Set sail1992

Chapter 774 Everything is going well

It wasn't until he stepped out of the hatch and stepped on the land of the motherland that Zhang Qihang let out a long breath, and finally put his heart back into his stomach.

To be honest, unlike the pure and beautiful yearning of most people in this era for Americans, Zhang Qihang is very aware of how Americans have no bottom line, although no American has come to him since this period of time, But he was not sure whether he was being targeted by the US intelligence agencies, and he was not sure whether these bottomless guys would do something crazy, so since he got on the plane, Zhang Qihang's heart has been mentioned throat.

But luckily, the plane landed safely at the Capital International Airport, and Zhang Qihang was not afraid when he arrived in China.

Seeing Zhang Qihang, the new driver, Duo Duo, and secretary Xia Xiaobin immediately beamed with joy, and quickly walked up to him: "Mr. Zhang..."

"You two, I'm just on a business trip for a while, as for?" Looking at the two people with red eye circles, Zhang Qihang was very happy, and asked Xia Xiaobin with a smile: "Xiao Xia, how is the situation of the group during this time?" ?”

While talking, Zhang Qihang casually handed over his luggage to Dou, and Dou took Zhang Qihang's luggage with a simple and honest face, and followed behind.

Xia Xiaobin, who knew very well that the reason why his boss Zhang didn't take him to Ukraine was to let him act as his eyes and ears in the group, quickly collected his mood, and seriously reported to Zhang Qihang: "The situation of the group is very good, you During the absence, everything in the group is developing step by step, and the technical team from the 'Progress' Machine Manufacturing Bureau has also been properly arranged, and they are very satisfied with the living and working conditions here. "

Speaking of this, Xia Xiaobin couldn't help showing a proud smile on his face.

Back then, when the comrades from the Ukrainian "Progressive" Machine Manufacturing Bureau just arrived, they all looked a bit over the top, but when Secretary Feng took them around in person, he saw the Huateng Industrial Group in the After scientific research and living conditions, all of these erratic boys from Ukraine disappeared. In the words of their team leader named Igor Yaroslavsky, it was "unbelievable! ".

For the "Progressive" Machine Manufacturing Bureau, which still uses a lot of manual drawing, they can't imagine that Huateng Industrial Group not only equips each designer with a latest "Pentium" computer, but also has mainframes, medium-sized Machine, so to speak, in terms of R&D hardware alone, Huateng Industrial Group is more than ten years ahead of the "Progress" Machine Manufacturing Bureau?

"As long as they are satisfied," Zhang Qihang expressed his satisfaction at the news. He nodded, and then asked, "Is the running-in between the Ukrainian technical team and our Russian technical team going smoothly?"

For the technical team sent by the Ukrainian "Progressive" Machine Manufacturing Bureau, Zhang Qihang has no plan to return it, especially the soon-to-retire team leader Igor Yaroslavsky, who is not only a member of the "Progressive" Machine Manufacturing Bureau. The executive deputy general manager of the Bureau, and the deputy chief engineer of the "Progress" Machine Manufacturing Bureau, was trained by the Soviet Union and is extremely rare in the aviation industry. Talents who understand both management and technology. In Zhang Qihang's view, let such a It's a pity for a talent to retire like this. He should stay in Huateng Industrial Group and continue to shine. The premise of all this is that the two teams have a good run-in.

"Very good," Xia Xiaobin immediately nodded and said, "Many of them are old friends who have known each other for many years. You didn't see the scene at that time. Many people hugged each other and started crying."

"That's good..."

For this result, Zhang Qihang expressed his satisfaction.

"By the way, Mr. Zhang, before we came, Secretary Feng specifically told us to let you go back to rest for two days and not rush back to the company..."

Before finishing speaking, Zhang Qihang interrupted: "Let's go back to the company first."

"what?"

Unexpectedly, Zhang Qihang would go back to the company first, Xia Xiaobin couldn't help being taken aback.

"Go back and see everyone first," Zhang Qihang said, "I'm resting tomorrow."

After Zhang Qihang said that, Xia Xiaobin and Duo naturally said nothing more.

