JF-17 Block-3 -- Updates, News & Discussion

IMO, this is unrealistic to expect. GaA to GaN will require a different fabrication process at the semiconductor substrate and wafer level which will increase development and testing costs. And doing it for 50 +10 copies only wont justify economy of scales.

Well PLAAF / PLAAN need for GaN is in hundreds if not thousand plus, so RoI is there for manufacturer. It will be costly for PAF, they will just have to weigh in cost / benefits and go with the best possible deal on KLJ-7A.
 
We might witness top notch Turkish gadgets showing the capability through Thunders. Just a matter of time. I was however thinking that why most of the times, we somehow hear or read that there is a tailor made solution or tailor made weapon out of existing platform, can be due to our own "Data Link". Yes, a weapon has to operate in network solution as well if needed and that is the area that most leading/advance/professional Air Forces are working to contain the rival. Therefore, things may take time but as the one says "It (Thunder) will be (In'Sha"ALLAH) not just showcase capability & power but also, will shock the enemy.
Post 5225 is exactly the same .....

Is there any chance of UAE showing interest in Block 3 o_Oo_O ?
I don’t see any requirements or anywhere it can fit in UAEAF
UAE and SA both are annoyed ..... currently in bad mood ...Pakistan is more towards Turkey/Qatar/Malaysia....Kashmir is not being included in OIC agenda despite Pakistan's repeated requests.
So B3 is not in their interest.
 
Well PLAAF / PLAAN need for GaN is in hundreds if not thousand plus, so RoI is there for manufacturer. It will be costly for PAF, they will just have to weigh in cost / benefits and go with the best possible deal on KLJ-7A.
Well, yeah, you are right, if PLAAF has requirements for same RADAR.
 
Well PLAAF / PLAAN need for GaN is in hundreds if not thousand plus, so RoI is there for manufacturer. It will be costly for PAF, they will just have to weigh in cost / benefits and go with the best possible deal on KLJ-7A.
It is not the return in terms of Material, but in terms of research and expertise which can be invested for another many decades and centuries.

Doubt that the USA will allow AIM-120C mating with the JF-17 even if it carries Western Radar, ( not stating that PAF is / will not be able to mate it or lacks the capability. ) The risk of suspension of Spare parts for the F-16 fleet would be too much for PAF to risk it, I am 99% sure if not certain ( sorry unable to provide documents to back it ) that clause of sale is that these weapons will only be used with F-16s.

Last I knew / read was that USA was not to pleased with the mating of the AIM-9 series on the F-6 platforms.

As far comment on JF-17 Block-III having J31 DNA ? first of all no one knows if J-31 has any DNA except for the outer shell, so that comment is pure speculation based on personal opinion, now if you say J-10c / J-20 as someone stated in one of the above post than one will likely agree on that even if no proof is available to validate the statement.

As for 6-8 JF-17 attacking IoJK backed by Chinese AEW / AWACS, well there were F-16 providing top cover along with a Blinder, so we will still have to wait to validate true capabilities of Chinese EW for now.
A little correction, the US actually helped with mating the sidewinders with the F-6. Subsequently we have F-7 and Mirages using AIM-9Ls too.

Recently, foreign media revealed that the Pakistani Air Force has made significant progress. The Pakistani Air Force has ordered 26 Dragon two-seaters, 12 of which have been delivered from this year. The first 4 are manufactured by the Chengdu Aircraft Corporation of China and the remaining 8 are in Pakistan. Kamla ’s aviation consortium manufacturing continued the trial flight test of Chengfei. After the test flight matured, the technical information was transferred, and then experts were sent abroad for guidance. The Pakistani aviation consortium followed up!

The two-seater Chenlong fighter equipment will greatly simplify the training of the Pakistani Air Force ’s Chenlong fighter pilots. In the past, due to the lack of a Chenlong two-seater trainer, the Pakistani Airmen ’s Chenlong pilots were selected from the F-16, J-7PG, and Mirage IIIEA units. Mature pilots changed their flight. As time passed, a large number of fighter jets were delivered, making this approach of moving the east wall to fill the western wall more and more difficult to cope. Today, Pakistani pilots need only complete advanced trainer training before they can be directly launched. Long two-seater trainer, and then become a qualified Chen Long driver!

