"The vector engine is actually a jet engine, but the vector engine can provide propulsion in different directions through the steering of the jet, so that the fighter can ensure that when the fighter is flying at low speed and large power angle, it can provide additional maneuvering force to control the aircraft's maneuvering. Jet engines, on the other hand, are only capable of providing propulsion in one direction, either to fly forward or to provide reverse propulsion when landing. ”

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

"Since the beginning of the fourth generation of fighters, vector engines have been a necessary technology, or rather, a fighter without vector engine technology is not a fourth-generation fighter at all."

Wen Ming did not go into 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 fighters need in the process of air combat.

"So far, the vector engine technology that can really be applied maturely 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. In other words, when the F-22 flies horizontally, this force can only be used up and down, and when the F-22 flies sideways, it can achieve side-to-side swing flight. ”

"So far, the multi-vector engine is only theoretical, and there has never been a mature product that can be used."

The only countries in the world that have really 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 they heard Wen Ming suddenly mention vector engine technology, they already had a premonition in their hearts, because their technicians had put forward a conjecture when they were analyzing Angel Wings technology before.

The Pentagon technician who asked the question earlier asked again with some emotion: "You mean, the energy engine can really solve the technical problems of multivariate vectors?" ”

The difference between binary vectors and multivariate vectors doesn't need to be said, just look at the name to be able to guess roughly.

For example, a binary vector is like a crab that can walk in either direction, but it can only walk sideways. But multivariate vectors are equivalent to human beings, and they can go whatever they want. For a fighter who is extremely agile in the course of air combat, this gap is absolutely enormous.

Wen Ming laughed and said, "It's not that the technical problems faced by multi-vector can be solved, but that the energy engine doesn't have such a problem at all. The technical difficulty of the vector engine is that the thrust of the vector engine does not pass through the axis of the engine, and there is a large angle of deviation, so that a bending moment is attached to the engine. But for energy engines, there is no question of bending moments 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 for the material of the nozzle, because the gas emitted by the vector engine is hotter, stronger and higher than that of a conventional jet engine. In fact, the multi-vector engine technology has been applied to rockets for a long time, but the rocket only takes a few minutes, even if the nozzle has been destroyed by high temperature and high pressure in a few minutes, it does not matter, and the fighter needs to be used for a long time. ”

"It is possible that the energy engine does not have much higher material requirements at the vent, because the energy engine can form an energy layer inside the channel of the vent, and this energy layer can protect the material at the vent to a certain extent."

(ps: Knowledgeable boss, please smile, don't take it seriously.) ）

Hearing Wen Ming's explanation, the Pentagon technicians became even more excited, and they had the urge to snatch the display in Wen Ming's hand and study it. General Howard and Lewis, however, were less excited, and while it was a windfall for them, it didn't really work.

In modern warfare, fighters really rely not on air combat, but on avionics.

Your radar didn't detect me, I found you, and even if one missile can't solve you, I can have another one.

It's flexible enough to dodge missiles, but it's not as good as a fighter with a more advanced avionics system, which can stealthily hit you.

And the most important thing is that when the plane is flying at high speed, it is actually impossible to make big moves, and even if the flexibility is high, what is the use of the pilot sitting in it who can't stand it? Playing yourself to death also saved a lot of ammunition for the enemy.

The technology does not necessarily have to use the most advanced, but it must use the most mature and most suitable.

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

Just like when electricity was first invented, who could have imagined how many years later, electricity would 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 requirements 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 energy engine and laser weapon, based on energy engine, to increase the attack strength of laser weapon as much as possible. The third is to strip out the energy layer in the energy engine, and if this research can be successful, then we will be able to realize the energy shield, a powerful means of defense that can be applied in future wars. ”

Three research directions successfully attracted General Howard. However, Howard also knows very well that these three research directions are very difficult.

"Then, Mr. Wen Ming."

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

It's a very straightforward and normal question, and the U.S. military often works with defense contractors who provide funding or some unique technology, and then the defense contractor conducts in-depth research, or applied research.

When the results of the research are available, they will also be the sole benefit of the U.S. military. Any defense contractor that uses U.S. military resources in the research of a weapon will never be able to sell the results to another country.

Wen Ming didn't expect General Howard to take the bait so quickly, he had just become one of the defense contractors, but his position was not very stable, not only because he had not received a defense order from the US military so far, but also because he had not had any substantive cooperation with the US military at all.

This time the technology sharing, in the final analysis, is only a cooperation under pressure, and after Wen Ming handed over the technical information to General Howard and his party, this cooperation ended here.

And Wen Ming introduced so many seemingly irrelevant materials before, but he just wanted to reach a real cooperation with the US military. Only by getting financial and technical support from the U.S. military before starting research, or during the research process, can you be sure that you will be a real U.S. defense contractor.

"Of course, we don't need money."

Wen Ming smiled confidently and said: "All we need is the license to apply binary vector engine technology, of course, if we can get some mature vector engine technical information, I think our research time will be introduced 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? Also, you're working on energy engine technology, not vector engine technology. ”

Binary vector engine technology can be said to be unique to the U.S. government, and even Russia's technology in this area is inferior to that of the United States. It is precisely because of this premise 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 United States, not everyone is qualified to conduct research.

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

The technician explained to Wen Ming: "Although energy engine technology and vector engine technology are two different technologies, strictly speaking, they have a lot in common. ”
