Chapter 912 Verification passed
Sure enough, when Chen Haiyang said that Zhang Qihang was worried that the comrades in the military industry might jump out and "cut off the barbarians", Tang Changhao immediately realized the seriousness of the problem: this kind of situation could happen again.

How can this work?

This thing was produced by our enterprises in Lu Province with great painstaking efforts. Why did you take it away?How big is the face?
Tang Changhao immediately said: "Xiao Zhang's worry is very reasonable, Xiao Chen, next you must be vigilant at all times, if this situation really happens, you must fight hard, if you argue hard and they still refuse to give up, Report to me immediately, do you understand?"

He asked for his ideas in his heart, and then he told Comrade Su Weimin about this matter later, and won Su Weimin's support——based on the status of himself and Su Weimin in the party and the system, once the two of them clearly expressed their opposition, no matter who wanted to If you want to grab something from Huateng Group, you have to weigh it first.

With Tang Changhao's support, Chen Haiyang's waist stiffened immediately, and he immediately said loudly: "Yes, please rest assured, the leader, I will never let anyone snatch this technology from our hands."

"now it's right……"

Tang Changhao was very satisfied with Chen Haiyang's statement.

Only Comrade Sun was dumbfounded watching: Comrades in Lu Province, have already begun to guard against their technology being snatched away?
However, Comrade Sun also had to admit that the worries of Chen Haiyang and even Zhang Qihang were indeed very reasonable. Based on his understanding of Liming Factory, Xifei Engine Factory and other old aero-engine manufacturers, they can really do this kind of thing. , but now... Seeing Lu Province put on such a posture of "fire, theft, and XXX", Comrade Sun suddenly felt a little gloating in his heart: I really look forward to seeing that day, I don't know what it will be like at that time. What a lively scene...

....................................

Looking back, let's talk about the above reaction!

在刘专家和孙同志将这里的情况汇报上去之后，空军的相关领导立刻就坐不住了：原本要做D-30K涡扇发动机大修业务的华腾工业集团，竟然在D-30KP-2涡扇发动机的基础上搞出了一个全新的改进版本？而且新版本的发动机在推力、油耗水平、噪音水平、整体寿命以及大修周期方面性能方面全面超越了D-30KP-2？

How can this be?

The unbelievable leaders repeatedly asked and confirmed, and finally figured out what was going on: it turned out that Mr. Sergei Izotov of Huateng Industrial Group had previously assisted the general manager of the D-30KP-2 engine. The designer, Mr. Pavel Alexandrovich Solovyev, the chief designer of the Soloviev Design Bureau, has worked on the design of the D-30KP-2. I am very familiar with it, and I have imagined what to do if I want to upgrade and improve D-30KP-2 in my spare time...

In fact, it can be said that Mr. Sergei Izotov has already had an improvement plan for the D-30KP-2 turbofan engine, but he has never had the opportunity to implement and verify it. This time is also a coincidence, Hua Teng After the industrial group undertook the overhaul work of the D-30K series aero-engines in China, Mr. Sergei Izotov knew that Zhang Qihang had the idea of ​​"learning overhaul first, then imitating, and then improving", so he directly put his previous The imaginary improvement plan was taken out, and the original plan was re-optimized with the help of Huateng Industrial Group's powerful computer resources...

That's it!

The leaders who figured out what was going on suddenly realized: If this is the case, then it makes sense, and all I can say is that all this is really a coincidence.

What excited the leaders the most was what the comrades of the 57XX factory put forward in the report about "Comrade Zhang Qihang believes that this engine is fully capable of replacing the turbojet-6 engine carried by the H8 aircraft, and once the replacement is successful, it can be greatly improved. Improve the range and load of the H6 aircraft": Is this okay?This is directly related to combat effectiveness!

Excited leaders immediately asked the experts of Xifei to understand the feasibility of this idea.

It doesn't matter if you don't understand, this understanding, the relevant leaders of the Air Force are so excited that they almost waver...

涡喷-8的最大推力只有93千牛，而D-30KP-3的最大推力则高达135千牛；

涡喷-8的最大直径是1400mm，而华腾工业集团的这款“D-30KP-3”发动机的最大直径1662毫米，大的有限；
涡喷-8的自重是3100公斤，华腾工业集团的这款“D-30KP-3”的重量只有2662公斤，比涡喷-8还轻了400多公斤，
The only difference is in the length of the engine, the Huateng Industrial Group's "D-30KP-3" engine is longer than the turbojet-8, which means that if the H6 is replaced with this engine, it needs to be reinstalled. Calculate the center of gravity of the aircraft.

