Sukhoi Su-57 flight testing and development

Steven said:
The aft fuselage section (housing the electronic warfare equipment) was made longer, and the circumferences of the aft lower fuselage, some doors and hatches, as well as wingtips have been modified. Fifteen first-production aircraft will be made in that configuration.

Is he referring to the circumference of the nacelles? If so, what changed?

Basically this.

I recognize that the nacelle materials changed as it's no longer bare metal like on the first five aircraft. PiBu however refers to a change in the circumference, which would imply that the shape and size (the OML) changed.

What are those inlets at the base of the vertical fins at the 16s mark?

They're for auxiliary and environmental control systems.
 
the 7.23 min in Pt 2 are interesting.

Looks like yes, They want to do 3D TVC with completely gimballed nozzle.
 
The speaker says what all footage is a 117s(su-35) engine.
Both 117(stage 1) and 30(stage 2) are under veil of secrecy.

o rly? who told you that BS? because they do show both 117 and 30 in episode and presenter never says something like this
 
Steven said:
That would entail a considerable amount of additional flight testing.

Well it's just natural and that just mean Su-57 can have multiple engine stages during its lifetime.

At 20:15, is the model on the far left on top of the console what I think it is? Cheeky Russians.

There are a mix of a few sukhoi and mig models there. Zerohedge claimed its a 6th gen Russian hypersonic fighter (which seems ridiculous). The wing sweep angle looks around 40 deg and fuselage looks transonic not hypersonic.

If the scale is the same for all models, it is half the size of the others. I am hoping its their next generation Mig Lightweight fighter.
Would like to see a closer look at it. Not necessarily a testor Ferret?

Lol. Funny part on 29:04 of that video: long known fake shot on launching missile from internal bay. Yeah, quality as usual...

Reminds me of the BAe P.125 ASTOVL concept from that angle.

Hmm... there is also a five sided object on the tail... maybe a Russian version of the Supersonic Bidirectional Flying Wing?? ;)

Probably nuclear powered stealth VTOL bomber. Will resemble UFO until spotted, after that will make "KIROV REPORTING" sound...
 
Wish there is more about maturity of the N036/Sh-121 sets. I wonder if they will use more modern module with larger transmit power.

. Switching to tiled module however seems unlikely as that may involve more work in terms of coolings and possibly need to compensate change of weight.

- How is the work on the Su-57 program? Does this plane have prospects in India?

- During the Army-2018 forum, we signed two contracts with the Ministry of Defense for the manufacture and supply of fifth-generation Su-57 multi-function fighter jets and MiG-35 multi-purpose aviation complexes. The first production aircraft Su-57 will enter the VKS this year. Representatives of the Ministry of Defense of Russia stressed then that the VKS in the near future plans to receive 15 serial machines. At the end of last year, flight tests of the Su-57 with the engine of the second stage began in Zhukovsky.

We have repeatedly said that we are open to working with India on this program. India is traditionally Russia's largest partner in the aircraft industry. This applies both to the supply of various types of Russian equipment to the Indian market, and joint production programs. Within the framework of the Make in India format, our Indian colleagues consistently develop the industrial potential of key sectors of the economy, including aircraft construction. This is an important opportunity and a niche for KLA. We know and understand this market well, we have traditionally open and constructive relations with key Indian partners that have been established over the years. I think that the ways of mutually beneficial cooperation and on the fifth generation aircraft will be found.

Should it matter if Izd 30 comes late , With 117 Engine it should still supercruise and the engine disigner has mentioned that 117 has 80 % new components which makes it a new engine in itself.

New engine is good may be it can supercruise better , accelerate bit faster and with reduced stages may be they will have to re-calliberate the CG and FCS since the engine will be shorter due to reduced stages but having dozen of aircraft with 117 engine would be a good start and in winning export contracts.
 
Only a couple of frames in the second contract ("LRIP1" being 2 frames and "LRIP2" being 13) are scheduled to have Izd.30. First frame planned for delivery this year and the second next year. Dunno if they plan to start deliveries from second contract in 2020 too.
 
Viktor Bondarev: no one could surpass the combat capabilities of the Su-57

Виктор Бондарев: боевые возможности Су-57 пока превзойти никто не смог » Авиация России

По его словам, малозаметный, высокоманевренный, высокоскоростной российский истребитель пятого поколения, умеет уходить от атак противника на сверхзвуковой
aviation21.ru aviation21.ru

Chairman of the Federation Council Committee on Defense and Security Viktor Bondarev in an interview with "News»I highly appreciated the technical, flight and combat characteristics of the Su-57 fighter.

According to him, the subtle, highly maneuverable, high-speed Russian fighter of the fifth generation, is able to escape from enemy attacks at supersonic speed without the use of a boost.“Not a single long-range radar detection aircraft is able to detect it, not a single anti-aircraft missile system to shoot down. At the same time, it can hit any targets both on the ground and in the air. On-board electronics helps the pilot to solve several tasks at the same time, to conduct an all-perspective battle with missiles of different range of destruction. The combat capabilities of this aircraft at this stage of industrial development could not be surpassed by anyone, ”said the chairman of the committee of the Federation Council.

He added that on board the Su-57 you can place the most modern precision weapons. Moreover, the current range of combat equipment is not finite. There are great opportunities for modernization, for development, Bondarev concluded.

As for the price, the senator admitted that, although it may be somewhat high, it fully justifies itself.

“We see the fate of countries that have saved on national defense and security. And even if some of them managed to preserve their sovereignty, like Syria, it is difficult to even imagine what fabulous money they have to spend now on rebuilding the country. Much larger than those that they
would have invested in equipping the army with better weapons, ”concluded the senator.

I think what's gonna keep Western planners up at night in the future will be less about the aircraft itself but the weapons it's able to carry and deploy
