PAK FA - full speed ahead
Posted by Bill Sweetman at 2/13/2009 1:14 AM CST

Maxim Pyadushkin: It seems that the Indian Air Force initially receive the same version of the PAK FA as their Russian colleagues. General Director of Sukhoi Pogosyan said Thursday that he would seek ways unifitskatsii requirements of Russian and Indian sides for the fighter. "The basic version of the fighter will be the same," he explained. "The difference is only in software."
India has agreed to join the PAK FA program in 2007. In accordance with the contract modification for the development of the Indian Air Force will be jointly Sukhoi and India's HAL in the ratio 50:50. But now, it seems, Pogosyan not want to spend time and effort to develop a special Indian version at this stage, but intends to focus on rolling out the first prototype by August this year that has already been promised by the Russian government and military officials of higher rank.
Pogosyan also noted. that the glider is almost ready, while more time was needed for it to finish the job with the radar. This confirms the idea that the first PAK FA will be a simple prototype, and it will take more time out to determine the layout and test the production version.
As Pogosyan said, the requirements of the Indian side may be taken into account later, while in the distant future can be realized HAL participate in the development of an Indian modification on the condition of 50% of the division of the program - including a double and deck options.

INDIA AND RUSSIA CREATE DIFFERENT VERSIONS OF FIGHTER 5 th generation

Russia and India, which are jointly developing a fifth generation fighter, will create different versions of the aircraft. As RIA 'News' about that today told reporters in New Delhi, the head of Hindustan Aeronautics Limited (HAL), Ashok Bhavedzha. HAL is a partner of Russia on the Indian side for the production of aircraft. This corporation is also engaged in licensed production of Su-30MKI. According Bhavedzhi, the Indian version of the fifth generation fighter will double, while Russia - single.
Chapter HAL said after the meeting of the joint Russian-Indian intergovernmental commission on military-technical cooperation, which demands the creation of two-seat aircraft are dictated by the doctrine of the Indian Air Force. In fact, acknowledged Bhavedzha, both countries will simultaneously develop two versions of the aircraft.
"Planes will have different wings, different control systems and radars", - quotes RIA 'News' section HAL.
He stressed that the parties have divided responsibilities. India's position is particularly strong in the field of composite materials for aircraft, he said.
'The strength of India - in the production of composite materials, because our technology is the best' - said Bhavedzha.
The plane, he said, would be 'invisible', gained the ability to attack multiple targets simultaneously.Pilots will be able to maintain a stable relationship with the pilots of other aircraft and ground services.

India's role in Sukhoi project

"India is preparing to start work on a future single-seat fighters, the fifth-generation technology demonstrator that will rise into the sky in 2009, together with Russian design bureau Sukhoi.
Some analysts have questioned the contribution of Indian engineers in the program, provided that the plane was almost ready to make a flight next year.
Future Technology: Su-30 fighter aircraft the Indian Air Force, shown at the air show in 2007 in Bangalore, India and Russia are working together on developing it further. In October, the country signed an agreement to establish a fifth-generation fighter (FGFA), with participation in a project on an equal footing.
A team of specialists Hindustan Aeronautics Ltd and HAL have visited Moscow in late May to discuss the contribution of $ 4 billion, as one of the participants: "The more we draw from the entry, the less we get in the project."
Demonstrator, with forward-swept wing (obviously there just to keep flying the Su-47 Berkut "- paralay), which increases maneuverability and reduces visibility to be equipped with engines, systems and airborne equipment the previous generation aircraft Su-30.
The new commander of the Indian Air Force BK Pandey said, despite the fact that a prototype has already been determined, however, the Indian industry could contribute to the program. For example, in the application of composites. 
Russian and Indian companies will build an equal number of experimental machines. Russia plans to build at least six single experienced fighters. Indian specialists will participate in the development of forward fuselage in reducing ESR and equipment on-board equipment. The nose part will be subjected to change (to accommodate two pilots instead of one on demonstrator), change the wings and other elements. All of this will infuse the work with Indian engineers.
The new aircraft by almost a third lighter Su-30 (obviously refers to a normal takeoff weightFGFA - paralay), has a greater range than today's fighters, and less visibility. Taking up arms in India and the Russian Air Force is expected in 2018.
Russian-Indian fighter capable of carrying weapons on the inside of the suspension, which unites him with an American strike fighter.
Production aircraft will be manufactured in Komsomolsk-on-Amur and at the factory HAL, engines NPO Saturn. Both parties are planning to build the same number of fighters ...."

