Due to the strong measures taken by the political axe department, the gathering of students' parents to besiege the school came and went quickly.

Although this may cause many people to resent and say more bad things and rumors about free schools on the Internet, it can only be circulated on the Internet, and people who really understand things, or people who enjoy the benefits, will not care about this.

And, as time goes by, as long as you learn to unswervingly implement your own established policies, then no matter what everyone says or thinks now, slowly, many people will change.

In this way, the discussion about these two schools on the Internet continues, involving all aspects, but in the end, the main discussion becomes whether the school's policy is good or not, right, whether this kind of blind favoritism to help poor children can really make poor children become talents, and other topics.

Basically, many low-income people still agree with this, thinking that this is a good thing, but unfortunately the number of schools is too small, and those experts and scholars are the opposite, they all think that this is too low to be promoted.

In the opinion of many experts and scholars, whether it is the children of the poor or the children of the rich, the success rate is not high, and only the children of the middle class are more likely to become talents, so in this case, such a high-standard school should give priority to the middle class, so as to send more useful talents to the country and make full use of those high-standard facilities and educational resources.

Without exception, these statements by experts have been unanimously abused by most people, but they have attracted a lot of firepower.

But these things basically have nothing to do with Cheng Yuan, and he doesn't care what others think, what he is doing now is to receive the people sent by Hua [***] Fang and listen to what they want.

In fact, Cheng Yuan's previous import of new materials with the surname Gao Neng to Huaguo did not help much for the Chinese people, because those materials were basically covered by the military, or the major enterprises and scientific research institutions under the military.

Because the surname can be so good, so this batch of materials can be said to have a strong application in all aspects, such as tank armor, aircraft fuselage materials, engine materials, etc., after the application of these materials, can immediately produce a huge leap.

However, the military's affiliated enterprises and research institutes, which have always been known for their bloated institutions and slow research, suddenly heard that the Swedish company Saab had developed a fifth-generation fighter when they got these new materials from their factories and were still studying their possible applications in the military field.

As we all know, although all countries are now developing fifth-generation fighters, to be honest, at present, it can really be said that they are fifth-generation aircraft, and those in service are only the F22 and F35 of the United States, and the fifth-generation aircraft of other countries are basically still in a state of research and development.

Sweden has also heard that it is developing the fifth-generation aircraft before, but it is limited by national strength, so the progress has been very slow, and it belongs to a series that has been neglected, but now suddenly at the Shanghai International Air Show held in Beijing, China, the practical model of the fifth-generation aircraft was launched.

Of course, there is also the attention of Huaguo.

There are two kinds of fifth-generation aircraft launched by Saab this time, one is the JAS-45 fighter, commonly known as the Big Crow, and the other is the SASB-55 fighter, commonly known as the Little Crow, which is the same as the F-22 and F35, and it is also two kinds of aircraft with high and low combinations, or in other words, it is a heavy and light two fifth-generation jets.

Both aircraft are capable of stealth, supersonic speed, and powerful avionics and radar systems. These things are just that, after all, the fifth-generation aircraft is to pay attention to these, but whether it is a big crow or a small crow fighter, its various parameters can completely explode F22 and become the strongest aircraft in the world in one fell swoop, which is what makes people pay attention.

Take the JAS-45, the Big Raven aircraft as an example, this kind of aircraft looks like a thin black triangle on the surface, with a full wing body fusion design, full of science fiction. Due to the use of a large number of carbon fiber and new nano composite materials, carbon fiber, graphene and nano composites account for more than 95 percent of their own use, so that the empty weight is only 9.5 tons, only half of the F22, but the maximum take-off weight has reached 38 tons, the complete explosion of F22, which means that it can carry more weapons and equipment.

In addition, the Big Raven aircraft adopts a four-engine mode, two new intelligent variable-cycle engines, and two intelligent scramjet engine units, so as to solve subsonic and supersonic navigation. After adopting this mode, the actual maximum speed can reach Mach 5.2, the maximum range is 5100 kilometers, the combat radius is 2100 kilometers, and the practical ceiling is 24200 meters.