The rapid batching of the Xiaolong two-seater fighters has greatly accelerated the training of the Pakistani Air Force's Xiaolong fighter pilots.

This is not the most explosive news. The most exciting news is that after more than 2 years of careful comparison of test flight test evaluations, the phased array radar battle of the third batch of dragons of the dragon finally came to fruition. The radar king Nanjing 14 The KLJ-7A radar did not unexpectedly come to the end. This high-performance liquid-cooled radar easily defeated the air-cooled radar of the AVIC Thunder and Lightning Institute. From the results, the Pakistan Air Force did not fully value the price, but paid more attention to the KLJ-7A. High performance, combined with China ’s new high-speed data link with three batches of equipment, it is possible to combine the Dragon 1 and 2 batches of fighter jets and two-seater models under the command of the Chinese-made ZDK-03 large-scale airborne early warning aircraft, combined with Chinese-made air defense on the ground The radar network, combined into a skynet, can cope with the gust fighter offensive of India!

The first prototype of the third batch of Xiaolong made its first flight at the Huangtianba Airport in Chengdu on December 17 last year. Lieutenant General Said Norman Ali, the new chairman of Kamla Pakistan Aviation Group, stated that Two prototypes will join the test flight team in May this year for flight testing. The Pakistani Air Force plans to equip 28 aircraft, and the total number may eventually exceed 100.

14 radars have almost no disadvantages in radar bidding, and Nine Dragons radar is monopolized

Relying on performance and price advantages, the radar king defeated the French RDY-400 and Italian GRIFO advanced pulse Doppler radar, and monopolized the first and second batches of the Phenom radar. Their company's KLJ-7 radar is lightweight and reliable. High, long detection range, radar function is highly trusted by the Pakistani Air Force. Although it weighs only 120 kg, it is comparable to the 1,000 kg radar performance index of the Su-30MKI fighter of the Indian Air Force. This is a new level of manufacturing in China: not only price Cheaper, with greater advantages in performance.

In the third batch of radar competition, the opponent changed from a foreign manufacturer to a domestic brother manufacturer: the same brother unit in Jiangsu, Wuxi Thunder and Lightning Institute, although the Thunder and Lightning Institute radar also meets the needs of the Pakistan Air Force, but 14 radars are still more Advanced design and higher performance win successfully. These highlights are mainly reflected in the fact that the radar uses liquid cooling technology to make the fighter aircraft able to withstand high-intensity air combat for longer periods of high-power and high-performance work. The use of air-cooled radar for high power Very poor tolerance, this is a huge difference!

b946-inzcrxs9265022.jpg

Although the radar design of Thunder Academy has the advantages of easy replacement and cheap price, it still loses to the more aggressive 14 products.

In addition, the 14 institutes also learned from the successful experience of the J-20 fighter jets and adopted a tilted radar front design. This design can reduce the aircraft's head-on radar reflection cross-section to a minimum, while the opponent's radar has been installed vertically in the front. , The survivability is higher, and the designer also adopted the world ’s most advanced phased array radar antenna design, borrowing the European Typhoon fighter active phased array tilt rotation technology, the radar scanning range has been almost doubled, this is a Unparalleled upgrade, no need to install multi-faceted radar antennas, it can be achieved on one side. After the KLJ-7A is equipped with the third batch of fighter jets, it will be equipped with advanced air-to-air and air-to-ground missiles imported from China. Launch a thunderous attack on enemy targets from a distance.

Beginning in 2006, Xiaolong fighters began to be delivered to the Pakistan Air Force, including 6 prototypes and the first batch of 8 pre-production models. These aircrafts were manufactured by Chengfei. Subsequently, Chengfei sent a large number of technicians and workers to help Mullah Pakistan. The aviation consortium produced the Jiulong fighter jets. During the 10 years from 2009 to 2019, it successfully manufactured 42 first batches and 64 second batches of fighter jets. The quality is also quite reliable, making Pakistan ’s aviation industry manufacturing level from the second generation Upgrade to three generations!

