The Military-industrial Scientific Research System of the Academic Master Chapter 581

Chapter 581 What a big missile! (Please ask for a monthly pass at the beginning of the month~)

After reaching agreement on the technical route with Ma Liping, Chang Haonan led the entire casting research team into a new round of technology research and development.

 On the other hand, equipment problems must also be solved simultaneously.

 The reason why the former has been struggling for so long just now is precisely for this reason.

  After all, it was a new device that I had just bought, so it was a bit of a waste to just replace it.

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

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

Ma Liping finally breathed a sigh of relief.

As the director of this precision casting center, although he does not carry financial KPIs, as the head of a research institution, he must always be careful with calculations.

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 as required and change the original high-speed solidification process to one that he had registered. Patented liquid metal cooling process.

 So, after determining the specific research plan for manufacturing single-crystal turbine blades and arranging the work, he himself was not as busy as he was in the first few days.

Such a God-given opportunity, I must try to invite it.

Even if you can't invite him, you can at least show respect to the boss.

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

Of course, the patent licensing fees for these things that Liming Factory has on hand, as well as the subsequent new equipment purchased, will definitely be waived.

 In short, I am free for the first time in history.

 For example, 112 factories and 601 institutes.

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

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

However, Shengjing can be regarded as the place where he started, so there are some places worth visiting.

In addition, software upgrades still require hardware-level support.

Chang Haonan is not a person who likes ostentation, so he refuses most of the invitations that are not nutritious and just invite him to take a look or give a lecture.

 Have to wait.

 It can be regarded as a cooperation that is not very eye-catching, but has far-reaching impact.

As for the investment casting process model design mentioned above, Chang Haonan has already set up the framework, but still needs enough data to adjust various parameters.

  After all, Shengjing is the cradle of China's military industry in various senses, especially the aviation industry. There are a large number of research institutes and enterprises under the Committee of Science and Industry.

 The meaning must be in place.

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

Fortunately, China's industrial level has been pushed forward several times by Chang Haonan in the past two years. It has indeed made great progress. Most parts can be obtained domestically, and the more sophisticated ones such as sensors are not the same as those in Europe. With the cooperative relationship, it is not difficult to bypass the technical blockade that has basically existed in name only to buy one with higher accuracy.

Of course, considering Chang Haonan's current status, the so-called "leisure" can only be relative.

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

 First of all, he has quite a few acquaintances in these two places, and secondly...

 He also wanted to see with his own eyes what the Persian F14 was like—

It is different from the previous F4EC project. Since the F14 has too many places to move, and the number of aircraft that need to be upgraded is relatively small, only 40, at least a considerable part of the life extension upgrade project needs to be carried out in the 112 factory. Not in Persia.

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

 For Factory 112, Chang Haonan is already a regular visitor, so he doesn't make any grand arrangements.

It's just that the factory director and secretary took the leadership team to the factory gate to greet them in person.

 Then He Ming, an old acquaintance who has now been promoted to chief engineer of Shengfei Group, took Chang Haonan to change into work clothes and went to the assembly workshop that the latter was all too familiar with.

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

Although it is slower, it is actually beneficial at this time.

Since there are almost no requirements for site layout, it is enough to have a place to park the aircraft and assemble the frame. It is easy to divert part of the area for other uses.

“These are the three planes sent by the Persians.”

He Ming took Chang Haonan past two J-8B/Ds that were in different stages of final assembly.

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

 When they started cutting out materials for production, they were still the most cutting-edge domestically produced fighters in China.

Who would have thought that just two years later, Xiao Tiantian would have become Mrs. Niu.   …

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

There are three F14As in desert camouflage parked here.

However, only one of them is complete, and the other two have had their iconic swept wings and vertical tail removed.

"This complete aircraft is one of the four that Persia sent to us directly in exchange for the contract. It means that it will be slightly overhauled and then handed over to the Blue Army Brigade in Dingxin to form a force similar to the 65th Squadron of the US Army. Highly simulated imaginary enemy troops.”

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

The latter took two steps forward, stretched out his hand and touched the F14, which was still painted with the Persian Air Force emblem, especially the variable wing part.

 Due to various reasons, China Aviation Industry completely missed the variable sweep wing trend from the 1960s to the 1980s.

 There were many models that were originally planned to adopt this configuration, but were either ultimately abandoned due to technical or cost issues, or the entire project simply died halfway.

Although in hindsight, this can't be considered a bad thing.

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

In his last life, Chang Haonan was not even able to see an aircraft with a variable sweep wing structure up close.

 Now it can be considered that a small wish has been fulfilled.

“This is a good idea, but it's a pity that the F14 in the US military is about to be retired.”

Chang Haonan's tone was slightly regretful.

It's not because of the retirement of the F14 itself, but because we finally got a few U.S. military active-duty aircraft that can fly. As a result, the actual combat value of the training was greatly reduced.

He Ming's mentality is much better:

“There is no way. The reliability and dead weight issues of the variable sweep wing were brought up in the mother's womb, and the F14's dispatch on the aircraft carrier deck is not as convenient as the F18's, and the actual dispatch rate is very different.”

“Looking on the bright side, everything is difficult at the beginning. We may be able to get other models in the future.”

 He was just saying it casually now, but he accidentally reminded Chang Haonan.

If I remember correctly, Venezuela should indeed have a batch of F16A/B fighter jets from the early 1980s...

However, these are all things for later.

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

The other two planes have been dismantled into pieces, and there are still many technicians busy around.

 A considerable number of them are obviously not Chinese.

 “Are those Persians?”

Chang Haonan raised his hand to signal.

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

“No, it's the Russians from the Pennant Design Bureau who came over to be responsible for integrating the R33 missiles into those aircraft.”

“They have developed a newer generation of R37 ultrlong-range air-to-air ammunition in the past two years, so they don't care much about R33 and just brought a few sample rounds over.”

As he spoke, He Ming led Chang Haonan around the two planes and came to the other side of the factory.

On the special bracket here are two extremely large missiles in terms of air-to-air weapons.

Chang Haonan made a rough estimate and was very sure that this thing was thicker than his waist...

 “How heavy is this thing…”

 He asked in a low voice 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 be matched with the MiG-31 radar to achieve it..."

However, Chang Haonan didn't pay attention to the second half of He Ming's words.

 After thinking for a moment, he raised his head again:

 “I think this kind of thing should have potential in other aspects…”

"other aspects?"

He Ming didn't react much for a while.

"When we were working on Thunderbolt 11 before, I suggested that the Second Bureau of Electrical and Mechanical Engineering develop an anti-radiation missile based on that. However, I later found that the size was too small, and the range and power were not sufficient whether it was for air or ground purposes. ”

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

“If there was something of this size, it would be much more convenient...”