The firepower is not weak, in fact, because the take-off weight reaches 38 tons, it means that it can be loaded with more weapons, after all, excluding the empty weight of the aircraft, this means that the Big Raven aircraft can carry an additional weight of 28.5 tons, excluding personnel, at least 28 tons of weapons and ammunition can be mounted, which has surpassed the American B-52, and can be used as a heavy bomber.

In fact, in order to maintain stealth as much as possible, the Big Raven aircraft adopts a fully built-in weapon scheme, and inherits the multi-purpose concept of its predecessors, which can be loaded with various weapons, such as air, ground, and sea missiles, and all kinds of aerial bombs are inside the cabin, and the hatch is opened when needed. In addition to this, there is a built-in laser launcher and two built-in six-barreled Gatling cannons.

The avionics system of the Big Raven is also very advanced, the Big Raven aircraft uses a new radar and a variety of sensors, and a new computer and a new artificial intelligence program are installed inside, which can detect the surrounding situation in real time and correct their flight data.

During pilot driving, there are three modes, which are manual mode, semi-automatic mode, as well as fully automatic mode. The manual mode is to use the aircraft manually, which can be a mandatory mode to give full play to the pilot's personal ability; Semi-automatic mode means that the aircraft has certain intelligent control, such as helping the pilot correct some flight parameters, or helping the pilot to carry out fire locking, anti-missile evasion, etc., which is equivalent to allowing the pilot to have a reliable partner to help; The fully automatic mode means that the pilot completely ignores the aircraft and makes the aircraft fully autonomous, which is generally in non-combat mode, which can reduce the fatigue of the pilot.

In terms of human-machine communication, the touch screen and voice dialogue capabilities are adopted, that is, in addition to the traditional touch screen, it also has a voice recognition function, and the pilot can chat with the aircraft like an old friend, and give orders to the aircraft through voice commands, which increases the speed of command execution and avoids the rush in critical situations.

The safety aspect is also very good, because the aircraft itself uses nano composite materials and carbon fiber graphene and other materials, the impact resistance is very strong, and no matter what is necessary, you can also parachute.

The big crow's skydiving method is a cockpit split skydive, that is, the cockpit is ejected from the plane in its entirety, avoiding additional shocks. When the cockpit is ejected out and the parachute is opened, the seat can be ejected from the cockpit at a critical moment to protect the pilot's life to the greatest extent.

In addition to having strong power, firepower, avionics and safety, the Big Crow aircraft also has a strong stealth ability, which is also talked about by everyone, and is recognized as the strongest stealth aircraft among all the stealth aircraft.

The stealth method of this aircraft adopts a new intelligent comprehensive stealth method. That is to say, from the stealth design layout of the aircraft, the metamaterial stealth coating of the aircraft and the plasma stealth technology, etc., the aircraft is fully intelligent stealth. This method can not only avoid radar, infrared and other electronic detection, but also because of the zero refractive index metamaterial stealth coating, it can also carry out visual stealth. The so-called visual stealth means that it can disappear directly in front of people's eyes, and if you don't walk in and take a closer look, you won't find that there is an airplane in front of you!

In fact, this kind of zero-refractive index metamaterial, countries have begun to study, such as the new type of invisibility suit that the United States is investing in research and development, is the use of this material, so that people can disappear directly, and they can't find it without walking in, but it has never been used in large machinery, such as airplanes.

In other words, this zero-refractive index metamaterial, at present, most countries have a concept, and very few people have really fully mastered this technology, let alone applied it to high-speed moving aircraft, generally speaking, it is considered to be a new type of nanotechnology.

The basic parameters of the small crow are similar to those of the big crow, but it is a little lighter than the big crow, with an empty weight of only 3.5 tons, and the engine is a single-engine variable cycle engine, with a maximum take-off weight of only 9 tons and a maximum speed of only Mach 3.2. However, the little crow can implement vertical take-off and landing, and the bomb load is also good, the key is that the price is much cheaper, the surname price is better than the complete explosion F35, which is considered to be a high and low match with the big crow, and as the first choice for aircraft carriers and carrier-based aircraft.