In Indian blogs are beginning to publish a very interesting material on the joint development with Russia, the fifth generation fighter. Writes a blogger ...
Recently there has been considerable clarity in the development of this major military project. It is about creating an Indian version of the program, called FGFA (Fifth-Generation Fighter Aircraft).The project was known in Russia as "The Medium Combat Aircraft (MSA - Medium Combat Aircraft). But it must be admitted that the realization of this futuristic program, as well as the modernization of the aircraft carrier Admiral Gorshkov »(INS Vicramaditya) and a project to develop medium airlifter MTA (Multi-role Transport Aircraft) is facing an acute shortage of highly qualified engineers and skilled workers throughout Russia. 
Around mid-2007, Moscow agreed to focus their efforts on harnessing the limited human resources to create the required set of production facilities to get rid of dependence in this area of ​​enterprises in Belarus, Georgia, Kazakhstan and Ukraine. Russia believes that such a dependence, which is observed particularly acute in the early 90's, had robbed her significant part of export revenues from the sale of weapons systems, as well as the limits of its intellectual property to develop new types of weapons.
This process is very important for India. For example, Moscow has created United Aircraft Corporation (UAC), which included the corporation Sukhoi, MiG and TsAGI (Central Aero-Hydrodynamical Institute). Today, this unified structure is developing fifth-generation fighter the PAK FA, as well as derived from it FGFA (draft MCA), together with the Indian organization for research and development of defense systems (DRDO - Defence Research & Development Organisation). This 17.2-tonne aircraft developed by Russia only to export to, and that's why this program were involved in India and Brazil. For foreign companies this aircraft is offered for 2012, however, is not excluded and the date 2018.
However, the main Russian fifth-generation fighter program is a project of the PAK FA (promising aviation complex tactical aviation) weighing 24 tons, which will be created as a plane to gain superiority in the air like the American F-22 Raptor. Consequently, the fighter FGFA would be developed exclusively as an export and will be financed only by private entities, and to this end there removed 85% of the budget. This emptiness is compensated by the participation of the Indian HAL corporation and the Brazilian EMBRAER (Brazilian has signed a contract with Rosoboronexport on April 15 this year).
This means that the Russian PAK FA aircraft will enter into the composition of the Russian Air Force since 2012, and export project FGFA will be ready around 2015. 
Prototype T-50 PAK FA will be equipped with engines of the type 117S, developed and manufactured at the Moscow Motor Production Association (MMPO) Salut. This engine is a deep modernization of the existing AL-31F turbofans with thrust in afterburner 14.5 tons (two tons more than the base model) and extended to 1500 hours-of-life overhaul. Production aircraft will be equipped with new engines AL-41F is also developing MMPO "Salute", the production of fighter aircraft will be deployed at the Komsomolsk-on-Amur Aircraft Production Association (KNAAPO).
Beginning of Russian-Indian cooperation on the development of fifth generation fighter goes back to November 2002, when Moscow and New Delhi signed a corresponding Memorandum of Understanding. Until that time, Russia is planning to operate independently, but lacked funding for this program.