But this is not a problem at all. Previously, XAC was discussing with the Air Force the possibility of developing the third-generation H30 aircraft (that is, the future 2K) based on the D-6KP-6 turbofan engine. The D-30KP-2 There are many differences between the engine and the turbojet-8 in many aspects such as diameter, center of gravity, air intake, and fixed support points of the fuselage, which need to be redesigned and calculated. Compared with the D-30KP-2, Huateng Industrial Group's Although the diameter of the "D-30KP-3" is slightly larger, the workload is still the same, even if it is more, it is limited.

But compared to D-30KP-2, Huateng Group's "D-30KP-3" has greater thrust, lower fuel consumption, and longer overhaul cycle and service life. To put it bluntly, if Huateng Industry can The "D-30KP-3" of the group has developed a new generation of H6 aircraft. The performance of this aircraft is better than that of the "virtual aircraft" based on D-30KP-2 provided by XAC, and it has a higher ammunition load. Larger and longer range, it is a better choice!

And for a bomber, what does a larger bomb load and longer range mean?
It means that the core technical indicators have jumped!
Therefore, the XAC comrades are very excited.

Comrades from XAC were very excited, and comrades from the Air Force were also very excited. They immediately ordered to transfer personnel from relevant units to evaluate the technical solution of this "D-30KP-3" of Huateng Industrial Group.

As we said before, this evaluation is only a preliminary evaluation, and it will not take long. It is just to see if there are obvious defects and deficiencies in the "D-30KP-3" aero-engine improvement plan of Huateng Industrial Group. Therefore, the entire evaluation process was very fast. It only took about a week. The expert team in the field of aero-engines organized by the Air Force (including several experts from the 57XX factory) completed the preliminary design of the "D-30KP-3" program. Evaluation, the experts agreed that the "D-30KP-3" program has no obvious problems and deficiencies.

"There are no obvious problems and deficiencies?" The leader who received the report asked immediately: "What deficiencies did you find in 'there is no obvious deficiencies'?"

"Cough cough..."

On the phone, Li Weihong, the person in charge of the evaluation team, coughed twice: Why is the leader so inconsiderate of the difficulties of his subordinates?What I'm saying is that I didn't find any deficiencies.But complaints belong to complaints, and he said honestly: "Leader, because it is only a preliminary review, we have not found any problems or deficiencies."

"No problem found..."

The leader froze for a moment, touched the sentence carefully, and then asked in disbelief: "You mean, you didn't find any problems with this plan of Huateng Industrial Group?"

From the perspective of leaders, how is this possible?No matter how perfect the "D-30KP-3" improvement plan of Huateng Industrial Group is, there are still no problems at all, right?
Comrade Li Weihong also felt a little embarrassed. If he didn't find a problem, would it make the leader feel that he was not capable enough?But there is no way, if no problem is found, then there is no problem found, and there is no lack of nitpicking when reviewing the plan, but it is useless at all. In front of Mr. Sergei Izotov, people like myself are naive and have nothing to do with a child the difference.

He had to bite the bullet and explained: "Leader, we asked Mr. Sergey Izotov on the spot for all the questions we found, and Sergey Izotov also gave reasonable answers. The results are also reasonable, so we draw the conclusion that:
The reason for this result is that Mr. Sergei Izotov is no less familiar with this engine than its designer. In addition, he has polished this quick plan for several years, so this The plan is actually a very mature and perfect plan. "

Speaking of this, Li Weihong hesitated for a while, and added: "I think it is our luck to have such a result."

"..."

The leader was speechless.

But after thinking about it carefully, the leader also felt that Comrade Li Weihong was right. Isn't such a result our luck?

Thinking of this, he felt a lot more comfortable: Isn't that the case? After all, Mr. Sergei Izotov is the second chief designer of the Klimov Design Bureau, even in the world. Isn't it normal for a top aero engine master to design such a complete improvement plan?It can only be said that the big brother is the big brother, and the background is profound. Even an old expert like Sergey Izotov, who has retired for more than ten years, still stands out from the crowd when he comes to China. .

Li Weihong then asked: "Leader, then you see, shall we wait at the Huateng Group, or come back for the time being?"

According to the process, since the "first trial" is okay, then the "second trial" will be carried out next, and for the second trial, the Aviation Industry Corporation must be invited to organize "elite soldiers and strong generals", and this work is already done. It was not in the original plan, and if we want to transfer people to participate in this review, we need to coordinate with many parties.Thinking of this, the leader pondered for a moment and said, "It will take some time for the review team to prepare, so you guys should come back first."

Li Weihong quickly responded: Finally, I can go back.

