624 conference rooms.

"On behalf of all the employees of Institute 624, I welcome Mr. Qin and his group to inspect." Old Jiang said with a smile: "Everyone applauds and welcomes you!"

Without Qin Tao, there would be no such project as theirs. But after the project was negotiated, Qin Tao never came again. Even if they wanted to express their gratitude, they would not have a chance. Now, Qin Tao finally came, and they were very happy.

During the negotiations, Mr. Jiang was the main representative. After returning, Mr. Jiang was appointed as the chief designer of WS-15. Although he was already covered in white hair, he was full of energy.

"Old Jiang, I just brought a group of people to inspect our J-31 A project, and then come and take a look. By the way, I have brought you a new force. Let me introduce this Ms. Vanessa, from Atlas, Rainbow Country."

Qin Tao did not bring in more than a dozen guests from the Rainbow Country. Vanessa was brought over by Qin Tao as their representative. At this time, when she heard Qin Tao's introduction, she smiled on her face: "I am very happy to be here to work, and we will work hard in the future."

Qin Tao was a little surprised: "Vanessa, can you speak our Chinese?"

"Since I have decided to come here to work, of course I have to learn the language here so that it is convenient for communication." Vanessa's tone was a bit strange, but she could express her meaning clearly, which made Qin Tao feel extremely moved.

Is this too amazing?

It took less than a month since I came into contact with them. During this period, the other party was able to communicate in oral language!

"Ms. Vanessa, what exactly did you do in the past?" Mr. Jiang asked Vanessa.

"The part I am responsible for is the single-crystal turbine blades. Although we only have the Ata 9k50 engine in China, we still want to improve it and make its performance more advanced. Our single-crystal turbine blade technology has been developed and mature."

Mr. Jiang was not calm in an instant.

For aircraft engines, turbine blades that can withstand high temperatures are also an important technology. Single-crystal turbine blades are an advanced technology proposed in the late 1970s.

As the name suggests, it is a cast blade with only one grain. It eliminates the lateral grain boundary that is sensitive to cavity and cracks, and makes all grain boundaries parallel to the stress axis direction, thereby improving the use performance of the alloy, improving the high temperature strength of the alloy, and further improving the comprehensive performance of the alloy.

Although everyone knows that when manufacturing, the magnetic field generated by super electromagnets is used to gradually form single crystals with a uniform atomic arrangement during condensation, the specific operation is still under test.

And the person in front of you already has strong abilities in this regard!

"Ms. Vanessa, are you willing to join our single crystal turbine blade research and development team?" asked Mr. Liu, his words trembled a little because of excitement.

This is not just for the improvement of the turbofan-15a. Once developed and mature, it can be used on various aircraft engines!

Compared with the material composition, technology is also very important. In this regard, China has suffered a great loss.

The SBE engine, which was introduced at the beginning, obtained all the material and technical information, but there was no technology, so it has not been 100% domestically produced so far.

In contrast, the technology introduction of r-79 has been much smoother. With Qin Tao's insistence, they brought back the complete set of design drawings and technical materials, material composition lists and process steps, and even some production equipment.

Therefore, they can complete the imitation of the engine in such a short time.

However, the prototype r-79 engine is still too backward, and imitation is only the first step. The next improvements and improvements are the most important. Using advanced technology to increase the engine's power and reduce the engine's weight is their focus in the future.

All kinds of advanced technologies need breakthroughs, and General Qin brought them a group of talents!

"Of course I'm very honored to be able to participate in this key model."

Now she already knows that the turbofan-15 developed here is to provide supporting facilities for the famous J-31a, and the technical difficulty is far greater than that of the Rainbow Country's engine. She is very excited and very excited.

There is nothing wrong with the choice to come here!

For people like her, salary and other things are even in a secondary position. She just wants to make what she learns work.

"Old Liu, I heard that our project is progressing very smoothly." Qin Tao said: "The prototype has been built."

"Yes, our initial work was still very smooth. Now we can draw a lot of tricks. However, if we continue to improve, we still face great challenges. Although this engine is powerful now, the thrust-to-weight ratio is very low. If compared, it is not even as good as the third-generation engine, which is similar to Spbe."

The thrust of the r-79 engine is 152 kN, but its weight is as high as 2.5 tons. Calculated, the thrust-weight ratio is about 6, the thrust-weight ratio of the third-generation engine is about 8, and the thrust-weight ratio of the fourth-generation engine is 10.

The way to increase the thrust-weight ratio is to increase the thrust and reduce the weight on the other hand.

"So, are we planning to improve on the existing engine now?"

Mr. Jiang nodded.

"Sorry, I think I originally wanted to take a shortcut to do this. In the end, I might even go far away, get up early and get to the evening party."

Qin Tao's words made Mr. Jiang stunned: "Mr. Qin, what do you have any opinions?"

"I don't know much about aircraft engines, but I heard that this kind of thing is a whole body, so I wonder if we should first develop the core engine, after a lot of experiments, thoroughly understand the technology, and then add the external duct to make a brand new turbofan-15a."

The right way to develop a military engine is to first study the core engine, understand the parameters of the core engine thoroughly, and then assemble the engine. Only in this way can we be at ease.

We want to do this too, but this is too much money!" said Mr. Jiang: "We have invested 200 million to complete the production of the prototype. I am afraid that this modification will not be able to be made by 2 billion."

Positive research and development is definitely good, but it is too expensive!

"The money that should be spent must be spent, not to mention 2 billion, even if it is 4 billion, it must be studied. The funds required by the project will be solved by the superiors. If it cannot be solved, it will be obtained from our J-31A project."