Moscow in 1998 chose the Sukhoi company as a developer of new aircraft, rejecting a draft twin-engined fighter-2000 Development Design Bureau. Mikoyan and Yakovlev. The power plant production of T-50 PAK FA will consist of two AL-41F engines with afterburner Thrust 155 kN (about 16000 kg). This engine is in development since 1985. In 2002-2004, was designed by digital mock aircraft. May 18, 2003 it was agreed on the establishment of fifth generation fighter aircraft the efforts of companies such as Federal Space Agency, Yakovlev Design Bureau. Sukhoi Military Industrial Complex Sukhoi, NPO Saturn, ICD "Vympel", NPO Zvezda-Strela, TsAGI, the Corporation for space instrumentation, RDC Ramenskoye "Plant" Polet "," Technokompleks, NIIP them. Tikhomirov, Ural Optical and Mechanical Plant, KRRTI, Ufa Motor Company, LII. Gromov and Research Institute in Zhukovsky, MMPO Salut. It was decided that the first flight of the T-50 PAK FA at the end of 2009, construction of seven flight specimens for testing, the beginning of mass production scheduled in 2011, and the introduction of combat aircraft in the Air Force in 2012.
In early 2005, when the Yakovlev Design Bureau. Dry FGFA presented a draft for the Indian Air Force was very surprising that the double Indian version will be easier for single Russian plane to 5 tons. The fact that Sukhoi offered the Indians a limited technical proposal for the single engine version of the aircraft, which was rejected by the Indian side as not meeting its requirements. In December, EDB introduced a twin-engined version of the FGFA, based on the aerodynamic configuration with forward-swept wing. The proposal included a 50% share participation of the Indian side in this project. Yakovlev Design Bureau. Sukhoi also require immediate funding of the program in the amount of $ 300 million in time to prepare a detailed project the airplane.
In addition, Saturn and Ufa MPO has proposed the transfer of India's license to manufacture AL-31FP engine plant in Koraput. Both Moscow and New Delhi agreed that this is a very important step towards each other as till then Russia will never transfer technology to the production of military aircraft engines overseas, including the production of 1,500 engines of this type to equip the Indian Su-30MKI, collected by Russian license at the factory HAL. Engines to the assembly plant comes fully equipped in Russia.
Under the new scheme of cooperation, India and possibly Brazil, eventually will fund a program to develop FGFA by 90% (total program cost is estimated at 2 billion U.S. dollars). Thus, single Russian T-50 PAK FA, which decided to abandon the scheme with forward-swept wing, will be ready for testing in 2009, and its Indian version of the FGFA flight two years later. Russia has made efforts to modernize the AL-31FP to increase its thrust by 20%, which will provide a flight at supersonic cruising without the inclusion of the afterburner. Life of the engine equipped with a digital control system to reach 6000 hours, thrust vector will be deflected vertically by + / -15 degrees, and horizontally by + / -8 degrees.
Single-crystal turbine blades engine will be covered by anti-corrosion system, a new generation of development of the Ural factory Prado, which will significantly increase engine life. Regarding the development of avionics and avionics export aircraft, Russia has every right to engage in their development of an Indian organization DRDO. India itself will develop the electronics with an open architecture and integrated system of electronic warfare. In addition, the Indian aircraft will be equipped with a fiber optic digital control system as opposed to digital by-wire aircraft SU T-50. This management system will be established jointly by DRDO and the Brazilian company EMBRAER.
Radar AFAR will be developed with the participation of French company THALES, Israel Aerospace Corporation, the Russian firm "Fazotron, the Swedish Ericsson and the European Defence Association EADS. Price for double FGFA is currently estimated at 65 million U.S. dollars.

