Super military empire

"Even if we design a fighter plane that can withstand higher overloads, can our pilots withstand it?" Feng Lun's words are like a basin of cold water, extinguishing everyone's passion.

This is a fact that cannot be ignored.

The pilot cannot withstand too high an overload.

The so-called overload is gravitational acceleration. Under normal circumstances, a pilot who has been trained for a long time can withstand an overload of 10 g in a short period of time, but this is likely to cause physical damage. The United States, the Soviet Union and other countries, due to advanced technology, can not bear the overload. More than 9 g, in this process, that is, the pilot has to bear the pressure of 9 times his own weight at the same time.

The human eye has 3 seconds of oxygen reserve, and the brain has 10 to 12 seconds of oxygen reserve.When the overload limit of the human body is exceeded, the pilot will lose vision after 3 seconds, and the pilot will lose consciousness because of the excessive overload in 10-12 seconds.

At high overloads, the pilot bears several times his own weight, which causes the blood of the whole body to flow to the abdomen and the lower part of the legs due to gravity, which causes hypoxia in the heart and brain.

Although the J-10's maneuverability is good, it actually has many shortcomings in this regard. Most of the maneuvers, like all fighters in the world, are maintained at the level of 4~6g overload, according to the design standard of f16. , The overload reaches 6g for 45 seconds, and the 9g overload lasts for 15 seconds can be regarded as the first-class level among the three generations of fighters. In fact, the domestic J-10 cannot reach it.

Just like the American f-15, the 5g overload duration of the f15 reaches 100 seconds and repeatedly occurs; although its maximum available overload is 7.33g, the instantaneous flight overload frequently exceeds 9g in actual use.This is also the reason why fighter pilots are not allowed to make drastic and drastic maneuvers during the flight of the f-15 fighter, and many performances cannot be fully utilized.

J-10, 6g overload lasts for 38 seconds, 9g overload, only lasts ten seconds!

This is a shortcoming. Even if the 30° reclining seat of the fourth-generation American fighter f-22 is used, the pilot forms a posture where the back is reclining and the legs and feet are bent and raised. Even if the flight mask is used in the course of a large maneuver. Inject a large amount of high-concentration oxygen into the lungs of pilots, because compared with the United States, China's anti-overload research results have begun to transfer from the laboratory to the actual model development; in the anti-overload cockpit, new anti-g suit, compensatory vest, anti-load compression The backwardness of a series of technical measures, such as breathing and new anti-G actions, cannot allow the pilot to bear more overload!

Even if Liu Yijiu invested in these aspects from the beginning, there was no way.

Americans have been researching since the 1960s, although they do exist in China, their investment is very small.

The Ninth Institute has poured a lot of money into it, and it has not achieved much.

Feng Lun's current words are a profound domestic response to this defect.

"However, it is no longer the design of the previous aircraft itself that restricts the maneuverability of the fighter aircraft, but the maximum overload that the pilot can withstand and the duration of sustained high overload..." Liu Yijiu nodded and agreed with this view. However, this is not a reason to restrict our development of high-altitude and high-speed fighters! Even if our pilots cannot do it, we can develop drones without pilots!"

Liu Yijiu didn't want to waste too much time on this.

If you have any questions, you can come down to discuss it, but in this meeting, there is really no need to argue about this.

For the entire Ninth Institute, this project was originally a controversial project.

The same goes for the Air Force.

Liu Yijiu is persisting, so this project can only get continuous funding input these years.

Even Feng Lun, who is in charge of the research, objected. How could Liu Yijiu feel happy?

"Director Liu, since we talked about this project now, let's figure it out. I think everyone should have a lot of doubts about this project. What is the purpose? Although the Ninth Academy is self-financing, Project autonomy is also there." The representative of the after-installation headquarters quit at this time.

Even, he used words to block Liu Yijiu's intention to use them to raise funds by themselves and have project autonomy to prevaricate.

They did not say that they would cancel this project. The money was brought by Liu Yijiu, but it also belongs to the country, right?After spending so much money, let's not interfere, at least let us all figure it out, right?

"Yes, Director Liu, this project is indeed..." Zhu Houdao knows the source of the Double Triple Project best.

This is a targeted all-weather high-altitude and high-speed interceptor that was originally proposed in the 1960s to deal with the Soviet Tu-22m backfire bomber and the American b-1b supersonic bomber. The initial indicator was Double 26. From the 1960s At the beginning of the project, it went through several twists and turns. By the early 1980s, a large number of national projects were dismantled, and Liu Yijiu took over the entire team and basic research materials, and launched a double-three project with higher performance indicators.

High-altitude and high-speed, at that time, actually went through many arguments.

Liu Yijiu has always been forcibly suppressing opposition.Today, this kind of controversy has reappeared because of project funding issues, and even the project research team has lost confidence after so many years of setbacks.In addition, the world has not heard of any country that is studying this type of fighter. It is conceivable that the blow to researchers will be.

In this era, whether high-altitude and high-speed fighters are necessary is actually not too much debated, because everyone thinks it is unnecessary.

Even Liu Yijiu thought it was unnecessary. After all, the Tu-22m Backfire strategic bomber is known for its supersonic penetration capability. In the past, it penetrated the U.S. aircraft carrier fleet, so the military hoped to equip it more. Liu Yijiu was also prevented by the outdated design of this strategic bomber.

From the side, Liu Yijiu also thinks that the high speed is not very useful.

Now it supports the high-altitude high-speed fighter project, which is too contradictory compared to before.

Must let him give an explanation, right?

