Outlines of PAK FA​

Thursday, October 22, 2009

Since the article of Alexander Pachkov ('Paralay') in Nov, 2009 issue of Russan-language 'Popular Mechanic' journal has produced a great interest, I translated the short essential of this text. Paralay is the editor of the popular site 'Stealth Machines'. The article is about PAK FA/FGFA program. Since I cannot check the Paralay's sources out, the question of information reliability is up to a reader. The outlines of his article:

1) Can hope for 10-15% PAKFA advantage over F-22 due to two decades of tech. development.

2) F-22 detects Su35 from the distance of 150-180 km but can open fire from 110 km, while becomes visible for Su-35's radar by itself and on R-77 range of attack.

3) OLS-35 probably detects Raptor on 100 km distance.

4) PAKFA's AESA radar has probably 1526 modules with overall power 18 KWt. Range for a big air target – 400. TWS/A = 60/16.

5) Active antennas in the wings and tail are probable.

6) OLS with 360 deg.

7) Backward attacking missiles.

8) Has up to 12 Air-to-air missiles (if compact) in internal placement.

9) Two internal bays for WLRAAMs and LRAAMs up to 700 kg each. + 2 bays for short range missiles.

10) While Raptor can have up to 8 missiles in the internal bays.

11) WLRAAM 'Izdelie 810' is MiG-31 R-33 derivative. 400 km.

12) LRAAM 'Izdelie-180PD' is air-breath R-77 derivative. 250 km.

13) 'Izdelie-180' – solid-fuel R-77 derivative 110-140 km. With active and passive radar, homing on jammer.

14) Short range AAM – 'Izdelie-300' or K-MD IR matrix, double range of homing.

15) Kh-58UShKE

16) Kh-35

17) 500 kg guided and unguided bombs and cassette munition.

18) Intrafuselage cathapults UVKU-50L – up to 300 kg, UVKU-50U – up to 700 kg.

19) Internal bays total weight 2.000 kg

20) With + external hardpoints – 6.000 kg.

21) GSh-30 30 mm autocannon.

22) According to the plans – 430 planes must be built for RuAF.

23) Probably price $80 mil.

24) Will replace 339 Su-27 and 300 MiG-31







Defunct Humanity: Outlines of PAK FA

 

[sathruvinasakh]

Russia is looking to have atleast 300 PAKFA/FGFA while India is optimistic of Inducting atleast 200 of the same(ofcourse with a difference in the variant)

And I highly doubt MCA flying before 202.Since a lot of workforce has to put on for FGFA,MALE,HALE,IRJ-90,MTA,UCAV,.......

Unless something happens and the manpower increases dramatically,we cant hope for MCA at the earliest.
But one good thing will be that,by 2020 MCA design will be frozen with 3 or 4 different models and the most technologies needed will be developed by then.Hence only integration and tech upgradation needs to be done.And also Indian side will be burping with a lot of tech being chewed by then.

Code words for 'we are trying to keep up but are not having much successes in doing it.'

2) F-22 detects Su35 from the distance of 150-180 km but can open fire from 110 km, while becomes visible for Su-35's radar by itself and on R-77 range of attack.

Highly improbable. The F-22 and F-35 are self-aware of their own calculated RCS with respect to the transmitter. In other words, if the F-22 is aware of the source transmit direction, it will perform a calculation of its physical dimensions against the transmitter's position and will alter its flight profile to present the least RCS to the aggressor radar. Launching an air-air missile is part of this equation. If it is possible to launch a missile with the weapons bay opening sequence NOT facing the aggressor transmitter then the aircraft will perform the maneuver. Even if it is not possible for the F-22 to mask its opened weapons bay, the opening and closing sequence are so quick...

F-22 Raptor - Wikipedia, the free encyclopedia

Launching missiles requires opening the weapons bay doors for less than a second, while the missiles are pushed clear of the airframe by hydraulic arms. This reduces the Raptor's chance of detection by enemy radar systems due to launched ordnance and also allows the F-22 to launch long range missiles while maintaining supercruise.

That the aggressor radar will not have sufficient statistical data to determine if the F-22 is in the area.

