After reaching an agreement with Ma Liping on the technical route, Chang Haonan took the entire foundry research team to devote himself to a new round of technology research and development.

On the other hand, the problems of the device should also be solved synchronously.

This is precisely the reason why the former has been entangled for so long.

After all, it's a new device that I just bought back for a short time, and I just replaced it directly, which is really a bit of a loser.

However, the two people analyzed it later and found that although the two processes are very different in terms of control methods, the basic principles are very similar, so the difference in hardware is not so big.

It is completely possible to make in-situ improvements on the basis of the original equipment.

finally made Ma Liping breathe a sigh of relief.

As the director of this precision casting center, although he does not carry KPIs at the financial level, as the leader of a research institution, he must always be more careful.

Therefore, Chang Haonan contacted Shengjing Scientific Instrument Company, which is also a subsidiary of the Chinese Academy of Sciences, through the Torch Group, and asked the other party to improve the solidification equipment of the directional solidification furnace according to the requirements, and change the original high-speed solidification process to the liquid metal cooling process that has been patented by him.

Of course, the Dawn Factory has these on hand, as well as the patent licensing fees for the newly purchased equipment in the future, must be exempted.

But if there are other users, the two companies will add two to five, and the profits will be directly divided equally.

It was an inconspicuous but far-reaching collaboration.

In addition, software upgrades still require support at the hardware level.

Compared with the high-speed solidification method in which the cold end is in a complete vacuum state, the new process has a much higher control accuracy for the temperature field of the cold end than before, and the specific heat capacity of both liquid tin and liquid aluminum is quite huge, and more effective induction heating power supply, stirring system and temperature sensor are also required......

Fortunately, in the past two years, the industrial level of Huaxia has been pushed by Chang Haonan in several waves, and it has indeed made great progress, most of the parts can be obtained in China, such as sensors, which are more sophisticated, and because of the cooperative relationship with Europe, it is not difficult to bypass the technical blockade that has basically existed in name only, and buy relatively high precision.

It's just that this process definitely needs a process.

Gotta wait.

As for the model design of the investment casting process mentioned earlier, Chang Haonan has already built the shelf, but he still needs enough data to adjust various parameters.

Therefore, after deciding on the specific research plan for the manufacture of monocrystalline turbine blades and arranging the work, he himself was not as busy as the first few days.

But on the other hand, it was also because he had to adjust the parameters according to the data of the casting process, and then feed back to the production side for new process testing, and he could not temporarily leave Shengjing as usual to focus on other projects.

In short, it is unprecedentedly idle.

Of course, in terms of Chang Haonan's current status, the so-called "idle" can only be relative.

After all, Shengjing is the cradle of China's military industry, especially the aviation industry, and has a large number of research institutes and enterprises belonging to the system of the Commission of Science and Technology.

Such a great god is right next to him, and he doesn't seem to be very busy.

Such a godsend, I must try to invite it.

Even if you can't invite it, at least you can show respect for the big guy.

The meaning has to be in place.

Chang Haonan is not a person who likes pomp and circumstance, so he refuses most of the invitations that have no nutrition and just invite him to have a look or give a lecture.

However, Shengjing is also his starting place after all, so some places are still worth visiting.

For example, 112 factories and 601 factories.

First, he has a lot of acquaintances in these two places, and second, what are the ......

He also wanted to see for himself what the Persian F14 was like -

Unlike the previous F4EC project, because the F14 has too many places to move, and the number of aircraft that needs to be upgraded is relatively small, only 40 aircraft, so at least a significant part of the life extension upgrade project needs to be carried out in Plant 112, not in Persia.

To this end, Shengjing Aircraft Industry Group also set aside a space in the assembly workshop of the old J-8 to park the three planes that were first sent to Huaxia.

For Factory 112, Chang Haonan is already an old regular, so there is no big pomp.

It's just that the director and secretary of the factory took the leadership team to the factory gate to greet a wave.

Then He Ming, an old acquaintance who has now been promoted to the chief engineer of Shengfei Group, took Chang Haonan to change his tooling and came to the assembly workshop that the latter was familiar with.

