"It doesn't matter who the commander of the Blue Army is, no matter who it is, as long as he can't pee in a pot with himself, he won't bother to care about the Blue Army. Equipment or something, let the military bosses worry about it" Since there is no way to know who the commander of the blue army is, he doesn't even know what the military is going to give Liu Yijiu, so he didn't bother to think about these problems immediately.

He returned to Rongcheng directly, and then took the Zhi 91 sent by the base back to the Dabashan base.

Liu Yijiu needed to arrange a lot of things, especially this transaction with the Soviet Union, which had to organize the supply of goods for trading, and had to train pilots to at least allow the Tu-22 to take off and land smoothly.

As long as you can fly, land down, and fly all the way back from the north, that's it, and then slowly explore it slowly, after all, the weapon system and everything need to be modified, and even the hydraulic system for auxiliary operation has to be modified.

These things can only be said later.

"This deal is like this, we got the technology for the production of medium-range air-to-air missiles R77 from the Soviets, and they gave us not active radar guidance technology, but semi-active radar guidance technology, and missiles with this guidance technology, even with a range of ninety kilometers, are difficult to use in the Air Force. It even needs to be launched at a distance of 20 kilometers, or even closer, such a missile" Liu Yijiu returned to the base of the Ninth Academy, and even Li Rui did not have time to see it. A meeting was held directly.

When he was in Rongcheng, he had already called Guò to arrange a meeting in the base. By the time we arrived, all the people in the base who had attended the meeting were already in place.

After giving a briefing on the current negotiations with the Soviet Union, Liu Yijiu focused on the missile project.

"Xiao Liu, this time such a huge CNC machining center, especially the five axes, pay thirty units at a time. It will have to be in half a year. This is a very huge pressure on our plan," Xie Heping heard Liu Yijiu ask them to do their best to provide an additional 30 five-axis CNC machining centers in half a year, which was very difficult for them.

The machinery manufacturing of the third district undertakes most of the high-precision and cutting-edge machinery manufacturing tasks of the entire Ninth Academy.

It is even responsible for the manufacturing of the core components of the turbofan 8, as well as the manufacturing of key components of the imitation of the F14 Panda J-10, such as the hydraulic system and so on.

Many managers in the third district have been asking the base to transfer the assembly technology of the five-axis CNC machining center to Hongshan Machinery Factory, and the managers of Hongshan Machinery Factory also hope to obtain the manufacturing technology of the five-axis machining center and further expand the production scale of Hongshan Machinery Factory. As a result, Liu Yijiu did not agree at all.

Most of the spare parts are outsourced by Hongshan Machinery Factory and the North Industries Group, which has business dealings with the Ninth Academy Base, and the relevant machinery manufacturing plants of the Aerospace 002 Base, and the production and assembly of core components are responsible for the three districts.

"Our own five-axis machining centers for these production units are not enough, NORINCO Group. Aerospace 002 Base, Shen Fei, Qin Fei, the Ministry of Aerospace Industry, etc., are all urging us to increase the production of five-axis machining centers" Xie Heping frowned when he saw Liu Yijiu, and he had to put the difficulties out.

For him, it doesn't matter if Liu Yijiu thinks he can't take on such a responsibility.

Unless Zone 3 is allowed to continue to expand production.

The question is. The scale of production in the three districts has been constantly expanding, but it is simply unable to meet their growing business, and the mountain can no longer afford the construction of a larger factory area unless the mountain is dug up.

"The problem is to save zài, but this time the 30 five-axis CNC machining centers must be provided within half a year, and within three months, at least six will be required. Our country does not have advanced strategic bombers, and we cannot devote our energy to strategic bombers now, so let's discuss the solution to this matter, and for now we will talk about air-to-air missiles." Liu Yijiu will feel in a bad mood as soon as he returns to the base.

Because no matter how the base expands, it is faced with a problem that the technology is not advanced enough, the equipment is not enough, and the personnel are not enough

"As for the progress of the Houyi-3 missile to a short-range air-to-air missile, the Iranians have urged it many times. Also, how is the imitation of the Immortal Bird long-range air-to-air missile going Now the imitation F14 has made its first successful flight, the second prototype has also begun to fly test, and the other two are being assembled.

The pressure is huge.

Domestic missiles with advanced performance, especially air-to-air missiles, are simply not good.

