Detail differences of J10-B from original J-10A

The J-10B is a modified variant of the J-10 multirole fighter aircraft, with modifications in airframe and avionics. Chengdu Aircraft Corporation (CAC) of AVIC began to develop a follow-on variant of its J-10 fighter around 2004/05. A J-10B prototype reportedly made its maiden flight in December 2008. Photos of the aircraft began to emerge on the Chinese Internet in March 2009. Once commissioned, the J-10B is likely going to become the standard for later J-10 productions.

Rampless Inlet
The J-10B features a chin-mounted diffuser supersonic inlet (DSI) air inlet. The traditional rectangle-shape air inlet on the J-10 requires a large moveable inlet ramp to generate a rearward leaning oblique shock wave to aid the inlet compression process. The ramp sits at an acute angle to deflect the intake air stream from the longitudinal direction. The air inlets comprises many moving parts, which increases the aircraft’s weight and radar reflections.

The newly designed rampless inlet, first tested on the FC-1/JF-17 fighter design by Chengdu, employs a one-piece bump at the top of the inlet replacing the movable ramp. This eliminates all moving parts on the inlet, lightening the overall weight and reducing the aircraft’s radar signature.

Electro-Optic Targeting System
The J-10B has been added with an electronic-optic targeting system (EOTS) commonly found on all fourth-generation Russian fighter aircraft such as Su-27 and MiG-29. Placed forward of the cockpit canopy to the right, the system comprises an infrared search and track (IRST) sensor and a laser rangefinder, which can detect enemy targets passively without requiring to turn on the fire-control radar, thus reducing the chance of the aircraft being detected. The EOTS of the J-10B is likely based on a Russian design.

Tailfin ECM Pod
The upper edge of J-10B’s tailfin is curved, in contrast to the straight-edged tailfin of the J-10. A large fairing is added to the tip of the tailfin to accommodate electronic warfare and countermeasures (EW/ECM) equipment.

ECM Antenna Array
The J-10B has four black antenna arrays attached externally to the fuselage, a larger one on either side of the cockpit and a smaller one on either side of the rear fuselage near the engine nozzle. The specific purpose of these antennas is unknown but they are thought to be for electronic countermeasures purpose.

J-10B Vigorous Dragon - update

The latest 1035 prototype of the J-10B was photographed at CAC airfield in July 2011, revealing the indigenous WS-10A turbofan engine. This much improved variant (1031 prototype) made its maiden flight on December 23, 2008, powered by a Russian AL-31FN engine. The improvements include a DSI/bump engine inlet which not only cuts weight but also reduces RCS, after a similar design was first tested onboard FC-1/JF-17. The aircraft also features a J-11B style IRST/LR and a wide-angle holographic HUD. IRST enables passive detection of enemy aircraft, making J-10B more stealthy in combat. Its nose appears flatter too, similar to that of American F-16, and fire-control radar is thought to be an X-band AESA developed by the 14th Institute, the first of such type ever being developed for a Chinese fighter aircraft, giving J-10B a stronger multi-target engagement and ECCM capability. Two large pods housing testing equipments are attached under the wings. The tip of vertical tailfin was redesigned as well, featuring a large fairing containing communication and ECM antennas, which resembles that of French Mirage 2000. A rear facing MAWS sensor can be seen underneath the parachute boom. A similar system was tested onboard FC-1/JF-17. RAM coating is also expected in certain areas such as engine inlet and wing leading edges to reduce RCS. The aircraft may be fitted with CFTs in the future to further extend its range. All these improvements suggest that J-10B is equipped with a new generation of integrated electronic system, ranging from radar to EW system. Its mission may be changed from air-superiority to multi-purpose, such as AG or EW. In addition, the aircraft is expected to be powered eventually by a WS-10A turbofan. Overall J-10B is thought to be comparable to American F-16E/Block 60. The 03 prototype first flew in August 2009, with the pitot tube removed from the nose tip. Both 1031 & 1034 prototypes are currently being tested at CFTE. J-10B is very liekly to serve as a testbed for various advanced technologies adopted by the 4th generation J-20 (see below) currently under development at CAC thus may not enter the servive in large quantity with PLAAF. The production of J-10B is expected to imminent (07 batch?).