After reduction of the above facts are the following questions. 

1. Is it possible to create on the basis of two-seat fighter FGFA single option, especially since India has experience in software development MRTA, LCH, LOH and a helicopter carrying capacity of the middle class?
2. Who will be the modernization of the glider?
3. Who will produce an aerodynamic venting projected corporation HAL fighter FGFA? Russia or India?
4. Who will hold the intellectual property of the plane FGFA? Or will it be owned jointly by HAL and the Russian United Aircraft Building Corporation?
5. Who will define the characteristics of advanced control system for an upgraded single FGFA?
6. Who will develop algorithms for optoelectronic control system aircraft in Russia's inability to develop such a system? Will there be given a right to non-Russian company?

7. Will the corporation HAL to modernize the AL-31FP engine without the recommendations of the Indian Agency for Air Navigation Development and the Indian Air Force? HAL, or join forces with Saturn to create the turbofan engine Kaveri and set this as the sole powerplant for the equipment FGFA?
8. Will HAL major developer redesigned version of the FGFA, or attract other actors to implement the program?
9. Why the Indian Air Force decided to create just double fighter FGFA? If a fifth generation fighter aircraft to be double, it is not whether this will lead to a contradiction with the tender for the MRCA, according to which will be acquired by double multipurpose fighter of the fourth generation? 
10. Can the command of the Indian Air Force to draw the right lessons from development programs fighter LCA Tejas, creating a coherent structure and control over the entire course of the program FGFA?

Thus, a joint project FGFA radically different from the version for the Russian Air Force.

As was clear from the above publications, single-engined version weighed in at five tons less than the current T-50, ie around 25 - 27 tons, as the F-35. And it requires a motor with a thrust at least 20 tons (probably P-179-300 afterburning power 21,000 kgs). We must assume that initially the project represented the development of lung frontline fighter C-52 .

Twin-engine version, has received approval for further development, can be considered a full receiver front-line MiG-29 and direct descendant of topics PRL.

Normal takeoff weight of 17.2 tonnes, maximum - 23 tons. Swept wing. Obviously, the power plant of such a machine will consist of two engines with reheat thrust of 11,500 kg.

Price topic (2 billion U.S. dollars) and year of the first flight (2012) inspire serious concerns about the feasibility of this program. Room themes PAKFA 8 - 10 billion dollars, but now a new wing, new engines, fiber management, but actually a new aircraft, all at a 4 billion $ (a joint contribution by Russia and India)?

Signing the agreement on development FGFA once again showed that the program multi-functional fighter (IFIs) and light tactical fighter (PRL) has not been canceled. MFI - T-50 , PRL - FGFA, and the role of ground attack - LMFS from MIGA or the development of T-12 from Sukhoi.
 

That's what seemed IFIs and PRL in early 2000:

"PRL fifth generation.
What would submit it to the size, look at the rocket R-77, which should be placed in the inner compartment, 6 pcs. or 4 P-77 + 4 P-73. Ie, he is clearly larger than that of Mig-29.
Compartment of a weapon, missiles are placed on the drum set, the location of rockets allows the launch of two without rotating drum. 23 mm. gun in the right-wing influx.
Bye.
On the wings of two options: a) the swept wing, and b) trapezoidal wing with a slight angle swept by the trailing edge. 
Fully functional PGE + Regulators (the so-called triplane).

When using the new development of engines with thrust vectoring (not to be confused with the SWT, different principles of the "mechanics" Weight - 380 kg of thrust vector angle - 16 ° in all directions, the speed of the thrust vector deflection - 60 ° / s, the ability to regulate the area of ​​the nozzle in depending on flight mode is available.) scheme glider can change. For example, using thrust vectoring may not polnofuntsionalnoe PGO. 2 keel, the crew of 1 person. 

According to IFI's can say that the concept is the same, the wing trapezoidal, wider choice and number of suspension arms. Using both airplanes Freefall bombs from internal compartments will not be covered.

What would be some sort of figurative representation have to compare with known aircraft:

Fuselage + intakes + nodules - reminiscent of the F-18 Superhornet, form a slightly different air intakes, flows are long, ogival on edge. With a tail like Mig-29 (keels + stabilizers + engines + combs). The plan above is somewhat similar to the MiG-29 and F-18. "
