F16 is still one of the most capable fighter machine in the world ... I agree with you Singha Sir

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...

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.

''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 ...

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 ??

Scorpene submarines and DCNS built other subs use electric propulsion motor and systems from CONVERTEAM

Shiv Sir,

Slide 9 shows a cutaway section of a fuel cell based electric propulsion system in a German sub.

Its going to be Rafale for sure !!!!

Sir(s) From the Siemens website: http://www.industry.siemens.com/marine/en/solution/pma_detail.htm?id=795&family=SINAVY&PIdent=&SIdent= Continuous rpm adjustability throughout the entire operating range Elimination of torque-free speed range switching, thus no high current peaks or switc...

In case of the Siemens electric propulsion motor the RPM can be varied.

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...

Flying the Rafale is great experience atleast on MS FSX

A combination of MiG 35 and Rafale fits India well (unless the babus and ministers bungle it and we have a selloff)

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...

''mig-35--good jet,,but buying it may increase dependence upon russians,who like gorshkov may then start severe arm twisting f-16--towards end of service life,,,porkis have thenn,we need to get something new f-18---less tech transfer and slow speed,,heavy typhoon---high cost,,still no aesa,,aesa onl...

Very good analysis of the Phazotron Zhuk AE/ASE AESA radar



http://www.ausairpower.net/APA-Zhuk-AE-Analysis.html

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 ...