The Pakistani Air Force also likes the dragon dragon fighters very much. Pilots can perform air combat and ground-to-sea attack missions. They have performed abroad many times. Since the price is less than 20 million US dollars, this has gradually opened the dragon dragon fighter's international market. Including Myanmar and Nigeria began to buy Phenom fighters, Myanmar ordered 16 aircraft, and Nigeria to purchase 3 aircraft. Over time, the third batch of Phenom equipment equipped with active phased array radar will also be exported in large quantities, which is the cheapest in the world. Three generations of semi-fighters, with powerful multifunctional combat capabilities.

2 points:

- The radar antenna as you can see in the picture is at a tilted angle which reduces the frontal RCS of the fighter

- The radar antenna (like the euro fighter CAPTOR E) is mounted on a movable mount that can swivel the antenna in the direction of scanning/tracking hence doing away with the need of side antenna as in the 3 array version of KLJ7A.


Let’s see how reliable this report is as they are saying the radar is liquid cooled where as Alan Warnes is adamant that it’s air cooled version.

Confirmed! Xiaolong-3 fighter will rule the sky of South Asia, phased array radar crushes the American F-35!

According to Jane ’s Defense Weekly on February 4th, the Pakistan Air Force began to receive the first batch of 12 “Dragon” two-seater fighters. At the same time, the radar model of the “Dragon” Block3 was determined. Pakistan finally selected KLJ-7A. Type active phased array radar, this radar was developed by Nanjing 14. Although the prototype of the JF-17 "Baolong" Block3 fighter aircraft has successfully completed its first flight some time ago, it has not been possible to determine which radar the "Bailong" Block3 fighter aircraft will adopt.

1000


The third batch of improved dragon fighters made their maiden flight in mid-December 2019. The Pakistan Air Force was numbered JF-17 Block3. This indicates that the development of the Xiaolong fighter has made gradual progress. Three batches of Jiulong were equipped with new avionics systems, wide-angle diffractive holographic display, integrated cockpit display, distributed optical aperture system, KLJ-7A airborne active phased array radar, integrated avionics based on fiber optic data bus, The overall combat capability of airborne weapons has been significantly improved. It is currently the most advanced light fighter in the world. Its combat effectiveness is comparable to that of the Swedish Gripen E, which has effectively strengthened the Dragon's competitiveness in the international market. Originally regarded as one of the most important improvements in the "Bailong" Block3 fighter project, it is no secret that the "Bailong" Block3 is retrofitted with a source phased array radar. However, the question of which active phased array radar to replace was shrouded in fog. Everyone has many speculations, including the LKF-601E air-cooled active phased array radar at Wuxi Institute 617, the KLJ-7A active phased array radar at Nanjing Institute 14, and some models from other countries. Affected by innate conditions such as the size of the "Nine Dragons" fighter head and the power generation power of the RD-93 medium engine, the "Nine Dragons" Block3 fighter has a lot of restrictions on active phased array radar. You must find one for it "Ruyi Langjun" is not easy. Fortunately, China has a strong and complete defense industry system, which is sufficient to effectively meet the research and development needs of this level of products. In the end, China launched two products that the Pakistan Air Force can choose from, namely the KLJ- 7A active phased array airborne radar and AVIC's LKF601E air-cooled active phased array radar.

1000


These two active phased array radars have their own characteristics and strengths. The KLJ-7A radar is a comprehensive upgrade and improvement model of the KLJ-7 radar developed by CLP Nanjing 14. The KLJ-7 radar is a type of pulse Doppler radar equipped on the Chinese dragon fighter aircraft. Compared with the KLJ-7A radar, the biggest change is the replacement of the radar antenna from a mechanically scanned flat slot antenna to an electronically scanned phased array antenna to become an advanced airborne active phased array fire control radar. The radar is X-band, with functions such as air search, multi-target tracking, air-ground and air-sea target search and tracking, high-resolution SAR imaging, high-gain ESM, electronic countermeasures, terrain avoidance, and weather.

