The most lacking thing in the fighter of the East is the engine, after all, this thing is the laurel of industry, few countries can develop it, even if it is the French, the technical reserves in this area are not enough, the M53 used on the Mirage 2000 is a single rotor, and the M88 used on the Rafale is still a product of surveying and mapping imitation F404, and the East is even worse, over the years, it has been engaged in turbojet, where is the technical reserve of turbofan engines.

"Yes, it uses Spey, after all, although it starts with J, in fact, it is a double-shot strong six." Of course, Lu Lao will not tell the matter that he has just obtained the third aunt, and this needs to be kept secret for the time being.

"Yes, this aircraft is a follow-up product of the Qiang-5, and the variable sweep wing is just right for low-altitude and high-speed penetration and ground bombing." Qin Feng also followed on the side and said, "By the way, Lu Lao, how is the development of the telex operation?" ”

"It's almost developed, after all, this is our strong point." Lu Lao nodded: "When the single shot was strong six, we had already come up with digital telex, and later in order to support the J-11, we even engaged in advanced three-axis and four-redundant digital telex, especially with our Loongson No. 1 processor, the data processing ability is very strong, but it is ......"

The Yankees present were stunned.

Three-axis four-redundant digital telex? The technology of the Orientals is already so advanced?

The Tomcat fighter was an anti-heaven existence in that era, it had a digital flight control computer for the first time, codenamed DFCS, and many people began to boast that it represented the highest level of the third-generation fighter of the United States, saying that the F-15 was still mechanically stabilized, and the F-16 was still an analog computer in the early days, etc.

In fact, the Tomcat fighter's digital flight control computer is only used to control the variable sweep wing.

In the process of flying, according to their own needs, the variable sweep wing is adjusted to the appropriate angle, and the Yankees feel that this is unscientific, so they have engaged in a large number of sensors, enter the special flight control computer, and adjust the sweep angle of the aircraft according to the flight status, which is completely automatic.

This digital flight control is used to adjust the variable sweep wing, nothing else, all kinds of rudder surfaces are still carried out by mechanical stabilization, even if it is to the F-14D, Grumman has not come up with a full set of digital flight control, even the F-16, the Block40 type using a digital computer, was only put into service in 88, which is just a single-engine medium fighter.

Although the Super Tomcat has undergone a number of upgrades, the flight control still uses the original technology, and in the East, it has already played three-axis four-redundancy digital telex on the J-11!

"Are you engaged in three-axis four-redundancy digital telex?" Hades was shocked again.

"Yes, as a strong attack aircraft, you need to fly near the target at an ultra-low altitude, and then drop bombs, if the target is in a mountainous area, the risk of flying at ultra-low altitude is very high, we need advanced digital fly-by-wire operation to ensure flight safety, and it can also be automatically pulled up when needed, so that the pilot can't react." Lu Lao introduced.

"So, what were you just hesitating about?"

"It's just that when we were developing this aircraft, we simply enlarged the strong six into a double engine, and many of the shape parameters did not blow enough wind tunnels, so the flight control law was not familiar with it, and there were many difficulties in writing the flight control of this aircraft."

The Americans looked at each other a few times, and Brian nodded solemnly.

"Rest assured, we have a lot of research experience with the aerodynamic layout of the variable sweep wing, and we are willing to help if you need it."

What do you say about double hair strong six, isn't it our tomcat, the aerodynamic shape of this tomcat is our first creation, of course we have a perfect flight control law, we can help!

"But, we don't have any money, if we ask you to help, we will definitely have to pay a lot of money, forget it, let's do it ourselves!"

Brian frowned.

Hades thought for a moment: "Well, it's the same as the project just mentioned, we don't need money, but you need to show us the results that have been developed at this stage, so that we can easily improve for you." ”

"That's not good, we have spent more than ten years of hard work in order to develop the digital flight control of the variable sweep wing, and it is easy to have phased results, how can it be shown to you, forget it, forget it."

Originally, the Yankees were a little reluctant, but when they saw Lu Lao waving his hand, they suddenly reacted: they are asking for benefits from the Orientals, and the Orientals are not stupid, of course they don't give it!

Tomcat fighters also need digital flight control, but Grumman did not invest in this research, because it costs a lot of money, their improvement projects, mainly on avionics and engines, now, while the Oriental has built a digital flight control platform, they only need to use their own mastery of flight control law on it, that is, to engage in software, this only needs to arrange a few engineers, and after the development, they can transplant the relevant technology to their own Tomcat fighters, It is equivalent to spending only half or even less of the R&D expenditure to solve this problem.

Moreover, this digital fly-by-wire flight control is not only used in existing aircraft, and when the stealth aircraft is built, it also needs digital flight control, not to mention anything else, just the vertical tail that is tilted outward, and the control is different from the original vertical tail, only digital fly-by-wire can control it!

They couldn't ask for it.

However, the Orientals do not want to!

What to do?

