Great warships

Chapter 421 Spey is very important

Qin Tao is sincere.

After all, for him, a celebration dinner didn't cost much at all, but he hadn't been here much since he lured these old men over here. Since he came this time, of course he had to have a good drink with them.

The technicians here are also very hard. In the past few years, they have worked hard to sort out the manuscripts. In recent years, they have started to work on this prototype. Now it is finally successful. Of course, we have to celebrate.

When we arrived at the largest restaurant nearby, it was already past five o'clock, and all kinds of fine wine and delicacies were served non-stop.

"President Qin, I would like to toast you with a glass of wine." A man came up with a wine glass, and Qin Tao immediately raised his glass: "I salute you, without the help of your 430 factory, the turbine part of this gas turbine would not be so fast. Just produce it."

The person in front of him was the expert from Factory 430. At this moment, he had a smile on his face: "Mr. Qin, many domestic companies have cooperated with Mingzhou Group. Only we can do it indirectly through Institute 703." I have established a relationship with you, I don’t know if there is any project that can bring us!”

Qin Tao glanced at the other party: "You have many projects of your own. For example, the imitation of the Spey engine, you need to continue to work hard on research and development."

After the introduction of Spey, it was originally going to be handed over to Factory 410, but the largest and most advanced aero-engine factory in the country is working on turbofan six. In order to avoid the impact of Spey, it was transferred to Factory 430. .

Needless to say the story at that time, in a word, although the technology was bought back, it was eating ashes in the warehouse. Later, the Feibao had no engine, so it had to use the stock Spey, and even went to the British to buy a batch of second-hand. engine.

Now, since the other party mentioned it, Qin Tao naturally discussed it with them.

"Spey engine? Is that second-generation aircraft still useful? We originally planned to develop an aero-modified aircraft, but now it seems that there is no future."

The people in front of me were a little discouraged.

"Don't forget that the Navy is working on the Flying Leopard fighter-bomber. This type of aircraft needs two engines. In the future, we will need a large number of Spey engines."

"There is still a lot of stock in the warehouse, which is enough for a while."

"What about after that?"

Qin Tao looked at the person in front of him: "You can't say, let's talk about the future. We need more planes in the future. Should we let our flying leopards park in the factory building without engines?"

Qin Tao's volume increased slightly, so the people nearby heard it and looked over.

Wu Shengli walked over with a glass of wine: "What are you talking about? So devoted?"

"Leader Wu, Mr. Qin is talking about the Spey engine." The technician said: "This kind of engine used to be our key project, and it will also be related to the use of our flying leopard in the future. I don't know if the navy will purchase it. How many Flying Leopards?"

"Our country is poor. Even if we produce the Su-27 ourselves, the number will not be too many. Although the Flying Leopard does not look very advanced, but with its fuel-efficient engine, it can fly to the southern sea and come back. It is the type of aircraft that we are most lacking at present." Wu Shengli said: "I can't guarantee the specific number of aircraft, but we must be able to produce the engines of this type of aircraft, so that we will not be controlled by others!"

"With the development of aviation technology, the gap between aircraft bodies will become smaller and smaller." Qin Tao said from the side: "Our Flying Leopard fighter-bomber, even if it is a second-generation aircraft body, can continue to improve avionics. In order to achieve performance improvement, its cost is cheap, and there will be a large demand in the future, not only for the navy, but also for the air force in the future, not to mention more, there are still hundreds of them.”

Hundreds, then two hundred engines are needed!If the backup engine is included, the number required is even greater.

Of course, this is because Qin Tao said less. In fact, nearly three hundred JH-[-]s were equipped one after another. Of course, no one believes this statistic now.

"At the beginning, the country spent precious foreign exchange, so we can't let it go to waste. After you can achieve [-]% localization in the future, we can not only use this engine for our own use, but maybe even sell it."

"sell away?"

"Yes, there are still so many old aircraft in the world, many of which are using Spey engines. After the British closed the production line, those customers who want to replace the engine can only come to buy ours." Qin Tao said: "The total output of this kind of engine can be at least five hundred or more."

No need to do anything else, no need to occupy the bowl and look at the pot. For their 430 factory, let's talk about the localization of the Spey engine!
"This kind of backward engine needs more than [-] units?" The other party was surprised.

"That's right, if you don't believe me, we can sign an agreement, as long as you can complete [-]% localization, and if there is no place to buy it after production, you can sell it to our Mingzhou Group."