The special advantage of KLJ-7A radar is that its comprehensive performance is very strong. Although its aperture is only 600 mm, it integrates more than 1,000 T / R components. The KLJ-7A radar has amazing detection capabilities. There are even official claims that the combat capability of the KLJ-7A radar is enough to rival the APG-81 radar equipped with the F-35 stealth fighter. The KLJ-7A radar can stably identify and lock a target with a reflection area of 3 square meters at a distance of 170 kilometers. 3 square meters is approximately the size of a J-7 fighter.
The CCTV program also showed the subjects of the KLJ-7A radar test flight, which is to simultaneously search and track multiple fast maneuvering targets at distances of up to 100 kilometers at an altitude of 3000 meters, and complete weapon simulation launch, verify the radar's multi-target detection capability and tracking stability. The LKF601E radar's unique strength is that it is currently the world's first airborne radar that uses natural air cooling. It debuted at the Zhuhai Air Show in 2018 for the first time. As an active phased array radar, after the LKF601E radar adopts air-cooled heat dissipation technology, the antenna and other control equipment units are designed to be very compact, and the volume and weight of the entire airborne radar are significantly reduced. The fighter is undoubtedly very attractive, because the LKF601E radar can be directly installed on the early production "Jiaolong" Block2 fighter, without having to make too many structural modifications. At the same time, its radar detection performance is also excellent, the detection range of fighter targets is more than 150 kilometers, it can track 15 targets at the same time, and launch attacks on 4 of them. The only disadvantage of the LKF601E radar is that the efficiency of the air-cooled system affects the detection performance, and it will decrease with the increase of the flying height. As the fighter's flying height increases, the air density becomes thinner, resulting in a sharp reduction in the cooling efficiency of the radar air-cooling system. This can be solved by reducing output power and reducing the density of T / R components, but the overall performance is not as good as the KLJ-7A radar with a liquid cooling system.

1000


The latest information shows that at present, both KLJ-7A and LKF601E radars have completed installation tests and product development has been basically completed. Considering that the prototype of the JF-17 "Baolong" Block3 fighter has made its first flight, which means that the competition between the two radars has been decided, the KLJ-7A active phase control of the 14th China Nanjing Electronics Group Corporation was selected.
Airborne radar, which is good news for the "Jiaolong" Block3 fighter. In the future, with the support of advanced avionics equipment such as advanced active phased array radar and new large-scale diffractive head-up display, the "Nine Dragons" Block3 fighter will achieve another leap in combat performance.

1000


The N001M fire control radar of the Indian Su 30MKI fighter aircraft uses a passive phased array system, which has a large size and weight. The actual detection index is far inferior to that of the Chinese KLJ-7A radar.

1000


Picture: American APG-83 radar, which is a low-cost AESA radar designed for F-16V conversion, uses a large number of F-35 APG-81 radar technology.

The KLJ-7A active phased array radar has a combat distance of 170 kilometers, which outperforms the Zucker N011M passive phased array radar currently used on Indian Su-30MKI fighters. Equivalent performance, but also has the advantages of late technology and price. According to an important description of the KLJ-7A active phased array radar at Nanjing Institute 14 at the Zhuhai Air Show, although the KLJ-7A radar is smaller than the APG-81 radar equipped on the F-35 stealth fighter, its combat capability is completely Can be compared with APG-81 radar. It is not difficult to imagine how powerful the KLJ-7A radar used for export is. The Dragon 3 Blocker equipped with phased array radar is likely to become a popular product in the international market.

At the same time, the radar model of the “Dragon” Block3 was determined. Pakistan finally selected KLJ-7A. Type active phased array radar, this radar was developed by Nanjing 14. Although the prototype of the JF-17 "Baolong" Block3 fighter aircraft has successfully completed its first flight some time ago, it has not been possible to determine which radar the "Bailong" Block3 fighter aircraft will adopt.

