alien heir

Due to the strong measures taken by the government, the parents of the students gathered to besiege the school came and went quickly.

Although this may cause many people to resent, so that they say more bad things and rumors about free schools on the Internet, this can only be spread on the Internet. Those who really understand the truth, or those who enjoy the benefits, are Don't care about these.

Moreover, as time goes by, as long as you learn to implement your established policies unswervingly, no matter what everyone says or thinks, slowly, many people will change their minds.

In this way, the online discussions about these two schools continued, involving various aspects, but in the end, the main discussion became whether the school’s policies are good, right, whether this kind of blindly favoring poor children can really help? Let the children of the poor become talents and other topics.

Basically, many low-income people agree with this and think it is a good thing, but it is a pity that the number of schools is too small, while those experts and scholars are just the opposite. They all think that this is too cost-effective and not worth promoting.

In the opinion of many experts and scholars, no matter whether the children of the poor or the rich, the success rate is not high, and only the children of the middle class are more likely to become talents. If this is the case, such high-standard schools should give priority to middle-class students. Class inclination is right, so that more useful talents can be sent to the country, and those high-standard facilities and educational resources can be fully utilized.

Without exception, these statements of the experts were unanimously reviled by most people, but they 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 the Chinese Communist Party and listen to what they want.

In fact, the batch of high-performance new materials that Cheng Yuan imported to Huaguo before did not help Huaguo's domestic use much.Because that batch of materials was basically covered by the military, or the major enterprises and scientific research institutions under the military.

Due to the excellent performance, this batch of materials can be said to have strong applicability in various aspects, such as tank armor, aircraft fuselage materials, engine materials, etc. After applying these materials, a huge leap.

However, the military-affiliated enterprises and research institutes have always been overstaffed.Research is notoriously slow. When the military's subordinate factories obtained these new materials and were still studying the possible application of these materials in the military field, they suddenly heard that the Swedish Saab company had developed a fifth-generation fighter.

As we all know, although all countries are now developing fifth-generation fighters, to be honest, the only ones that can be said to be fifth-generation fighters and are in service are the F22 and F35 of the United States.The fifth-generation aircraft in other countries are basically still in the state of research and development, and it is impossible to say that they have been developed, and there is no actual equipment.

Sweden has also heard that it is developing a fifth-generation aircraft.However, due to limited national power, the progress has been very slow, and it belongs to a series that has been neglected, but now it suddenly happened at the Shanghai International Air Show held in Shanghai, China just now.The practical model of the fifth-generation machine was launched, and its ultra-high performance and parameters immediately attracted the attention of all countries.

Of course, Hua Guo also paid attention to this.

The fifth-generation machine launched by Saab this time.There are two types, 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, like the f-22 and f35, they are also two types of aircraft with high and low levels, or in other words, they are Both heavy and light fifth-generation jets.

Both aircraft have super stealth capabilities, supersonic travel capabilities, and powerful avionics systems and radar systems.That’s all. After all, the fifth-generation fighters focus on these things, but whether it’s the big crow or the little crow fighter, its parameters and performance are all over the f22, and it has become the world’s strongest aircraft in one fell swoop. This is what attracts people’s attention. .

Take the jas-45 and the Raven aircraft as an example. The surface of this aircraft looks like a thin black triangle, with a full wing-body fusion design, which is full of sci-fi.Due to the use of a large amount of carbon fiber and new nano-composite materials, carbon fiber, graphene and nano-composite materials account for more than 90.00% of the body, so that the empty weight is only 9.5 tons, only half of the F22, but the maximum take-off weight has reached 38%. 22 tons, fully exploded f[-], which means that more weapons and equipment can be carried.

In addition, the Raven aircraft adopts four-engine mode, two new intelligent variable-cycle engines, and two intelligent scramjet engines, so as to solve subsonic and supersonic flight.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, and the speed can be changed freely while taking into account the economy and practicality.

The firepower is not weak. In fact, since the take-off weight reaches 38 tons, it means that more weapons can be installed. After all, the empty weight of the aircraft is removed, which means that the Raven aircraft can carry an additional weight of 28.5 tons. Excluding personnel, at least It can carry 28 tons of weapons and ammunition, which has surpassed the American b-52, and can be used as a heavy bomber.

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

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

During the pilot driving process, there are three modes, namely manual mode, semi-automatic mode and fully automatic mode.Manual mode is fully manual operation of the aircraft. This 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 controls, such as helping the pilot to correct some flight parameters, or helping the pilot to lock fire and avoid missiles Waiting, it means that the pilot has a reliable partner to help; the fully automatic mode means that the pilot completely ignores the aircraft and allows the aircraft to fly completely automatically. This is generally in non-combat mode, which can reduce pilot fatigue.

In terms of human-computer 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. The pilot can chat with the plane like an old friend, and give orders to the plane through voice commands, which increases the speed of command execution. Avoid the rush of hands and feet in critical situations.

The safety aspect is also very good. Because the aircraft itself uses nanocomposite materials and carbon fiber graphene and other materials, it has a strong impact resistance, and it is a last resort.Skydiving is also possible.

