Sukhoi PAK FA

[Kunal Biswas]

From this pic it seems that PAK-FA is substantially longer than Mig29. As Mig29 is known to be 17.37m long, some simple interpolation calculation suggests that PAK-FA is about 22m long, about the same length as Su27. This is hardly surprising considering that both aircraft use same lines of engines. This should put to rest claims that PAK-FA is less than 20 m long.

I wonder where someone getting some calculations ? fan boys at Chinese forums ..

These pictures do show that PAK-FA and Su27 have roughly the sme length whereas Su34 is substantially longer. I think it is safe to say to PAK-FA is at least 21 m long excluding pitot tube.

Great. And you measured it with your hawk eyes.

Safe to say what ? where is the information on official site ?

I dont have any figures but from the photos, PAK-FA is larger than Mig-29 and shorter than SU-27..

This happened in 1991 and was announced as a software error because of problems with the clock.
U.S. GAO - Patriot Missile Defense: Software Problem Led to System Failure at Dhahran, Saudi Arabia

The first supposed BM intercept in history is funny. The system detected a Scud and fired SAMs at it. It was a hit and became the first successful interception ever. Best part is there was no Scud. The system simply assumed there was a missile and fired. This was a software error too.

First of all - apologies for the OT necro-reply.

Only the software error does not explain the 1% success rate for Patriots during GW1. There is more to this story.
An interesting and little known fact is that most of the SCUDS fired during GW1 were not actually "SCUDS". They were modified SCUDS with the Iraqi designation of "Al Hussein". These were basically SCUDS cut up and rejoined to create longer ranged missiles. Although this increased the range, there was a problem. When fired, during the re-entry phase, these missiles were not able to handle the heat and stress and the airframe would often disintegrate. When they disintegrated, the largest piece (but junk) would be the fuel tank. The Patriots would go for this piece while the war-head would fall off separate like a dumb bomb.
P.S. - These were created during Iran-Iraq War to hit Tehran because the 300 mile range of the original SCUDS was not enough for hitting Tehran.

PAK-FA / T-50 Impressive Flying Display

WOW FROM : The 100th anniversary of the Russian Airforce - The PAK-FA / T-50 is a proud salute.

https://plus.google.com/u/0/115477337653794596531/posts/ZYRSxjrunWi

Whoa! PAK-FA/T-50 appears to be a seriously maneuverable aircraft.

It's only been just 21/2 years since it first flew so it's unlikely to have cleared its entire design flight envelope, yet it managed to give such an impressive display.

The weather conditions weren't ideal for aerobatics, with a cloudy sky and low level haze, so the pilot couldn't have been giving his best.

Turning performance was very impressive. Note the use of leading edge surfaces during tight turns in the video.

Eventually, the aircraft will have a more powerful engine. Keep that in mind.

Hopefully, it never comes to it, but good luck to any Raptor pilot who misses his BVR shot and is then slow to run.

A nice vid of Pak FA

India and Russia going to sign biggest-ever defence deal worth $ 35 billion

NEW DELHI: India's quest for a futuristic stealth fifth-generation fighter, which will see the country spend around $35 billion over the next 20 years in its biggest-ever defence project, has zoomed into the decisive phase now.

India and Russia are getting all set to ink the full and final design or R&D phase contract for the 5th Gen fighter by this year-end or early-2013, say sources. It will again underline India's firm rejection of the US offer of its Joint Strike Fighter (JSF) or the F-35 'Lightning-II'.

IAF wants to induct over 200 stealth fighters from 2022 onwards, a senior team of Hindustan Aeronautics (HAL) engineers and IAF experts is going to Russia within a fortnight to ensure that the "full documentation and other work" of the earlier preliminary design contract (PDC) has been completed.

During his visit to Moscow last week, IAF chief Air Chief Marshal N A K Browne reviewed the performance of the 5th Gen fighter, called Sukhoi T-50.

While the Indian fighter will primarily be based on the T-50, it will be tweaked to IAF requirements.

India had inked the $295 million PDC with Russia in December, 2010. The R&D contract on the anvil is pegged at $11 billion, with India and Russia chipping in with $5.5 billion each.

