Sukhoi PAK FA

[akshay m]

@akshay m why do you think there should be a change in the inlet. I have heard of difficulty in pressure recovery in some cases for such shielded inlets as the T-50 currently has. But then would that disability still be as damning with 3-axis-post-stall-maneuvering capability that T-50 and PAKFA bring to the table. OTOH what if putting those inlets up front, on T-50 kind of plane with so much skin, throws up some drag issues. Unless off course you are ok to let that happen for some other reasonable trade-off.

stealth , stealth,
the engines inlets placed below , the fuselage compromises her stealth, apparently, according to some

and besides the Phase 1 version doesn't have S shaped inlets
even though shukhoi submitted a patent for it.

you can see the engine blades through the inlets in this pic

the aircraft has structural issues too 01 is down because of that.

i am told that they have abondoned carbon fibre composites in some places and gone backto titanium.


anyway it will be the Phase2 proramme that matters most.

it will beT50-9 that will come with all the bells and whistles
IZD30, RAM coating, Active cancellation, aesa, bubble canopy, suprcruise etc,
and in all likelyhood will be the father of the FGFA.

Fifth gen fighters on HAL Ozar’s anvil

NASHIK: The Hindustan Aeronautics Ltd (HAL) may use its Ozar facility to manufacture fifth generation fighter aircraft, for which it is already in talks with Russia for co-design and production. T Suvarna Raju, chairman and managing director, HAL said, "We are co-developing the fifth generation fighter aircraft (FGFAs) . We have completed the first phase and are in talks with Russia for detailed design and manufacturing of the aircraft. We are planning to manufacture the FGFA at our Ozar facility." Raju was speaking to media persons during a visit to Ozar for attending a conference of airline operators on Saturday. He added, "We have also decided to manufacture the light combat aircraft (LCA) Tejas at large numbers at the Bangalore division of the company." The ministry of defence had announced on Friday that, "India signed the inter-government agreement with Russia for co- development and co-production of fifth generation fighter aircraft in October 2007. As per the agreement, the Hindustan Aeronautics Limited (HAL) is the designated implementation organisation from the Indian side. The HAL is supported the by the Defence Research Development Organisation, the Council for Scientific and Industrial Research and other agencies." The statement added, "The HAL and the Rosoboronexport of Russia have signed the general contract in December 2008 and the preliminary design contract in December 2010. The preliminary stage of the project has been completed in June 2013. The next stage of development would commence upon signing of the research and development contract."

Here is the picture of the F-18 engine radar blocker

You can actually see the Inlet Guide Vanes behind the blocker.

Now given that an AL-31FP on which the currently installed engine of T-50 is based, actually has about 2400+ blades distributed among its 13 stage Compressor (rotor+stator both and high presssure + low pressure both). How many blades should you hope to count in a real Inlet Guide Vane and how many do you count in the picture attached in your post. Mind you, you are seeing only about 1/4th of the engine face.

F-22 too had a lot of Titanium and I think T-50 itself has more CFC in it than the uber raptor which I concede is the gold standard in Fifth gen stealth. Most times titanium etc usage has more to do with availability of spare machining capacity vs. spare autoclave capacity.

I rest my case.

T-50 PAK FA 5th Generation Jet Fighter’s Main Secret Revealed

Despite a number of technical details and specs about the Russian Sukhoi PAK FA (also known as the T-50) fighter jet being known to the general public, the main mystery surrounding the newest aircraft still remains to be unraveled.

It is with respect to what weapons the stealth fighter will carry.

In an exclusive interview with the Russian TV channel Zvezda, Radik Bariev, head of the Chkalov Flight-Test Center of the Defense Ministry, spilled the beans on the PAK FA’s weaponry.

While the regular Su-35 jet fighter has 12 mounting locations for bombs and missiles, the body of the T-50 – at first sight – has none.

"It does have weapons. Let people dream a bit and use their fantasy. It also has locations for mounting weapons. It has everything it needs, and even more," Bariev told Zvezda.

According to the Russian military, the weaponry is one of the most outstanding features of the newest aircraft, and thus it is still kept a secret.

The single-seat, twin-engine jet fighter — the first operational aircraft in Russian service to use stealth technology — is designed to be used to achieve air superiority and assist in ground attacks.

Besides its ability to fly at speeds well above Mach 2, the T-50 boasts other, even more important, features such as invisibility to radar, powerful weapons and high maneuverability.

The use of composite materials, innovative technologies, advanced avionics and engines ensure the T-50’s extremely low level of radar, optical and infrared visibility.

The T-50 also carries the upgraded BINS-SP2M inertial navigation system, that autonomously processes navigation and flight information, determines position and motion parameters in the absence of satellite navigation, and can integrate with GLONASS, Russia’s space-based satellite navigation system.

In December 2014, Russia’s United Aircraft Corporation announced that production of the fighter was ready to begin in 2016. Fifty-five PAK FA jets will be delivered to the Russian Air Force by 2020.

Real killer app, would be the day they mate the hypersonic Brahmos onto that thing.

