Sukhoi PAK FA

So simple case of d1ck measuring contest you're saying ?

The article came to a wrong conclusion. That's all.

01-1 undergoes testing:

A possible configuration of "switchable VLO" facilities in the intakes (compression ramps + protective grid panels):

Supersonic flow braking trajectory and compression leaps:

01-3 undergoes testing:

MRAAMs sizes comparative to MWB size (a possible future changes):

A possible arrestor hook location (just speculations, but...):

A video about T-50 (there are frames with protective rams are there):

Broadsword: Russia can't deliver on Fifth Generation Fighter Aircraft: IAF says

A lot of this already contradicts what has already been officially been stated.

For eg: Browne said that FGFA technical specs were already transferred. The Item 30 was chosen for FGFA's engine. HAL Chief Baweja is on record saying the new engine will be ready for induction in 2018 and that final FGFA prototype will have this engine. Semi-official confirmations of new GaN modules for PAKFA's radar. There won't be an equivalent in the world.

Of course, it will be expensive. Not a lot can be done about the costs. We obviously won't be able to afford the aircraft if our GDP growth stays as is. As for stealth and performance inadequacies, we don't know how advanced those specs are or whether the engine makes the difference. If they have taken the 117 as its basis, then there will be inadequacies with both. But if there are inadequacies while Item 30 is installed, then there should be a re-look of priorities.

But what I dont understand is what do we have to gain from it? They definitely wont part with their best tech and we should not expect them to. It might be the best anywhere in the world but what is our contribution? What do we learn that we dont already know. Lets buy 100-200 of these fighters. Want to see them in Indian colours. Nut why this 6 billion $'s for development. See how the program turns out and ask for minor customization like the mki later. Sink the funds into AMCA instead and go for a JV for technologically critical areas like engine and radar.

They are going to provide full ToT. Most of the negative noises are from media sensationalism. Even that F-35 source code ToT story was BS according to an Australian Vice Admiral. The media sensationalized a non-issue.

It might be the best anywhere in the world but what is our contribution?

One wonders. We don't know yet and what we have here are again media speculations. We only know we will have some part in increasing the composite content of the aircraft and make subsystems, but nothing clear beyond that.

What do we learn that we dont already know.

We don't know. This is our first time designing a 5th gen too.

Lets buy 100-200 of these fighters. Want to see them in Indian colours. Nut why this 6 billion $'s for development. See how the program turns out and ask for minor customization like the mki later. Sink the funds into AMCA instead and go for a JV for technologically critical areas like engine and radar.

Without sinking in the $6 Billion, we won't be equal partners and we won't be part of the development process. We will end up being in a buyer-seller relationship. We call Brahmos our own missile because of such a JV. It will be the same with FGFA too.

With the JV, we can do whatever we want to the aircraft in the future, no different from LCA or AMCA. Of course, most of the work will be done in Russia, but in the future we can do our own thing, like what China has been doing with the Flanker.

PAK FA (and FGFA of course) already has GaN based TRMs in all its radars.
This is confirmed oficially:

bmpd - Развитие программы ПАК ФА
isvch.ru/files/recl2013.pdf

At the moment the following specs has been achieved:
GaAs modules Fmax > 650 HGz
GaN modules Fmax > 1700 Hgz

This is unparalleled specs throughout the world. Noone could do this at the time.
It seems, the PAK FA will be the first production plane ever with GaN-based radar.

Gunning for the PAK-FA: What the IAF really wants | idrw.org

So what I posted before was true. IAf is afraid that PAKFA will be less stealthier than both J-20 and J-31.

Thats why they are accusing the russians of failing to give design info which will help them improve the stealth specs of FGFA.

Yeah, Indian "experts" who cannot create nothing in stealth technology afraid of J-20 and J-31 without knowing their exact (or even preliminary) RCS (as it is secret in any normal country).
Don't be rediculous.
All of these movings are inspired by those part of IMOD, who will suffer in the case of Rafale purchase will be reduced in numbers (we all know about the IFM demand to shorten military expances).

Gunning for the PAK-FA: What the IAF really wants | Russia & India Report

The IAF has five major complaints: the PAK-FA is too expensive, its engine unreliable, radar inadequate, stealth features badly engineered, and finally that India's work share is too little.

Regarding IAF's recent brawl about PAk-FA 's developmental program

these concerns have some significances & some concerns are total rubbish



Rubbish concerns

i) its engine unreliable,
Stage 2 engine of PAk-fa is yet to be developed & inducted but IAF is howling it's unreliable. Strange!!!

ii)radar inadequate
OMG!!

does 5 set of radar arrays (3 X band + 2L band IFF) is not sufficent for IAF that they want more. do they want rotary radome antenna like AWACS on pak-fa or what!!

on top of it GaN modules development has kick started in russia

iii)PAK-FA is too expensive,

but russians claim it would be far more economical than western counterparts or IAF is comparing it's price with chinese counterparts.

If the latter one is the fact then i am sorry no country can match china in building cheapA$$ planes in this planet.

Significant concerns

i)stealth features badly engineered.

Hmm!!
may be IAF dont want to see Pak-fa engine face through it's air intakes at all & it' rear aspect appears to them more bumpy than indian roads.

But hang on a second
does even the russians have tested their pak-fa protypes for RCS evaluation yet or perhaps the IAF has swallowed upon Kaapo's P.O algorithm B.S that chinese J20 is more stealthy than PAK-FA

India's work share is too little.

hmm !!
thats also a valid point & ofcourse BTW what exactly can we contribute in pak-fa that is the main point ???

as if we have light years of experience in building indigenious planes am i right !!!


CHEERS

If you'll look at all the stupid shit that US media bulls for US hamsters, you'll be afraid for American nation psychic health

You'd better look at the new photos :thumb:
