published photos resume flights after a major refurbishment of the fifth-year experienced obratsa promising fifth-generation fighter PAK FA - T-50-5 aircraft (tail number "055"), gets renovated designation T-50-5R.

The article by Olga Shcherbakova in this resource states that "Another PAK FA started flights in the sky over the Komsomolsk-on-Amur. One of the three fifth-generation fighter T-50, which should have this year to connect to the flight tests already takes participate. This PAK FA being flown may have seen residents of the Leninsky district - a fighter for more than two weeks of flying either alone or accompanied by Su-30 ".:


Our blog has already reported that the plane T-50-5R made its first flight after manufactured at the Komsomolsk-on-Amur aircraft plant named after Yuri Gagarin (branch of JSC "Company" Sukhoi ") overhaul and refurbishment of 16 October 2015.

Overall, T-50-5 aircraft, built on KnAAZ (KnAAPO), made its maiden flight in Komsomolsk-on-Amur, October 27, 2013, and 18-20 November 2013 self-flew to the airfield of "Flight Research Institute named after M. Gromov "in Zhukovsky, where he joined the test program PAK FA.

However, the June 10, 2014 T-50-5 aircraft was seriously damaged by fire in the right engine while landing during a demonstration flight in Zhukovsky before the Indian delegation. The plane was sent for repair to KnAAZ, which took more than a year. Get a new designation of T-50-5R aircraft was rebuilt using the airframe suspended construction on KnAAZ flight prototype T-50-6 (the last was built to replace non-flying prototype of the T-1.6.50 and flight prototype T-50 6-2 - the first flight of the latter, according to unofficial information, it is planned in Komsomolsk-on-Amur in December).

In addition, it is possible, before the end of December 2015 in Komsomolsk-on-Amur will be raised in the air is another prototype of the PAK FA, designated T-50-8

So your livejournal reports a first flight of T-50-5R on October 16, and the 27th?? I would imagine the roll-out and taxi-tests beginning the 16th, and the actual first flight on 10-27-15?? you would concur that is what they are saying?? or no??

Anyway, they did take the fuse of 6-1 in order to rebuild 055 just as I predicted they would, did they not? No doubt a lot of hard work, but yes they did rebuild it, kudos to Sukhoi!

up to my understanding it flew on the 27th and used T-50-6 parts, it is the same bort 055 aircraft, it just took parts of T-50-6

Is the text really so unclear ??

It had its original first maiden flight on 27 October 2013 ... was transferred to the "Gromov Flight Research Institute" at Zhukovsky on 18-20 November 2013 and sadly had its mishap on June 10, 2014.

After being rebuild it now had its second maiden flight on 16 October 2015.

So nearly exactly 2 years after its first flight ....

By the way IMO even if indeed still the old '055' it is more than the old airframe + a merely "parts of T-50-6", it's a complete rebuild and I wouldn't be surprised if at least a complete center-fuselage is in fact '056'. So percentage-wise I expect it more a T50-6R than a true T50-5R, but that's most likely an academic question.

well if i am honest, the original news source does not say it is 055, this is what it says

One of the three fifth-generation fighter T-50, which should have this year to join to the flight tests, is already taking part in them. This PAK FA being flown may have seen residents of the Leninsky district - a fighter for more than two weeks of flying either alone or accompanied by Su-30.
According to the United Aircraft Corporation, two more T-50 flight tests to join later. On Tuesday he told President Yuri Slusar KLA. He noted that three flight samples would "intensify the flight test program."
- It includes a huge number of flights, so the more we will be "on the wing" of experienced aircraft participating in the flight test, the faster the program will be implemented. The program goes to the chart. We reaffirm the characteristics that initially when placing TK in the car were laid and satisfied with the progress of the program, - the head of the KLA.

it is possible it is T-50-6

I was in fact a little confused as I misunderstood Oct 27, to be 2015, when the article does clearly state Oct 27, 2013 for its first flight.

You had noted the extensive damage, and as I predicted shortly after the accident, they did take the next center fuse off the line, and reuse wings, tail, landing gear, possibly even forward and aft fuse as most of the fire damage was indeed in the center fuselage. I was employed for a time in an aircraft service and repair facility, we worked on aluminum aircraft mostly, but on occasion a glass-fibre bird would show up??

The glass fibre is incredibly difficult to repair, and carbon fibre is even more difficult, but irregardless fire destroys them all and renders them, "unairworthy".
Their strength is dependant on the clean bond of carbon fibre fabric and the bonding agent, in fact carbon fibre is bonded in a heated, air-evacuated oven. The part is created in a mold, and fibre and bonding agent formed in as close to the finished part as possible, then prepped and finished to form the finished part, which may then be bonded or joined to additional pieces to arrive at the finished product.

Ok ... but T50-6 is unlikely since - at least from what I know - there are "few" 6. The first one T50-6-1 is now re-used in 055 and was once planned to be the final stage 01 prototype and there is reportedly a second one T50-6-2, which was originally planned to be the first stage 02 and Indian prototype. However I must admit I really do no longer understand all this ....

from azokh wei

Improvements cover the gun, and the fuselage. Panels of RMB under the threat of separation, so they will increase 2-meter plates.
T-2.6.50 - to perfect systems on FOX
T-50-8 - docked SUNGLASSES, as planned transfer to LIS 15.10.
T-50-9 - began docking of the fuselage.

T-50-2 - completed maintenance work, stabilizers (GO) replaced by new, replaced the left engine.
T-50-3 - installed a new set of 101KS-B, SIC patched receiver under the regime of refueling in the air.
The total plaque exceeded 1000 hours.
T -50-8 - term transfer to LIS shifted to 01.11.

Long-term plan for the T-50 to 2020 .:
2016 - T-50-9 and T-50-10 and T-50-11.
2017 - T-50-12 (re-static), the T-50C-1.2 .
2018 - T-50C-3.4
2019 - T-50C-5,6,7,8, MIT 1.2.
2020 - T-50C-9,10,11,12, MIT 3.4.
In articles T-50C and the MIT design documentation for the plant not yet been received.

Well, let's say, there is no "standard" 2nd stage does not exist. The design is being constantly improved, every day makes a difference. 50-8 unlike 2.6.50 should get a full set of avionics (radar L-band, a complete set of A-402, etc.), but strong differences in the structure does not. 50-9 from 50-8 differs mainly in the direction of improving manufacturability. T-50-7 on the fuselage corresponds to 6-2 on SUNGLASSES be even more advanced (redesigned side members in order to increase strength).

 

[Air Force Brat]

Exactly, and as we see Aksha's list we should see 07 and 08 delivered to flight test, 052 has returned to flight, fuel leaks fixed as well as Horizontal Stabs replaced??? hummmm, and left engine replaced? to be expected, but the horizontal stabs???

and T-50-7, I'm supposing 07 will receive further structural upgrades?? to the side members?? so could be fuse structure??? wing attach?? or even weapons bay structural upgrade, leaves a lot to the imagination?? or interpretation???