Even If Russian Don't India surely will be going for it.
Su is ready with Brahmos so there is no point in keeping Brahmos away from FGFA T-50 wat ever you can call it.

IAF halves its demand for Russian fighter jets

Looking to cut costs and prune military imports, the Indian Air Force (IAF) has halved its demand for Russian-built fifth generation fighter aircraft (FGFA).

It now wants just three squadrons of the fighter jets which are to be inducted into the Russian Air Force in 2016.

Sources say the IAF has scaled down its needs and now indicated that just three squadrons (around 18 planes in each), besides a few more for training of the pilots, will be enough for now. This works out to be 65 planes, almost half from the earlier projection of 127 FGFAs to be jointly designed and produced by India and Russia.

The T-50 has been built for the Russians under the PAK-FA (Prospective Airborne Complex of Frontline Aviation) programme for the fifth generation fighter aircraft.

A plane will cost $100 million (Rs 650 crore). Three squadrons are the projection of an off-the-shelf deal India is pressing its military ally for immediate delivery of the planes.

New Delhi has suggested to Moscow that the T-50 fighter jet can be supplied to the IAF, while the research to improve upon the aircraft can carry on simultaneously. The Tribune had first reported about India’s offer on February 24 this year.

Simultaneously, the IAF is also working on a $11 billion R&D contract for long-term development of the jet. It is pending ratification since 2013. In a written reply to the Rajya Sabha on August 4, Defence Minister Manohar Parrikar said the preliminary design stage of the fifth generation fighter aircraft programme completed in June 2013.

“The expenditure incurred so far is Rs 1,483.15 crore,” Parrikar said. The next stage of development of the fifth generation fighter aircraft will commence after signing of the R&D contract.

The problem is in case India opts for the R&D contract route, the deliveries are envisaged to commence 94 months – eight years. The next best option is to go for an immediate off-the-shelf purchase and in case the research-and-development contract works out, more jets can be produced here.

With a dwindling fleet of fighter jets, this wait is not an option for the IAF, said sources. By the end of this year, the IAF would be at its lowest combat strength in more than a decade. It will be down to 32 squadrons by the end of this year and in the middle of a predicted shortage.

In a nutshell, the IAF with 576 fighter jets will be well short of the 750-strong fighter jet fleet mandated by a government sanction to wage a simultaneous two-front war with Pakistan and China.

The pruning down of numbers has been done as the IAF is backing its own options of getting French-origin Rafale jets and the remaining batch of 72 Sukhoi-30 MKI jets from Russia, sources say.

Prime Minister Narendra Modi during his visit to France in April this year announced the intent to get 36 Rafale jets. A cost negotiation committee is in talks with the French company and the numbers could go beyond the announced 36 as the IAF has projected a demand for 80 Rafale-type planes.

There is no attributed source on this. So to that extent remains doubtful. But I think people in IAF would not be above this either. Heh heh, these IAF guys are really something. They have already attacked FGFA (which is not even made yet) by citing deficiencies that these experts/professionals have noticed in PAKFA. That too in semi-official seminars. Lame guys.

Just to have the budget manipulated they will do whatever their Dassault masters suggest.

Anyway the R&D is a real national capability and absolutely all of the FGFA-R&D effort till now has been done in UPA regime. If people like UPA had been supportive then hardly a chance of the NDA guys holding back on the FGFA.

From the low end the LCA Mk-2 will help the AMCA effort and from the higher end the FGFA understanding will help also. I just hope we are able to get the maximum possible workshare in the FGFA. Without workshare FGFA is only marginally better than F-35 JSF, in that both would be imports and while one will have better kinematics the other will have better sensors for sure. Hardly a choice.

@Pulkit I was concerned about the Hypersonic Brahmos. Since it is still not prototyped so we don't know what weight category it will turn out to be or if the weight has to be kept down while also decreasing the ranges possible. Too much is still unknown on Hypersonic Brahmos. The stock Brahmos would off course be there on FGFA.

 

[Punya Pratap]

My two penny worth opinion :

The IAF is trying to do a Su 30 MKI repeat on FGFA where they will go for 56 PAKFA and then give their inputs to Sukhoi/HAL to tweek it and et-voila... you'll have a MKIéd PAKFA or FGFA in our parlance!!

I think there would be a return clause somewhere in there so that we can return the T-50 / PAKFA to the Russians the same way we returned the Su-30 M/Mk.

Bearing the above in mind I have objections to the title of the above article.... IAF has not halved the FGFA order but just ordered 56 T-50's to test and get a feel off so that they can lay down the essentials for FGFA!! SMART MOVE I SAY AND STUPID CAPTION OF THE TITLE!!

Somehow these so called Journalists and some elements in the IAF keep saying they have only 576 Fighter Jets. Though from my calculations, the Total strength of the IAF is about 700 .
Furthurmore it would not fall any short of that as 3 Aircrafts..i.e more Su-30MKIs , HAL Tejas and 36 Rafales are being simultaneously inducted till 2020.
Can someone clarify that?
