what seems to be the stage 2 programme- 056







from berkut

... So, back in 2010, it became clear that a few poorly designed plane. Required operating overload withstand could not cut the rivets on the air intakes, air-to-air heat exchangers for cracked welds, and the fuel in the tank №3 categorically refused consumed completely. To the first safety car came the assigned resource to 300 hours, in August 2011, it delivered on completion (the rest of the gain made in the factory), and started to design the machine of the 2nd stage (by the way, incidentally removed from the keel 50-1 left there wrench key). At the 2nd stage significantly increased the proportion of composites (virtually the entire lining of the RMB has become), but the weight of the airframe due to increased KCC still excessively increased. Then they decided to replace many nodes B95 duralumin and AK-5 on the aluminum-lithium alloy 1461T with a specific weight of almost 20% less. In October 2012, the final decision on the launch of the 2nd stage of production. It was planned 2 cars - T-50-7 and T-50-8. At that time, at different stages of production are 3 cars 1st stage - 4, 5, 6. But just woke up and decided to make a 50-7 statics. And in February, the 13th decided to make the transition model and assign the T-50-6. To avoid confusion, the T-50-6 of the first phase became known as T-1.6.50, and the car of the second phase - T-02.06.50.
However, among the imported parts for T-50 and the US were the honeycomb structures of carbon, widely used in the wing and tail. Our military leadership decided that this is unacceptable and has decided to "importozamestit" and instructed CVTs "Technology" from Obninsk develop domestic cellular materials. By the way, all the other composites for the T-50 is also made in Obninsk. Expectedly, obnintsev provaflili all time. As a result, grief Sagittarius (he is now GK Pak, not Davydenko) in May even suggested removal of plumage from T-50-4 and put on 6-2, modified fairing and drive spindles, but a month ago finally came honeycomb.
Another problematic issue was the alloy 1461. Desperate crackled when mechanical working, then there must be said that the assembly we still conducted on technologies 70s, that is, the assembly units in unit kuvaldometr still very popular. A similar treatment alloy does not bore. As a result, went reconversion of the parts of the 1461 B-95, and sometimes back again in 1461.Chto, of course, led to the indescribable delight everyone, especially prochnistov.
Thus passed the 2013, 2014 and in February 2015 the first was docked 6-2 fuselage ...

Moscow confused as IAF puts fifth-generation fighter on back burner to buy Rafale

The ongoing MAKS 2015 air show in Moscow features an impressive flying display by the Sukhoi T-50, the fifth-generation prototype fighter's first public outing in two years. But even the rousing applause fails to mask the disappointment of Russian officials at the Indian Air Force's (IAF's) foot-dragging in co-developing the T-50 into a "fifth generation fighter aircraft" (FGFA) that the IAF will buy.

Well-informed sources in Moscow say the IAF vice chief has written a letter that effectively blocks the FGFA project. It criticises 27 different aspects of the FGFA, raising questions that must be answered before New Delhi and Moscow put $2.5 billion each into jointly developing the advanced fighter.

Business Standard also learns the IAF has vetoed a Russian offer to co-develop a fifth-generation engine for the FGFA. This is baffling to the Russians, given the Defence R&D Organisation (DRDO) long-standing attempts at joint engine development in order to end India's expensive dependency on foreign vendors for aero engines. An internal DRDO estimation reckons that India will import aero engines worth Rs 3,50,000 crore over the next decade.

After the DRDO failed to develop the Kaveri engine to the level where it could power the indigenous Tejas Light Combat Aircraft (LCA), it strived to persuade French engine-maker, Snecma, to co-develop an engine. But Snecma declined to share key technologies, especially those relating to materials that can withstand the hellish temperatures created in the engine's combustion chamber.

Nor has Washington agreed to share these technologies, even after President Barack Obama agreed during his January visit to New Delhi that a "joint working group" would explore US-India cooperation in engine technology.

DRDO and Hindustan Aeronautics Ltd (HAL) officials say the Russian offer of engine co-development fits well with the FGFA project itself, since the engine will power the same fighter. Currently, the Sukhoi T-50 is powered by the NPO Saturn AL-41F1, which only is a souped-up version of the AL-31FP engine that powers the Sukhoi-30MKI. A brand new, more powerful, engine is needed to let the FGFA supercruise, or fly at supersonic speeds while cruising without an afterburner. This is considered essential for a fifth-generation fighter.

Military aerospace experts worldwide believe that, given Moscow's economic distress, the T-50 project badly needs India's financial partnership to move forward. So far, the Russian Air Force has ordered only one squadron of T-50s.

Sergey Chemezov, who heads Rostec, the powerful Russian high-technology agency, downplays India's delay. "As for the involvement with India, there is a certain delay, though this is not something that we (Russia) can be responsible for. On our end we can fully continue the development of the project as per our commitments," Chemezov told Business Standard.

