2. Concerning the problem with Russian “sources”





3. Concerning T50-5:



Again, I am correct and given my sources all agree on that. No. 055 is dead, it died a painful death on the runway on that tragic day long, long ago. Period and that can’t be denied.

The other side – and now it’s the old question like “is the glass of wine is half-full or half-empty?” – is that UAC/Sukhoi very much understandable was not willing to accept this loss as a loss. They decided to use whatever parts reusable and to mate them on a new airframe (in fact no. T50-6-1) …. If this was done to hide the loss, to make the best out of this crash by showing the ability to rebuild and repair such a sophisticated aircraft and to gain additional expertise ??? I don’t know and most likely it is a mix of all reasons.

However – and here come’s Your question – all You ask, all, who have experience in aircraft design, material strength and damage repair … all reliable members in certain forums be they pro-Russia or against … ALL tell You that after such an accident the major structure of this particular aircraft, all load and stress-bearing structures made of metal and even more composites are damaged beyond repair. Period.

As such all Sukhoi was left to do – and that’s again being confirmed – they used the partially completed airframe of T50-6-1 and added all was left usable from T50-5. But honestly that could not be the center section, that could not be the engine compartment and engines … also not the wings, since these are an integral part for the center section due to stress and load bearings … so what remains to be taken over ? At least not much and surely a minor percentage in comparison to T50-6-1.

So who is right ? If You think it is in fact a “repaired 055” regardless if it now features the complete center-fuselage + wing section of T50-6-1, then You are correct … but for me it is de facto nothing more than no. 056 finished with a few parts cannibalized from no. 055 and the old bort number ‘055’ added.


All the best,
Deino
I know most of what you said, so i will make it short and we can forget about it, and leave if other people want to join and have a different points of view.

Any way i will be very busy next weeks and i will only post if new pictures appear or even better the new prototypes appear.

As probably you have noticed, i have followed forums like KEY aviation LTD, which i only follow for PAKFA, i know about all the small pieces added, most of them are sensors and a few parts that were claimed were part of the supposedly fuselage weakness by posters there.

To start let us say you are playing the conspiracy theory, why? Sukhoi and AUC have not said any thing supporting what you are claiming.

But let us suppose it is the case, the the accident has no official cause, only a fire suddenly happened, some people say it was the engine.

The supposedly 06-1 fuselage was never claimed by Sukhoi, UAC or Rostec, leaving it as a conspiracy theory of LTD forum key and perhaps a few Russian websites.

The supposedly re-enforcement has not seen any fuselage change, if you look at the prototypes all remained the same except for the long sting featured by 01.

The shape of the aircraft has remained basically the same, Sukhoi claims the flight test is okay, you are claiming they are in trouble.

The only part of the structure which potentially could be weak is the weapons bay, aircraft like the C-5 need a strong back to allow to open the rear door open during flight.

PAKFA could have that trouble, maybe, who knows.

About the lack of new prototypes, well you could say the aircraft is in trouble, but i think they have more financial troubles.

So i will tell you the difference between your view and mine, i consider conspiracy theories about PAKFA as unreliable as you consider official sources.

So while i do not deny Sukhoi can hide things, i do not think conspiracy theories are 100% true, specially if they come from Forums which have nil access to the project technically speaking, and i mean Sukhoi engineers are not going to be posting in forums secrets, only fans post in forums because basically we have no access to PAKFA, we only post for such reason

Dear b787

… I think You are mixing a few things and that adds much to this overall strange situation.

As such let me set a few things straight.

1. Concerning SDV in comparison to other forums:



In general You might be correct, but not at all: Key has a fan forum for enthusiasts and IMO most of them are either young, very much enthusiastic and often blinded by prejudice, nationalism or simply since they don’t know better. As such, the tone is often rude, dominated by ignorance and again the result that many honorable members don’t want to be bashed by these trolls; a situation that is not eased by the more or less “nothing-doing” moderators.