The third batch of improved dragon fighters made their maiden flight in mid-December 2019. The Pakistan Air Force was numbered JF-17 Block3. This indicates that the development of the Xiaolong fighter has made gradual progress. Three batches of Jiulong were equipped with new avionics systems, wide-angle diffractive holographic display, integrated cockpit display, distributed optical aperture system, KLJ-7A airborne active phased array radar, integrated avionics based on fiber optic data bus, The overall combat capability of airborne weapons has been significantly improved. It is currently the most advanced light fighter in the world. Its combat effectiveness is comparable to that of the Swedish Gripen E, which has effectively strengthened the Dragon's competitiveness in the international market. Originally regarded as one of the most important improvements in the "Bailong" Block3 fighter project, it is no secret that the "Bailong" Block3 is retrofitted with a source phased array radar. However, the question of which active phased array radar to replace was shrouded in fog. Everyone has many speculations, including the LKF-601E air-cooled active phased array radar at Wuxi Institute 617, the KLJ-7A active phased array radar at Nanjing Institute 14, and some models from other countries. Affected by innate conditions such as the size of the "Nine Dragons" fighter head and the power generation power of the RD-93 medium engine, the "Nine Dragons" Block3 fighter has a lot of restrictions on active phased array radar. You must find one for it "Ruyi Langjun" is not easy. Fortunately, China has a strong and complete defense industry system, which is sufficient to effectively meet the research and development needs of this level of products. In the end, China launched two products that the Pakistan Air Force can choose from, namely the KLJ- 7A active phased array airborne radar and AVIC's LKF601E air-cooled active phased array radar.

1000


These two active phased array radars have their own characteristics and strengths. The KLJ-7A radar is a comprehensive upgrade and improvement model of the KLJ-7 radar developed by CLP Nanjing 14. The KLJ-7 radar is a type of pulse Doppler radar equipped on the Chinese dragon fighter aircraft. Compared with the KLJ-7A radar, the biggest change is the replacement of the radar antenna from a mechanically scanned flat slot antenna to an electronically scanned phased array antenna to become an advanced airborne active phased array fire control radar. The radar is X-band, with functions such as air search, multi-target tracking, air-ground and air-sea target search and tracking, high-resolution SAR imaging, high-gain ESM, electronic countermeasures, terrain avoidance, and weather.

The special advantage of KLJ-7A radar is that its comprehensive performance is very strong. Although its aperture is only 600 mm, it integrates more than 1,000 T / R components. The KLJ-7A radar has amazing detection capabilities. There are even official claims that the combat capability of the KLJ-7A radar is enough to rival the APG-81 radar equipped with the F-35 stealth fighter. The KLJ-7A radar can stably identify and lock a target with a reflection area of 3 square meters at a distance of 170 kilometers. 3 square meters is approximately the size of a J-7 fighter.
The CCTV program also showed the subjects of the KLJ-7A radar test flight, which is to simultaneously search and track multiple fast maneuvering targets at distances of up to 100 kilometers at an altitude of 3000 meters, and complete weapon simulation launch, verify the radar's multi-target detection capability and tracking stability. The LKF601E radar's unique strength is that it is currently the world's first airborne radar that uses natural air cooling. It debuted at the Zhuhai Air Show in 2018 for the first time. As an active phased array radar, after the LKF601E radar adopts air-cooled heat dissipation technology, the antenna and other control equipment units are designed to be very compact, and the volume and weight of the entire airborne radar are significantly reduced. The fighter is undoubtedly very attractive, because the LKF601E radar can be directly installed on the early production "Jiaolong" Block2 fighter, without having to make too many structural modifications. At the same time, its radar detection performance is also excellent, the detection range of fighter targets is more than 150 kilometers, it can track 15 targets at the same time, and launch attacks on 4 of them. The only disadvantage of the LKF601E radar is that the efficiency of the air-cooled system affects the detection performance, and it will decrease with the increase of the flying height. As the fighter's flying height increases, the air density becomes thinner, resulting in a sharp reduction in the cooling efficiency of the radar air-cooling system. This can be solved by reducing output power and reducing the density of T / R components, but the overall performance is not as good as the KLJ-7A radar with a liquid cooling system.

1000


The latest information shows that at present, both KLJ-7A and LKF601E radars have completed installation tests and product development has been basically completed. Considering that the prototype of the JF-17 "Baolong" Block3 fighter has made its first flight, which means that the competition between the two radars has been decided, the KLJ-7A active phase control of the 14th China Nanjing Electronics Group Corporation was selected.
Airborne radar, which is good news for the "Jiaolong" Block3 fighter. In the future, with the support of advanced avionics equipment such as advanced active phased array radar and new large-scale diffractive head-up display, the "Nine Dragons" Block3 fighter will achieve another leap in combat performance.

1000


The N001M fire control radar of the Indian Su 30MKI fighter aircraft uses a passive phased array system, which has a large size and weight. The actual detection index is far inferior to that of the Chinese KLJ-7A radar.

