Chapter 720 For the Zhi-20 Project

Of course, Boguslayev would not unconditionally trust the Europeans. They had been deceived more than once. This time, it was very likely that the Europeans were here to sow discord between them and the East. However, it would be a pity to ask them to give up, so they just need a good way.

 Now, Mr. Qin has given this good idea!

As for whether the Europeans will find out in the future, let’s put this aside for now. At least we can’t offend the Orientals now. Otherwise, if the project is terminated, will they still have the nerve to come back to the Orientals?

 They can distinguish interests. If the Europeans are deceived and fall for it, that would be called stupidity.

Qin Tao is also very satisfied that the other party can make such a choice. This shows that Ermao has not been fooled by Europe. They still know who their real friends are. If this project can continue, it will do more good than harm to the country.

  Various domestic projects based on D-227 can continue to be pre-researched.

“Mr. Qin, after the D-227 engine project is officially put into production, have you ever thought about continuing to cooperate with us in other engine fields?” Boguslaev said: “For example, helicopter engines?”

 The domestic aviation engine industry is still relatively weak. In addition to the large engines used for transport aircraft, the engines used by helicopters are also backward.

 At present, China can only produce Z-9 engines. Even some parts of Z-8 engines have to be imported. Until now, Z-8 has not achieved 100% localization.

Motor Sich Company manufactures engines, and their production line also has helicopter engines. The most famous one is the D-136 engine. The output power of this engine is 8,500 kilowatts, making it the most powerful turboshaft engine in the world. You can know by comparison: The largest CH-53 Super Stallion helicopter in the United States uses the latest GE38 engine, with a power of only 5,600 kilowatts. Therefore, three units must be installed to be enough, and the maximum take-off weight is only 38 tons. , and what about Lao Maozi’s Mi-26? The maximum take-off weight reaches 56 tons!

However, there are not many applications for heavy-duty helicopters. Therefore, the Mi-26 helicopter was never produced after the collapse of the Red Empire. Motor Sich Company only refurbished this engine. Motor Sich Company has There are no orders for new D-136 engines.

 Now, they can’t wait to sell all these to the East. The market in the East is huge! As long as it is produced in the East, it will be used in the East.

"For us, what we need most is an engine with a maximum output of about 1,600 kilowatts." Qin Tao said: "If this kind of engine can be successfully developed, the market will be absolutely vast. According to my estimation, our domestic orders can exceed a thousand. Not to mention export models.”

Boguslaev originally planned to sell the D-136 engine to the East. The technology of this engine is ready and can be output from the production line at any time. However, the use of this level of turboshaft engine is too narrow, such as heavy helicopters. The purchase cost is high and the scope of use is narrow, so the quantity is not high.

The engine of this level mentioned by Qin Tao is of great use. This kind of engine can be said to be the role of snake oil. Because it is the most suitable engine choice for ten-ton helicopters!

Let’s take the United States as an example. The American Apache and Black Hawk are the most common and widely used helicopters. The former is an armed helicopter and the latter is a general-purpose helicopter. They both use the 1,450-kilowatt T-700GE- 701 engine. So far, only the Black Hawk helicopters imported from the East in the 1980s can go to the plateau because of their powerful engines.

Lao Maozi’s engine is similar. The TV3-117 engine used by their ten-ton Mi-28 is also of this level, with a power of 1454 kilowatts. At the same time, the TV3-117 is also the engine of the Mi-171 and Ka-52 helicopters.

 There needs to be a similar engine in China!

"Mr. Qin, can the power of the turboshaft engine you are talking about be reduced? The TV3-117 engine we produce has a power of less than 1,500 kilowatts, which is still far behind your requirements." Boguslaye Husband said.

Speaking of turboshaft engines, Boguslaev always thinks of the D-136 engine first. In fact, they also have the TV3-117 engine on their production line!

This engine is a turboshaft engine developed by the Klimov Engine Design Bureau on the basis of the TV2-117A engine. It was developed in the 1970s and was later put into mass production at the Zaporizhia Aviation Engine Manufacturing Plant.

 That’s right, it’s the Motorsich Company led by Boguslaev now! In the era of the Red Empire, Lao Maozi really had no selfish motives. He produced various products according to what was suitable, regardless of which republic he belonged to.

After the collapse of the Red Empire, the demand for this engine has also been greatly reduced. In recent years, only maintenance work has been left. Anyway, the Klimov Design Bureau was originally located in Damao, so Damao can completely put this into production in its own country. An engine, just like the AI-222.

