If chinese canards doesn't effect stealth, why there isn't one on j31
There are other moving surfaces as well. Slats, elevators, flaps. All of them should then be bad for Stealth, no..?nam wrote:I don't claim to know about building stealth jets, however are you saying a large moving surface will not have EM returns at specific angles?JayS wrote:

Ofcourse they reflect. Depending on their size, amount of energy and the angle they are exposed to will drive the reflection. However the canard in question of J20 is massive,in horizontal plane and will be part of the frontal RCS. Not sure how much they can reduce it.JayS wrote:

Mig 1.44 was a prototype. Sukhoi Production PAK-FA with be without one. As you mentioned about LM proposal, however it was just a design.It's production jets are without canards. We are not doing canards, neither are Japanese.You can always design the surfaces to give minimum possible reflections in forward direction for given movement envelop.
FYI, LM's original proposal for Stealth STOVL aircraft was a canard fighter. F35 would have been a canard based aircraft, had LM not destroyed the work related to that project. They had only F22 related data handy and that's what they sent as reply to RFI. That's why F35 looks like F22.
MiG's 5th Gen prototype was also a canard jet.
Sure, you can believe anything you want, your prerogative. There was a time when people derided LCA saying all recent delta wing planes have canards and LCA does not, so LCA is bad wonly.nam wrote:Ofcourse they reflect.

Not saying it is the end of stealth,however having massive canards is not adding to it.

I would hold on to my opinion until I see a production aircraft , other than J20 with canards. I would happy to change my mind even if future Chinese stealth jets will be with similar sized canards.
Its a very genuine question requesting a factual answer. If PAKFA is the next best thing to pasteurized milk, why isn't Sukhoi/ROE proposing it in response to both IAF & IN RFPs?Mukesh.Kumar wrote:Saar, why saar?

A good decision has been taken not to spend Indian Taxpayers money on development of foreign systems for which we do not get 1. ToT or 2. Sales Royalty or 3. Exclusivity.
No one has doubted the potential ability of the aircraft or the designers. ROE/Sukhoi are free to bid in Indian RFPs.

one reason Pakfa is not contesting MRCA 2.0 could be that it is already under negotiation under separate deal. Another reason is probably because it's too big. Just like su35.

At a strategic level, It would be crazy not to have this bird in some form in the IAF. My bet is we will not see the AMCA until 2050 in enough squadron strength - it is still not a funded project.
The pakfa has already demonstrated flight characteristics that few/none can match. Yes, development continues but then how is gripen e, especially in mrca 1.0 any different?Karan M wrote:+100 TSarkar - Russia can always request that India allow them to compete in the new MRCA bid and put up the PAKFA against the F/A-18 E/F and F-16 Block 70. The PAK FA should blow these aircraft away since its a generation ahead in terms of stealth, airframe performance etc and sensors are equivalent (just going by best case Russian claims). If they are unwilling to do so, what does that tell us? About how far the aircraft has to go before it matures?
Also, I am yet to see a single Indian program which has benefited from Russian TOT in some other system. Jag, Mirage 2000 etc all have their part to play indirectly in LCA. Not so for the MiG-27 etc. Apart from the Russian guns and R-73E, I dont see what TOT for the MiGs did for India. Similarly, I am very skeptical PAKFA TOT will do anything for India in terms of AMCA program.
This is the whole dilemma essentially.ShauryaT wrote:Can we engage the Russians to NOT sell or delay the sale of its 5G product to the PLAAF?
The Chinese learnt to make phones , maybe not as good as apple but definitely workable. Licence producing aircraft with so called ToT hasn’t got us anywhere nor will it in future, be it with the Russians or anyone else. The point in this case is yes we need a 5th Gen fighter. Definitely buy one to manage risks till the AMCA comes. If the Pak-fa meets requirements buy it off the shelf with some customaziation. The thing to not do is pour billions into someone else’s MIC for R&D when everyone knows that you are not going to get any worthwhile IP or learning or tying yourself into buying over a 100 aircraft when the Russians themselves ain’t buying more than a dozen for the moment. Pour that same money into research in ones own country.ShauryaT wrote:CM: One bogey is this TOT thing. We need to be clear on what TOT is. It is the transfer of production technology. The ability to use "local" resources to produce items, even from a component level. There is NO ONE else who has offered us this opportunity like the Russians have. In many cases like the Su-30 and Brahmos and even for the Bhishma, we have indigenized the production and in the process create a veritable local supply chain. What it is not about is the transfer of IP or transfer of critical components. No one will ever provide that and the IP part has to come from indigenous research and development. Some people are asking questions like did we learn how to build engines on our own or AESA radars due to years of TOT of Russian wares? It is like asking, did China learn Apple's IP because iPhones are made in China? There have been many learnings and successful spinoffs, such as the canister design from the Brahmos project that we have successfully used for all our missiles with Russian help. We do not have to repeat the role Russia plays in our strategic projects?
ShauryaT wrote:One more point to add and I hate to be a skeptic but for every post which seeks to bank on the AMCA and dump the PAK-
FA based product, some food for thought. The LCA has taken 25+ years post funding to get to partial squadron strength, still maturing and yet to be in FOC. A reasonable approach to risk planning for the AMCA would be to assume at least a minimum of such a time frame for the AMCA. Is it possible to do it earlier, certainly but it is also possible that this may take longer than the LCA project. Meanwhile, the quantitive and qualitative requirements for national defense have to be met. What is the answer?
The Airbus type joint IP option is not on offer. Understand, We may desire it to be so but it is not. Would not like to go into details of possible reasons why. But at the same time, the type of customization on offer would probably not be available from another country.Cybaru wrote: The point really was should invest 4-6 billion dollars into this venture and get hardly any IP for it. Given that RuAF isn't adding these in numbers, all the debugging and growing pains are ours and ours alone. If this were an equal partnership with joint r&d and production (Airbus kinda model?) this would make a lot of sense! Plus this enables the product to be sold to competition while we toiled, refined and made it into a weapon.
I do not think anyone would object on the need to invest into our own MIC but we would be conflating two separate objectives. The investment into the PAK-FA project is about the acquisition of a product in relatively short time frames and hopefully with some strategic benefits to make it worthwhile to invest early. The engine venture example is about an investment into R&D in the hope of a successful future capability acquisition. Time and Risk are the key variables here.IMO, I would rather throw the 4-6 billion on engine ventures
We do not have the luxury of investing our meager resources in two different stealth fighter programs especially when one of them is not our own and will not accrue any benefits to our local MIC. Compare our R&D expenditure to what the Chinese pour into their local programs. The AMCA is still waiting for funds. It deserves whatever we can spare. For the IAF's operational needs we can buy the PAK-FA (or another aircraft if acceptable) off the shelf when the need arises. Which is kind of exactly what Doval ji implied. The PAK-FA will probably still fly in IAF colors in limited quantities one day. The FGFA will not.ShauryaT wrote: I do not think anyone would object on the need to invest into our own MIC but we would be conflating two separate objectives.