Many of these sources do not inform their readers that radar detection is essentially a statistical process, meaning it is time dependent to acquire a target. Airliners are called 'cooperative targets' as they DO want to be detected. So it is not usually difficult to find an airliner. Fighters are usually 'non-cooperative' targets and it is already difficult to find them when they are working their hardest to avoid the aggressor radar. Now throw in an aircraft whose body is to date the most 'non-cooperative' yet and these people are saying that an open bay door make the aircraft vulnerable? No wonder I do not take Russian or Chinese sources seriously.

OLS-35

Description: The OLS-35 is an advanced infrared search and track (IRST) fire control system designed for the 4+ generation Su-35 fighter aircraft replacing the OEPS-27 sight system. OLS-35 comprises a heat-seeker, a laser rangefinder/designator and a TV camera along with new algorithms and advanced software to outperform its predecessor installed on the Su-27/Su-30 aircraft family. The Su-35 IRST is superior to the OEPS-27 in terms of range, precision and reliability.

The OLS-35 provides a coverage of +/-90 in azimuth and +60/-15 in elevation with a target acquisition range for non-afterburning aerial targets of 50 km facing up to target's front hemisphere and 90 km facing up to rear hemisphere. The laser rangefinder features a five-meter Circular Error Probable (CEP) and ranges up to 20 km for aerial targets and 30 km for targets on the ground.

Specifications
Performance: Azimuth Coverage 180 °, Coverage in Elevation 75 °, Max Detection Range 90 km (49 nm) rear hemisphere of non-afterburning aerial targets, Measurement Accuracy 5 m (16 ft) laser rangefinder

What about Raptor's heat signature?

OLS-35


What about Raptor's heat signature?

Infrared is a passive sensor, meaning the system must rely upon target characteristics to infer information. IR detection is unreliable on true target range. The system essentially guess on target distance based upon IR emission intensity under ideal environmental conditions.

MILAVIA Aircraft - Sukhoi Su-35 (Su-27BM) "4++ Generation Flanker"

The estimated range for detection from a tail-on aspect has been reported to be 70-90 km and up to 40-50 km for head-on engagement for non-afterburning targets.

In a head-on engagement, an aircraft's IR emissions are from leading edges as they heat up due to friction. Nothing so bright as the exhausts, hence the halved distance compared to the tail chase situation. Tactically speaking, the system offers no advantages as if this is a head-on engagement the Su would be detected by the F-22's radar long before the F-22's IR emissions is detected. AMRAAM ranges are longer than 50km.

The detection and tracking zone is 55-60 ° upwards, 15 ° downwards, and between 60° and 90° in azimuth.

So we have a detection zone that has a bias that is favorable to the Su if the Su is below the target and actually quite narrow in azimuth -- side to side. In effect, the system is best if the Su is below and directly behind the target.

it seems really the architecture of this Aircrat is really inspired by F-22

Russia's T-50 Nears Flight Test

Sukhoi has delivered the second prototype of the fifth-gen T-50 Future Air Complex for Tactical Air Forces (PAK FA) tactical fighter to the Russian Air Force and static tests have commenced. The flight prototype will be rolled out in 11/2009, but first flight has been delayed. The PAK FA, designed to replace the Su-27, features an avionics suite from Ramenskoe Design Bureau, network centric capabilities and X-band radar from Tikhomirov NIIP. NIIP has also unveiled an L-band active phased array radar that has apparently been designed for installation on the T-50's leading-edge flaps. It has also been reported that the first PAK FA prototype, details of which are classified, will be powered by a pair of NPO Saturn 117S engines.

"On 20 August 2009, Sukhoi General Director Mikhail Pogosyan said that the first flight would be by year end. Konstantin Makiyenko, deputy head of the Moscow-based Centre for Analysis of Strategies and Technologies said that "even with delays", the plane would likely make its first flight by January or February, adding that there could be at least 10 years between the first flight and commercial production."


That statement doesn't bode well. 10 years before commercial production? India would have been much better off spending their billions invested in PAK-FA program. With the F-35 or I suspect the coming F-22 export version.

Russia to start 5th generation fighter tests in 2010 - deputy PM

Russia will start tests of its fifth-generation fighter in 2010, Deputy Prime Minister Sergei Ivanov said on Tuesday.