1000


Picture: American APG-83 radar, which is a low-cost AESA radar designed for F-16V conversion, uses a large number of F-35 APG-81 radar technology.

The KLJ-7A active phased array radar has a combat distance of 170 kilometers, which outperforms the Zucker N011M passive phased array radar currently used on Indian Su-30MKI fighters. Equivalent performance, but also has the advantages of late technology and price. According to an important description of the KLJ-7A active phased array radar at Nanjing Institute 14 at the Zhuhai Air Show, although the KLJ-7A radar is smaller than the APG-81 radar equipped on the F-35 stealth fighter, its combat capability is completely Can be compared with APG-81 radar. It is not difficult to imagine how powerful the KLJ-7A radar used for export is. The Dragon 3 Blocker equipped with phased array radar is likely to become a popular product in the international market.

Ba Tielong dragon fighter staged the Chinese version of the "radar war" behind the twists and turns

A few days ago, "Jane's Defense Weekly" published a report on the latest progress of the China-Pakistan FC-1 "Jiaolong" / JF-17 "Thunder and Lightning" fighter project, including the "Jiaolong" latest improved "Jiaolong" Block III Information, it is reported that the first prototype of the "Baolong" Block III has made its first flight in Chengdu on December 17, 2019, and the second prototype will also be put into trial in May this year.

The report disclosed for the first time that the "Baolong" Block III finally selected the KLJ-7A of the 14th China Electric Power Research Institute in Nanjing as its airborne active phased array fire control radar, which is the core of all aircraft upgrades. The author of the report is a British journalist who has a close relationship with the Pakistan Air Force, so the report is very credible. What kind of radar is used by the "Baolong" Block III can be described as twists and turns. Today, the CN military station (WeChat ID: Sinomilitary) tells the story behind this.

cbbc-ipfprtp3638341.jpg

△ "Baolong" Block III has made its first flight at the end of 2019, but the first prototype does not seem to have a radar installed

The use of an airborne active phased array fire control radar for the "Baolong" Block III was determined early in the project's inception. The only uncertainty is which radar to choose. China Electric Power Research Institute 14 and AVIC 607 both Provide their own airborne active radar products to participate in the bidding. The strength of both units is good, and related products have also served in the Chinese Air Force by a certain order of magnitude.

According to public information, the minibus was a radar model that was determined at the last moment, which also made this "radar war" protracted. The two units have their own advantages, and they are still trying their best to compete for this hundreds of orders and high profits.

0de2-ipfprtp3638410.jpg

△ The 14th KLJ-7A airborne active phased array fire control radar was exhibited for the first time in 2016. This is the first time that a domestic airborne active radar was exhibited.

Although this "radar war" was launched between two Chinese military industrial enterprises, the meaning behind it was not ordinary. Behind this "radar war" can be called the epitome of Chinese military occupation of high-end military electronic technology. This can be seen from From two perspectives:

First, although China is the main weapon supplier of minibuses, China's provision of weapons to minibuses is by no means "what do you buy?" Almost any weapon, especially the main battle weapon export minibus, is more or less Few are participating in competition with countries such as Europe and Russia. At the beginning of the development of the "Jiaolong" fighter, the minibus wanted to equip the "Jiaolong" with a European fire control radar. Only when the 14th agency took the action did the minibus say "I don't want to."

From the beginning to the end, the "radar war" surrounding the "Brontoon" Block III was not played by European manufacturers. High-performance airborne active radar is at the peak of military electronics technology. The absence of European manufacturers in the "radar war" Although it cannot be said that China has surpassed Europe in this field, with the continuous expansion of scientific research investment and use scale, related technologies It will be sooner or later that the field will show its strength.

1653-ipfprtp3638485.jpg

△ U.S. Version of the "radar war" was finally won by APG-83. Its manufacturer Northrop Grumman was also the development unit of F-22 and F-35, but APG-83 is clearly a compromise product for the export and upgrade market

Second, this "radar war" also proved that the overall level of China's military electronics technology has reached a very high level. At present, only three countries in the world, China, the United States, and Russia, have more than two companies with the ability to develop airborne active radars. However, Russian products have not been put into service, so the current high-speed propulsion on airborne active radar lanes must be China and the United States.

