"We have a lot of tasks recently, Old Song, or you can take this matter." When he came to Tu Lao's office, Tu Lao seemed a little busy there.

The busier you are, the more things you do.

"Lao Tu, you're not interested enough." Song Lao said: "You are a production factory, of course, you are obliged to do these tasks, and you are most familiar with them." ”

The two of them simply communicated with each other about this task, of course, this was just a politeness, after all, the superiors had already determined it.

"Besides, this is also to help our 011 base, and when you need it, you have to pull them along." Song Lao continued.

Now they are talking about the project improvement of the J-7III.A.

"Yes, our improvement also has to divide the labor, how to install that engine, you make suggestions, the layout of the avionics on the nose, we can copy the current mature experience." Tu Lao said.

In the past few years, the 132 factory has mainly worked on the avionics of the J-7, so now, of course, you have to pick up the ones you are most familiar with.

"We upgraded its avionics equipment, mainly by replacing the previous HK-03D optical sight with a head-up display, installing a JL-7A fire control radar, and other electronic systems, which have also been added to reach the current mainstream level."

Wait, JL-7A radar? Hearing this, Qin Feng immediately became curious: "What kind of radar is this?" ”

In China, the most lacking is the radar technology, the current J-7, the nose is still equipped with a radar rangefinder, only to provide a distance data for the fire control system, even so, at the time of the test flight, the Marconi company's electronic equipment showed that it was not adaptable, and it took a long time to solve it, now, what is this radar?

Hearing Qin Feng's words, Song Lao explained: "This radar was developed after we surveyed and mapped the MiG-21MF radar, combined with our own 317 radar, and was named JL-7. ”

In March 1966, in order to meet the needs of the use of the Qiang-5 attack aircraft, the country carried out further research and development on the basis of the original, through the mapping and development of foreign prototypes, after ten years, it finally matured, equipped with the Qiang-5 aircraft, the radar model is 317.

The nose of the strong five is large enough to accommodate this radar, but the J-7 is not enough, the nose space of the J-7 is too small, until the MiG-21MF is obtained, it is combined with the design of its radar, and such a radar is made, although compared with other airborne radars of this era, it has long been outdated, but after all, it can still be used, giving the J-7 fighter all-weather combat capability, and now since the J-7III is to be improved, of course, it is necessary to replace it with a new radar.

As for the advanced radar that is reequipped with the J-8 fighter, it must be backward, and the gap in China in this regard is not small! Song Lao knew what Qin Feng was thinking, but Rome was not built in a day, and his own advanced avionics could not be done in a day!

Qin Feng nodded, yes, he was too anxious.

And the engine?

"Our turbojet-13 engine, which is also undergoing power improvement and increasing thrust, is now named turbojet-13F1 engine, Lao Song, these are handed over to you, you must have experience in this design."

Song Lao could only take over, after all, the original surveying and mapping imitation was carried out in 611, they have a full set of drawings, and it is easy to modify these.

In recent years, the turbojet-13 engine is also gradually maturing, due to the increase in thrust than the turbojet-7 engine, so this engine has been recognized by everyone, not only the current J-7III, the follow-up model of the J-7 is also intended to be used, and the J-8 in Shenyang is also going to be replaced with this engine, and everyone is looking forward to a power system with greater thrust.

The turbojet-13 has improved thrust compared to the original turbojet-7, and the engine continues to evolve, for example, the technologies that have been adopted include changing the steel casing of the 2 to 7 compressors to a cast titanium casing, which reduces the weight of the engine by 12.9 kg; The I. turbine blades were changed to hollow air-cooled blades, and the combustion chamber and afterburner were also improved. As a result of these improvements, the front turbo temperature of the engine was increased by 50 degrees, and the afterburner thrust of the engine was increased to 64.7 kN.

This is just a starting point, not the end, this plan of the F1 type is good, is on this basis, the first stage of the compressor is redesigned, and the casing of the compressor is equipped with surface layer control technology, further optimize the dune standing vortex flame stabilizer, in short, the work is more stable, the thrust is greater, the fuel consumption rate is also reduced, in foreign countries can not be seen, in the country is definitely a treasure.

For example, the current J-7 series fighters, after being equipped with this engine, are equipped with double delta wings and leading edge flaps, and it is easier to fight.

"We have a lot of projects to do now, and Super Seven involves a lot of energy, and we still have to improve the J-7, and then carry out the current project, which is really inadequate." Tu Lao sighed.

When Tu Lao finished speaking, Qin Feng suddenly thought of something, and couldn't help blurting out: "It would be good if we could join forces and form a company, our 611 Institute has the strongest scientific research strength, and our 132 factory has the most rich manufacturing experience, if we join forces, whether it is modifying the current aircraft or developing new fighters, it will be beneficial." ”

For example, the J-10 fighter is still being developed, if it is to be produced, then it needs to be allocated from Song Lao, and when it comes to the account of the 132 factory, the 132 factory will start to build, so there are undoubtedly a lot of twists and turns, if it is a company, it will be good.

In fact, in foreign countries, mergers and alliances between aviation groups have been very common, such as the unknown McDonald Company merged with the aviation giant Douglas and became McDonnell Douglas, which was talked about, and later, there were more alliances between various military enterprises, such as Lockheed and Martin, such as Northrop and Grumman, etc., they all needed to be together to be able to keep warm, and even McDonnell Douglas was finally merged by Boeing.

There is also a reason for this, because with the development of technology, researching a new aircraft, which costs more and more, is no longer something that one company can solve.

And now, Qin Feng first put forward this idea, one of the biggest benefits, is that 611 has been facing the problem of shortage of funds in the process of developing new J-1, and the profitability of the 132 factory is quite good, if the profit of the 132 factory is used to develop the J-10, isn't it a double win?
