"Do you know, how much does it cost to do that? It's painful for us to build a third-generation fighter in China, so you have to be ambitious!" Zheng Yucheng was amused by Xie Kai.

Stealth fighters, on the basis of the current domestic basis, cannot be carried out at all.

Zheng Yucheng doesn't know what technology is needed for stealth fighters, but he knows that across one or two generations, it is all a trench.

Otherwise, the level of domestic equipment will lag so far behind the gap in the world?

"Xie Kai, our domestic foundation, you know. Wang Guilin also smiled bitterly, "Let's not talk about how much money is needed, it's just that we don't know what the technical indicators of that fighter are." Domestic estimates do not understand people either. ”

Xie Kai's ideas have always been wild, and it is very difficult to engage in cross-generation fighter research under domestic conditions.

"Others don't understand, don't I understand?" Xie Kai shrugged, about stealth fighters, he knows even more than ordinary fighters, for pre-research, put forward various technical indicators, it is not a problem at all. "For a long time upfront, it doesn't even cost much. After all, now we are not engaged in a formal project, but a pre-research ......."

The domestic electronic system is not good, and the computer industry is not Xie Kai who got a chip, which is also painful, and as for the pneumatic layout of the stealth design, it is even more painful.

How could Xie Kai not understand?

Start to show up stealth fighters early, so as not to let the F-22 of the US imperialism seek defeat alone, let alone let their stealth bombers laugh proudly.

There are still many countries in the world that have the ability to develop the third-generation fighter project.

When it comes to stealth fighters, even the traditional European industrial powers Britain, Germany and France are powerless, and the old Maozi after the collapse of the Soviet Union has spent an T-50 for I don't know how long it has not been in service, and it is even more so that the third brother's family is about to be empty.

Only China has two stealth fighters, J-20 and J-31, at the same time, although the J-31 is a garbage thing.

Stealth bomber, in addition to the US imperialist B-2, F-117A later because of poor performance, China's H-20 can compete with it, Lao Maozi's stealth bomber did not even see a shadow, can only pull out the Tu-160 White Swan, which has not been used for a long time, to walk around the world.

The domestic technology research and development capacity is not as good as imagined, nor is it as bad as imagined, as long as you give time, you can get it out.

The project was established more than ten years in advance, even if it took a few more years, it would be possible to get a stealth fighter earlier, right?

Xie Kai's idea is very simple.

"Pre-research?" Zheng Yucheng frowned and asked Xie Kai, "Can the things you come up with be so simple?"

It's not that they don't know the problem of pre-research.

Since the founding of the People's Republic of China, domestic scientific research has gradually formed a system, which is different from foreign scientific research in that it is not developed and equipped.

The scientific research ideas of the generation of production equipment, the generation of trial production, and the generation of pre-research have been put forward after the reform and opening up.

In particular, the development of rockets and missiles, which are the most capable aerospace systems in China.

"Yes, it's pre-research, even if you want to set up a project, you have to wait until various technical indicators come out to measure our domestic production capacity and industrial base, isn't it?" Xie Kai said.

If it were possible, he would like to start building stealth fighters now.

If you do get it, maybe you can export it to the Soviet Union before the collapse of the Soviet Union.

However, one can only think about it.

The engine is not good, not to mention the vector engine needed by the stealth fighter, I don't even know how to start in China, and even the ordinary turbofan engine has not been done.

The avionics system is not good, the fire control radar is not good, and even the design of the aerodynamic layout requires the work in this area without the slightest experience......

"Do you know what their next-generation fighter looks like?" Wang Guilin couldn't directly refute Xie Kai, for fear that Xie Kai would pick on him.

"Of course, I know that the next generation of fighters, air superiority fighters have obviously been eliminated, ultra-high speed, ultra-high-altitude flight fighters have proved to be not in line with the mainstream development at present; can break through the following points, I summarize the abbreviation of 4S, that is, Stealth (stealth), SupeoniCruise (supersonic cruise capability), SuperManeuverability (super maneuverability), SuperiorAvionisforBattleAarenessandEffetiveness (super information advantage) 。 Of course, there may be other aspects, but I don't think of it at the moment, anyway, I just have some ideas......"