Interestingly, a similar "radar war" was also played in the United States 8 years ago. At that time, Northrop Grumman and Raytheon in the United States were competing for South Korea, Singapore and other countries and regions for F-16 upgrade orders (with clear use Demand for active radars (more than 300 aircraft), launched APG-83 and APG-84 airborne active radars, and started protracted competition. Northrop ’s APG-83 finally laughed to the end. However, APG-84 also received upgrade orders for the U.S. Marine F-18 in 2019.

The "radar war" between China and the United States is quite similar. The companies in the two countries have developed related technologies to a certain degree, and after meeting the domestic demand for fifth-generation and fourth-generation and half-fighter aircraft, they will gradually evolve. Products are launched to the international market, and the list size is not small. It can be said that since the relevant technology has obtained export licenses, it is no longer a sensitive technology for this country. Exporting it can not only enhance its influence in the international market (even geopolitics), but also be very beneficial to the long-term healthy development of the company itself. helpful.

c379-ipfprtp3638540.jpg

△ Pakistan's "Jiaolong" was photographed carrying the Perak-15 missile, but if there is no active fire control radar, the long-range advantage of this missile will not be exerted

The "radar war" surrounding the "Baolong" Block III was all Chinese companies, and everyone was naturally "easy and happy" to watch. But for the companies in the bureau, how dare they be sloppy in the face of these hundreds of millions of orders? From the comparison of the strengths of the two companies, as the birthplace of China's radar industry and the industry's "Big Mac", the 14 companies have monopolized the fire of all aircraft of the J-10, J-11B, J-15, and J-20. With the development of radar control, the overall strength is naturally superior. At the 2016 Zhuhai Air Show, the KLJ-7A became the first airborne active phased array radar on display in China to become the focus of the audience. The "radar war" may have begun since then.

If the 607 is to launch a similar product to the 14 KLJ-7A to compete for "equal and stable", the result may have long lost its suspense. The 607 institute has a unique approach for this. In 2017, it was announced that it had successfully developed the world's first airborne air-cooled two-dimensional active phased array fire control radar LKF-601E, and achieved significant breakthroughs after flight test verification. With the appearance of LKF-601E, the competition has undergone subtle changes. In the eyes of the outside world, the competition of product models has become a "technology line dispute" to a certain extent.

1add-ipfprtp3638606.jpg

△ Institute 607 launched the air-cooled LKF-601E airborne active radar in time to show its resilience and technical strength, but it is still a glorious defeat

The so-called air cooling is a cooling method for aircraft radar systems. Active phased array radar has good performance, but also has high power, and requires better cooling methods. This is what all "old-fashioned" aircraft must upgrade to active radar. One difficulty. Although the "Nine Dragons" Block III adopts a new design, it is difficult to fundamentally change the original structure because of its small size. Therefore, its upgrade is similar to the "in-situ upgrade" of F-16 aircraft. Airframe structure or wiring changes must not even change the status of the aircraft's only air-cooled interface and its cooling distribution.

And high-performance active phased array radar often adopts liquid cooling method to take away the heat of the antenna (aircraft liquid is introduced into the radar system for cyclic cooling), which has the best heat dissipation effect. However, the structure of the complete liquid-cooled system is also complicated. It is very difficult to directly use the "old-fashioned" aircraft and fighters with limited airframes. The American (F-16V) method is a compromise method, that is, the radar antenna is still liquid-cooled and reused. The original air-cooled channel cools the coolant to achieve heat dissipation. The advantage of F-16 in doing so is to maximize the weight and volume of the liquid-cooled conversion unit inside the radar, and to keep the antenna structure in line with "conventional radars" such as F-22 and F-35 to the maximum extent. There are mature designs to achieve serial and general development. It is generally believed that KLJ-7A adopted a similar technical route at least early.

f15f-ipfprtp3638668.jpg

△ F-20, F-35 and other new aircraft use on-board radar using liquid cooling technology, because they represent the latest technology in their country, the relevant technology will inevitably be used on other models. Air-cooled models are not conducive to serialization and general development

The air-cooled design used by the LKF-601E is the third technical path other than liquid-cooled, liquid-cooled / air-cooled mixing, that is, by optimizing the antenna's heat conduction performance, directly using the cooling wind that comes with the aircraft to dissipate heat. This design used to be It has also been used in helicopter-borne radar. The 607 institute first used it in airborne active phased array radar is indeed the first. The advantage of using air-cooled design for airborne active radar is that the structure is relatively simple and does not take up too much resources of the aircraft, but three disadvantages are also very prominent: one is that the radar power is severely restricted; the other is that the antenna array is difficult to uniformly dissipate heat; three It is not conducive to the serialization and general development of mainstream products.