………………

The car drove all the way and soon arrived at Langya City.

Back at the company, Zhang Qihang went around Feng Guoqing's office first.

Seeing Zhang Qihang, Feng Guoqing nodded Zhang Qihang twice, and said with a smile: "I knew you must come back first!"

Zhang Qihang laughed twice, and said: "Come back first and say hello to everyone, and I'll take a good rest later."

Feng Guoqing was not surprised by this. He knew Zhang Qihang's character too well. After slightly nodding his head, Feng Guoqing said: "You also know the situation of the group during this time. Everything is normal. In addition, these experts from Ukraine I also follow your The meaning is settled...Let's go, I'll go and have a look with you."

"Alright."

Everyone has been working together for such a long time, and Zhang Qihang is not polite to Feng Guoqing.

When I came to the technology research and development center, I saw that Igor Yaroslavsky was discussing something with Sergey Izotov. Seeing the two people discussing enthusiastically, Zhang Qihang was very happy and asked with a smile. He said: "Mr. Izotov, Mr. Yaroslavsky, what are you discussing? ... Well, sit down, sit down, don't need to get up."

Sergey Izotov and Igor Yaroslavsky were not polite to Zhang Qihang, saying: "We are discussing the feasibility of developing a turboprop engine based on the core engine of the DV-2 engine. "

"Oh?"

Zhang Qihang's eyes lit up when he heard the words, and he quickly asked, "Has there been any results from the discussion?"

Igor Yaroslavsky and Sergei Izotov couldn't help but look at Zhang Qihang strangely after hearing this: "Zhang, don't you know?"

Zhang Qihang was even more confused by this question: "What do I know?"

Sergey Izotov asked: "Do you know the famous TV3-117 series turboshaft engine?"

“当然，”张起航不假思索的点头：“这可是苏联应用最广的一款涡轮轴发动机，米-8、米-17、米-24以及卡-50……几乎在苏联的主力军用直升机上都能够看到这台发动机的身影，苏联甚至在TV3-117VMA上研发出了一款TV3-117VMA-SB2/M的涡轮螺旋桨发动机，被应用在了安东诺夫设计局现在正在研制的安-140支线客机上面……”

Speaking of this, Zhang Qihang suddenly realized, and said in surprise: "You mean..."

"That's right." Seeing Zhang Qihang who had finally reacted, Igor Yaroslavsky nodded with a complicated expression on his face, "The TV3-117 series turboshaft engines and turboprop generators are powered by AI. The -25TL turbofan engine was developed on the basis of the core engine. Simply put, the early TV3-117 turboshaft engine was developed on the basis of the AI-25TL engine core engine. The -25TL engine was improved, and there was DV-2, and then TV2-VMA series turboshaft and turboprop engines were developed on the basis of DV-3 core engine."

After Igor Yaroslavsky finished speaking, Sergei Izotov also looked at Zhang Qihang with a complicated face: "Zhang, Yaroslavsky told me before that you introduced DV-2 and D- The process of the 36 engine, I have to say, your luck is really good, no matter it is a few years earlier or a few years later, it is impossible to obtain the technology of these two engines from Ukraine in this legal way. "

"..."

Zhang Qihang was dumbfounded: Is it like this?
Although he is a military fan, he can only be regarded as an "amateur military fan" strictly speaking. When it comes to the parameters of military equipment in various countries, he can speak clearly and logically, but if it is specific to a certain aero engine or a certain aero engine He was blinded by the technical inheritance relationship, and now I heard Sergei Izotov and Igor Yaroslavsky talk about the DV-2 turbofan engine and TV3-117 series turboshaft/turboprop engine they introduced There is such a technical relationship between...

He couldn't control himself anymore, his heart began to jump involuntarily "bang bang bang...", took a deep breath, and Zhang Qihang said: "Does this mean that we also have the ability to recover in China?" The basis for engraving TV3-VMA series turboshaft engines and TV3-117VMA-SB2/M turboprop engines?"