Otherwise, Iran would not have urged Liu Yijiu to ask Houyi to change to air-to-air missiles.

"Director Liu, we have no previous experience in the conversion of surface-to-air missiles into air-to-air missiles, especially the missiles are required to have better performance, and you require the missiles to fly at a minimum speed of Mach 3, which requires the design of new engines; At the same time, we also need to make the missile have stronger maneuverability and more sensitive reaction ability when it is in the air," Du Zhongkun felt a little big.

He was in charge of the missile projects of the Ninth Academy.

It stands to reason that every project should have a project leader, but Liu Yijiu doesn't do that at all.

Anti-armor missiles, anti-aircraft missiles, and even air-to-air missiles are all studied by a project team.

Although this can be coordinated and avoid waste, it is very difficult for him.

"I only ask about the progress, how long it will take to complete, and what is the reason for not being able to complete it" Liu Yijiu said with a frown, "As a project leader, I think you should know that not everything has to be done by you."

Everything should be focused.

Since the project of cooperating with the Aerospace 002 base to transform the Hongqi-2 anti-aircraft missile into a surface-to-surface missile 8208 missile, these guys have been focusing on missiles with a longer range.

However, the longer-range missiles and rocket artillery were all personally in charge of Wang Shunyi.

"The main thing is the engine, our engine is always prone to problems, and there is also the guidance aspect" Du Zhongkun was counted down by Liu Yijiu, and he was not dissatisfied, but introduced the difficulties of the whole project to Liu Yijiu.

Although the range of small missiles is short, the requirements are also sufficient.

Air-to-air missiles are even much more complex than surface-to-surface missiles and surface-to-air missiles. The reason for this is that the initial velocity of air-to-air missiles in the initial stage of launch is much higher than that of ground-to-ground and surface-to-air missiles. This requires air-to-air missiles to have a stronger ability to bear loads, and at the same time, it is also required that the missiles can have more flexible maneuverability to chase fighters.

"Is there a problem with the strength of the structure?" asked Liu Yijiu with a frown.

"At present, the main thing is guidance, if the speed of the missile reaches Mach 3, the infrared detection device will be weakened by the friction between the infrared head at the tip and the air, and as for the active radar, the small missile cannot be installed at all" short-range air-to-air missiles with a range of only about ten kilometers cannot use active radar guidance at all.

"In this way, it is not only the missile's guidance system that affects the guidance, but also the outer heat insulation coating," Liu Yijiu asked with a frown.

"Yes."

"Have you ever tried a heat-insulating coating based on materials such as silicone resin and hollow silica particles?"

Thermal insulation coatings are a big problem.

Hollow silica and silicone resin are composite heat-resistant materials that incorporate other lightweight heat-resistant materials, which is specially developed for the Double Three Project.

Of course, this is the coating material used by several major international powers on strategic missiles in the early days, which Liu Yijiu extracted from his memory.

"I have tried, although the effect is very good, but it will affect the reception signal of the infrared detection device, the speed is too high, and it will be affected by the air friction generated by the high speed of the missile" This is a very headache.

It's been such a long time, I don't know how many times the test has been done, and the technology of the Ninth Academy in infrared detection is even more than that of many countries in the world.

"Okay, let's discuss this matter later, what is the problem of the engine, the material processing and manufacturing process is still a design problem" Liu Yijiu's head is big.

Why is it so difficult to get a short-range air-to-air missile with a high speed

But now he somewhat understands why infrared-guided air-to-air missiles rarely exceed Mach 3.

It's not that countries don't want to make it stronger, it's that they're limited in that regard.

The higher the speed, the other way of guidance will have to be used.

Of course, after the satellite system, there is also a two-way digital chain, but now it is a bit early to get that technology. It's like learning to run before you know how to walk.

"There is no problem with the design, mainly in the processing and manufacturing of materials," Xie Heping said directly. "At present, the three districts are stepping up their efforts to tackle this aspect"

"What about AI imitation work, how is the research work of the active guidance radar of the Americans?"

Huang Qingyu said with some embarrassment, "There is not much progress, and the main energy is on the improvement of pulse Doppler radar."

Faced with such a complicated situation, Liu Yijiu suddenly had only one feeling and asked Cangtian speechlessly.

It seems that his task is to constantly organize and tackle key problems, tackle key problems, and then tackle key problems