"Mr. Lu, you should know that if you want to make the fighter more flexible, you need to relax the static stability." Brian spoke, "You have almost zero experience in this area, and you need our help. ”

"Okay." Lu Lao nodded: "However, the improvement work has to be carried out here, and we will never fly our own plane to you, and when the time comes, there is a chance that it will become the second model of peace." ”

Those present were a little embarrassed.

"It's okay to modify here, but we need to copy the flight control program after the work is over." Brian said.

"Okay, but this flight controller is our J-11, whether it can adapt to your tomcat I don't know yet, if something goes wrong and falls the plane, don't blame us."

"Of course not."

"Then we will pull this project up, and we have to invest a huge amount of money to build an iron bird test bench, alas, I don't know if it can be approved."

"What, you don't even have an Iron Bird test bench?" The Yankees felt deceived, didn't they just say that they had been doing it for more than ten years? What have you done in the past ten years? Don't even have an iron bird platform?

Before the aircraft goes to the sky, it needs to be supported on the ground first, check the situation of each rudder surface, even if it is the hydraulic era, it has to be done again, and when it comes to the fly-by-wire flight control period, it is necessary to repeatedly test on the iron bird platform, and the J-10 is because the experiment on the iron bird platform is the richest, so in the process of test flight, there has not been a mistake.

Lu Lao and they are also studying digital fly-by-wire flight control, but after all, they are halfway home, not original, and it is difficult to get up with digital fly-by-wire flight control, and now with the help of American experts, the development progress will be faster.

Or the same idea as before, let the Yankees make a cameo as a consultant, or the free kind!

Of course, the Yankees may not really help, and may even dig holes, but as long as they come here to work, they can still give themselves a lot of inspiration and help.

As for waiting until the end of the work, the Yankees want to take the technology away? Then it depends on the specific situation at that time, these studies are all here on our side, and if the Yankees want to take away the information, they have to look at our faces, we laugh on the surface haha, behind the scenes......

"There was one before, and then it was demolished." Lu Lao said: "Because for a while, we felt that the hydraulic operation was enough, but now, we plan to start the plan again, this time the iron bird platform has to be coordinated, not only the current J 11, but also the transformation of the stealth model in the future, and the iron bird platform is also needed." ”

Yankees rest assured, Tomcat's flight control is good to say, the key is the stealth flight controller, and after the computer calculates the most suitable shape, you have to blow the wind tunnel, according to the shape to write the flight control, these all need to spend money, do it here in the East, they only need to pay some engineers' salaries and travel allowances, experimental equipment and the like are provided by the Easterners, they can save a lot of money!

That's right, they came here to save money, after all, the natf plan didn't count them, they couldn't ask Congress for money, they could only save money through the Orientals, and when the time came, they could directly bring the finished product back and get recognition directly!

The big guy ate and chatted at the same time, and the meal was very harmonious, not like there was a suspicion at all.

When they had finished eating, they went to see the wooden prototype again.

"The shape of this plane was really designed by you?" The Yankees still don't believe it.

"That's for sure, our appearance is currently the first of its kind, can we still imitate other people's?"

The Oriental tone is very proud, and when it comes to facelifting, we are serious!

Think about the fact that the YF-22 and YF-23 have not yet been declassified, and it is impossible for the Orientals to get these technologies, so it is really possible that they developed them.

"Of course, only the appearance is not enough, if the aircraft wants to better obtain the stealth effect, it also needs a special stealth coating, we ......" Lu Lao said here, and stopped in time: "Don't look at the fact that we only have wooden prototypes here, in fact, our various research and development projects are steadily unfolding......

Could it be that the Orientals also developed a stealth coating?

The visitors of Grumman Company looked at each other a few times and made up their minds that they must send more people to stay here to help, and maybe they will be able to get in touch with more secrets of the Orientals!

Here they imitate their tomcats, and they, in turn, take some technology from here, and that's right!

The Yankees inspected for a whole day, and the next day, a cooperation agreement was formally signed, and then more than a dozen engineers, including Stephen, were left, and more than 20 engineers were promised to be transferred from the United States to help develop it.

With their help, even if it is digging a pit, it will leave a lot of valuable research and development experience, Lu Lao is very satisfied, but Lu Lao is also worried about some things.

After sending the Americans on the plane, Lu Lao and Qin Feng walked back, taking advantage of the fact that there was no one else around, Lu Lao asked.

"Mr. Qin, when the research and development is completed and they want to take away the technology, what should we do?" In the past few days, when we have been deliberating, this final operation is missing.

"Then you don't need to say, pull the gate!" Qin Feng said: "The computer that is running at high speed, suddenly pulls the gate, there will be an error, especially our main storage device, that is, the hard disk, the head is suspended on the high-speed rotating hard disk, and suddenly the power is cut off and falls, and the head will completely scrap the hard disk, and we can't help it, although it is a double backup, but the hard disk is damaged at the same time." ”

Lu Lao instantly understood, this method is good!

Of course, they will keep a backup in advance, but to the Americans, it is already broken, and they have to start all over again! Then, we ran out of money and didn't do it!

Only Qin Feng can come up with this kind of operation.