"This...how should I put it?" Igor Yaroslavsky thought for a while, and didn't make a fuss, but said bluntly to Zhang Qihang: "It is true that we have such a basic technology, but it is only With such a foundation, Mr. Zhang, if you are familiar with the development process of an aero engine, you should understand that the ignition of the core engine is only the first step in the long march, from the ignition of the core engine to the production of a mature and reliable engine that is sufficient for mass production. The engine still needs several years and a lot of capital and technology investment.

Even now that we have mature engine core machines and mature technical solutions, we want to produce TV3-VMA series turboshaft engines and TV3-117VMA-SB2/M turboshaft engines that are mature and reliable enough to meet the installation requirements in China. Propeller engine, without more than three years and a lot of investment is simply impossible. "

Is it really possible to produce TV3-VMA series turboshaft engines and TV3-117VMA-SB2/M turboprop engines in China?

The words of Sergei Izotov and Igor Yaroslavsky made Zhang Qihang's breathing heavy.

Because Zhang Qihang remembers very clearly that in 2003, the first flight time of the Wuzhi-10 prototype.

So the question is, why did the prototype fly for the first time in 2003, but it didn't start serving until 10 years later?
Almost all military fans can give the answer in unison: because of the engine!

That's right, it's because of the engine.

As a heavy-duty fighter, the Wu Z10 needs two turboshaft engines with a single power of at least 1500KW to meet the requirements of maneuverability and load, but it is a pity that if our country has always been in the "turbofan" If it is not possible to make up the turbojet", then we cannot even make up for it in the field of medium-sized transport helicopter engines.

In order to solve the "heart disease" problem of the Wu Z10, we had to import a civilian-grade PT6C-67B turboshaft engine from Pratt & Whitney Canada in the name of "civilian engine" to meet the power demand of the Wu Z10, but even so, Lao Mi, who realized that we were developing heavy-duty armed helicopters, immediately sanctioned us and prohibited Pratt & Whitney Canada from selling civilian-grade PT6C-67B turboshaft engines to us.

而现在，解决武Z10“心脏病”的机会摆在了自己的眼前：TV3-117VMA系列涡轮轴发动机的动力涵盖区间可是一直从1500KW一直涵盖到1700KW，完全能够满足武Z10对于动力的要求。

Taking a deep breath and trying to calm down his turbulent mood, Zhang Qihang nodded heavily: "I understand, I still have some understanding of the research and development of aero-engines, and I also know that from the successful ignition of the core engine to the production of mature products There is still a long way to go, now, please tell me, if Huateng Industrial Group guarantees investment, how long will it take to produce a prototype?"

Sergei Izotov and Igor Yaroslavsky exchanged glances quickly, then nodded together: "If it's just a prototype, two years is enough."

"Two years, right?" Zhang Qihang thought for a while and asked again: "Then from prototype to mass production?"

Sergey Izotov thought for a while: "If the whole process of flight test and certification goes well, it will take about two years."

Two years plus two years is four years.

Zhang Qihang didn't hesitate, he immediately slapped his thigh: "It's done!"

Isn't it just 4 years, even if you add 2 years in the middle, the total is 6 years, now it is 1997, counting from now, the mass production of engines will be realized by 2003, which is very good.

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

However, even though he had an idea in his heart, he didn't go home to see his daughter-in-law.

When he got home and saw his daughter-in-law, who was showing some signs of pregnancy, Zhang Qihang felt that his agitated heart soon calmed down, he took a deep breath, and said to Xia Muqing with red eyes: "Daughter-in-law, I'm sorry... ..."

Even though her husband has not been around for more than a month, Xia Muqing really misses her terribly, but she can make a phone call every few days to comfort her lovesickness. Knowing the situation of Zhang Qihang in Ukraine, Xia Muqing is not worried during her pregnancy. So anxious, seeing her husband standing in front of her now, the little unhappiness in Xia Muqing's heart disappeared long ago, and she said with a smile: "What's so sorry about this, we don't Do you call once in a few days... Hey, someone's eyes are red, are they about to cry?"

"..."

Looking at the smiling daughter-in-law in front of him, Zhang Qihang couldn't laugh or cry: You are still a master of destroying the atmosphere.
