And something about the Al-31FP itself :

The Su-30MKI is powered by the Al-31FP (P for povorotnoye meaning “movable”), which is a development of the Al-37FU (seen in the Su-37 Terminator).

AL-31FP which is designed by the Lyulka Engine Design Bureau (NPO Saturn) is also different from Al-31F (by the same company). The Al-31F is the ‘baseline’ powerplant found in most Su-27 and its variants, and perhaps in the China’s J-10 in the future and lacks TVC. The AL-31FP was only 110Kg heavier and 0.4 m longer than the AL-31F, while the thrust remains the same. Planes equipped with AL-31F can be upgraded to AL-31FP later on without any changes in the airframe. It is being produced now at the Saturn manufacturing facility at Ufa, Russia.

The Al-37FU (FU stands for forsazh-upravlaemoye-sopo or “afterburning-articulating/steerable-nozzle”) basically added 2D Thrust Vectoring Control (TVC) Nozzles to the Al-31F. 2D TVC means that the Nozzles can be directed/pointed in 2 axis or directions – up or down. TVC obviuosly makes an aircraft much more maneuverable. Al-31FP builds on the Al-37FU with the capability to vector in 2 planes i.e. thrust can be directed side-ways also. The nozzles of the MKI are capable of deflecting 32 degrees in the horizontal plane and 15 degrees in the vertical plane. This is done by angling them inwards by 15 degrees inwards, which produces a cork-screw effect and thus enhancing the turning capability of the aircraft.

The TVC nozzles will be made of titanium to reduce the nozzle’s weight and can deflect together or differentially to achieve the desired thrust vector for a particular maneuver. The engine designers are also working to reduce the infrared signature for thrust settings below afterburner.

Also, the 2-nozzles can be vectored un-symmetrically, i.e. each nozzle can point at different directions independent from the other nozzle and thus multiplying the effect.The aircraft is capable of near-zero speed airspeed at high angles of attack and super dynamic aerobatics in negative speeds up to 200 km/h.

TVC allows the MKI for example, to rapidly loose speed and turn in any direction and fire its weapons. The complete range of maneuveres possible in the MKI are impossible on any other combat fighter in production. “We even made a corkscrew spin a controllable manoeuvre – the pilot can leave it at any moment by a single motion of the stick that engages thrust-vectoring and aerodynamic surfaces,” says Sukhoi’s earlier general designer Mikhail Simonov.

Two AL-31FP by-pass thrust-vectoring turbojet reheated engines (25000 kgf full afterburning thrust) ensure a 2M horizontal flight speed (a 1350 km/h ground-level speed) and a rate of climb of 230 m/s. The Mean Time Between Overhaul (MTBO) for the AL-31FP is given at 1,000 hours with a full-life span of 3,000 hours. The titanium nozzle has a MTBO of 500 Hrs.

The Al-31FP improves upon the Al-37FU in two ways:

Firstly, the Al-37FU cannot vector thrust in 2 planes unlike the Al-31FP.

Secondly, the nozzle drive connection is effected now from the aircraft fuel system and not from the aircraft’s hydraulic system. The change-over to the fuel system, to control swiveling nozzles, enhances the dependability of the aircraft and its survivability in air combat.

India is licence producing sooooo many the Al-31FP’s ..now what do you suppose is going on ??

We are assembling all the parts that come from Russia…right ?

I mean with a little effort we can make the same copies of the Russian parts and put it apart like its done for the other engines, right ?

That’s why they sent it to Russia to reverse engineered, but western engine is too complex, the russian engineers couldn’t crack it, the engine then blew up in the test in Moscow..Now, GTRE is begging SNECMA for help.

Stop being riddiculous…..The engine test facilities in Russia are cheap…thats the only reason the engine was sent to Russia. And the engine sent to Russia was the Kaveri not the GE 404.

and what are you thinking next…France will try their hand at reverse engineering ?????

BTW : I must appreciate you imaginative thinking…maybe you must write a science fiction conspiracy theory book or something………good luck 😉

crob, i dont intend to offend you chinese guys around, but you’ve missed these from the article :

Western vendors have provided Chinese aircraft with the MIL-STD 1553B data bus, which now has been installed on new 052 DDGs. China has used a Type-W datalink provided by France

As on the U.S. Aegis ships, such systems can retain many of the original hardware cabinets, but the unique display console might be replaced with a standard shared console including open architecture LAN access. China’s choice of a LAN could be a Russian GOST standard or a Digibus LAN used on French TAVITAC CDS aboard recent PLAN ships.

and do you also debunk these claims from sinodefence ??

The propulsion system might be in the form of CODOG consisting of two Ukraine-made DA80/DN80 gas turbines rated at 72,600hp (55 MW) and two indigenous diesels (Chinese copy of the MTU 20V956TB92) rated at 8,840 hp (6.5 MW).

It is common knodwledge that HQ-9 SAM is made out of the S-300 and the Patriot from Israel.

The antisubmarine warfare suite would be Italian triple antisubmarine warfare torpedo tubes and 12-barrel Type-75 mortars.

and the Type-95 is a chinese copy of the Russian RBU-1200

Incorrect. The Kvant radar is a pure search radar only and lacks fire control Clueless people citing clueless sources do not make things right.

Yeah clueless…check out this link >> http://www.afcea.org/signal/articles/anmviewer.asp?a=992&z=38 … blows the top on the 052c’s non-indegenous hi-tech components.

and sinodefence (although you discredit it) says : Reports indicate this radar system may be a co-development program with the Kvant-Radiolokatsiya company of the Ukraine. The band and performance of this radar have not yet been publicly reported. The radar may be a developed version of that first seen on the 970 weapons test ship, and could either be S-Band or Russian-style X-Band.
http://www.sinodefence.com/navy/surface/052c.asp

and both the links also say that most of the propulsion, anti-sub warfare system, gun, etc.. is all plagerised.

and i found a chinese fellow say this on another forum :

The PAR’s origin is yet unknown, some say its from Ukraine with the help of Chinese scientists, somesay its from a institute within China, some say China stole it during the Clinton years alongside the nuke blueprints

and what about these nuke blueprints :confused:

oh i see that stuff has moved here from the other 2 threads. thanks

oh and about the FC-1’s radar :

The Italian Grifo S-7 fire-control radar was chosen by the PAF to equip its JF-17 Thunder >> http://www.sinodefence.com/airforce/fighter/fc1.asp

and this : Pakistan Air Force officials expressed dissatisfaction with the quality of Chinese avionics and radar systems, preferring European-made systems.

care to explain this carbato ??

So SNECMA, Klimov or General Electric are going to make the Kaveris for the MCA?
At least one of us can’t read.

Pardon me sir, but let me clarify this >>

The State owned Gas Turbine Research Establishment [GTRE] was to indigenously develop the Kaveri engine to power the LCA and MCA. But there have been major slippages in all the milestones. GE, SNECMA, and Klimov had all offered to provide the engines for this aircraft.

But now the GTRE is asking these companies for help in designing the MCA Kaveri instead of asking them to provide the whole engine themselves (if you read the article on the previous page)

and the MCA kaveri details is there at >> http://www.geocities.com/spacetransport/aircraft-mca.html#engine
