For the first time you are going to see a major sub system of the indian nuclear submarines
Nuclear submarine gearbox ( most probably the picture is of the land based prototype version )
And I strongly believe 4 nuclear subs are in water ( not including the akula )
Well I got news for youWhy do you have to post something internal to weapon system.
I looked forward to your no nonsense defence r & d related postings ... Good Luck in whatever endeavor you pursue and may you excel in that.Well I am tired of posting pictures and all
I am quiting DFI for the time being
It was nice to be here
Good luck to all except for porkies, khangressis, aaptards, liberals , sickulars , presstitudes , mullahs , evengalists , commies , feminists , self flagellating dindus ie all MOFOs inshort
Keep the faith.........

Walchand .Where did you find it?
I mean which vendor website?

T90 tanks are light weight with 45 ton weight. So, 1000HP is enough for it. Arjun tank weighs 67tons and it was stated to get 1400-1500HP engines. Too high powered engines will badly affect range.New indigenized tank engines, not happy with the low output
T-90AM/SM already is equipped with 1130 hp engine. And Russia is planning to give all of it's T-90 (M, AM, A) this engine at least. If new 12H360 engine becomes economic then this 2000 hp max, 1500 hp normal output, will be given to T-90AMs. And T-72B3 and T-72B3M getting get 1000 hp engine.T90 tanks are light weight with 45 ton weight.

As usual, people are jumping the gun!DRDO two layer BMDS is going to be finished soon. And this American system is being procured. Any good reason?
1000HP is always the normal peak and not turbocharged peak. India only indigenised Russian engine and not built a new one. In 2014, th engine was 73% indigenous while it is fully indigenous now. The engine has not been changed from Russian to Indian design.T-90AM/SM already is equipped with 1130 hp engine. And Russia is planning to give all of it's T-90 (M, AM, A) this engine at least.

India using such engines which are "obsolete " even in Russian standard. 70s and 80s era engine.
And Indian T-90s use heavy armour, hence they are far heavier thanjust 45 T.
Exactly, we have SPYDER, we have QRSAM project why we do needAn american system redundantly?As usual, people are jumping the gun!
AON is the most preliminary step in the process. Most AONs never fruition!
It could just be a parallel effort to check what else is out there while desi/Israeli systems are being worked out.
That said, NASAM is not a BMD.
Nasam is a short range defense for point/small-area defence. Spyder, QRSAM will be equivalent (not AAD/PDV)
New Russian engines are not only give higher putput they are more efficient too. less prone to break down, not over heated. That's why they get priority.1000HP is always the normal peak and not turbocharged peak. India only indigenised Russian engine and not built a new one.

Tata Sumo has 70BHP engine while it has weight of 2tons, for example. In a tank, we do not need such high speed as Tata Sumo. A tank travels at an average speed of 30kmph and does not exceed 70kmph. So, going by the standard of civilian Tata Sumo, the 1500HP engine for T90 would make it unnecessarily overpowered. Overpowered engine causes fuel guzzling.
1000HP (1150HP peak turbocharged) is better than 1500HP normal output and 2000HP turbocharged output. Engine has a specific sweetspot power range whereby the fuel consumption is minimal. In diesel engine, that comes around 70% of its peak normal power. For a tank which travels normally at 30kmph, the 1000HP engine is the ideal one. Indian T90 uses better quality armour rather than the lower quality Kontakt ERA armour. The weight of the armour is not meaningfully increased overall.
The 1500HP/1800HP Bharat Power Pack is in the making for a heavier Arjun tank. So, the 1500HP engine also in the pipeline but will not be used by T90 Tanks. This is a deliberate move considering the fuel efficiency in mind. Lower powered engines are not obsolete. Engines get obsolete only if there is a higher efficient engine available, not because size of the engine is increased
Indian engines are of good quality too. Regardless of the peak power, quality of India-made engines is good enough.New Russian engines are not only give higher putput they are more efficient too. less prone to break down, not over heated. That's why they get priority.
Earlier there was a project really existed to give 1100 hp engime to Indian T-90s and instead 980/1000 hp one to T-72.It is not my personal choice, but once existed project pr recommendation.
Which is now curbed.