To be honest, staying in Huateng Group during this period of time made everyone even doubt the actual level of the domestic aero-engine industry, and they had to go back and adjust their mood.

-------------

The expert team went back, and Zhang Qihang was not in a hurry. He knew very well that this kind of thing had to go through a process, and it was useless to be impatient, just wait slowly.

But what Zhang Qihang didn't expect was that just after the experts of the review team left the group, his old friend, Comrade He Jiacheng from Hongdu Factory, actually called. After a few simple greetings, he asked Zhang Qihang : "Mr. Zhang, I would like to ask, how is the progress of the DV-2 engine developed by your group?"

"It's going well. After all, is it a mature engine? According to the current progress, it is estimated that in another 9 months to a year, we should be able to obtain the airworthiness certificate and production certificate," Zhang Qihang joked. He said, "What? Why is Hongdu factory still planning to purchase this engine from us?"

Zhang Qihang's words are mostly a joke. After all, the main product of Hongdu Factory: the engine on the K-8 trainer is Ermao's AI-25TL turbofan engine, and even our country has just equipped it. The JL-8 jet trainer developed on the basis of the -11 is currently equipped with this engine. In this case, how can Hongdu Factory purchase the DV-2 of Huateng Industrial Group? Engines in the stage of airworthiness certification?

But what Zhang Qihang didn't expect was that when faced with his own joke, He Jiacheng actually responded: "I really made you guess, Mr. Zhang, to tell you the truth, I am calling you to seek advice from your unit. DV-2 engine support."

"what?"

This time, Zhang Qihang was really surprised. After being taken aback for a while, he frowned and said, "Mr. He, are you serious?"

"I'm sure I can't joke with you on such a big matter..." Speaking of this, He Jiacheng paused, and explained: "Well, that's the case, Mr. Zhang, our group's K-8 participated in this year's Turkish-Egyptian air force competition. You should have heard of the trainer aircraft bidding activity, right?"

The K-8 trainer aircraft of Hongdu Factory participated in the training aircraft bidding activity of the Turkish Air Force?
Of course, Zhang Qihang is no stranger to this matter. He nodded and said, "Yes, I have read relevant reports in the media. So you have received the final order? Congratulations."

In fact, Zhang Qihang has never read this report, but it doesn’t matter if he hasn’t. K-8 is a rare product in the field of domestic military aircraft, or it is the only product that shines on the international arms sales stage. As a military fan, Zhang Qihang is also familiar with this aircraft and the resume of this aircraft and cannot be more familiar:
Originally, the K-8 was an aircraft that my grandma didn’t care about and my uncle didn’t love. Even our own air force didn’t like it. It can be regarded as bringing the dead back to life.

After being brought back to life, the K-8 became more and more courageous in the international arena. In 96, when it was learned that the Air Force Academy of Turkey and Egypt was going to upgrade its own trainer aircraft, the Hongdu factory immediately approached the door and recommended itself.

At that time, several models such as the Italian S211 and the Czech L-139 were interested in competing for the military trainer order from Turkey and Egypt. The opponents faced by the K-8 trainer were all mature models that had been widely recognized internationally, and no one was optimistic about them. K-8, but K-8 is in this kind of situation that no one is optimistic about. It has overcome all obstacles and has the last laugh. It has successfully won the order of 80 jet trainers in Turkey. This is the first time in our country. Export aircraft production lines and design technologies to foreign countries.

Not only that, after completing the order of 80 K-8E trainer aircraft in the contract, Tuai signed a purchase contract with Hongdu Factory for 40 K-8E trainer aircraft, which also created my country's single military aircraft product. export records.

But now, counting the time, it is almost exactly the time when Hongdu Factory signed a purchase contract with Tuai for 80 K-8E trainer aircraft.

"Hehehe..." He Jiacheng smiled happily. After all, this matter is indeed something to be proud of: "It's almost time, it should be a recent incident, but Mr. Zhang, I called you today for the sake of The DV-2 engine from your factory came."

Hearing this, Zhang Qihang couldn't help frowning.

The K-8 trainer is now equipped with three engines, one is Ermao's AI-25TL, which is also the engine with the largest installed capacity of the K-8, followed by the domestic turbofan-11 and the American TFE731, but this For a while, the turbofan-11 has not yet been finalized, and the TFE731 is not only expensive, but also requires expensive foreign exchange, so the entire Hongdu factory did not purchase a few units, so the AI-25TL engine is the main use of the K-8 trainer Engine, but now, He Jiacheng actually said that he would purchase a DV-2 engine from Huateng Group?
Zhang Qihang was a little confused: what is the situation?
Zhang Qihang, who couldn't figure it out, simply said to He Jiacheng: "Mr. He, if you have something to say, just speak up."

