Air China successfully developed the first air-cooled active phased array radar will participate in "Fierce Dragon" radar competition
2017-05-20 09:46:15
Today, the aircraft industry radar research institute (607) official WeChat issued a message, announced the successful development of the international first airborne air-cooled two-dimensional active phased array fire control radar, the recent flight test verification, made a major breakthrough. According to various sources, this radar may be to participate in the "Fierce Dragon" Block3 fighter radar bid and developed, and the CLP Group 14 in 2016 Zhuhai Air Show show KLJ-07A radar to compete.
The new radar is for the Pakistan Air Force JF-17 fighter
607 WeChat in the public said, the new radar is characterized by:
I am the most intimate: I use efficient air cooling technology, successfully solved the deployment of PD radar fighters can not be directly in place with active phased array radar world problems.
I am the most lightweight: the plane only fly more light to fly faster, my air-cooled system for the aircraft to reduce the burden. Flight will be more graceful.
I am most affordable: I embodied the wisdom of the crystallization of engineers, greatly reducing the cost of dressing, shorten the dressing cycle, can greatly enhance the aircraft integrated combat effectiveness.

From the traditional point of view, the rapid development of new equipment after the rapid public news, it is likely to be developed for foreign trade purposes. The official WeChat in the public also have "to improve the international competitiveness of China's airborne radar," the language that this radar is likely to be a foreign trade radar.
If so, then its positioning may be developed with the CLP Group 14 KLJ-07A fire control radar is similar to the foreign trade fighter supporting the active phased array fire control radar.
In March this year, the British "Air Force Monthly," a report mentioned, the magazine interview was informed that the development of Pakistan for the JF-17 Block3 (FC-1 "Fierce Dragon") fighters are manufacturing prototype. China Aviation Technology Group revealed that the fighter radar will be in the CLP Group 14 KLJ-07A and China Aviation Industry 607 developed by a AESA radar between the latter will be equipped with the world's first air cooling system.
If the British related reports do, then 607 of the new radar identity can be determined.
607 is the aircraft industry group developed airborne radar equipment, the main manufacturers. Not long ago,
607 official WeChat revealed that they began to develop a new airborne active phased array radar for the J-15B fighter , and revealed that the radar antenna
technology has made revolutionaryprogress. The PLA Air Force active fighters, J-16 fighters used by the active phased array radar is also developed by the Institute, it is learned that this type of radar on the air target detection distance than the J-11BS used on the mechanical scanning radar increased by 75 %.
However, there are news that the J-16 fighter radar in some working conditions there are problems, leading to improvement before, J-16 fighter some features have to be limited.

Recently JF-17B two-seater fighter
According to information, the last century 70 years, most of the fighter radar are air-cooled. However, after entering the 1990s, with the substantial increase in heat, air cooling capacity has been insufficient, which forced engineers to start using liquid cooling technology, commonly used coolant with ethylene glycol plus water (EGW) or propylene glycol water (PGW).Liquid cooling systems are more complex and expensive than air-cooled systems, but have a higher cooling effect. In the aviation field, due to high airborne air density, liquid cooling technology is more advantageous than air-cooled. For example, at a height of 35,000 feet, the air-cooled efficiency is only 40% of the horizontal level because of the reduced air density. As a result, modern active phased array radars have chosen liquid cooling, including F-22 and F-35 fighters. At present, the United States and other countries are studying double-sided liquid cooling technology, to further improve the efficiency of liquid cooling.
Through the relevant comparison of liquid cooling and air cooling, it can be seen that the air-cooled technology of AVIC can be used on the basis of airborne active phased array radar, which is a new change in radar antenna design. The agency claims to use the "thin" new antenna design for the new radar developed for the J-15B fighter. On the other hand, the use of air-cooled technology also means that the type of radar power may be smaller, or the use of other special design.
The advantage of using air-cooled technology is that the size and size of this new radar may be smaller, lighter, not only easier to install in the "Fierce Dragon" Block3's head, but also can be used to modify the Pakistan Air Force has been more Early "Fierce Dragon" fighter. The radar mentioned in the news has been installed to verify the test flight, perhaps is installed in a modified "Fierce Dragon" BLOCK1 or BLOCK2 type.
In other words, even if the radar in the "Fierce Dragon" BLOCK3 radar bid unsuccessful, is still possible in the Pakistani market to obtain a considerable number of orders, the future can also be used as other countries to purchase "Fierce Dragon" when one of the options, Limited capacity, but also want to get the installation of active phased array radar fighter countries wishful.
This does show that the 607 technology is making progress, but some comments on the Internet that the radar may be used to modify our own fighter, although the possibility is not large, but can not rule out this possibility.
At present, the use of PD equipment, the main fighter J radar, J -10, J -11, J-11B, JH-7A and several other models, which, J -11 fighter mid-term transformation is often talked about the topic The Is now close to install Su -35 fighter air force had previously had the first batch of equipment after the local modernization of the F -11 fighter, but this round of conversion is not large, but the installation of the omnidirectional UV alarm system, Did not involve a comprehensive avionics modification.
J-10B fighter using a passive \ active phased array radar, which before the fuselage was expanded in the cockpit on both sides of the layout of the cooling system
For the former fuselage space is relatively limited J -10A, if the future to adapt to the radar, the use of a body structure can not change the active phased array radar may be valuable, but of course, the premise is that the radar performance is better
But the F-11 fighter part of the nose there is enough space to accommodate the liquid cooling system, 607 has also been developed for the J-16 using liquid-cooled technology of active phased array radar, and also for the J -15B developed a new type of radar The And the J-11B fighter with 14 mechanical scanning radar, J -11D is developed with 14 another active phased array, which J-11D radar was previously J -11 medium-term extension of the program popular.
No matter what kind of program, in the J -11 on the use of air-cooled technology, no new radar, so the J -11 series of modified certainly not use this radar.
The J-10A fighter, the current use of the 14 radar, in order to install the J -10 on the active / passive phased array radar, into the flight has developed a J-10B fighter, which early use of passive phase Control array radar, later changed to active phased array, the machine in order to accommodate the liquid cooling system, specifically widened the nose, in the cabin space on both sides of the installation of a cooling device.
607 where the F-16 fighter radar developed on some of the twists and turns encountered
But as one of China's airborne radar industry, one of the manufacturers, the strength of 607 or some, the high-profile publicity of their new radar is clearly to remind you that the picture shows the 607 for the F-7 fighter developed pulse Pleasant radar
In other words, J-10A fighter if you want to install a new type of radar, may have to consider the new air-cooled active phased array radar. But because the J -10 fighter has been using 14 of the radar, 607 want to open the market, I am afraid have to prove their own strength. Perhaps to participate in "Fierce Dragon" BLOCK3 radar competition, there are 607 of this consideration.
As for the JH-7A, the current use of the aircraft is the 607 radar, if the future JH-7A to modernize the transformation, may also choose 607 new radar. However, JH-7A head space is not particularly tense, should be sufficient to accommodate the liquid cooling system. In addition, with the JH-7B project was shelved, the model of the future development of the road may be relatively narrow.
In summary, for the 607 of the new air-cooled radar, in addition to foreign trade FC-1 block3, the most likely to open the situation in our army may be F -10A modified project. Just, J -10A current age is still short, not to the need for medium-term extension of the conversion time, 607 if you want to seize the opportunity, and now need to verify the performance of new radar. Perhaps, for the 607 of the new radar, "Fierce Dragon" BLOCK3 radar bid for its future development will be a decisive event