The big crow's skydiving method is the cockpit separation skydiving, that is, the entire cockpit is ejected from the aircraft to avoid additional impact.When the cockpit is ejected and the parachute is opened, the seat ejection parachute can be performed from the cockpit in a critical moment to protect the life of the pilot to the greatest extent.

In addition to having powerful power, firepower, avionics and safety, the Raven aircraft also has a strong stealth ability, which is also something everyone talks about.It is recognized as the aircraft with the strongest stealth ability among all stealth aircrafts at present.

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 supermaterial stealth coating of the aircraft, and the plasma stealth technology.Carry out all-round intelligent stealth to the aircraft.This method can not only avoid radar, infrared and other electronic detection, but also can perform visual stealth because of the zero-refractive index metamaterial stealth coating.The so-called visual stealth is said.It can disappear directly in front of people's eyes. If you don't walk in and take a closer look, you won't even notice that there is an airplane in front of you!

In fact, this zero-refractive index metamaterial.Countries have already begun research. For example, the new invisibility cloak that the United States is investing in research and development is made of this material, so that people can disappear directly, and it is impossible to find it without walking in. However, it has never been used on large machinery, such as airplanes. used.

In other words, most countries around the world have a concept of this kind of zero-refractive-index metamaterial, and very few people have fully mastered this technology, let alone applied it to high-speed moving aircraft. Generally speaking, it is considered a A new type of nanotechnology.

The basic parameters of the little crow are similar to those of the big crow, except that it is a little lighter than the big crow, with an empty weight of only 3.5 tons. In addition, the engine is a single-engine variable-cycle engine with a maximum take-off weight of only 9 tons and a maximum speed of Mach 3.2.However, the little crow can implement vertical take-off and landing, and the ammunition load is also good. The key is that the price is much cheaper, and the price/performance ratio is extremely high.

Of course, the above are all data parameters. If you blow it up, anyone can do it, but the problem is that people in Sweden don’t just blow it up, they actually build things to participate in the air show. After they come, they don’t just put them there for people to see. Then let’s talk about the data, but actually let the pilot fly the plane into the sky, so that everyone can observe the actual flight data of this plane in all directions.

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

Such a good aircraft, countries are naturally very tempted, not only many countries began to ask 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 aircraft technology known as the fifth and a half generations, but they don't have too much hope for this. Therefore, what the Chinese government hopes most is to be able to purchase a few aircraft, and then continue to use the characteristics of Huaguo to carry out reverse research and development.

Because according to the scientific researchers in Huaguo, the key to the advancement of this aircraft is the use of a lot of new materials, not to mention the supermaterials, but other materials, in fact, imported carbon fibers, graphene, etc. All 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 aircraft. After all, although Batumi is gone, the NATO group led by the United States basically restricts the export of military facilities to China. However, considering that Sweden is not a member of NATO and is a neutral country, So if the relationship is in place, it is not impossible to buy their aircraft.

After much deliberation, the Huaguo government thought of Cheng Yuan, hoping to use Cheng Yuan's line to discuss the issue of aircraft technology cooperation. Of course, if the introduction of technology fails, it is best to buy a few aircraft to come in. In terms of price easy to talk.

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

You know, if the state sends personnel to discuss the purchase of the plane, it will be very troublesome and attract too much attention. Instead, it is better to let a private person buy the plane first, and then the state finds a name to buy the plane from the private person.

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

If it weren't for this intention, the Huaguo government would not have let the local government protect Cheng Yuan in the first place, and dispatched riot police and armed police soldiers, especially the armed police, it would not be as simple as dispatching the police.

In fact, Cheng Yuan only knew about the new plane not long ago.

Vivienne bought all the way in the beginning, and bought almost all the famous large companies in Sweden. After the acquisition, the company has carried out a series of optimization and integration, increased the capital investment in various research institutions, and some geniuses The selfless dedication of the apprentice scientific and technological workers, as well as the application of a large number of new materials, made the Swedish fighter, which was already in the state of research and development, feel like a chicken blood, and made breakthroughs in various research fields. Finally, with the help of Xiaolan , creating a fifth-generation aircraft in the true sense.

After the aircraft was built, it happened that Huaguo held an air show, so although this new aircraft did not make an appointment in advance, because of its excellent performance, it temporarily jumped in the queue and entered the air show. In a remote corner, it was used The incomparable elegant shape and incomparable performance parameters surpassed all other aircrafts and became the well-deserved first star of this air show!

Afterwards, the two prototypes conducted actual flights again, using real data to defeat everyone's speculation, and once again verified that the throne of the first aircraft was well deserved.

It was at this time that Cheng Yuan got the news that this aircraft was produced by his subsidiary company, and they all came to participate in the exhibition.

No way, who made Cheng Yuan too busy recently to pay attention to these things at all, and even if he pays attention to research and development, he pays more attention to the Coron Islands base and the affairs of Louis, and rarely pays attention to Sweden, let alone Too much attention is paid to the performance of those companies that belong to Vivienne.

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

This crow fighter is it. (To be continued..)