If it is a new type of heavy and medium-sized fighter aircraft, air cooling technology can be said to have absolutely no way out, but it has quite a lot to do on the light "Jiaolong". The reason is that the radar used by the fighter requires trade-offs in terms of structure, technology and performance. The "Longlong" itself has limited aircraft resources. Even if it uses active phased array radar, it can only be a compromise product. In the case that there is not much power that can be "wasted", if the "Longlong" uses air-cooled active radar, it can also achieve the purpose of simplifying the aircraft design.

50c3-ipfprtp3638723.jpg

△ The KLJ-7A radar tested on the Yun-7 should not be better than the 607 of the AVIC Group.

The 607 is obviously aiming at this opportunity, decisively grabbing the "jackpot" of the air-cooled radar (the KLJ-7A also had a similar scheme at the beginning), so that the "radar war" became more intense. From this, it is not difficult to see the outstanding resilience and technical vision of 607, and of course, it also has the technical strength to solve the problem of air cooling technology.

It is just that the strength of 607's opponents is too strong. At the Zhuhai Air Show in 2018, 14 companies further demonstrated the "wide-angle solution" of KLJ-7A. The characteristics are fully absorbed and quickly transformed into actual products. This kind of action has no effect even at the international level. In addition to strong technical strength, public information shows that the 14 schools and minibuses are also very close. The country ’s land-based and The space-based early warning system was organized by 14 companies, and the 14 companies also provided minibuses with the KLJ-7 aircraft fire-control radar production line used in the early batches of the "Liaolong". Therefore, it is not surprising that KLJ-7A can finally win.

ff21-ipfprtp3638794.jpg

△ The KLJ-7A radar wide-angle solution exhibited in Zhuhai where 14 is located combines the advantages of products from Europe, Russia and other countries in one

It is worth noting that at the Zhuhai Air Show in 2018, 14 companies pointed out that the KLJ-7A can also be air-cooled and has related solutions. The "Jane's" report just pointed out that KLJ-7A wins with air-cooled technology! Someone asked the original author whether this was a typo, but the author replied that the solution provided by KLJ-7A to the minibus did include two technical forms, liquid cooling and air cooling. Well, this may be a very dramatic result. After setting off a "technical dispute", the LKF-601E was eventually "anti-killed" by the more powerful KLJ-7A with the same technology.

Taken together, the Chinese version of the "radar war" is not inferior to the American version a few years ago in terms of technical level and intensity. In addition to the results, the overall improvement of many Chinese military companies in the field of electronic technology is even more gratifying ...

TAKEAWAYS:

1. This proves that KLJ-7A indeed comes in two modes as far as cooling mechanism is concerned.
2. There are three cooling techniques of AESA; i. Pure liquid cooling ii. liquid+air cooling mixed iii. pure air cooling
3. What Institute 607 was trying to do was adopt 3rd technique.
4. KLJ-7A most probably is going to use 2nd technique. (this is what I got from this report.)
5. Pure Air Cooling, at least so far, has 3 major disadvantages; Low Range of Radar, Not able to cool the entire antenna uniformly, low probability of serial production as tech needs to be matured.

This article made me lose my mind.
Too many names are used here for thunders.
Baolong, Bailong, dragon, jiaolong, jiulong.

@Deino , in the first or i guess the second para, it is mentioned, 3 batches of jiulong were equipped with.

What is that ?

No, i am really serious bro, i had a bad day and a bad week, and this article really made me go ape angry. Irritated by this translation.

And the one posted by PakFactor is more annoying, it mentions that 64 of batch 2 has been produced and 42 of batch 1, but block 1 are 50 in total, what a total misinformation.
