Sukhoi PAK-FA (T-50, I-21)

[medal64]

Did somebody really leaked the PAK-FA drawings flateric.I hope you can get and send us this drawings as early as possible?

[flateric]

Very funny...do you have a sense of humor?

[medal64]

Yes but i couldn't understand what you mean very well.For this reason I asked this question but now I understood

[medal64]

What do you think.Does three prototypes enough for creating a 5th generation aircraft(PAK-FA)?.And how many prototypes had used for su-27 or mig-29.Do you have any information?

[flateric]

it doesn't say if it's a military or civil plane ihmo it's a civil.

But it says "The Russian Federation defense ministry and Rosoboronehksport [state arms export company] will be customers"...

Perhaps its the new MiG-35?

Mig-35 plans at Sokol confirmed.

Aviation Plant Sokol will make MiG-35s
08:19, 04 February 2008

OAO Nizhny Novgorod Aviation Plant Sokol (United Aircraft Manufacturing Corporation company) is preparing for production of the new MiG-35, developed by RSK MiG.

The plane is scheduled to put on the market at the turn of 2009-2010. At the end of 2008, Sokol plans to begin serial production of Yak-130 aircraft to order the Defense Ministry. It is reported to IF-Region with reference to the aircraft factory Director General Mikhail Shybayev.

Were two of each type prototypes of ATF designs enough? So you can anser your questions yourself. Regarding Su-27 and Mig-29, there are wealth of info on the net.

I don't know how many prototypes used for su-27 or mig-29.I wanted to learn.At some forums there are talks about three prototypes are not enough for PAK-FA but I don't think so.For this reason I asked this question.At forums talks are about;USA used 9+ prototypes for F-15,France and Sweden used 5 prototypes for Rafale and Gripen.I wanted to learn generally in Russia does companies use less prototypes for the development.

Sukhoi T-10 - 12 prototypes (T-10-1 to T-10-12)

Sukhoi T-10C (Su-27) prototypes and Test & Evaluation aircrafts

T-10C-1 (ex. T-10-7)- lost in 1981, pilot ejected
T-10C-0 (ex. T-10-8)  - static tests
T-10C-2 (ex. T-10-12) - lost in 1981, pilot killed

Т-10-15 (future P-42)
Т-10-16
Т-10-17 almost lost in 1983, landed with half of wing console and vertical tail destroyed
Т-10-18
Т-10-20
Т-10-21
Т-10-22
Т-10-23
Т-10-24
Т-10-25
Т-10-26
Т-10-27

To avoid confusion, the Kyrillic 'C' must be read as Latin 'S' (T-10S ...). Sometimes it's written without a dash (T10S). Forgive me, Flateric  .

There is a difference between demonstration aircraft and real test vehicles. The two YF-22/YF-23 could be seen as first prototypes, but they were essentially demonstration aircraft. Later 9 series prototypes has been built, complemented by 18 or so PRTVs (instrumented production aircraft).

[medal64]

And I wonder that in the near future will Ruaf get mig-35 and su-35BM without PAK-FA or will Rusaf use this aircrafts as competitor of the F-35.I mean for not to spend too much money PAK-FA will these aircrafts be the cheap F-35 competitors.

I think that we can agree that what will fly in 2009 (or 2010) will be truly *demonstrator*. While YF-22 and YF-23 flew with at least actual engine prototypes, T-50 will make maiden flight with Article 117C, which no way engine that airfame was intended for.

MiG-35 and Su-35 were designed and built with the export as the main goal.

Whan creating a 5th generation aircraft its sure that you must have the latest technologies for producing the aircraft parts and for calculating the parts specifications.Does supercomputers have a big role at creating an aircraft.Does sukhoi or Mig have supercomputers.Almost I know boeing and lockheed martin have supercomputers.What is the role of supercomputers at aircaft industry.

medal 64,
of course they have access to supercomputers....  in fact they apparently have atleast two IBM supercomputers ( blue gene no less) that they acquired earlier     ... seriously Russia today has plenty of access to computing tech from the west and has also developed its own stuff. . Also, Please do not forget that no matter how much some westerners may disparage the Indian contribution to this project, we will precisely bring those things to the table that the Russians may be a little behind in. Computing power is fast becoming India's forte and besides govt agencies like C-DAC, Pune and others who have been churning out top end supercomputing  we also have the Tata funded CRL, Pune which recently created the fourth fastest supercomputer in the world. This list  can go on .. but I have posted,  only to give you an idea of the fact that the PAK-FA project will certainly not be hamstrung due to inadequate computing resources, given the Indian involvement. I must also add that given that there is no lack of financial resources either, more  supercomputers can be imported  


fastest of course is meaningless when talking about aerospace modelling .. but again computational fluid dynamics requires some pretty nifty computing power .... moreover flight control laws etc also have to be perfected ..... so computing power is essential .. not to mention the mission computer itself. Of course the mission computer isn't exactly what you may call a super duper computer