The other party shook his head: "Mr. Qin, we don't need to sign an agreement. We trust your judgment. After I go back, I will bring your words to the factory leaders. However, this imitation project has been stopped. If it starts again, it will take a lot of investment. funds."

Saying that everything else is secondary, money is the most important thing!

How to solve the money problem?

Qin Tao looked at Wu Shengli who came to join in the fun: "At present, the Flying Leopard fighter-bomber is still developed for the navy, so of course, the navy must invest in the engine for this fighter."

Wu Shengli's face changed instantly, you boy, I came to rescue you, but you came to my general instead?
Do you know how much it will cost to continue localization?At least a few hundred million!
Where do you get so much money?
If the navy has money, it might as well buy a batch of Su-30 as soon as possible.

"If our navy has no funds, there can be an alternative plan. For example, our Mingzhou Group will invest in subsequent research and development funds. However, in this case, when the 430 factory provides a large number of Spey engines to the army in the future , we also have to share part of the profits."

This is just what Qin Tao said. After all, the research and development of this kind of engine has been a national key project from the very beginning, and the country has invested a lot of money. It is inappropriate for Mingzhou Group to invest in it.Qin Tao's words can be beautiful enough, but Wu Shengli has no other choice.

"Let's find a way to report to the superior." Wu Shengli said: "The imitation of this engine must be carried out, and it must be improved to [-]% localized in the end."

"Yes, I will convey your instructions to the superiors."

The technician left, Wu Shengli looked at Qin Tao: "Are you running on us?"

"I don't mean that." Qin Tao shook his head: "In any case, Spey's localization must continue. Now our domestic engine research and development is in full swing. For their 430 factory, it is a good opportunity. , They can avoid a lot of detours, and our navy definitely needs Spey engines, so we have to tighten our belts and start this project.”

"What you said is simple. I really want to find an opportunity to bring you in and let you provide funds." After Wu Shengli said this, he remembered something: "You don't want to prevent them from obtaining gas turbine technology. Get them involved in the production of gas turbines?"

The QC280 of the later generations was produced by 430 Factory, so if they did it, they would definitely be able to achieve results, but Qin Tao is now against it.

"Yeah, they only need to produce the turbine part. If they get a full set of blueprints, they will definitely try to digest and assimilate them. This will waste time and energy. For them, they need to get Spey right first, otherwise the Flying Leopard will Without the engine, that's going to be a big problem."

Actually, there are more things that Qin Tao didn't say.

Gas turbines will not only be used on warships, but will also be used on the ground, becoming the power system of many equipment. It is good to argue among a hundred schools of thought, but with the current domestic foundation, it is not easy to gather all the forces to develop one, let alone use it. Talk about competition.

Qin Tao didn't want to cause internal friction in the competition, and he also believed that 703 would not let them down.

Wu Shengli nodded.

"Seeing our gas turbine ignite today, it finally solved a heart problem." Wu Shengli pulled back his thoughts: "Even if the speed is lower, we at least have advanced gas turbines."

"Yes, various subsystems are constantly developing. In a few years, after the completion of various supporting projects, our destroyer will be able to serve dumplings." Qin Tao is also very emotional.

After coming here, Qin Tao has been busy. After being busy for so long, he finally saw the harvest. The power problem of domestic warships has been solved, and he can build as many as he wants in the future.

"Thanks to you." Wu Shengli sighed.

The second-generation gas turbine purchased at the beginning solved the power problem of 115 and 116. Now the gas turbine is gradually mature, and there is no need to worry about future warships. All of this is the result of Qin Tao's promotion.

"Thank you very much. Please place more orders for our Mingzhou Group for warships."

"You boy, it's a good idea. The main destroyer of the navy must be determined through bidding. You Mingzhou Group can make preparations first and design these two different destroyers."

Qin Tao nodded: "We have been designing for a long time."

"You will face more powerful competitors." Wu Shengli said: "And, you should also know that you can't put all your eggs in one basket."

With so many shipyards in the country, Mingzhou Group can't build all the warships!Although Wu Shengli is upright and not afraid of the shadow slanting, there are still gossips behind his back.

Qin Tao smiled and said, "Those who are able will get more. If the navy doesn't place an order for us, then we will build warships for foreign trade, which are more advanced than those for domestic use. Let's see who we hit in the face."

"You are quite confident, boy." Wu Shengli also smiled: "Since we are in the Northeast, should we go and see the Su-27 production line?"

