Good Foto.

 

Any chance of seeing that in higher reso?!

 

It's be a good wallpaper!

I wonder what will do all these ultra modern planes of 5th generation (also very expensive) with electronic failure. I mean even jets of 4th gen still have some classic gauges. Of course their main task is combat, but price of each plane saying - "these machines must be returned to base at all costs". And pilot is priceless.

 

Gauges in 5th gen fighters are only good if there's a pilot reading them! Are U sure there's gonna be humans onboard for piloting. I think it's a wishful thinking!

dang, it's large compared to the mig-29 :joystick:

[Vekkinho]

Yes it's somewhat smaller than Su-27...

 

BTW how and when do they plan to transport these planes to Gromov?

[LupinYonder]

I wish there was a translation but I doubt anybody will bother with this amount of text, and yea the mig is small, dainty ;-)

[Krippz]

The design of the T-50 (although not final) is starting to grow on me.

[jerom1992]

BUMP...

 

So any news? Or any new pictures?

[Vekkinho]

Did it make to Gromov institute?!

[sniffer]

8 April - 1st prototype and KNS moved to Zhukovsky. They want to make it flyable to the end of April to make further tests.

 

There're some 'moves' with new 2nd stage engines which would be probably made by Salut company. Well known prototype would have current engines...

[Vekkinho]

Thanks for info!

no more pictures, looks like the last picture cost someone his job.

Double-integration.

Began pooling the assets to create the fifth-generation aircraft engine.

 

The success of the first flight tests of fifth-generation Russian aircraft loaded with a fair amount of optimism domestic expert community on the future of this project. But so far not been solved yet, some key issues related to the final definition of technical persons PAK FA. One of the most important - in what terms and with what result to finalize the second phase of the engine, fully meets all the requirements for turbojet for forward-looking machines. During the exhibition "Engines-2010" became known, some new information characterizing the engine, which flew the plane, but also to shape the future of cooperation development engine of the second phase.

 

At the airfield the Gromov Flight Research Institute. Gromov in Zhukovsky near Moscow on April 8 from Komsomolsk-on-Amur, was taken to the first flying example of the fifth generation fighter. After assembling the aircraft in late April - early May, will begin construction phase of flight tests.

 

Recall the first time, PAK FA rose into the sky in the Acceptance of factory tests on January 29 this year. During this stage the stability and control of machines, the work of its major systems. One of the most important components of these flights was checking the functioning of the new engine. Despite the fact that the engine for the PAK FA scheme repeats the famous AL-31F, it is 80 percent of the new parts. This low-pressure compressor, combustor, turbine, installed at an angle of 30 degrees swivel nozzle, high pressure compressor, a digital automatic control system with elements of distributed parameters and plasma ignition system. As reported in the exhibition "Engines-2010" Chief Designer included in the Saturn SEC them. AM Swinging Yevhen Marchuk, responsible for creating an engine for the PAK FA, while developing the turbojet, a series of measures to improve reliability and increase the resource. This is necessary because the engine is more intense, has a higher temperature.

 

Plasma ignition system - new Russian engine. Until now, all ignition system to increase altitude, the possibility of running at altitude turbojet used oxygen replenishment. She demanded the availability of the entire oxygen system on board and the infrastructure at the airport. When you create a PAK FA has been tasked to ensure oxygen-free starting. Plasma ignition system installed in the main combustion chamber and afterburner. According to Eugene Marchukova, know-how inherent in the very nozzle with a plasma system: it simultaneously with the filing of kerosene is organized by the arc plasma. It is also very serious know-how inherent in the ignition, where the need for a short time give a very high voltage.

 

The digital control system with full responsibility as applied in the domestic aircraft for the first time. Hydraulic machines are the only executive. As pointed out by Yevhen Marchuk, the exception is one standby centrifugal regulator, which allows for total rejection of all the electronics, for example as a result of the impact of a nuclear explosion, to return to base at a reduced mode. Digital ACS is very mobile and flexible. Previously, analog control, change control algorithm engine takes two or three months, now, this operation takes a few minutes, sometimes not even need to stop the turbojet. That is, as noted by General Designer SEC them. AM Swinging, debugging, and debugging engine run much faster. This in turn leads to compression of the timing of testing new aircraft.

 

The engine of the first phase for the PAK FA is built entirely on the traditional scheme. In particular, deprived of such characteristic elements as a flat nozzle, available from a competitor of our car - F-22. However, according to Eugene Marchukova, work in the field of exhaust systems are maintained. At the stage production of technical documentation are the development of a flat nozzle and the reverse.