Of course, the above are all data parameters, if you blow, anyone will, but the problem is that Sweden is not just blowing, it is really making things to participate in the air show, and after coming, it is not just there for people to see, and then talk about the data on the side, but really let the pilot fly the plane into the sky, so that everyone can observe the actual flight data of this kind of aircraft in all directions.

It is this kind of actual observation that makes countries stunned and express their admiration for Sweden's usual quiet and blockbuster movement. Many military experts believe that this kind of high-power, high-firepower, high-stealth, and high-intelligence aircraft has surpassed the model of fifth-generation aircraft and should be counted as a fifth-and-a-half-generation aircraft.

Such a good aircraft, countries are naturally very tempted, not only many countries began to inquire about the purchase price, but also many countries hope to introduce technology.

For Huaguo, it is of course best to introduce this kind of ultra-advanced, known as the technology of the fifth and a half generations of aircraft, but they will not expect too much for this, after all, this kind of advanced fighter will generally not leak the technology, so what Hua [***] hopes most is to buy a few aircraft, and then continue to give full play to Huaguo's characteristics and carry out reverse research and development.

Because according to Huaguo's scientific researchers, the key reason why this kind of aircraft is advanced is that a lot of new materials are used, not to mention the metamaterials, but other materials, in fact, imported carbon fiber, graphene, etc., can be applied to it, as long as there is a prototype for them to carefully develop, there should be a breakthrough.

In fact, China did not have the idea of buying planes, after all, although Batumi is gone, the NATO bloc led by the United States basically restricts the export of military facilities to China, but considering that Sweden is not a member of NATO and is a neutral country, it is not impossible to buy their planes if the relationship is in place.

Hua Guozheng thought about it, and thought of Cheng Yuan, hoping to use Cheng Yuan's line to talk about the issue of aircraft technical cooperation, of course, if the introduction of technology fails, it is best to buy a few planes to come in, and the price is easy to speak.

In this way, the military specially sent a lieutenant general to lead the matter and personally find Cheng Yuan to talk about this matter. In fact, their plan is not bad, that is, they hope to let Cheng Yuan be the intermediary, and the negotiation is the best, and it doesn't matter if the negotiation fails, it will not cause too much repercussions from other countries.

You know, if the state sends personnel to talk about the purchase of the plane, it will be very troublesome and too attention-grabbing, but it is better to let a private person buy the plane first, and then the state will find a name to buy the plane with the private person.

For example, the first aircraft carrier of Xinhua, isn't that how it came about.

If it weren't for this thought, Hua Guozheng would not have let the local government protect Cheng Yuan for the first time, so quickly dispatched riot police and armed police soldiers, especially armed police, it was not as simple as dispatching police.

In fact, Cheng Yuan only knew about the new plane for a short time.

Vivian acquired all the way to Sweden's almost famous large companies, and the acquired company due to a series of optimization and integration, increased capital investment in various research institutions, coupled with the selfless dedication of some genius disciple science and technology workers, and the application of a large number of new materials, which made the Swedish fighter in the original state of research and development seem to have been beaten, and all aspects of research have been constantly breaking through, and finally, with the help of Xiaolan, a real fifth-generation aircraft was created.

After the plane was built, it happened to meet Huaguo to hold an air show, so although this new plane did not make an appointment in advance, but because the surname can be too good, it also temporarily cut the queue and entered the air show, in a remote corner, with its incomparable elegant shape, and unparalleled surname energy parameters, completely exploded all other aircraft, and became the first star of this air show!

After that, the two prototypes made an actual flight, using real data, defeating everyone's guesses and once again proving that they deserved the throne of the first aircraft.

It was at this time that Cheng Yuan got the news that he knew that this aircraft was produced by his own subordinate company, and they all came to the exhibition.

There's no way, who made Cheng Yuan too busy lately, and he didn't have time to pay attention to these things, and even if he paid attention to R&D, he paid more attention to the Coron Islands base and Louis's affairs, and rarely paid attention to Sweden, let alone what kind of performance the companies belonging to Vivian's subordinates had.

But now it seems that those ordinary scientific research institutions, those large companies with a long history, the strength should not be underestimated, as long as they are given sufficient funds and good enough materials, they can immediately surprise you.

That's it. (To be continued.) )