"The trials will begin in 2010," Ivanov said. Earlier reports said test would start before the end of this year.

Deputy Defense Minister Vladimir Popovkin has said the fighter, which has been under development since the 1990s, will enter service with the Air Force in 2015.

Russia's one known fifth-generation project is Sukhoi's PAK FA and the current prototype is the T-50. It is designed to compete with the U.S. F-22 Raptor (the world's only fifth-generation fighter aircraft) and F-35 Lightning II, but has yet to take to the skies.

The T-50's maiden flight has been repeatedly postponed since early 2007 for unspecified reasons.

However, in August 2009, Russian Air Force Chief Alexander Zelin said that there were problems with the engines and research was ongoing.

The PAK FA is believed to possess advanced avionics, stealth capability, a ferry range of 4,000 to 5,500 km, and endurance of 3.3 hrs; it is armed with next-generation air-to-air, air-to-surface, and air-to-ship missiles, and has two 30-mm cannons.

Russia to commence flight tests of FGFA

Moscow: Russia will soon flight-test the fifth generation fighter aircraft (FGFA), which is developed along with India, a senior cabinet member said here today.


"In the end of December-beginning of January, we are not making any New Year presents, but flight tests will start shortly," Deputy Prime Minister Sergei Ivanov said.

Under an agreement signed in October 2007, India has also joined Russia in the project based on Sukhoi's PAK FA project and the two nations are in negotiations to finalise the commercial contract for the deal.

At least three prototypes of FGFA have been made by the KNAAPO aircraft plant in Komsomolsk-on-Amur and several Indian teams have visited the facility in the country's Far East near the Chinese border, sources told.

The FGFA is to compete with the US F-22 Raptor and F-35 Lightning II and the Russian Air Force plans to induct the futuristic fighter from 2015.

According to the local media the FGFA is to be equipped with the 'artificial intellect', advanced avionics and stealth capability.

With several mid-air refuellings it could cruise for hours at the supersonic speed

 

[Moscow]

time and again we believed that static tests were on and people were downplaying russia and its delay for the first time ever KNAAPO the company making the PAKFA have released a confirmation of the static tests and that engines were powered on and the planes jogged on the runway with inhibition


here is a transation of the original article in russian dated 24/12 /2009
remember its not yet another source its confirmed by KNAAPO who are the makers confirmed by interfax

Lenta.ru: Îðóæèå: Íà÷àëèñü èñïûòàíèÿ ðîññèéñêîãî èñòðåáèòåëÿ ïÿòîãî ïîêîëåíèÿ


Russia a promising fifth-generation fighter - a promising frontline aviation aircraft complex (PAK FA) - the first jogging at the airfield of Komsomolsk-on-Amur Aircraft Production Association (KnAAPO). It is reported by Interfax, citing a source in the aviation industry. When it was held rollout of the aircraft and began his test was not specified.
After the rollout pilot started the engines and the plane started moving on the runway. During jogging PAK FA several times carried inhibition. Results produced two jogging. During the test was observed only employees KnAAPO. As expected the end of 2009 PAK FA will do some jogging, and in January 2010 made its first flight.

Earlier, Vice-Premier of Russia Sergey Ivanov declared that the test fifth-generation fighter will begin in late 2009-th - beginning of 2010. In mid-September 2009 Deputy Defense Minister Vladimir Popovkin announced that PAK FA, also known as T-50 and the product 701, will enter the Air Force of Russia with 2015.

Ministry of Defense of Russia plans to begin procurement PAK FA after it is fully executed contract to supply 48 Su-35 generation "4 + +". The first Su-35 military aircraft Russia will have in 2011, a contract for the supply will be fully implemented by 2015. On the number of PAK FA, which intends to buy the Defense Ministry, while nothing is known.

Officially, Russia's specifications prospective fighters were not reported. Presumably, PAK FA will be able to reach speeds of up to 2,1 thousand kilometers per hour. Range aircraft will be 5.5 thousand kilometers. Armament plane can be represented by 30-millimeter cannon. PAK FA will have 16 points of suspension, including eight located inside the fuselage.