Even J-10A has JFT like ECM housing on its tail, the difference should be what else J-10B houses in its ECM in addition to J-10A

has the canard position change on latest J-10B

 

[SBD-3]

has the canard position change on latest J-10B

Nop, apparently there is no change in the positioning of Canards, the AS verson's canards look different but they are due to longer canopy, the apparent differences are 1) canopy is gold plated 2) A bit larger than J-10A

Khan Saheb,
In this instance, the statement was made by senior Chinese military leaders and not the Pakistanis.

pshamim,

Sir, pakistan must never get into a pi-ssing match with the u s when it comes to weapons purchase from other sources or even the u s---there is no need for it---it does not make sense for the defence minister of pakistan stating openly at a critical moment that we will give the gwadar port to china---.

First of all---it is years and years away----secondly---it was possibly them who gave it to singapore against all good judgement----even if the media is screaming their heads off---the state needs to keep its mouth shut.

With all this hoopla created around this weapons purchase----we have given the enemy enough time to prepare to make a political retaliation on the world forum and to consider other venues as well---.

The very thing about procuring weapons systems is secrecy---and if that is not possible then denial---and even if that is not possible then silence---. In this day and age of web----it is not possible to keep a lid on the news---but the state must not participate in the manner that it did.

This was done intentionally by the state operatives to get the attention of the pakistani public away from OBL fiasco----and this has also backfired----. The proper thing to have been done was to get on the TV and talk back to the public what the americans did not do for the last 9 years.

China Officially Offers Pakistan J-10 Variant
By USMAN ANSARI
Published: 3 Aug 2011 10:22

ISLAMABAD - China for the first time officially offered Pakistan a variant of its most advanced frontline fighter, the Chengdu J-10 Vigorous Dragon/F-10 Vanguard.

Citing defense sources, the offer was reported in the Urdu press here over the weekend. The offer was made during the recent visit to China by Lt. Gen. Waheed Arshad, the Pakistani Army chief of General Staff.

Official Pakistani interest in the fighter dates back to February 2006, when then-Pakistani President Pervez Musharraf toured the J-10 production facilities on a trip to China. Pakistani government approval for the purchase of 36 FC-20s, a Pakistani-specific variant, was given in April 2006. Service entry was slated for the middle of the decade.

Precise details of the deal are not yet known. However, Usman Shabbir of the Pakistan Military Consortium think tank, said "the initial deal will be for at least two squadrons [at least 32 aircraft] and will be financed by China via a soft, long-term loan."

Analyst Kaiser Tufail said the J-10's operational autonomy would be far greater than that provided by the U.S.-built F-16C.

"It has to be remembered that India refused to consider the F-16C/D and F-18E/F, as they wanted a freer hand in operability aspects as well as technology transfer, which the U.S. was unwilling to provide," Tufail said.

With the J-10, Pakistan would "be able to operate it in an environment not constrained by security restrictions," and could base the aircraft wherever desired, Tufail said. He also said the lack of technology-transfer restrictions from the original equipment manufacturer is a factor.

"The J-10 will provide F-16-class capabilities for Pakistan but without the cost and political encumbrances of U.S.-sourced aircraft," Carlo Kopp of the Air Power Australia think tank said.

"What a J-10 would provide is quantity over any U.S.- or EU-sourced product," Kopp said, though he is still uncertain whether China will supply "pre-loved J-10A…or new-build J-10A or J-10B airframes."

Shabbir said the broader Sino-Pakistani combat aircraft relationship has eroded Western influence over Pakistan, though he remains concerned about the implications Pakistan's fragile economy has for its defense capabilities.