 Now, since Qin Tao said he wanted a turboshaft engine, he could certainly bring an engine of this level to Dongfang, but the power would not meet Mr. Qin’s requirements!

“The engines you are currently producing are still at the level of the 1970s.” Qin Tao said: “This engine is already outdated. My friend, I have just said that we must successfully develop this engine.”

 Develop?

Boguslaev understood: "Qin, are you saying that we need to develop a new engine?"

"Yes, it is a new research and development. You will provide some technical personnel, and we will provide some technical personnel to form a joint R&D organization. Our turboshaft engine has a normal output power of 1,600 kilowatts, and the maximum power is It needs to reach 2,000 kilowatts, and you know why."

Ten-ton helicopters use two engines. Under normal circumstances, a single output of a certain power is enough. However, if one of them fails, the other one must output emergency power, even if the engine is turned off. Even if it is burned out, it must provide higher power as much as possible to meet the needs of single-engine flight.

 Hence, turboshaft engines must possess such explosive capabilities.

Since the other party has this idea, Qin Tao has to follow his own goals. Armed helicopters are only equipped by the army, so he doesn't care. However, the navy, air force, and even the army all need ten-ton general-purpose helicopters. This is called The Z-20 project has already begun to be developed. In the Navy, this ten-ton general-purpose helicopter will serve as the main carrier-based helicopter in the future.

 What the country still lacks is an engine. Now that we have this opportunity, we must work on this project.

The power of TV3-117 engine is actually barely enough, but its technology is too backward!

After the Mi-171 is available in China, people will involuntarily compare it with the Black Hawk. This comparison will reveal how backward the Mi-171 is: looking at the fuses alone, there are a huge number of fuses on the Mi-171. If one of them burns out, Just look for it one by one, but the Black Hawk only has one fuse, and the fuse was even removed when it was remodeled! (This joke comes from the Internet, I don’t know whether it is true or not)

 The engines developed in the 1970s are definitely lagging behind now, in the late 1990s, with insufficient power and a poor power-to-weight ratio.

Jet engines have a thrust-to-weight ratio, which is the ratio of thrust to weight. The greater the ratio, the greater the thrust at the same weight, which means the engine is more advanced. Second-generation engines are around 5, and third-generation engines are between 7 and 8. Around 10 for the fourth generation engine.

Turboshaft engines use shaft power to measure power output, so there is a power-to-weight ratio, which is the ratio of the output power to its own weight. Take Lao Maozi's TV3-117 as an example, the power-to-weight ratio is around 5. However, the power-to-weight ratio of domestically advanced turboshaft 10 has reached 7.

“In addition to power, we also have weight requirements. Its weight is about two hundred kilograms, and it cannot exceed too much.”

“Qin, this request you made is too difficult!” Boguslaev immediately shook his head.

Their TV3-117 engine weighs more than 300 kilograms. Now, Qin Tao has reduced the weight to more than 200 kilograms, and the output power has increased by one to two hundred kilowatts. How is this possible?

"Only with this requirement can the power-to-weight ratio exceed 7." Qin Tao said: "Modern advanced turboshaft engines must meet this indicator. What we want to develop is an aviation turboshaft engine with the world's advanced level. Of course , given our industrial base, the fuel consumption rate can be relaxed a little."

The fuel consumption of the TV3-117VM turboshaft engine is 0.319 kg/kWh. The fuel consumption rate of the later domestically produced turboshaft 10 is 0.28 kg/kWh. The data is already good, but if it is compared with the data of France’s latest Aneto 1K In comparison, it is much worse. The other's is 0.228 kg/kWh. In other words, the other's is more fuel-efficient and can fly farther with the same fuel tank capacity.

 Domestic engines have always had the problem of high fuel consumption. This cannot be solved overnight. There are trade-offs among various functions. The problem of power and power-to-weight ratio is solved first, and the fuel consumption is left to be discussed later.

"Fuel consumption can be relaxed to 0.28 kg/kWh, but as for the engine control system, we must not continue to use the old engine control system. We need a new bilingual full-power digital control system." Qin Tao continued to make requests, thinking In order for the engine to have more advanced performance, of course the control system must be improved so that it can be more perfectly integrated with the flight control.

The dual-redundant full-authority digital control system, referred to as FADEC, can fine-tune a series of parameters such as the engine's throttle, speed, stator blade inclination angle, etc. through various sensors, fuel metering components, and compressor control components to achieve complete control. of digitization.

These requirements put forward by Qin Tao made Boguslayev very helpless: "Mr. Qin, what you proposed are all the latest turboshaft engine technologies. I'm afraid we don't have this capability!"