Compared with the J-11, although the production of the J-8 series now uses some new technologies such as digital mapping, it does not introduce the pulsating production idea of parallel operation and collaborative assembly, and still uses the traditional assembly method.

It's slower, but it's a good time.

Because there are almost no requirements for the layout of the site, it is easy to divert a part of the area for other uses.

"These are the three planes that the Persians sent."

He Ming took Chang Haonan past two J-8B/D that were in different assembly progresses.

This is a previous order placed by the Air Force, which has not yet been fully delivered.

When they began to cut production, they were still the latest domestic fighters in China.

Who would have thought that just two years later, Britney would have become Mrs. Niu.

……

The two of them came to the other side of the factory, which was separated by a fence.

Three F14As painted in desert camouflage are parked here.

However, only one of them is intact, and the other two have been stripped of their iconic swept wings and vertical tail.

"This is one of the 4 planes that Persia gave us directly in exchange for in the contract, and the above means that it will be overhauled a little, and then handed over to the Blue Army Brigade on the Dingxin side to form a high-simulation vacation enemy unit similar to the 65th Squadron of the US Army."

He Ming walked to the side of the plane and introduced to Chang Haonan.

The latter took two steps forward and reached out to touch the F14, which was still painted with the Persian Air Force insignia, especially the variable wing.

For various reasons, the Huaxia aviation industry completely missed this wave of variable swept wing from the 60s to the 80s.

There are a number of models that were originally planned to use this configuration, but either abandoned due to technical or cost issues, or the entire project was simply aborted.

Although from an afterthought, this cannot be considered a bad thing.

But purely from the perspective of hobbies and feelings, it's still a bit of a pity.

In his previous life, Chang Haonan had never even been able to see an aircraft with a variable swept wing structure up close.

Now it's a small wish.

"This idea is good, but it's a pity that the F14 on the US side's side is estimated to be retired soon."

Chang Haonan's tone was slightly regretful.

It's not because of the retirement of the F14 itself, but because I finally got a few active US military aircraft that can fly, but the actual combat value of the training has been greatly reduced.

He Ming's mentality is much better:

"There is no way, the reliability and dead weight problems of the variable sweep wing are brought out of the womb, and the scheduling of the F14 on the deck of the aircraft carrier is not as convenient as that of the F18, and the real sortie rate is very different."

"On the bright side, it's hard to start with everything, and maybe you can get other models in the future."

He just said it casually now, but he inadvertently reminded Chang Haonan.

If memory serves, there should indeed be a batch of F16A/B fighters from the early 80s on the Venezuelan side......

But that's all for later.

After seeing the complete plane that had been assembled, He Ming took Chang Haonan to a place slightly closer to the door.

The other two planes have been dismantled and shattered, and there are quite a few technicians working around.

A considerable number of them are obviously not Chinese faces.

"Those are the Persians?"

Chang Haonan raised his hand and gestured.

There is almost nothing in this workshop, even if there are foreigners.

"No, it's the Russians, from the Pennant Design Bureau, who came over and was responsible for integrating the R33 missiles into those planes."

"They have developed a new generation of R37 ultra-long-range air-to-air bombs two years ago, so they don't care too much about R33, and they just brought a few sample bombs."

While speaking, He Ming took Chang Haonan around the two planes and came to the other side of the factory.

On top of the special carriage here are two missiles that are extremely large for air-to-air weapons.

Chang Haonan roughly estimated it, and was very sure that this thing was thicker than his waist......

"How heavy does this thing ......?"

He whispered to He Ming next to him.

"The bomb itself weighs half a ton, has a charge of about 40 kilograms, and has a theoretical range of 300 kilometers, but it needs to cooperate with the MiG-31 radar to achieve ......"

However, Chang Haonan didn't care about the second half of He Ming's sentence.

He thought for a moment, then looked up again:

"I think this kind of thing should have other potential......

"Anything else?"

He Ming didn't react much for a while.

"When I was working on the Thunderbolt 11 before, I suggested that the Second Electromechanical Bureau should build an anti-radiation missile on that basis, but later I found that the volume was too small, and the range and power were not enough for both air and ground."

Chang Haonan pointed to the two R33s in front of him:

"If there is something of this volume, I'm afraid it will be much more convenient......"