But even the defence ministry is questioning why the IAF is delaying a project it has earlier championed, and to which India has committed itself with an Indo-Russian inter-governmental agreement (IGA) and the expenditure of about $300 million in a "preliminary design phase". Critics of the IAF allege it is scuttling the long-term benefits of co-developing the FGFA in order to quickly buy the Rafale, preferably in numbers larger than the 36 fighters that the prime minister requested in Paris in April. A defence ministry official says that, in its eagerness to obtain the Rafale, the IAF has deliberately placed holds on every other aircraft procurement, including the FGFA, the Tejas and the plan to extend the Jaguar's service life by fitting it with a new engine.

According to this official, the IAF aims to create the impression of a dangerous shortage of fighters, so that the government buys the Rafale quickly. In another volte-face, the IAF has proposed that the FGFA not be co-developed but limited numbers of the T-50 fighter be built in India.

If implemented, this would take India back to the 1970s and 1980s procurement model, which involved license-producing fighters like the MiG-21 and Jaguar in HAL without Indian involvement in designing or developing the aircraft.

In the 1990s and 2000s this was superseded by another procurement model that was first implemented in the Sukhoi-30MKI. In this, India specified modifications to the baseline Russian fighter, improving the Sukhoi-30 into the Sukhoi-30MKI through advanced avionics and a thrust-vectoring engine. The much-improved fighter continues to be licence-built in HAL Nashik.

However, by accepting the Sukhoi T-50 without improvements, the IAF is reverting to the 1990s.

This would be a volte-face by the IAF. Three years ago, the IAF has specified 40-45 improvements that it deemed essential for the T-50, listing these out in a so-called "Tactical Technical Assignment". This wish list included: 360-degree radar coverage by adding two sideward-looking radars; and more powerful engines;

The design and development needed for meeting the IAF's requirements would constitute India's work share of 25-30 per cent. If the IAF now demands the same fighter as the Russian Air Force, HAL's work share would fall to zero. And the IAF would get a fighter designed for the Russian Air Force.

Are we under dire need of Rafael , so that IAF has to go to such drastic measures ?

What are the tactical advantage we will loose by not having fewer squadron than the said requirement ?

Please , anyone care to explain.

I think IAF has found a SIXTH GENERATION ERR MAYBE SEVENTH GENERATION FIGHTER IN RAFALE. Or maybe the under table developments (BRIBES) are too much to ignore that even national interests are being ignored by these TRAITORS. They oodling for a 4.5 generation fighter at a cost of more than double the cost cost of 5th generation fighters. Either they are incompetent or at best traitors. This definitely amounts to treason. Rafale deal should be called off, heads should be rolled in IAF and government should consider increasing orders for TEJAS and in the meanwhile as a stop gap MIG 35 should be considered at $35 million it's a steal and we can get 189 MIGS well under $10 billion to raise 9 squadorns, which i suppose will give numbers plus added security. Klimov is already offering 3d vector thrusting technology transfer to India and latest klimove RD 33 engine develops 103KN, a little more tweaks and it can be converted into 5th gen engine which can be used for AMCA. but IAF has poor vision and are now clearly acting like traitors.

So any more political maligning ?

There are a lot of bribes yes. And I guess there is someone from present govt involved in the cut too.
Buying more is not the solution but buying smart is important. Rafale is a good plane, but how would it fare against Chinese J-20 or Su-30 MKK? The French feel that Chinese planes are junk, but honestly the Chinese have come with a lot of new developments which are seriously undermined by the western world. Rafale is no match for Su-30 MKK, and when the Chinese get Su-35, thats good bye India.
The only place where Rafale can really be useful and not have very serious opposition is Pakistan. So are we going to buy 36 planes focusing only on Pakistan?

from our KNAAPO insider



I apologize for the inaccurate information about the absence of Flight T-50-3 in the period 06.2014 - 05.2015. The raid on 05/07/2015 understated.This is a mistake (though not mine).
So, the state on 08.10.2015.
T-50-1 - 219 hours and 197 landings.
T-50-2 - 221 hours, 221 planting. 07.24.2015 during the test TLU-50 cargo destroyed one of BGrO. Aircraft renovated.
T-50-3 - 300 hours, 151 of landing. During preflight inspection of the fuel leak was detected in the region of the left air intake. To eliminate the leak was dismantled the engine and / z.Seychas the build renovated.
T-50-4 - 169 hours and 106 landings.
At 6-2 - assembly, testing of systems, stiffness test, nenansenie PSC, Chi in a minimal amount, 1st flight - up to 01.12., then transport in Zhukovsky - frequency test (the full Volume of) flight tests. The next deadline machines - 01/15/2016.

approaching 1000 Flight hours, 909 now, i didn't add 055's flight hours