"Okay, given the relationship between our two units, I won't go around in circles with Mr. Zhang," He Jiacheng said, "That's the thing. There were two demonstration prototypes provided by the Czech Republic to the Turkish and Egyptian Air Forces, one equipped with a TFE731 The L-139 engine, the other is the L-2 equipped with a Ukrainian DV-59 engine.

According to the Czech side, the L-2 trainer aircraft with DV-59 engine has stronger power and greater thrust, so in addition to being used as a trainer aircraft, it can also be used as an entry-level light fighter or attack aircraft. As a result, this aircraft can not only be used for daily flight training, but also perform routine patrol missions, and even conduct some low-intensity air combat if necessary.

The Turkish and Egyptian side was very interested in this proposal, so they told us this statement and asked if it is possible for us to develop such an entry-level light trainer/attack aircraft?
After thinking about it, our comrades think that the DV-2 engine is an improved and upgraded version of the AI-25TL engine. Since the DV-2 engine produced by your Huateng Group has entered the stage of airworthiness certification, if our Hongdu factory uses it Based on your DV-2 engine, is it possible to create a light trainer/attack aircraft based on the K-8?But in this case, we need the cooperation of our unit..."

That's what happened...

Zhang Qihang nodded, and finally figured out what was going on, but he was also a little curious: "This idea is good, but Mr. He, in this way, the overall cost will go up, and our engine will still be expensive after all. If the airworthiness permit and production permit have not been obtained, will the Turkish and Egyptian side have any objections?"

After all, he didn't have the nerve to say it too directly: the reason why Tuai gave the order to your Hongdu factory is not because your K-8 trainer aircraft is "high quality and low price". If you do this, the K-8 Are jet trainers still cost-effective?

"Of course we have considered this issue." He Jiacheng laughed when Zhang Qihang said this issue: "Although your DV-2 engine has not yet obtained an airworthiness certificate, you are from the Ermao family. You have obtained the technical authorization of the DV-2 engine, and the DV-2 has obtained airworthiness certificates in the CIS countries and the Czech Republic, indicating that the design and maturity of this engine have been fully verified. Your side It's just going through the airworthiness process.

We notified this situation to the Turkish and Egyptian side, and the Turkish and Egyptian side also recognized our statement. Of course, considering that airworthiness certification is necessary, the aircraft delivered in the early stage can be the basic type, that is, the trainer type. Wait for your DV- 2 The entry-level coach/attack type will only be delivered after the engine has obtained the airworthiness certificate. "

Your little calculations are really good...

However, the Hongdu factory was able to persuade the local and Egyptian side to approve this plan, and their business personnel are really strong enough.

With emotion in his heart, Zhang Qihang said: "If this is the case, then there is no problem... So, the Tuai side added an additional batch of orders for this 'entry-level trainer/attack aircraft' in addition to the previous orders? "

"Uh... That's not true. The total amount of orders is still the same. The Turkish and Egyptian side is planning to upgrade some of the aircraft to new versions, about 20 or so."

"I understand……"

After pondering for a while, Zhang Qihang said: "Mr. He, to tell you the truth, your situation is really sudden, and I really don't have any mental preparations here, but anyway, this is a good thing for a year after all... so, in this way, I can't understand it on the phone. You or you can send someone to our unit, or our group can send someone to your Hongdu factory. Let's sit together and discuss how to do this cooperation. What do you think? "

"" What He Jiacheng was waiting for was Zhang Qihang's words, and he immediately said: "This is what I meant to call you. If Mr. Zhang doesn't mind, let us arrange someone to visit you. I heard that we The group has come up with a very powerful aero engine, just in time, let's take a look at your new engine by the way."

华腾工业集团在伊尔-76运输机上面搭载的那台D-30KP-2发动机的基础上，搞出了一个叫“D-30KP-3”的改进方案，据说相比于D-30KP-2，华腾集团的这个“D-30KP-3”方案d 最大推力提升了10千牛左右，油耗也降低了不少……

This news has spread throughout the domestic military system, especially the aviation system. Some people scoff at this rumor, thinking that Huateng Group is sensationalizing, and some people are dubious, but no matter whether they think Huateng Industrial Group is grandstanding or are dubious, They all thought it was nonsense.

He Jiacheng belongs to the dubious group, but even so, he still finds it unbelievable: Your Huateng Group can not only imitate such a powerful turbofan engine as D-30KP-2, but even come up with an improvement plan, and its performance is still good. Improved so much?Why does this sound so outrageous?