Here the percentage of professionals or educated ones is much higher, we have certain members with an – IMO at least – higher education, the ability and will to learn, do argue and discuss and probably even to review their own opinion. Again that is assisted by a much more stringent team of moderators …

2. Concerning the problem with Russian “sources”



Sorry to say so, but the situation is similar to the Chinese one: There are only few official confirmed information and the number of “sources” in different forums is probably much more confusing.

As such one has to carefully read between the lines, read a lot and has to compare who said what, when and even more did it come true !? In mind of these Chinese “sources” this is only possible if You are an active member in several groups, if You are willing to learn and listen carefully … and only then after that long, long time You are probably able to identify and differ the “more often reliable” ones from the “fan boys” and / or even trolls.

Concerning Russia the problem is even more complicated since there is an active, politically baked media around, closely connected to the industry and military and the least thing they want is 1. To tell the true secrets (due to the secret nature of these programs and 2. To let them look “weak” to the media, the West and most of all the always-chest-bumping-crowd.

As such, to think all they tell, simply since they are closer to … is plain naïve, stupid or to say mildly, exactly what they want to achieve … and so we are soon up to the main issue: no. 055

Final point: Russian media …. I’m sure Andrei Fomin is fine and even if I rate Piotr Butowski much higher especially due to his direct access to all Russian industrial complexes and the truly important persons, I would be very, very careful to call TV Zvesda or Channel one Russia or Prawda or RIAN or whatever a reliable source. They are in fact all state-controlled or linked, they all have a political ambition as explained above … but if You believe them … o.k.

3. Concerning T50-5:



Again, I am correct and given my sources all agree on that. No. 055 is dead, it died a painful death on the runway on that tragic day long, long ago. Period and that can’t be denied.

The other side – and now it’s the old question like “is the glass of wine is half-full or half-empty?” – is that UAC/Sukhoi very much understandable was not willing to accept this loss as a loss. They decided to use whatever parts reusable and to mate them on a new airframe (in fact no. T50-6-1) …. If this was done to hide the loss, to make the best out of this crash by showing the ability to rebuild and repair such a sophisticated aircraft and to gain additional expertise ??? I don’t know and most likely it is a mix of all reasons.

However – and here come’s Your question – all You ask, all, who have experience in aircraft design, material strength and damage repair … all reliable members in certain forums be they pro-Russia or against … ALL tell You that after such an accident the major structure of this particular aircraft, all load and stress-bearing structures made of metal and even more composites are damaged beyond repair.

4. Concerning T50 in general….



You are funny … above You say it is sooooo much secret that nothing comes out and now Your want a source from me. What about logic, what about reading, listening and learning from what others – and here surely not me – are telling and deducting from images, a deep observation of the development and timeline especially in comparison to the original scheduled and promised events … several of them did not came true even today.

Just simply look at the images at different dates of the individual prototypes, look, when they flew, when additions were noticed – like additional stripes of materials to improve stiffness or strength on the wings, the tails and so on ?? Look, when additional prototypes flew which later gained similar add-ons ---- surely only for cosmetic reasons.

And if You then put all this in contex of reports from Piotr about strength issues, that the airframe had to be modified … even the next prototype T50-6-2 – the first of batch 02 – will be so much different structurally to the batch 01 aircraft so far that they are de facto comparable to the revised J-20 ‘201x’ prototypes developed after the tests of the ‘200x’ types.

If everything would be fine, if there were no issues … why then such a long break in flight testing or the appearance of new prototypes ? I do not want to open a new can of worms now, but for the J-20 in comparison some are already hinting problems if not a new aircraft is seen within half a year … and for the J-20 we know surely even less … so what here on the T50 ?

Did You ever looked back how often any of Your beloved and trusted media-members, military or UAC/Sukhoi officials promised that the T50 will be in service already, will be mass-produced from date xxxx on … will be purchased in large numbers, wil,l have super-duper-hyper modern missiles, will also feature a super-duper radar, avionics, and propulsion system much, much, much, much more advanced than anything else be it operational or under test … and what all of these promises became true or if, when did they become fact?