"The three Russian T-50 prototypes have flown around 180 sorties till now. HAL's Ozar facility at Nashik will get three prototypes in 2014, 2017 and 2019...they will be flown by IAF test pilots," said a source.

"Russia has already given the draft R&D contract to us. It will include the cost of designing, infrastructure build-up at Ozar, prototype development and flight testing. So, India will have scientists and test pilots based both in Russia and Ozar during the R&D phase up to 2019. HAL will subsequently begin manufacturing the fighters," he added.

Interestingly, after first specifying the requirement for at least 166 single-seat and 48 twin-seat of these 5th Gen fighters, India is veering around to the view that it will go in for only single-cockpit jets now.

"Both F-35 and T-50 are single-seaters. A second cockpit will compromise the stealth capabilities by at least 15% apart from adding to the weight and reducing fuel capacity. Moreover, R&D costs could go up by another $2 billion for the twin-seater," he said.

IAF is confident the swing-role fighter will meet its future operational needs.

As a critical interim measure and confronted with a declining number of fighter squadrons, IAF also wants the almost $20 billion MMRCA (medium multi-role combat aircraft) project to acquire 126 French Rafale fighters to be sealed within this fiscal.

Some good details on PAK-FA from the chief test pilot Sergei Bogdan

Fifth-generation fighter will soon begin test for Super Maneuverability

MOSCOW, August 16 - RIA Novosti. Fifth-generation fighter PAK FA (T-50) will soon begin testing maneuverability, said on Thursday honored test pilot and Hero of Russia, Sergei Bogdan.

Currently involved in testing three prototypes fifth-generation fighter. This year, to connect the fourth plane.

"The plane of the fifth generation in the near future, the program proceeds to test for super maneuverability. And those figures who now plays Su-35, T-50 aircraft in the near future will also be ready to perform," - said in an interview Bogdan "Russia 24".

He noted that unlike the Su-35 (which is a plane 4 + + generation), the fifth generation fighter aircraft greater wing area, larger volume of fuel, the engine with higher thrust.

According to Bogdan, agility T-50 is just more, despite the great demands of his "signature." "There are all conditions that the aircraft will be significantly better than the Su-35", - said Bohdan.

Comparing the T-50 aircraft with an American fifth-generation fighter F-22 "Raptor", he said that our T-50 came later, so all the shortcomings that were identified from the Americans, were taken into account when creating a Russian aircraft.

"Our Su-30MKI in 1997 on the handling characteristics showed no worse than the" Raptor ". Have passed since 15 years. By the fact that" Raptor "shows now, we can judge that by handling it does not beat that plane , "- said Bogdan.

He stressed that the tactical maneuvers with the aircraft Malaysia and India show that Russian planes prevail in a "skirmish."

"I think our strike aircraft developed in the right direction", - said Bohdan.

Interesting. So, there will be only one version of PAKFA, instead of a dual seat version particularly for IAF.

Looks like IAF is not keen on reducing stealth parameters for the price of two pilots.

 

[Apollyon]

Then p2p what will be our contribution in designing -- Nil
I thought this venture was a great opportunity for HAL/ADA to get some experience in designing of a next gen fighter
This will just turn out to be Indian's integrating customized equipment's sourced from around on a Russian designed platform

For me, I thought this venture is a great opportunity for India to waste the $35 billion down the drain in the name of some experience in designing of a next gen fighter.

If some how IAF can not live without another junk.
Then buy as buyer-seller deal.

BTW, Why we are paying $35 billion for the product which is already developed by them?
No need to waste so much money in the name of development cost for T-50 which is already done by the Russians.

In future they will sell it in market, buy it when it is available. Much cheaper way to get it.

 

[A chauhan]

Perhaps IAF wants to avoid possible delays and errors by HAL in designing tandem version.

You want to be in the game, you have to be generous contributor..

Besides DRDO asked for same amount for development of Infrastructure and LAB, Gov gave 2 billion USD, Indian is far away to be self reliant, Which is very dangerous at this stage..

---------------------------------------------------------

Well what option we have now to have a 5th gen fighter is to work with Russian, And Russian are the only one giving full access to there 5 gen program..

FGFA will be like SU-30MKI just in both single and double seater..
