Unparalleled True Technology

The vector engine is actually a jet engine, but the vector engine can provide propulsion in different directions through the steering of the jet port, so that the fighter can ensure that when the fighter is maneuvering at a low speed and at a high power angle, it can provide additional control. Control the maneuvering of the aircraft. The jet engine can only provide propulsion in one direction for the aircraft, either forward flight or reverse propulsion when landing.

After Wen Ming poured cold water on this group of guests, he naturally needed to give another sweet date, otherwise, this transaction would be just a technology sharing, and Wen Ming would not get more benefits.

Since the fourth-generation fighter jets, vector engines have been a must-have technology. In other words, fighter jets without vector engine technology are not fourth-generation fighter jets at all.

Wen Ming did not explain in detail why fighter jets need vector engines, because whether it is Howard or Lewis, they are more clear than Wen Ming about the power requirements that fighter jets need in the process of air combat.

But so far, the vector engine technology that can be maturely applied is only the binary vector engine technology on the F-22, and the steering of the jet port can only be used in the vertical direction of flight. That is to say, when the F-22 When flying in level flight, this force can only be used up and down, and when the F-22 is flying sideways, it can achieve side-to-side swinging flight.

So far, the multivariate vector engine has only theory, and there has never been a mature product that can be used for application.

The only countries in the world that have truly mastered vector engine technology are the United States and Russia, so Howard and Lewis are very clear about the advantages and disadvantages of vector engines. When Wen Ming suddenly mentioned the vector engine technology, they already had a premonition in their hearts, because their technicians had made a conjecture when analyzing the angel wing technology.

The Pentagon technician who asked the question before asked again emotionally: You mean, the energy engine can really solve the technical problem of multivariate vectors?

There is no need to say much about the difference between a binary vector and a multivariate vector, as long as you look at the name, you can roughly guess it.

For example, a binary vector is like a crab. Although it can walk in any direction, it can only walk sideways. But multivariate vectors are equivalent to human beings, they can walk however they want. For a fighter that needs agility extremely during air combat, this gap is absolutely huge.

Wen Ming laughed and said: It's not that the technical problems faced by multivariate vectors can be solved, but that the energy engine does not have such problems at all. The technical problem of the vector engine is that the thrust of the vector engine does not pass through the axis of the engine, and has a relatively large angle. This will add a bending moment to the engine. But for the energy engine, there is no problem of bending moment at all. Because the thrust of the energy engine is through the axis of the engine.

In addition, the vector engine has very high requirements on the material of the nozzle, because the gas ejected by the vector engine is hotter, stronger and higher than the gas ejected by the conventional jet engine. The multi-element vector engine technology is actually a rocket It has already been applied in the field, but the rocket only takes a few minutes, even if the nozzle has been destroyed by high temperature and pressure in a few minutes, it does not matter, but the fighter jet needs to be used for a long time.

Maybe the energy engine has not raised much requirements for the material at the nozzle, because the energy engine can form an energy layer inside the channel of the nozzle, and this energy layer can protect the material at the nozzle to a certain extent.

(ps: Please smile for the knowledgeable boss, don’t be serious.)

Hearing Wen Ming's explanation, the technicians at the Pentagon became even more excited, and they had the urge to snatch the display from Wen Ming's hands and study it. However, General Howard and Lewis were not very excited. Although this was an unexpected gain for them, it had little practical effect.

In modern warfare, what fighter jets really rely on is not air combat, but avionics systems.

Your radar didn't find me, I found you, even if one missile can't kill you, I can shoot another one.

The flexibility is high enough to avoid missiles, but it is not as good as fighter jets with more advanced avionics systems, which can attack you invisibly.

And the most important thing is that when the plane is flying at high speed, it is actually impossible to make big movements. No matter how flexible it is, what's the use if the pilot sitting in it can't stand it? Playing yourself to death also saved a lot of ammunition for the enemy.

It is not necessary to use the most advanced technology, but it must use the most mature and suitable one.

However, it is naturally beneficial to be able to improve to a certain extent. It doesn't seem to be very useful at the moment, but who can guarantee that it will not be useful in the future?

Just like when electricity was just invented, who could have imagined how many years later, electricity has become an indispensable energy in human life?

Wen Ming continued: Our current research on energy engines has set three directions.

The first is to reduce the power consumption demand of the energy engine, and at the same time increase the power of the energy engine as much as possible. The second is to study the combination of the energy engine and the laser weapon, based on the energy engine, to increase the power of the laser weapon as much as possible. Attack strength. The third is to strip out the energy layer research in the energy engine. If this research can be successful, then we will be able to realize the energy shield, a powerful defense method that can be applied in future wars.

Three research directions successfully attracted General Howard. However, Howard is also very clear in his heart that these three research directions are not easy.

Then, Mr. Wen Ming.

Howard asked, What I want to know is, what do you need? I don't think it's a question of research funding, right?

This question is very straightforward and normal. The U.S. military often cooperates with some defense contractors. They provide funds or some unique technologies, and then the defense contractors conduct in-depth research or applied research.

When the research has results, these results will also become the sole enjoyment of the US military. No matter which defense contractor it is, if it uses U.S. military resources in the process of researching a certain weapon, then they will never be able to sell the research results to other countries.

Wen Ming did not expect General Howard to be hooked so quickly. He has just become one of the defense contractors, but his position is not very stable, not only because he has not received a defense order from the US military so far, but also Because he did not have any substantive cooperation with the US military at all.

In the final analysis, this time's technology sharing was just a cooperation under pressure. After Wen Ming handed over the technical information to General Howard and his team, this time's cooperation came to an end.

Wen Ming introduced so many seemingly irrelevant materials before, but he wanted to reach a real cooperation with the US military. Only by obtaining financial support and technical support from the US military before starting research or during the research process can we ensure that we become a real US defense contractor.

It's certainly not money that we need.

Wen Ming smiled confidently, and said: What we need is the authorization to apply the binary vector engine technology. Of course, if we can get some mature vector engine technical materials, I think our research time will introduce a lot.

General Howard was stunned for a moment, and asked: Binary vector engine technology? Didn't you say that energy engine technology is more advanced than binary vector engine technology? Moreover, what you are researching is also energy engine technology, not vector engine technology.

The binary vector engine technology can be said to be unique to the US government, and even Russia's technology in this area is not as good as that of the US. It is precisely because of this prerequisite that the U.S. military and the U.S. government have imposed a technical blockade on binary vector engine technology. Not to mention exporting the technology to other countries, even in the U.S., not everyone is qualified to conduct research of.

Wen Ming smiled, and looked at the Pentagon technician who had been asking questions just now.

The technician helped Wenming explain: Although energy engine technology and vector engine technology are two technologies, strictly speaking, they have a lot in common.

ps: Sorry, I owe a chapter today and will make it up tomorrow. Another: The boss who knows the technical explanation can smile, if I really understand it, I won’t be a code farmer.