 Lao Maozi can't do anything else but archeology. They simply cannot get involved in these brand-new technologies.

"We have it." Qin Tao said: "You have the foundation and we have advanced technology, so we cooperate in research and development." Qin Tao said: "Over the years, we have developed many advanced materials and processes, such as the overall engine Blisks, such as ceramic matrix composites, single crystal turbine blades, etc. By applying these technologies, we can greatly improve the performance of the engine. In this way, with our joint efforts, we can complete the development of this new turboshaft engine. Although it is difficult, it is within the acceptable range for us.”

Originally, Qin Tao said joint research and development, but Boguslayev didn’t take it seriously. Now he finally understands that joint research and development is really necessary!

 Motor Siqi Company has mass production capabilities and they have rich experience. What Qin Tao needs is their experience. Coupled with Dongfang's breakthroughs in advanced technology over the years, the two parties jointly developed and solved the problem of helicopter engines!

As long as there is no problem with the engine, the Z-20 will be born!

Nowadays, the navy's ships have to worry about the hangar at the back when designing them. The domestic Z-9 is too small and the imported Ka-27 is too tall. You have to plan it during the design to determine what helicopter to carry. After the -20 is successfully developed, there is no need to worry about this. Just design it according to the hangar of the Z-20. This is the most suitable carrier-based helicopter for the navy.

  Not only can it serve the navy, but the air force and army aviation are also in need, especially on plateaus. Such professional plateau helicopters are needed. With abundant power, they can fly stably on plateaus.

Unconsciously, Mingzhou Group has been involved in more and more aviation projects. However, these projects are still related to naval equipment. As a group that manufactures warships, of course, it must also consider the needs of carrier-based aircraft.

 Qin Tao is looking forward to it.

"Okay, Mr. Qin, we will carefully consider these requests you have made. I hope we can jointly develop the world's most advanced helicopter engine." Boguslaev said. He is also full of expectations. After all, the market for medium-sized utility helicopters is indeed huge.

This joint research and development cannot be a matter of saying a word. There is still a lot of work to be done in the follow-up, a lot of negotiations to be carried out, and various benefits can only be distributed before it can be carried out, but Qin Tao can afford to wait.

This matter has come to an end, Qin Tao took Zhao Ling and left the Friendship Hotel.

“Ermao’s choice should be the best for us,” Zhao Ling said. “The Europeans have overestimated their own weight if they want to disrupt our project.”

"Yes, if the Red Empire had just collapsed and the Europeans did this, Ermao would definitely put his hot face on his cold ass. However, after so many years, the Europeans have not given them anything except deceiving them. The good thing is, of course they won’t completely trust the Europeans,” Qin Tao said.

I always cry wolf, but no one believes it. I still remember how the Europeans tricked me into dismantling the nuclear-powered aircraft carrier. At this time, if they directly placed the order and paid the down payment, maybe Bogusla Yev can make up his mind to sell to European engines even if he breaks the contract with Dongfang. However, it is just a bidding, and we don’t know whether it will succeed or not. Of course, we cannot bet all our money on the Europeans.

“Next, let’s take a look at the domestic automobile industry, see which automobile factory is about to go bankrupt, and buy back their production qualification certificates.” Qin Tao said.

Electric cars are an emerging industry. Whoever enters the industry first will be the boss. The profits of this thing are not low. After all, cars are going to enter thousands of households. There are also policy supports. Qin Tao must promote it. Ma Ming is a go-getter. Technically, it's not very suitable to engage in this kind of business.

However, I am also engaged in technology, but now I have almost completely become a businessman.

At this moment, Xu Zhengyang answered the phone and reported to Qin Tao: "Mr. Qin, someone from the Antonov Design Bureau is here and wants to talk to you."

 Antonov Design Bureau?

Qin Tao helplessly put his hand on his forehead. He, a shipbuilder, is really about to become an airplane builder!

When the other party comes, it must be for the An-70 transport aircraft. After all, the D-227 engine will be produced here, and the Antonov Design Bureau will definitely look forward to selling the An-70 transport aircraft.

 Does the East need this kind of aircraft?

Now Dongfang is short of large transport aircraft, so that the Air Police-2000 modified with an IL-76 body cannot be modified without limit, and can only use a few. However, since Dongfang already has plans to independently develop large transport aircraft, It is definitely not possible to purchase transport aircraft from the Antonov Design Bureau.

 In fact, in the late 1990s and early new millennium, many people issued such an initiative: they hoped that Dongfang could introduce the An-70 transport aircraft and quickly change the current situation of the lack of large transport aircraft in the country.