Qin Tao instinctively wants to shake his head. After all, the Su-27 production line has been producing fighter jets for the Air Force. It has not yet been used by the Navy. However, he has proposed the Su-30 project after all. Now that it is here, the past It's also a matter of taking a look. Besides, their Mingzhou Group is also providing titanium alloy components there, which can be regarded as a cooperative unit.

With this in mind, Qin Tao and Wu Shengli came to Institute 601 and Factory 112. However, after arriving, he understood Wu Shengli's purpose for coming here.

Wu Shengli didn't come to see those Su-27 fighter jets, but to see the modification of this fighter plane, that is, the imitation of the prototype of the carrier-based aircraft brought back by Qin Tao!

On the production line of Factory 112, many old men appeared. This scene is somewhat similar to decades ago. At that time, in order to help China develop the aviation industry, many old men also came here and worked together on the production line.

The same is true now, the big guys seem to have returned to the previous era of intimacy.

"At present, we mainly produce airframes, plus other parts imported from Lao Maozi." The retired Gu Lao heard that Qin Tao and the others were coming, so he came to receive them. At this time, Gu Lao was in good spirits.

"Among them, the raw materials of many titanium alloy parts of the airframe come from Mingzhou Group, which saves us a lot of procurement expenses." Gu Lao said as he walked: "In this way, the J-11 fighters produced by ourselves are more expensive than those directly produced." Imports save more than $1000 million."

Both Qin Tao and Wu Shengli frowned.

"Old Gu, we still need more than 3000 million yuan for our own production costs?" Wu Shengli asked.

"That's right, except for the airframe, which is produced by us, all other parts are imported from Lao Maozi, including the engine, telex system, weapon system, etc." Gu Lao said: "So, our current Saving more than $1000 million is already a very good figure.”

"Yes, this is only the first step after all." Qin Tao also said with emotion: "However, we must not be satisfied with assembly, we must constantly understand its technology during the assembly process, and continue to use our domestic Parts to replace it, and in the future, even if we don’t import Lao Maozi’s parts, we can produce this fighter by ourselves.”

Gu Lao nodded: "Yes, this is also our idea, but at present, there is still a long way to go for this goal."

It is easier said than done to replace imported parts with domestic parts.

When you replace, is it a complete imitation or an improvement?Among other things, Lao Maozi's electronic technology is backward. Even the electronic system used on the J-2 fighter jet in China is more advanced than that of the Su-27.

(This is not bragging. During a certain mission, when the Su-27 went up, the radar was jammed, and there was a snowflake, but the J-2 went up fine, and the radar could still find the target steadily.)
If it is a complete imitation, the performance is still backward. If you use your own improved product, will there be any problems in the replacement process?

For example, if the domestic radar is replaced, it will be much lighter than the original radar with the inverted card antenna. What about the lighter weight?Do you want a cement counterweight?

This is especially true in terms of engines. Although the domestic turbofan ten and the third uncle are similar in appearance and performance, it will take many years for the domestically produced engine to mature. Do you dare to replace it now?
"Currently, Lao Li is in charge of this project. Their task is to master the equipment technology of the Su-27 fighter jet and understand the principles of the Su-27. This is our next task. Only after a thorough understanding can we improve."

After the introduction of Su-27, there have been many project leaders. As for its first chief engineer, it is the famous Li Ming. In the 601 Institute, he is second only to Mr. Gu.

Sun Cong, who is now in his 30s, is only helping Li Ming.

"How's the progress of our navy's project?" After walking around the production line, Wu Shengli finally asked.

"Our research institute has specially organized a capable team to survey and map the imitation of the two T-10Ks. The person in charge, Luo Yang, is also a top student of our new third class." Gu Lao said, "I'll take you to have a look."

At the beginning, Qin Tao brought back two T-10K prototypes from the Nitka base, namely No. [-] and No. [-], as well as some landing gear and other accessories. For a long time, they were all eaten in the hangar of the Navy.

It wasn't until the introduction of the Su-27 production line that the two prototypes were dragged to the 601 Institute, and the experts here started the surveying and mapping imitation work.

For the navy, this is considered forward-looking. After all, seeing that the Varyag is approaching day by day, the carrier-based aircraft project must be launched in full swing. We cannot wait until the Varyag is refurbished. There is no shadow, we can only rely on helicopters to play the leading role.

However, since they have just mastered the production of the Su-27 airframe, it is quite difficult for the experts of the 601 Institute to imitate this carrier-based aircraft.

In an unremarkable small building in Room 601, Qin Tao once again saw the prototype machine he got back a few years ago.

One of them is still intact, and the other has been completely dismantled.

