India to Build 6 Nuclear-Powered Submarines - Navy Chief

I am not saying the work by russians was simply a copy but they did get valuable information which gave an altogether new dimension to their research for jet engines.

Russian tech basically is at a level where you can say, "it makes things work". It's far from " wow ! we created some technological marvel here"

There are few Exceptions. we can Start with RD-181
 
. . .
Where is it official established that it's a 83 MW reactor ?

If you go by Media reports, the same media reports also mention 70 MW Steam Turbine.

You cannot Cherry Pick what is convenient to your prejudice.

When it has been clearly stated that the output of the Turbine is 35 MW then why do you insist of demolishing a Straw-man ?

Considering that the inspiration for the ATV has been Charlie I and since it had a dual Steam Turbine serving 1 Shaft it is also possible that this is the right conclusion.

After all if the Steam Turbine gets damaged in a Nuclear Submarine it is not possible to replace it or even repair it due to Radiation contamination.

SO it is far more likely that a dual turbine arrangement is made to ensure redundancy and to extend life of the system.

OK lets wait and see then. But even 47,000 Hp for the submerged displacement of arihant is way too much. Either its a lot less or the sub is a lot heavier. At some point, some numbers are going to be finalised and we will have a clearer picture. Right now, take everything with a pinch of salt.

If you want to keep believing every single number given...at face value..from wherever it is sourced. You are free to do so.

We have tried explaining our opinions, and you don't want to accept them....fine. So let us wait and see who is right.

So you finally agreed in principle ! Cool :lol:

LOL... what is there for me to agree ? The Prime Minister himself acknowledged Russian assistance. :lol:

The Reactor however is Indian and so is the Submarine Design. You are free to speculate as to the "help" Russia gave, only make sure you provide valid link. :azn:

We are talking about jet engines here, not rocket engines. Russians invested heavily in rocket RnD...and both sides received major German input in their programs at the end of WW2....so they both eventually were quite close in this sector (various strengths and weaknesses).

But in jet engines, the USSR and Russia continue to be behind the West....for various reasons.

Your reasoning is flawed and ignores the past and the future. Its based purely on assumptions driven by prejudice.

The Arihant is a TEST submarine, a prototype. the Real Submarine for which the Reactor is designed is expected to be MUCH larger.

The Aridhaman is supposedly larger than Arihant and will hold at least 12 K5 as compared to the 4 Arihant holds.

That would mean its Tonnage would be at least 10-12000 Tons. (submerged). THAT is where the reactors extra power really comes into play.

Either that or the next few SSBN will be as slow as the Kilo submarine :lol:

The problem with LCA was its engine is not powerful enough, and now when the IN has made a powerful engine, the problem with Nay sayers is that its "Too" Powerful :lol: ............ its Alice in Wonderland.

Plz Excuse me to bring in the Rockets.
I only intended to reveal the Soviet Achievments.

Not Really.
Semyorka ( which launched Sputnik ) was an ENTIRELY New and Bold Design under Korolev.
He was Infact Von Brown of Russia.

Um, there is already talk about the need to scale up the reactor as well.

Its about achieving the right balance. There's a very important reason why aircraft do not simply choose the most powerful engine available that can be installed on a platform. Same goes for a nuclear submarine. I wonder if you know why.....i.e the trade-offs regarding bumping up power on a transport platform.

Its why I said eventually quite close (after the Saturn V program). No doubt the USSR was ahead in the early part of the space race. They mustered immense resources for dedicated investment to an objective.

But that drain on their economy and its toll on its overall inefficiency ultimately led to its breaking up. Short term gain, long term pain.

:lol: .... seriously ?

You consider a trash blog and a clueless kid writing in a rag like IDRW as "authentic" wile you sneer at Dainik Bhaskar ? :lol:

Incidental that rubbish article was removed and taken off by IDRW. So much for your "knowledgeable sources". LOL.

The SSN and SSBN under construction will continue to use the Same 83.5 MW PWR and the BARC team who had built the PWR has now gone on to build a 900 MW PWR.

So currently there is nobody working on this fantasy of yours. (Maybe except in blogs and among pdf experts)

Most Aircraft's DO GO for the most powerful engine available. Everything else is a compromise. The Ariihant reactor was designed and build after due diligence by real experts after consider its long term ramification.

THAT is why the decision to build 6 more SSN came so quickly after Arihant demonstrated full capacity. Same being true for SSBN.

In all probability the same Reactor will power INS Vishal if it ever turns into a Nuclear power AC.

You can continue to be driven by your prejudice and align it with others of your kind. Only the next time you claim something, provide credible evidence. Not Opinions masquerading as facts or blogs.

@sankranti : Just wanted to know are you a BARC, tarapur brat ?

Nope, but one of my equipments sits on the Arihant.