However, there is a big gap between ideal and reality. This kind of transport aircraft will eventually have no chance with the East. No matter how advanced its technology is, there will always be many problems that cannot be solved. For example, if you always buy and buy, you will not have yourself. R&D strength, what will happen next? After all, it’s good if Lao Maozi can survive for ten or twenty years by relying on archeology, but what about the future? In the future, we will still have to do independent research and development. It is better to have independent research and development capabilities now. This step must be taken out.

Qin Tao has never been optimistic about the idea of ​​buying an aircraft production line from Lao Maozi, but now that the Antonov Design Bureau is here, of course he has to greet them warmly.

The meeting took place at the Air Force compound. Mr. Lin, who had retired at home, couldn't wait to relax, and he got to know the other party, so he was the one to receive him. While receiving the meeting, he was waiting for the arrival of Qin Tao and others.

“Mr. Qin, it’s a pleasure to meet you. I am Victor, and this is Jinchenko. We are both designers of the An-70 transport aircraft.” Victor first extended his hand.

Victor? Qin Tao's mind inexplicably thought of the old man with a bruised nose and swollen face.

In 2019, the 81-year-old Victor is still working at the Antonov Design Bureau, receiving a meager salary to spend his old age. Who would have thought that on the way home, three people suddenly ran out Man, surround him, punch and kick him.

The police arrived late and immediately classified it as a fight. The three men who beat Victor were let go. Instead, Victor was taken to the police station. After some investigation, they found out that Victor was the victim and the three men were the attackers. There is no grievance or grudge, the other party just recognized the wrong person.

 Old experts like Victor are definitely national treasures, but in Ermao's place, no one would care about them, and the police did not bring justice to Victor, but just let him go.

Just from such an incident, you can know how little attention Ermao has paid to these experts in the country. It’s a shame that Ermao can develop.

Now, looking at this sixty-year-old man who was working hard for the An-70 project, Qin Tao suddenly felt a surge of sympathy in his heart.

It's too pitiful. I'd better keep them all. Here in the East, old experts are still more valued.

“Mr. Qin, Mr. Qin?”

Mr. Lin became curious. What happened to Qin Tao? Why did he suddenly stare at Victor? This is very rude!

"Well, I'm sorry, I think you look like an old friend of mine from Damao." Qin Tao shook hands with the other person, and then looked at the second person.

Kinchenko is actually more famous than Viktor. He is a senior expert at the Antonov Design Bureau and has rich practical experience. From the initial An-26 to the final super giant An-225, Kinchenko was involved. He He is an expert in aerodynamic layout and wind tunnel experiments. Moreover, he has also served as an academician of the Academy of Information Sciences and lectures at various universities. He has more than 30 years of teaching experience and is famous all over the world. His subordinates have produced many professional theories and Technical talent.

 However, it was precisely because he mainly turned to teaching in the later period that Jinchenko was not particularly involved in the development of the An-70 transport aircraft. He was not the chief designer and had to be Victor's deputy.

"Mr. Qin, I heard that your Mingzhou Group purchased the An-225 transport aircraft. How is it operating now?" Jinqinke asked.

The relationship between Mingzhou Group and Antonov Design Bureau is still good. The world's number one transport aircraft is owned by Mingzhou Group. The other party said that this relationship is of course paving the way for the subsequent negotiations.

“Well, in our words, it means that if it is not open for half a year, it will be open for half a year.” Qin Tao said.

An-225 consumes too much fuel and has high requirements for airports. Therefore, there are too few employers who can afford to hire their aircraft. However, as long as they hire, it is necessary.

For example, some very large special parts that cannot be transported by sea due to timeliness requirements can only be transported through it. The last time they accepted a commercial transportation task was six months ago, but the freight was also quite high.

"Yes, this kind of transport aircraft is too big, and the materials that need to be transported by it are too few. However, our An-70 transport aircraft is different. It is an all-rounder in the air." Jinchenko said: "I hope that you will Interested in this kind of transport aircraft."

“Do you regard me as a customer or a partner?” Qin Tao asked.

“All of them.” Jinchenko was indeed very experienced in society and introduced him quickly, while Victor, who was engaged in technology, became the audience.

"You are currently cooperating with Motor Sich Company to produce D-227 engines at Tianjiao Aviation. This engine is also the engine for our An-70 transport aircraft, so you are a partner. However, our transport aircraft is very excellent, so You will definitely purchase a batch, this is a customer again, Mr. Qin, what do you think?"
