Chapter 314： imitation radar

Rectangular air intakes, twin-engine twin tails, and a bubble-style cockpit are so beautiful in appearance, full of power and beauty.

​​

f-15! This is an American F-15 fighter jet!

​​

"The island nation's Self-Defense Force has four existing F-15 fighter jets, three of which were towed back to Moscow, and this one was placed with us, and we are responsible for research." Grishin said.

​​

When East and West Germany merged, the Americans got East Germany's MiG-29 fighter jets without much effort. This kind of Soviet front-line fighter jets took off their coats in front of the West, and left them naked for the West to study. I don't know how many people in the Mikoyan Design Bureau are rooted in this.

​​

And now, it's the Americans' turn to be depressed. Their most advanced third-generation machine has been acquired by their own side! After this research, in the future, in the air battle, the fighters against the Americans will be more certain!

​​

The radome of the nose has been disassembled, and you can see the radar antenna of the flat slot above. Andre can't help but walk over quickly and carefully observe the f-15.

​​

"The first thing we need to do is reverse surveying and mapping to imitate the f-15's airborne radar." Andre said excitedly, looking at the flat radar antenna with admiration.

​​

The Soviet Union's electronic technology was backward until it disintegrated, and it did not overcome the difficulty of the flat-panel gap radar. As a heavy fighter, the Su-27 was originally planned to be equipped with a flat-panel gap radar. A one-ton behemoth, the Su-27 has been improved many times since, almost all around this thing.

​​

Now, the t-10 has not yet started the test flight, and the difficulties in history will not be repeated!

​​

"Yes, our Oe factory, the main task at this stage is to survey and map and imitate the airborne electronic equipment of the f-15, and the radar is the key point." Ohashi Eitaro said: "Although our Mitsubishi Heavy Industries has assembled the f-4 fighter. , but the above airborne radar is also a complete set of imported products from the United States, and the current f-15 was originally intended to be imported and produced, and radar equipment also needs to be imported, but we already have all kinds of parameter files. Radar is related to fighter aircraft We can no longer obtain any advanced technology from the United States in the future, and can only develop it ourselves. All our technicians are concentrating on it, and now we have overcome the difficulty of manufacturing radar antennas.”

​​

Radar antenna! The most important one of the apg-63 radars used by the f-15 fighters in the United States is the flat-panel slot radar antenna. This antenna is to open a crack on the broad or narrow side of the waveguide and arrange it properly to form a linear array or area array. , to meet the requirements of various antenna applications. This method has significant advantages such as high gain, easy control of aperture distribution, and compact structure. Among them, the standing wave array with longitudinal slit on the broad side of the waveguide, that is, the flat slot antenna, also has the characteristics of low loss, light weight, large power capacity, high polarization purity, and high mechanical strength. These advantages have allowed the United States, which attaches great importance to electronic technology, to first use the fire control radar on fighter jets, the seeker antenna of missiles, and so on.

​​

The Soviet Union's radars are five big and three thick, and the power is extremely high, but the actual utilization rate is quite low. Among them, the low efficiency of the radar antenna is an important aspect, and most of it has turned into heat to dissipate! Although the Soviet Union wanted to overcome the difficulty of flat-panel gap radar, it was difficult.

​​

The most important of them are materials and precision machining technology! These technologies, the Soviet Union could not have obtained from the West.

​​

"It's great!" Andrei was very happy to hear this. He naturally knew what it meant. As long as the manufacturing difficulty of the radar antenna is overcome, with the electronic technology level of the island country, the processing system and other components behind it can also be All can be conquered one by one, in this way, just in time to catch up with the development progress of Su-27!

​​

The electronic technology of the Soviet Union, because of the reciprocation of the island countries, will have a blowout improvement! After catching up in electronic technology, see how the Americans confronted the Soviet Union militarily!

​​

"Once this radar is successfully developed, we will equip our fighters and simultaneously export them to our friends. In the future, we can also consider the technical output and directly produce these radars in Moscow," Ohashi Eitaro said.

​​

This is almost certain. After all, some of the Soviet Union's personnel were involved in the research and development of this radar. If the research and development is successful, the Soviet Union will master the technology at the same time, but the processing level in the Soviet Union is insufficient. If it is produced in the Soviet Union, it needs The introduction of mechanical processing equipment. At that time, how to do cost accounting, profit, etc., is not something that Andre can worry about.

​​

Moreover, the future fighter planes and radar systems of the Soviets must not rely on the factories of the island countries. If the islanders have any bad intentions, they will deceive the Soviet aviation.

​​

"Mitsubishi Heavy Industries is also quite advanced in the development of phased array radar, and they are overcoming the difficulty of the t/r component of active phased array radar." Grishin said: "We are also joining in, and strive to develop more advanced as soon as possible. active phased array radar.”

​​

Although the Soviet Union already has an airborne phased array radar, it is a passive phased array radar that relies on ferrite phase shifters. The new active phased array radar is the future direction! In this regard, the island has a forward-looking technology and, with the cooperation of Soviet experts, jointly overcome technical difficulties.

​​

"In addition to the tireless development of the radar, there is another team that is studying the engine of the f-15 fighter." Ohashi Eitaro said: "It's just that the engine of the f-15 is not mature yet, facing the Too many problems, the last time it was because of an engine failure that caused a large-scale grounding of American aircraft."

​​

Engine! In fact, the Soviet Union's pursuit of engines is not as urgent as avionics, because the Soviet Union is not outdated in engine development, but the technology of Soviet engines is still flawed, such as service life, which is far from the level of the West. Studying Western engines is still helpful for the Soviet Union to master more cutting-edge engine technology.

​​

It is the F100 engine, which is still facing various reliability problems. If it wasn't for the large-scale grounding of the F-15 last time, the Americans would definitely not be so easy to admit defeat!

​​

Wait, engine, avionics, if the island nation has conquered all these technologies, and there is one airframe left, it means that the island nation has the ability to independently develop and produce fighter jets? Thinking of this, Andre's heart suddenly became alarmed.

​​

Although the technology of the island country must be used now, it is absolutely impossible to cultivate the island country into a military power!

​​

"We still have a new plan." At this moment, Ohashi Eitaro said: "Originally the next-generation fighter of our Self-Defense Force is the f-15, but now, I am afraid that the plan is going to fail, we need a new fighters to deal with future conflicts.” (To be continued.)