J-31a is an international cooperation project and has raised hundreds of millions of dollars in funds. Qin Tao is full of confidence in this project. As the project continues to develop, someone will definitely join in.

It is also necessary to take out some of the money to support the Turbofan-15. After all, this engine should not only be used on the J-31A, but also on the J-20. It will support the future sky of the motherland.

Mr. Jiang sighed.

"It's all circulated in our system. Follow Mr. Qin to have meat. Now, we have realized it. Mr. Qin, if our upgraded engine is mature, you will be the biggest contributor!"

Qin Tao accepted Mr. Jiang's praise.

"I started this project with one hand, so how could I watch it give up halfway? However, I didn't invest much money in this project. The main reason is that our project has been recognized by countries around the world, so there will be a steady stream of customers to invest in us. The most successful thing about our project is market-oriented operation!"

If it were to rely on state investment, this project would never have gone to this day. Look at how much money the J-10 has invested. It was originally intended to be a naval carrier-based aircraft project, and it would be impossible for the J-31A to obtain too much money. The Navy can only support the J-17.

However, J-31 a has come to this day and the prospects are very good. What do they rely on?

It is market-oriented operation!

Mr. Qin's creativity completely saved the project and also promoted the progress of the domestic aviation industry. Everyone was very moved by this.

"Yes, Mr. Qin, your market-oriented operation is unique in the world. In this regard, you have made great contributions to our aviation industry!"

Just as Qin Tao took a break from his busy schedule and inspected the aviation industry, a group of people were still arguing across the ocean.

Facing China's J-31A fighter jet, the Americans felt insulted, so they decided to speed up their research and development, so the first coordination meeting on joint attack aircraft began.

The person who presided over the meeting was William Perry, who was known as the military killer.

After taking office, William Perry reviewed existing fighter development projects, and not long after, the Navy's A/F-X project and the Air Force's MRF project were cancelled.

These projects eventually merge into jast projects (joints)

technology, jointly developed a joint fighter of multiple services.

"The Cold War era has long passed. For us, we should not use their own fighter jets as in the past. When McNamara was in office, we used F-4 fighter jets, a single model and a universal multi-service service. In the future, we should also do this."

The Air Force generals present couldn't help but complain, do you think we are willing to use it? In the era of F-4 fighter jets, we have lived in the shadow of the navy for a long time!

However, they did not argue. After all, the Air Force's F-22 is developing, and they already have at least a high-end fighter. As for what to do with low-end aircraft, they don't care, but the Navy should be anxious.

"So, I decided to merge our Calf project with the Astovl project into Jast. It ended up being a huge project!"

What? Everyone was surprised.

"Mr. William, it's impossible to do this. Think of our F-111 plan, which ended up being an engineering sandbox." Marine officers complained.

Especially the last one is the vertical take-off and landing fighter project needed by the Marine Corps. Should this project be merged into it?

"I've heard such a saying." William Perry ignored the complaints of the Marine Corps. He continued: "If fighters continue to develop towards the trend of becoming more advanced and more expensive, the United States will have only one aircraft in the future. The Air Force will use it in the morning, the Navy in the afternoon, and the Army in the evening. The Marine Corps can only be used on February 29 of the leap year. Therefore, the goal of our current plans is to be able to be sagged, multi-purpose, and low-priced. In this way, everyone can have aircraft!"

"Now, it's not the time to complain. If you want to complain, then complain about the collapse of the Red Empire!" William Perry continued: "Now, we need to listen to the design plan of the bidding team, and Boeing will come first!"

In fact, news of the merger of these projects has long been spreading, and among various companies, Boeing is the most prepared.

"This is our design drawing." Boeing technicians opened the slide.

When the design of the plane appeared on the screen, everyone laughed.

"This big mouth reminds me of toads!"

"Yes, that big mouth is just for funny!"

Faced with these doubts, Boeing's people were unmoved and continued to introduce: "This design was developed from our AVX-70 project. It uses a single-chuck-type air intake and a mid-engine lift nozzle..."

"Next, Lockheed's project!"

Daniel walked up and opened his slideshow. Sure enough, the ridicule came as scheduled.

"You Lockheed company is too shameless. How can you plagiarize China's projects!"

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! "Yes, we would rather have a toad mouth than a plane like a Chinese fighter plane! When our planes go into the sky, what will others see our plane?"

Different paths are the same! After repeated calculations and designs, Lockheed's designers found that the appearance of China's projects is the most suitable.

So, they brought this project, and as they imagined, countless people despise them.

At this moment, listening to these sarcasms, Daniel felt extremely frustrated. How could this be their project that plagiarized the Chinese? This project was originally created by them! But now when they said it, no one believed it. Although they had checked it themselves, no one found that anyone had leaked the secret.

Their project has also been developed for a long time.

At first, they planned to use the configuration on the astovl project: the canard wing design was paired with the trapezoidal main wing, but later gave up.

Because canards are not popular in the United States, including the widely circulated saying: the best position of canards is on other people's fighters. The radar reflection area brought by canards is plaguing, and the resistance to crossing the sound barrier is higher than that of the general configuration. Therefore, they made modifications, first canceling the canards and becoming fighters close to the delta wing design, and then adding a horizontal tail to return to the traditional design.

Although the final design is similar to the f-22, it actually went through some twists and turns.

Now? It is directly called plagiarism! In the United States, where the most technologically powerful, plagiarism is to be ridiculed.