"The availability of J-10 and JF-17 from the Chinese means that Pakistan is now not that reliant on the U.S. and Europe for its aircraft requirements, and this of course will erode U.S influence over Pakistan in the long term," he said.

The Pakistani Air Force is the largest operator of U.S supplied weapons in South Asia and therefore most vulnerable to sanctions.

[ziaulislam]

is the engine same in j-10b and j-10a
if yes..whats really capablities difference between them..other than minor changes..

what i really mean from this point is that if a f-16a/b can be upgraded to f-16c/d standarads (when c/d has a greater wing area and better engine)..why are our members so much upset with an UPGRADED j-10 a

i realy think that even if we get j-10a upgraded, it will be near j-10b capabilities

 

[sohail.ishaque]

Whatever but this had to happen.. and i believe its more to do with the American making India fall to their military equipments.. and to keep them under their strong influence...

Khan Saheb,
In this instance, the statement was made by senior Chinese military leaders and not the Pakistanis.

Improved F-10B subversive China shocked the world (2011-08-03 15:43:49)Reproduced
Tags: Military
April 2009, J-10B for shipping. The first slave to the belly has a very significant change, the whole forming, natural, let the world admire the wisdom and fly into the design level. F-10B disruptive progress for Russia's Sukhoi experts were shocked that the F-10A and F-10B is essentially not a machine.

They pointed out that J-10B is not small change, but including appearance, including a huge improvement. See? J-10A inlet above a few "small stick" has gone. J-10B's appearance is very beautiful, but more important is performance, YST personally think that the J-10B's performance over the United States the latest model of F-16 ** <unfortunately is somewhat less payload and fire some> are three generations of machine in the crowd, some into the fourth generation machine (the body with a plasma stealth device transducers).

A. Inlet

Inlet design is critical for high-performance aircraft, because aircraft at different altitudes, flight speed and attitude to need a different feed rate for combustion, the engine must have a close cooperation in order to get the best combustion efficiency, which directly affect aircraft power, this is not a simple matter, they might even cause the engine air parking, which is very dangerous, high-altitude start the engine with a high degree of risk, so many pilots killed.

J-10B uses the most advanced DSI intake (also known as "clam" inlet), see Fig. Readers in the J-10B of the inlet at the top you can clearly see a bulge, that is, "clam" inlet design. The bulge shape is adjustable to control air imports.

DSI intake has two advantages:

a. Shielding the engine blades, greatly reduces the radar cross section and radar features;

b. Save the inlet and the body of septa, J-10B for DSI intake weight one hundred and eighty kilograms.

DSI intake is the first invention of the United States, but only on the F-35 and is not adjustable. China immediately follow up and it carried forward into adjustable "clam" inlet to improve the efficiency of supersonic flight. Chengdu Aircraft Design has the inlet to the successful application of this advanced in J-10, FC-1 ("Fierce Dragon") and J-20, than its inventor, Lockheed Martin, there are more applications experience.

B. Active Phased Array Radar (Active Electronically Steered Array, called AESA)

"Active Phased Array Radar" is generally defined as the standard fourth-generation fighter, J-10B is equipped, so J-20 will be equipped with active phased array radar.

Today confirmed that J-10B is equipped with Chinese-made phased-array radar, apparently plans to mainland China this advanced electronic products in the J-10B first experiment.

China's neighboring countries have begun or will soon switched phased array radar, such as the French "Rafale", Europe's "Typhoon", Russia's Su-35S, India's Sukhoi-30MKI, and even South Korea's F-15K are U.S. plan to dress the active phased array radar, the Japanese early in 2000, equipped with their own R & D active phased array radar, the 3.5 generation (Western Standard) or after four generations (Russian standard) fighter threat to China, both J-11B or J-10A electronic systems are under pressure, so the J-10B is equipped with Chinese-made active phased array radar is a very natural thing.

