. But since HY-80 is cheaper than HY-100, many stick to HY-80 (scropene etc) , so the diving depth also has to do with the capacity of the ballast tank and how much water it can take in which also determines the maximum diving depth of the submarine.
as for the ATV, i put my faith on the Severodvinsk class.
I have a solution for the Indian Navy.
1 ) Acquire the Scorpens from the French, after forcing them to cut donw the price and making them take a vow that they won't sell a single submarine to the Pakis and provide hlep to India in the war scenario about how to detect the Agosta.
2 ) Continue negotiation with the Germans about procuring type 214 and finally start manufacture them in MDL with the integration of Russin Klub Missiles.
3 ) Also acquire Amur with the AIP and produce them at MDL
4 ) Design an Indigenous Submarine under Project 75 or 76 whatever is projected on papers and build it amalgamating the 3 aforementioned submarines's technology.
4 ) I dont' know when ATV would fructiy. If it does, it ia a bonus to the IN's submarine
Agree to the above views fully. And if u guys ask me what i want, ---- i just want all the tech from DCN, HDW and ofcourse the Russians to come home, and more so an Indian private company (mostly Tata Sons) to acquire the fully control stake in HDW from the present owner (Americans) so that the sub or tech is not proliferated at the same time we make it here and sell it to others.
5 ) Finally acquire 2 Akula II ( either on lease or puraches ). One of eastern part and the second one for the western
I might be taunted by others for dreaming something herculean. But there is no other alternative than this mentioned above.
Implementing my solution might cost a lot of money for Indian Government. But in the long run, who will make the last laugh ? Indian Navy. It will not only kick the ass of the PN, but also keep the marauding flat-nosed Chinese at bay and Indian Navy will truly emerge as a blue water navy.
well i don yhink so .... we definetely have the money in the form of a USELESS Forex Resreve which many Idiots think to be of Godly stuff to even touch with. Its the b'coz of the idiot Manmohan that the defence forces and the ordinary Indians have to pay a heavy price in their dayily living. Now the petroleum products prices are going to be increased. Again.
For any measure of the damage the insensitive and ilogical opening up of economy did can be seen from the bitter fact that, when Indian Navy was building its future destroyer inb the 80's they were dreaming abt the supersonic 3M80 Moskit as its primary weapon, with India being the first customer (& probably the only one, if we acted in). But after the 'opening-up' , what the Navy saw was that the Misile itself costed as much or more than the destroyer itself.
And what many $astardly Idiots from the Indian media say abt the stuff is that Russians are charging us too much for the systems blah blah blah ... the arseOles forgot to look into the devaluation that the idiots made during the 90s. (but not surprisingly, I'll see many supporters for that in here for sure. And my say is that U guys need to rise above personal deeds to think for the Nation at large, which most Indians lack)
well the AIP link that u posted is no good either in terms of its fairness, that guys simply have no clue (or intentional ignorance) abt the Soviet development of the AIP.
As for the U-212s endurance, I guees it mentions the endurance addition that AIP gives or is it the total endurance?? ... well i guess its the first one.
as per the naval-tec link .... it says these ----
The propulsion system combines a conventional system consisting of a diesel generator with a lead acid battery, and an air-independent propulsion (AIP) system, used for silent slow cruising, with a fuel cell equipped with oxygen and hydrogen storage. The system consists of nine PEM (polymer electrolyte membrane) fuel cells, providing between 30 and 50kW each
and this one says 120 kW --- maybe 214 ?, BTW, whats the power rating of the AIP that went into the German sub?
Performance of the AIP system has been increased with two Siemens PEM fuel cells which produce 120kW per module and will give the submarine an underwater endurance of two weeks.
so if we take the capacity of the AIP module considering that its 120 kW rather than the above 30-50kW, we get -
9 x 120kW = 1080kW is the power that the U-212 AIP modue provides. In comparison, as per the link I posted above, the Russians have said that they can produce the 3000-4000 kW module in 3-5 yrs
when given order, as they don have the budget to do it for display.
When ordered by a domestic or foreign customer, the corporation of enterprises headed by the SKBK JSC can design, manufacture and supply a high-performance electrochemical power plant (Fig. 4), boasting power ranging from 100 to 3,000 - 4,000 kW and provided with all the infrastructure required for operation, within 3 to 5 years (depending on the power and energy capacity).
and I stay put that we wasted a lot of time dreaming & droolong for something that was not so special. I hope time is not more wasted drooling atleast abt the German AIP and rather go in for a joint-development of the Russian AIP.
And to all those U-boat fans, I just want u guys to give reasons for ur choosing the U-212/4 series over others and also the reason as to y it is the best one as default. Would love to see ur reasons.