This is also the benefit of having two prototypes. What if there is only one prototype and it cannot be assembled after disassembly?
"Luo Gong, Luo Gong!" Elder Gu shouted to the busy people inside.

Luo Yang, born in 61, was born in 78, that is, the second year after the resumption of the college entrance examination. At the age of 17, Luo Yang was admitted to the aircraft design department of Capital Aviation University. Twice the age.

Among these people, Luo Yang was studying tirelessly, and even spent New Year's Eve in the study room.

Relying on this kind of energy, Luo Yang achieved excellent results. After graduation, he was absorbed into the 601 Institute, and just after entering, he joined the research and development team. The first task was just to develop the canopy, but he worked on it for months.

In the design office, Luo Yang continued to advance. When the Su-27 production line was introduced, he was originally busy with the Su-27 technology with Li Ming and Sun Cong. However, when he received a new appointment, he immediately Obeyed the decision and struggled on the prototype of the T-10K for more than a year.

In his 30s, he is in the golden age of a person, full of drive and energy. At this time, except for the bloodshot eyes, his whole body is still full of vitality.

"Gu Lao, what's the matter?" Luo Yang ran over and asked.

"Come on, let me introduce you to a few people." Gu Lao said, pointing to Wu Shengli at the side: "This is leader Wu, and he arranged your current project."

"Hello, Leader Wu." Luo Yang warmly shook hands with Wu Shengli.

"This is Mr. Qin from Mingzhou Group. He got the two T-10K prototypes."

President Qin of Mingzhou Group?
Luo Yang was a little surprised. When he saw Qin Tao just now, because he was too young, he just thought that Qin Tao was someone like Wu Shengli's secretary. Unexpectedly, he turned out to be the famous President Qin!
Qin Tao is younger than Luo Yang, but he has many deeds.When it comes to Mingzhou Group, everyone has to give a thumbs up in admiration. After all, the current Mingzhou Group is basically the leader of private enterprises.

For Luo Yang, the two prototypes are of course what he admires the most. Under the current circumstances, this project is kept secret, no one outside knows about it, and President Qin must have done more than one similar thing.

"Luo Gong, thank you for your hard work." Qin Tao stretched out his hand.

Only then did Luo Yang recover from his surprise, and took Qin Tao's hand.

"President Qin, you single-handedly promoted the development of the J-31A project. We all thought that you would fully support the project there. Unexpectedly, you still value this aircraft."

"The future of the Navy must be the J-31A." Qin Tao said very bluntly: "However, the research and development of that kind of aircraft is very difficult, and it will not be released in three to five years, and there will be no hope in ten or eight years. .For our navy, the most practical thing at present is the modification of the Su-27.”

Hearing what Qin Tao said, Luo Yang was both excited and embarrassed: "Mr. Qin, we have already disassembled one of the planes. After dismantling, we found that the technical difficulty of this plane is far higher than that of the Su-27." superior."

"Is it because it has an extra pair of duck wings?" Wu Shengli asked curiously.

From the appearance, the Su-33, which is the service model of the T-10K, has a pair of canards compared with the Su-27, but this is only superficial.

"Lao Maozi's aircraft carrier uses a ski jump to take off, so in order to increase the take-off performance, they specially added a pair of canard wings, but its changes are definitely more than that." Luo Yang said: "It can be said that its technology is more advanced than that. The Su-27 has increased by half a generation."

Different canards have different functions.

This can be seen on the canards of several famous aircraft in the world.

For example, the Rafale fighter jets, the French have completely ruined the delta wing aircraft. In the Mirage 2000-5, they added a fixed duck wing to the front of the delta wing. Its function is to provide vortex.

Vortex is the product of the development of aerodynamics, which can greatly improve the lift of the aircraft.

Let’s look at the Typhoon developed by the four European countries. The distance between the canard and the main wing of this fighter is too far, and basically there will be no eddy current effect. This canard is mainly used to control the aircraft, which is equivalent to an additional aerodynamic control surface.

These two types are called short-distance coupling and long-distance coupling respectively, while the domestic J-[-] combines these advantages and disadvantages, and the distance is neither far nor close, which belongs to the original medium-distance coupling.

The Su-27 does not have canards. This kind of fighter with large side strips and body fusion is already very beautiful, but on the Su-33, canards appeared, and then transitioned to the Su-35 and Su-37 . (There are two kinds of Su-35 in history. The ones we purchased are already in the later stage, without canards, but on the Su-90, the experimental prototype of the 35s, there are canards.)