 

From the viewpoint of gas dynamics of a planar nozzle clear disadvantages because when you create the need to make the transition from a circular section (engine) on the flat. Loss of traction at the same time can be 5-7 per cent. The advantage of only one thing - providing heat invisibility by closing the turbine blades flat. This mode is used is limited: it is switched on for 5-10 minutes to overcome the enemy's air defense system. To solve this problem, such losses are allowed. But the designers of Saturn are trying to minimize the loss of up to 2-3 per cent.

 

These deliverables should be used in the creation of the engine of the fifth generation of the second phase. So far, the most likely candidate for the development of ideology and the layout of the turbojet was considered a "Saturn", which entered the structure of the Joint Engine Corporation. However, on 14 April the appointment of Director General of Federal State Unitary Enterprise "MMPP" Salut "Yuri Eliseev, Deputy General Director of RBC introduces a new touch to the situation over this very important project.

 

On the second day of the exhibition "Engines-2010", April 15 during a press conference Yuri Eliseev reported on what has made "Salute" with the modernization of AL-31F engines and when you create the fifth-generation turbojet.

 

Conditions of the competition to develop the second stage engine for the PAK FA, according to Yuri Eliseev, envisaged construction of two prototypes: "Eniseisk-A" - "Saturn" and "Eniseisk-B" - "Salute". The first stage of the contest, involving the creation of separate parts, was completed in November 2008, the second, during which participants were required to submit demonstrators nodes, finished in June of 2009. "As for the" Salute ", - said director general of the enterprise - that is the conclusion of a commission composed of representatives from the Ministry of Defense, CIAM and CSRI-30 MO, stating that the work is done in full at a level no lower than the world, the results are recommended for use in designing fifth-generation engine. As for "Saturn", they, as far as I know, the second phase has not been completed. By the third phase, the announcement is delayed from the third quarter of last year, KB Salyut created avanproekt fifth generation engine, which according to the conclusion corresponds to the technical task.

 

In a press release on the appointment of RBC Yuri Eliseev deputy director general of the corporation said that the concentration of efforts of the two major domestic aircraft engine structures both in management and in the production plan will solve many problems quickly and efficiently. In particular, we are talking about the project engine for the PAK FA, which has its own work and "Salute", and the company JDC, noted in the message. As stated by Yuri Eliseev, "I have never had any doubts that the engine of the fifth generation can only be created by joint efforts. Funding should go through the JDC. The question is: what KB is an ideologue of the engine, who will assemble it and who will be responsible , personal responsibility, for the result of "a matter of principle. in size should be selected on a competitive basis." Achieved designers Salyut results suggest Yuri Eliseev assume that the lead in creating the fifth generation engine must be exactly led them to the enterprise.

 

Yuri Eliseev said that still does not know what range of tasks in the new place will determine his employer - CEO of RBC Andrei Reus. But according to his own idea in the JDC "Salute", in particular, should take an active part in the revival of enterprises of the Samara bush, which is composed of "SNTK them. ND Kuznetsov, OAO Motorostroitel" and OAO "Samara Design Bureau of Engineering (SKBM). There, according to Yuri Eliseev, there are problems with manufacturing and testing of new parts and assemblies in the "Salute" could help Samarans. In turn, General Director of "Salute" very interested in cooperation on facilities for railway transport. According to him, "they have a pretty good result for a capacity of up to 8 MW, have experience with liquefied gas. This experience we would be very handy."

Yep - finally first flight over Zhukovsky performed...

[Erdem]

I think it looks awesome. A cross between F-22's slickness and Su-27's evil looks :)

[sobek]

I still don't get the approach, in general they trimmed the shape to be stealthy but didn't hide the compressor blades, and the engine nacelles are almost round. I'm no specialist at radar-band reflection characteristics, but wouldn't that negate the benefit of the rest of the airframe being stealthy to a large degree?

[GGTharos]

They are still working on 2D nozzles and other features to finalize stealth, as I understand it.

[topol-m]

It`s clear that in its current shape it`s not as stealthy as F-22 or F-35 but it`s still a prototype. Let`s give it several years of testing no doubt some modifications are needed to reduce the RCS further and from different aspects.

 

They are still working on 2D nozzles and other features to finalize stealth, as I understand it.

 

It will be equipped with 2D nozzles? Didn`t know that. Goodbye 3D TVC...

BTW that gap between the engines can`t it be used for extending the weapon bays an achieving a flat underside?