Xie Kaitian shamelessly said that he summed it up by himself.

It's not that he doesn't want to say that it has been summarized abroad, but at present, only the US imperialists are studying this thing, and all the data is highly confidential, and even the Soviet Union has not received any news.

"Tell me about it. Zheng Yucheng and the others frowned, Xie Kai dragged English, which was a bit of a headache, but Qi Zhiyuan was interested.

"First of all, let's talk about invisibility. This is not that the fighter is really invisible, but that the reflection cross section of the radar is as small as possible. Not only did the aerodynamic layout and shape design make the plane reflection area as small as possible, but also the stealth coating that could absorb the detected radio waves emitted by the radar, and the weapon had to be built into the fighter's interior, not mounted under the wing or belly of the fighter...... Even the tail engine needs to be treated with infrared radiation simplification......"

For stealth fighters, the radar reflection cross-section is extremely small.

This can only be achieved by a variety of means, not only in the design of the aerodynamic layout, but also in the built-in magazine, the engine in the tail, etc.

There's just so much involved.

What a non-professional person like Xie Kai can know, that is, what can be known on the Internet.

Theoretically, there is nothing wrong with any of these claims.

"Supersonic cruise capability, you don't need to explain too much about this thing, right?"

"You don't have to say much about that. "Everyone else understands.

The J-9 fighter project, which was dismounted before the Super 7 Project, not only requires supersonic cruise, but also requires higher performance.

Xie Kai wasn't prepared to waste his time on this.

This not only needs to consider the shape and aerodynamic layout design of the fighter, but also has requirements for the entire power system, which puts forward strict requirements for the power system like the super-maneuverable ability.

"As for super-maneuverability, it's about a good aerodynamic layout and a better engine. Xie Kai was hesitant to say something about vector engines.

The new generation of stealth fighters must use vector engines to provide greater maneuverability.

There is a hard requirement for the super-maneuverability of the fourth-generation fighter, that is, to have the ability to maneuver over stall, that is, the ability to maneuver at a high angle of attack.

The vector engine can ensure that the additional maneuvering torque provided by the thrust vector is used to control the aircraft maneuver when the aircraft is flying at low speed and large angle of attack and the rudder surface is almost failing.

Before Xie Kai could finish speaking, he was interrupted by Wang Guilin, "We don't even have the most basic turbofan engine, and you don't know the problem of heart disease in the domestic aviation industry." If there were engines, even the J-9 wouldn't have to be dismounted......"

"Yes, Xiao Xie, this problem is indeed very serious. You don't want Rongcheng Engine Factory to develop new engines for this project, do you?" Qi Zhiyuan also asked Xie Kai with a frown.

The R&D investment in aero engines is too large.

And we don't know when we will get the results.

Any engine, especially the engine with higher performance requirements, once it is started to be developed, without the financial support of the state, will have a serious impact on the capital chain of the entire base.

None of the aviation projects involved in the 404 now have engines, and if the Super Seven is not imported from the Soviet Union, it will also face the problem of no engine.

For the Super Seven project, Xie Kai purchased 200 engines at a time.

"Sooner or later, we'll have to make up for it. Xie Kai said faintly.

Regardless of the engine problem, everyone can continue to communicate happily.

Who doesn't know that the Chinese aviation industry has a heart disease problem?

Or, in the entire Chinese industrial system, engine technology is lacking. On the one hand, there is an international blockade of China, and on the other hand, China's foundation is too poor.

When the People's Republic of China was founded, there were few things that China could manufacture.

Later, with the assistance of the Soviet Union, the industrial base was established......

"But if you start this project, we need a supporting engine project, whether it is the engine of Yunten, or the engine of the current Super Seven Project, it is not a little money and can be completed in a short time. It is not possible for us to start three engine projects at the same time. Wang Guilin's expression was serious, "The base's finances simply cannot support the funds for more advanced engine research. ”

It's not that the base management committee doesn't want to, but it doesn't dare to think about it.

Everyone knows about engine R&D investment, as well as the basic situation in China.

Even if a full set of production technology has been introduced, until now, more than ten years have not completed the localization of bass engines.

"Didn't you say it, it's just a pre-research?" Xie Kai didn't say anything about the vector engine.