Don’t get me wrong, I do not want to bash the Russian aviation industry, Sukhoi and especially not the T50. It is a fine design, a remarkable type with certain technical solutions worth to be more than proud …. But if some Russians – including the manufacture – wants to play with the “big guys”, they must accept to be measured by or against the current yard-stick and that’s the F-22; an aircraft already in service since 11 years. So IMO the T50 should be treated and judged rather by a rational and not emotional standpoint and from this it still has a long way ahead to be comparable with the “big guys”.

As such – even if You might deep me arrogant – You surely can pots whatever You want, but to be taken seriously You should look not to be a UAC-PR-spokesman but a valuable member of this forum…

All the best,
Deino

Thank you Deino, for a very succinct and well thought post, with that you have spoken well for those of us who take pride in our labor of love, whose passion happens to be accuracy and honesty, and for you yourself, the kindness and patience you continue to show toward your fellow posters and moderators honors the tradition of BD, Jeff Head, Webby, and our worthy forerunners! most excellent work, and very clear and to the point!

@Deino Just wanted to ask what is SDV ;)

Now can you guys stop this discussion. i am tired of reading it. Give it a break guys.


Sorry, ... only a small typo ! I meant SDF.

However should we stop ? It's probably the first time since pages that this "discussion tread" gets a true discussion and not only a "Russian-media hyped news post collection" !

But You are correct ... I leave it.

This is a forum Ali, about the PAK-FA and its development, flight test, and eventual production? (Russia has limited its initial buy to 12, after extensive redesign structurally of the proto-type). If it does not interest you, there are many, many, more threads that you might enjoy, feel free to left click off this thread and onto something more to your liking??

Oh, and you are off topic, remember it is a "forum", where the big boys get together to discuss the serious elements of life. Feel free to hang around if you have anything of a substantive nature to add to the PAK-FA/T-50 discussion.

Thanks, Brat

Correct me if I am wrong, but wasn't 6-2 supposed to first flight in Jan or Feb???

Courtesy of Jura, sometime late last year on the possible debut dates.

I looked at the last two pages here, noticed both sides pushed it hard LOL ... what I'll do now is to quickly translate (to the extent I can understand aircraft development :) which I can't) what I found on
Please, Log in or Register to view URLs content!
in a post dated December 14; it concerns some 2016 schedules:
  • Т-50-8 finishing the assembly, reworking the fuel system, transferring to FTS 20.01.2016, flutter tests 27.01.-01.02.2016, coating 25.02.-25.03.2016, the first flight 15.04.2016, delivery 22.04.2016.
  • Т-50-9 putting detachable wing parts on 10.02.2016, engines 10.03.2016, transferring to FTS 20.03.2016.
  • Т-50-10 until 15.01.2016 obtaining fuselage parts, fuselage docks, transferring for final assembly, putting detachable wing parts on 01.03.2016, transferring to FTS 30.03.2016.
  • Т-50-11 obtaining the center section, fuselage, transferring for final assembly until 01.03.2016, putting detachable wing parts on 10.04.2016, coating 15.05.2016.
It could be interesting to see later in the coming year what actually happened, as I found this schedule (or hoax!?) reposted in Russian Internet while looking for fresh PAKFA news.

@Air Force Brat There is an old saying Brat..... Jagay huay ko nahi jaga saktay.... Translation.... You cant wake up a person who is already awake....

In the end after reading all the zero sum discussions, which by the way reached no conclusion, it was a waste of time.

I also come here to get enlightened BTW :)

I think we have reached a very fine conclusion Ali, as Master Deino has very succinctly "corrected" several inaccuracies with a "true discussion"! that you have summed up this masterful and polite correction as "zero sum"? leads me to believe that you sir, have been caught "sleeping in class". Heh! Heh! Heh!

Forums are clubs, if you go to VK .ru they had a poll where they asked, which is the best fifth generation fighter, since the forum is Russian , 80% of the voters answered PAKFA.

Ask the same poll here and you will find different results, if you go to F-16.net, you will find F-22 will be the winner.

So if i post this picture, each forum will have a different reaction, so in a forum, in my opinion the ethnicity plays a very important part in the opinion, and that is typical because in forums like this, people let their national feelings run free, i can assure this CG picture will create different emotions depending upon the person
