New J-10 thread II

[challenge]

The last five modes mentioned, along with others, is said to have been already incorporated on the KLJ-1, which is already the predecessor to the J-10's set. Other modes the KLJ-1 was reported to have included Sea Search and targeting, MTI and GMTI. This is all courtesy of export information for the KLJ-1, which is being marketed for the export J-8IIM. A refined version of this set is in service with the J-8F.

mechanical radar already obsolete,USAF already have plan to retrofit there F-15E and F-18 with AESA,and offering AESA radar for F-16 user.
already there's agreement between US and India,raytheon will assist India in the development of AESA.
European already plan retrofit EF-2000 with CEASAR AESA "as soon as possible"same with sweden with gripen NORA
big question is, the present status of Chinese AESA.

It may as well just show that once they start smoking on something imported, it's hard to break the habit of doing things the easy way out and they end up being half full and half empty, or they end up continuing smoking the stuff. Good thing is the habit is not as widespread as in some other countries.

It looks like Chengdu and Shenyang were both tied down with the J-10 and J-11 programs the past more than one decade, and only started to seriously move on to the J-xx program only recently. If only they have a third company working on the J-XX. 15 years is long period but then again, I guess, there was the question of having the best qualified manpower for the project or any project back then.




At least it shows they have the idea to launch the J-10 from a ramp.
Or maybe they have the intent?

The point is, Shenyang could devote far more resources to the JXX competition since they had the Su 27 blueprints from the Russians to work of the J-11, which freed up a lot of time.

Again what sort of blueprints are we talking about? It's more likely just assembly instructions for the Su-27 kits, minus all the critical technical data and information that really counts. More likely, to indigenize the Su-27 down to the last bolts had required much more effort and time than it had first seemed - perhaps only slightly less effort than building an entirely new aircraft.

The J-10 is powered by a single, Russian-built Lyulka-Saturn AL-31FN turbofan engine (maximum static power output of 12,500 kgf (123 kN, 27,600 lbf)) or a Chinese-built Woshan WS-10A "Taihang" turbofan (13,200 kgf (129 kN, 29,101 lbf)). However, after the government's official acknowledgment of the existence of the J-10, an interview with J-10 pilots (such as test pilot Li Cunbao revealed that a domestic engine is highly unlikely to equip the J-10 in the near future.

In this interview, publicized in January 2007, the pilots claimed that though the domestic Chinese engine could match the performance of the Russian design in every aspect, there was a very serious drawback - the domestic Chinese engine took much longer to reach the same level of performance as its Russian counterpart (according to Mr. Li Cunbao, as well as other pilots who flew the J-10 fitted with the WS-10, it took at least 50% longer, and in several other aspects, almost 100% longer.) Although this would only translate to a ~1 minute difference at most, it was enough to affect the pilot's ability to safely recover the aircraft by restarting the engine rather than abandoning the aircraft in a forced ejection. Another significant drawback of the domestic Chinese engine is the lack of a FADEC (Full Authority Digital Engine Control) feature. This has been addressed, however, the current FADEC-equipped WS-10 is not reliable enough to be considered for service.

that was the old WS-10, not WS-10A. That article had its share of mistakes, it's hard to believe that the first 7 prototypes were all using WS-10 amongst other things. FADEC is an issue, should be addressed with the next variant of WS-10 series.

On the other hand, SAC had more experience with twin engined fighters from the J-18 as well as the canceled J-13 (the one that looked like a MiG-25/F-15).

that's a valid point and that's also why SAC hasn't been left out of it completely. It's a collaborative effort, but CAC will do most of the design. Again, production is a different story. It's very much like F-22 where Boeing/LM are both working on the production.

by the time WS-10A enter service,it may also obselete,already the Rusian is offering new version AL-31 with super cruise capability.

You mean the AL-41?

China has successfully tested the core of its T/W 10:1 engine a year or two ago, I've heard. That doesn't mean anyone in his right mind would actually fly with even a working prototype at this stage.

WS-10a is already in service with the J-11B.

It was reported by Jane's Defence Weekly on 2006-01-09 that a more advanced version of the J-10 is planned, referred to as the Super-10, with a more powerful engine, thrust-vector control, (improved WS-10A? China is unhappy /w AL-31FN) , stronger airframe and passive phased-array radar.

China finally placed an order for 54 AL-31FN M1 engines at $300 million, but no follow-on orders have been placed since then. Various domestic Chinese sources have claimed that the reason for not purchasing anymore AL-31FN M1 engines is that the Mean Time Between Overhaul (MTBO) of the thrust vectoring engine is too short: according to the Russian manufacturer Salyut's claim, thrust vectoring engines of the AL-31F series only have an MTBO of 250 hours compared to more than 1,000 hours of MTBO for the original AL-31F, but Chinese sources claim that in reality, the number is as low as 50 hours MBTO for the thrust vectoring model.

 

[PrOeLiTeZ]

current US and european fighters incorporate net-centric warfare,a pilot can up-load or down load information,this increase "situation awareness".
To date, No PLAAF aircraft such as J-10 and J-11B possess this kind of capability,yet.

well you really cannot make that hard statment, you should mean not to our awarness or knowledge that the PLAAF currently possess that kind of capability. who knows we know neither the J-10 capabilities or its radars. So they might already have it ready to install or are installed aready on a small batch of fighters. none of us really know
