Snow Sir, Its encouraging to note that BHEL, Kirloskar, Crompton Greaves etc have the ability to produce electric propulsion motors for our nuclear and conventional submarines meeting all the parameters and operational characteristics of the Navy. I presume the induustrial R&D in India especiall...

Re: INS Arihant (ATV) News and Discussion -2

The latest in marine propulsion is magnetohydrodynamic drive or MHD propulsor

Toshiba had produced MHD propulsor for a Japanese surface ship few years back and US Navy are considering this as future prime mover.

Re: INS Arihant (ATV) News and Discussion -2

''Because the Arihant has a mechanical drive. Face it, behind all that fancy schmanzy stuff, the direct mechancial connection is more efficient, reliable and has higher performance. The electrical drive has no particular advantage in a nuke boat. '' Does that mean direct mechanical connection (prop ...

Re: INS Arihant (ATV) News and Discussion -2

Hon'ble Sir(s),

The million $ rather the crore rupees question I have is:

Who in India is manufacturing such electric drive for INS Arihant's propulsion assuming that Arihant will have an electric propulsion??? Or is this still a foreign component from Gemany, France or potentially Japan ??

Re: INS Arihant (ATV) News and Discussion -2

The official DAE illustration of INS Arihant (as in Shiv Aroor's blog) shows electric propulsion as the prime mover for the prop (powered by electricity generated by the nuclear reactor - steam turbine combine). This is a radical design and will make our Arihant silent and stealth when it comes to n...

Re: MRCA News and Discussion

Can somebody say whether our indegenous Air Defence Ship is CATOBAR or STOBAR? As far as muy understanding goes both F 18 Super Hornet and Rafale are CATOBAR. MiG 29 KUB is a STOBAR a/c for INS Vikramaditya which is essentially STOBAR. Will the MRCA tender take into consideration naval variants of R...

Re: MRCA News and Discussion

Mirage-2000-H has served the Indian Air Force extremely well and there is no doubt about their reliability and battle worthiness. They have also proved to be one of our frontline fighter aircraft. Now with the upgrade (Mirgae-2000-V) the IAF will be extending the lifespan for some more years. Would ...