Phased array radar is a very important electronic equipment, YST in the next one at the forums.

C. Supersonic cruise

About a year ago reported that YST have seen J-10 supersonic cruise can do short (like 15 minutes), YST guess may be experimenting with new research and development of turbofan-10II (WS-10B) to achieve.

But in China the focus of the target aircraft engines should be "Taihang", currently in production with a small amount of test equipment situation. Recently "Taihang" engine in a growing number of domestic J-11B fighters, and even special emphasis will be installed in the future on the J-15 aircraft carrier, "Taihang" engine reliability will be improved step by step.

J-10B's size and empty weight is only 8.6 tons, smaller than the F-16 **, body light, if equipped with the "Taihang" engine is certainly capable of supersonic cruise for a long time.

D. Invisible

J-10B in the shape significant changes in online leak of the news is an order of magnitude lower RCS. In fact, J-10A when the design has stealth considerations (such as BWB), RCS will not exceed 3m2. If the J-10B to reduce the RCS of an order of magnitude, then it the RCS should be in 0. 3m2 so. In accordance with the definition of YST, RCS is less than 1 is called stealth fighter aircraft, so J-10B could be included in a low-end of the stealth fighter.

E. J-10B will be a low-end machine of the Five Dynasties

November 8, 2009, deputy commander of the Chinese Air Force proud of what China Central Television in an interview revealed that China is "intense" to develop fourth-generation fighters <J-10B,J-20>, "may soon have to make its maiden flight, the first fly and quickly test flight, and soon the troops. According to the present to determine the status of 2011 there may be other stealth fighters will appear.

This is the People's Liberation Army generals at that time heavyweight state-owned radio conversation released by the natural attention, China's fourth-generation fighters immediately aroused heated discussions, the Asia-Pacific balance of power will be completely broken and so, the United Kingdom [Jane's Defence Weekly] According to the current J -20 model even speculated that China's new generation of stealth fighter and combat performance of the local fire performance may surpass the U.S. F-22 and Russian Su-35, T-50.

Mainland China's weapons development has been low-key acting, not like the Chinese military has always lied, trying to avoid the "China threat theory" appears. So a few days out of the Air Force responsible official of the fire, explaining that China is a so-called fourth-generation fighter F-10 an improved type. Zhefan fire was caused by a lot of the Continental Army, then the disappointment of fans.

Today it seems the above two statements are right, how proud of deputy commander, said the J-20, and later the Air Force official said the J-10B.

Mainland China's J-10 as the U.S. F-16, mass production of J-10 is different for each batch, continuous change and evolution of performance, has now revealed the signs of J-10B will meet the "4S" at least become a four-generation low-end machine (the Russian definition of the Five Dynasties machine).

YST very much agree with "Chengdu Aircraft Company," this practice, not the pursuit of extreme performance, or partially beyond the requirements of balanced development, and always able to control the price range of mass production, outside the aircraft to be able to eliminate this is the right way.

Pursuit of a particular aircraft for the ultimate in performance is very unwise, for example, Yu F-22 stealth comprehensive combat capability in the desperate pursuit, the cost scary. Aircraft operations are not singled out but one of the coordinated multi-combat. If the U.S. really fighting in the air early warning aircraft, satellites and various missiles and long-range ground-based radars to support the complex environment of the expensive F-22A J-10B on the cheap may not be an advantage, depending on both tactical and high-angle the use of technology <roar like the U.S. F-18G aircraft electrical power of filial piety by F-22 combat aircraft radar interference, the approaching F-22, re-use infrared heat-seeking missiles to shoot down F-22>. J-20 to face the situation, F-22A's advantage is even more slim. http://blog.sina.com.cn/s/blog_4afeb1160102drk0.html?tj=1

i was guessing correctly , however the link of the picture i had posted previously , is dead so i will post houshangai's version of pictures


there are small changes of canard between j10b pt 01 and j10b pt 05