"I know that many people think this project is unnecessary. Because our current technology really cannot support the breakthrough of this project. Why do we need this project, I have said before, in the future, what we need is not only air supremacy, but Domination of the sky. Why did the Soviet Union build an orbital space station? Even exhausting national power? In the future, once we lose the dominance of the sky, we will be controlled by others everywhere, just as our navy cannot break through the third island chain that the United States has blocked. It’s not that easy to enter the universe... Now it seems that all of this feels a bit too early. At the beginning, our ancestors on the Diaoyu Islands did not send anyone to guard, but now the little devil is making trouble with us with this; The pond is obviously ours, and the surrounding small countries still compete with us...Space, if we don’t go up, future children and grandchildren will also encounter our current situation, maybe far away, maybe in the near future..." Liu Yi Nine is serious, even a little heavy.

This sentence is not his original.

But in the information he once saw, the chief engineer of Chang'e Engineering was facing a director of the Ministry of Finance and asked them what they spent countless manpower and material resources to do to the moon, and how much it would bring to the country if these funds were used to invest in local infrastructure. This is the answer when it is developing.

We will not go up to the moon now, and future generations will go up. Everywhere has been occupied by others.

Don't say that the universe belongs to all mankind. If you don't have the technical strength to plant the flag, it is all other people's.Just like the earth now, everyone knows that the earth is the home of the entire mankind and the wealth of all mankind. Why is there a division of low regions of the country?Why are there still developed and underdeveloped countries?

There are only so many resources. If you want to develop your own country and your own race, there will inevitably be disputes.

Liu Yijiu's words made everyone feel a little heavy.

Indeed it is.

Of course, some people think more about it, "Dr. Liu, what you said is the aerospace field. In this regard, the Ninth Academy and the aerospace industry are working hard. And we are talking about the high-altitude high-speed fighter project."

An elder at the aftermarket headquarters questioned Liu Yijiu.

Many people realized that Liu Yijiu was trying to change his concept.

"I don't think this project has anything to do with the future power of heaven." Liu Yijiu sighed. Not everyone is like him. He has hundreds of years of development experience to learn from.

No matter how wise people are, they may be confused.

"What we need is the means to enter suborbital space flexibly and quickly, and even the ability to conduct wars outside the suborbital space. It can be said that the Double Triple Project is just a basis. Only when the altitude of 30,000 meters and the speed of Mach 3 are solved, we It is possible to challenge to the altitude of 40,000 meters or even higher; challenge to the speed of Mach 4 or even Mach 6..." This is indeed a basic project, Liu Yijiu said before.

Feng Lun, who was in charge of this project, looked sad, "Materials, power systems, overall aerodynamic layout design, etc. are all difficult..."

It's not that he takes the ambition of others to destroy his own prestige.

It's the development of the project for so many years.

It is the overall technical level that restricts them from initiating adjustments to higher, faster, and farther levels.

"In terms of materials, we have a solution. As for the power system, we also have a solution. The two most difficult to solve are not the problem, the rest is the design." Liu Yijiu looked at Feng Lun, and it was originally here. I don't plan to say something, after all, there are too many people and it is easy to leak.

It's not that Liu Yijiu doesn't believe in the consciousness of the people here, but that sometimes they take into account some technologies and materials that are originally kept secret when designing, so that more people will know, and finally cause leaks.

"The material is solved? The power system is also solved?" Feng Lun clearly knew that the Ninth Institute has graphene, a material that is against the sky, and Liu Yijiu said that the solution must be the solution of industrial production.

He really didn't understand the power system solution, but they themselves were studying the related power system design.

"Yes, in terms of materials, you should be clear. As for the power system, we have made key breakthroughs in the design experiments of scramjet engines..." Liu Yijiu did not give too much explanation on this.

Scramjet, this is a world-wide super difficult technical project.

At the beginning, it was considered to be used in the aerospace field. After the rocket enters outer space, since there is no oxygen, it must carry oxygen inside. As a result, half of the rocket launch weight needs to be used to carry liquid oxygen or other Oxidizer to ensure combustion.The ramjet project does not need to carry an oxidizer. The aircraft engine absorbs oxygen during flight, which greatly reduces the weight of the spacecraft. It also means that the ramjet can generate data when the same amount of propellant is consumed. Times the thrust.

The Soviet Union and the United States have already begun research in the 1960s, and the Soviets even used this engine on their missiles.Sunburn, this kind of anti-ship missile that keeps Americans awake, has this kind of engine technology, which can produce faster than ordinary missiles.

"What is a scramjet?" Military personnel are very unfamiliar with this term.

Liu Yijiu asked Feng Lun to explain directly.

Feng Lun probably explained what a scramjet is, and then said with surprise, "If there is a breakthrough in technology in this area, our double-three project will no longer be difficult, and the only thing that needs to be considered is the design issue. After years of preparation, there have been alternatives."

Solving materials and power systems, even if the internal avionics system and other designs are a little bit close, the technical indicators formulated before can be completed.

Liu Yijiu said that this is the basis, and there is indeed nothing wrong with it.

Only by designing a double-three fighter can we consider designing a double-four or even higher performance high-altitude high-speed fighter.In order to obtain a longer range, it is necessary to make the body larger, and the higher the overload that the fighter needs to bear. This is a higher challenge to the design.

Now, Feng Lun has the confidence to complete this project.

"At present, we already have mature design drawings. We only need to produce full-scale samples for ground testing. This project is not far from being successful." Liu Yijiu did not explain much, and Feng Lun did not follow up. He raised the bar.

However, Feng Lun already knew that what Liu Yijiu wanted was definitely not just a double-three fighter.

It is only a fighter with double three indicators and does not need a scramjet at all. The only thing that puzzles Feng Lun is that it is not clear which project team is still conducting research in this area and has made a breakthrough silently.

Liu Yijiu took over the F-9 project with double 26 indicators, but now it has completely changed.This is no longer a high-altitude and high-speed defense interceptor, but an air-to-sky fighter!