He knew that as soon as he said that he needed such an engine, which he had not even heard of in the country, the whole project would be resisted.

Engine problems, can only wait.

Either wait for the collapse of the Soviet Union to be introduced from Lao Maozi, or wait for the domestic engine technology level to improve.

Stealth fighters are only at the drawing design stage, and they cannot be made in a short period of time when there is no foundation in the country.

Take it one step at a time, you can't wait until you have an engine and then start working on stealth fighters, right?

"Don't interrupt, let him finish. Zheng Yucheng, who had never spoken, asked Xie Kai to continue to introduce.

He was already interested in the kind of fighter that Xie Kai was talking about.

"Super information advantage. This is the core thing, whether it is stealth or super maneuverability, it is relatively easy to solve. This fighter was originally designed with the development of future equipment in mind, just like the upgrade performance reserved for our 359 tank, the data processing power is more demanding, and it can even be said to be a mobile supercomputer......"

Under such requirements, radar, infrared, data link, electronic warfare system, and warning system will be integrated into a complete battlefield perception system.

Whether it is for electronic technology or information processing technology, the requirements are very high.

Even the third-generation fighters in China have not yet been solved, and the avionics system and radar system do not even have the most basic ones that can be looked down, and then ask for new ones, which is more difficult and more challenging.

Xie Kai didn't even dare to tell everything he knew.

Once you say it, you will be resisted because it is too difficult, or you don't even see any hope of success, and the indicators are too high.

Almost all of the large number of weapons projects that were launched in China in the 80s have one thing in common: the performance indicators are too high, the funds needed are too large, and the foundation is too weak......

"Such a project, even the pre-research work, is very difficult. After Xie Kai finished speaking, everyone in the management committee was silent for a while, and after a long time, Zheng Yucheng spoke.

Xie Kai nodded, "That's true." After all, there is no reference to this, the United States has already started such a project research in the seventies, and the Soviet Union seems to have it. ”

The F-117A is about to show its face on the battlefield.

"It has nothing to do with us what other people are working on. The base's family background is not solid enough to withstand too much tossing. Wang Guilin was not happy.

Zheng Yucheng likes to do big projects, and Xie Kai's heart is bigger than Zheng Yucheng.

"It's not right now. The reason why Factory 132 and 611 do not oppose it is that they think that people are on our side and it is more beneficial to them. Xie Kai pulled the topic back.

Seeing that the time was not early, Zheng Yucheng asked Lu Yang to go to the cafeteria to bring food to the office for a few people, and they continued to discuss.

"I think Comrade Xie Kai's proposal is very good. At present, there are few projects involved in the base, which are completely their own, which is equivalent to a position to supply funds, which is very unfavorable for future development. Zheng Yucheng supported Xie Kai's proposal.

Base 404, so far, does not have too many core technical research teams.

Whatever project is carried out, it is all in cooperation with others, technology research and development, are all responsible for the cooperation team, once there is a problem, in the end 404 has nothing.

"The base can work on other projects, and even recruit the Yunshi design team back. Wang Guilin naturally disagreed.

Xie Kai's purpose is not only to want someone, but to introduce so much, obviously he wants to do such a project himself.

Bai Yanjun had been listening sullenly, and he wanted to ask when the base would insert a foot in the naval equipment project, obviously, it was not appropriate now.

"Why don't you wait until the Super Seven Project is over, and then think about anything else?" Qi Zhiyuan asked. "In the early stage, according to Xiao Xie's proposal, a group of core backbones can be obtained from the 132 factory and the 611 institute, and even other domestic aircraft design and research institutes, to do preliminary preparations. ”

The old guy's words are completely not to offend anyone on either side.

Naturally, it won't cost much to engage in preliminary preparations, which also satisfies Xie Kai's intentions, and at the same time, Wang Guilin no longer objects.

"That's no problem, that's just what I'm suggesting anyway. Xie Kai knows that if you want to directly launch the project, it is impossible at all, "The future development of the base itself is based on research and development, this is a problem we have discussed before, isn't it? ”

"Perhaps, you can ask the Air Force what they think, and maybe you can get some funding......

"It's for the military's funding!" Xie Kai's answer made everyone stunned.