"During this time, there were additional guards in the factory, and these American engineers lived in guest houses outside, and they were delivered by car every day, so that they could not come into contact with other secrets. Or set aside a special quarantine area for them to use for research. ”

"Well, Mr. Qin, we'll arrange this."

"Mr. Lu, Mr. Qin, someone is visiting!"

This guest is the same as a marquee, one group left, another group came, Qin Feng only planned to come here to have a look, but he didn't expect to have been here for ten days and half a month! Now, who else is visiting?

"Who?"

"The slaughter of Factory 132."

When Song Lao of the 611 Institute was still selling noodles at the entrance of the research institute in order to subsidize R&D funds, the 132 factory made a special profit by exporting the Jianqi Factory, which is a huge contrast because the 132 factory has a technical bull: Tu Lao.

Tu Lao was born in 1927, graduated from the Department of Aviation of Modu Jiaotong University in 1951, and was assigned to the Hafei factory after graduation, and in a few years, he became the section chief of the design department of the aircraft factory, in 1956, the first aircraft design office of Shenfei was established, and then evolved into the Northern Institute, code 601, Tu Lao was transferred that year as the leader of the fuselage group.

Lu Lao, Song Lao, and Tu Lao, who were all the backbone of the Northern Institute, were the backbone of the Northern Institute back then.

Later, in order to prevent a possible war in the north, a large number of factories moved south, Chengdu set up a 132 factory, Tu Lao was transferred, in the 132 factory to improve the J-7, when the country opened, Tu Lao was responsible for leading the team to negotiate with the Marconi company, the introduction of Western electronic equipment to improve the J-7, Tu Lao was already the chief engineer of the 132 factory, and concurrently served as the chief engineer of the J-7M aircraft.

In order to facilitate external contact, the 132 factory was renamed Chengdu Aircraft Company, referred to as Chengfei, which is not the same thing as the famous Cheng Luoma.

The most potential project of Jian-7 is the Super 7 project, which was originally proposed by Lao Ba, and the 132 factory cooperated with Grumman, and the project is progressing smoothly, but now it is ......

In the reception room of Factory 320, Tu Lao walked back and forth, and when he heard footsteps from behind, he hurriedly walked to the door.

"Lao Lu, you are really, Grumman Company sent someone to you to discuss cooperation, why didn't you notify me!" Tu Lao's face was complaining, and then he looked at the young man beside Lu Lao: "Mr. Qin, it's a pleasure to meet you, I'm Tu * Da, just call me Lao Tu." ”

Tu Lao is now in his sixties and has long reached the age of retirement, but he is still struggling on the front line, running back and forth for the Super Seven project he has in mind.

The project was proposed by Lao Ba, but Lao Ba did not believe in the technology of the 132 factory, so he found Grumman and wanted Grumman to be the general contractor, so that the position of the 132 factory was embarrassing.

When Grumman announced the termination of the cooperation, Lao Ba also notified Factory 132 and officially gave up the Sabre 2 project, but Tu Lao did not plan to give up!

Tu Lao is not low, but his body is very thin, and the hair on his head has long since fallen out.

"Elder Tu, it's a pleasure to see you, you're here for the Super Seven Project, right?"

"yes, this project has progressed to the point, it would be a shame if it was thrown away!" Tu Lao's eyes were full of expectation: "Mr. Qin, I heard that under your mediation, the Peace Model Project has got a good ending, can you help us promote the Super Seven Project?" ”

Tu Lao came here for this, because it is located in Sichuan Province, it is inconvenient to communicate with the outside world, Tu Lao news is closed, and he does not know that the peace model project has been successfully solved under the promotion of Qin Feng, until yesterday, I heard that the people of Grumman Company came to the 320 factory, and only after inquiring did they know what happened, and they decided to come to the 320 factory that night, but the traffic is inconvenient in this era, and the toss has only arrived now.

Wait for him to come, the Grumman people have just left!

Now, even if he wants to ask Mr. Qin to help mediate, there is no one from Grumman Company present, Tu Lao is a little disappointed, but he is still full of expectations, hoping that Mr. Qin can help him.

"Of course, Elder Tu, what do you think?"

Hearing Qin Feng's words, Tu Lao was overjoyed.

In the eyes of the outside world, Tu Lao is an all-rounder, understands technology, and knows how to communicate with foreigners, the original negotiation with the Marconi company, it was Tu Lao who took the lead, and the super seven project was also Tu Lao and foreigners to negotiate little by little, in fact, Tu Lao has no choice, can only carry it, he is still a technology, trade, and negotiation with foreigners, there is no way.

Now, Mr. Qin can share the contact with foreigners for him, which is naturally the best.

"Mr. Qin, if we can continue to cooperate with Grumman......

Before Tu Lao's words were finished, Qin Feng shook his head: "No, cooperation with the Americans is no longer possible." ”

The honeymoon period is over, there is no going back, in a few years, the Red Empire will collapse, and the relationship between the two sides will be even more difficult to say, good horses do not eat back grass, since the other party took the initiative to refuse, then how can we continue to catch up with the Americans?
