Due to the strong measures taken by the government departments, the incidents of students and parents gathering in crowds to besiege schools came and went quickly. Although this may make many people resentful and even say more bad things and rumors about free schools on the Internet, these can only be circulated on the Internet. People who really understand the truth, or those who enjoy the benefits, are Don't care about this. And, as time goes by, as long as you learn to unswervingly implement your established policies, no matter what everyone says or thinks now, slowly many people will change their minds. In this way, the discussion about these two schools on the Internet continues, involving various aspects, but in the end, the main discussion becomes whether the school's policy is good or not, is it true that this kind of blindly favoring poor children can really help them? Let poor children become talented 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. However, 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, the success rates of children from poor people and rich people are not high, and only middle-class children are more likely to become successful. In this case, schools with high standards like this should give priority to middle-class students. Class tilt is the only way to provide more useful talents to the country and make full use of high-standard facilities and educational resources. Without exception, these statements made by experts have been unanimously reviled by most people, which has 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 people sent by the Chinese government and listen to what their requirements are. In fact, the batch of high-performance new materials that Cheng Yuan imported to China did not help China¡¯s civilian sector much. Because that batch of materials was basically covered by the military, or major enterprises and scientific research institutions affiliated to the military. Because the performance is so good, 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 product can be produced immediately. leap. However, military-affiliated enterprises and research institutes have always been bloated. Research is known to be slow. Just when the military's affiliated factories obtained these new materials and were still studying the possible applications of these materials in the military field, they suddenly heard that the Swedish Saab company had developed a fifth-generation fighter jet. As we all know, although all countries are now developing fifth-generation fighters, to be honest, the only ones that can really be said to be fifth-generation fighters and are in service are the American F22 and F35. The fifth-generation aircraft in other countries are basically still in the state of research and development. 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, limited by national strength, progress has been very slow, and it is a neglected series, but now suddenly at the Shangjing International Air Show held in Shangjing, China. The practical model of the fifth-generation machine was launched, and its ultra-high performance and parameters immediately attracted the attention of various countries. Of course, China also pays attention to this. The fifth-generation aircraft launched by Saab this time. There are two types, one is the JAS-45 fighter jet, commonly known as the Big Crow, and the other is the SASB-55 fighter jet, commonly known as the Little Crow. Like the F-22 and F35, they are also two types of aircraft with high and low configurations, or in other words, There are two types of fifth-generation jet aircraft, heavy and light. Both aircraft have super stealth capabilities, the ability to travel at supersonic speeds, and powerful avionics and radar systems. That's all. After all, fifth-generation aircraft focus on these things, but whether it is the Big Crow or the Little Crow fighter, its parameter performance completely surpasses the F22, and it has become the most powerful aircraft in the world in one fell swoop. This is what attracts people's attention. . Take the JAS-45, the Crow aircraft, as an example. This aircraft looks like a thin black triangle on the surface, with a full-wing body fusion design, which is full of science fiction. Due to the use of a large amount of carbon fiber and new nanocomposite materials, carbon fiber, graphene and nanocomposite materials account for more than 95% of the body weight, making the empty weight only 9.5 tons, only half of the F22, but the maximum take-off weight But it reached 38 tons, which was completely destroyed by the F22, which means that it can carry more weapons and equipment. In addition, the Raven aircraft adopts a four-engine mode, two new intelligent variable-cycle engines, and two intelligent scramjet engines, thereby enabling subsonic and supersonic navigation. After adopting this mode, the actual maximum speed can reach Mach 5.2, the maximum range is 5,100 kilometers, the combat radius is 2,100 kilometers, and the practical ceiling is 24,200 meters. It can freely change speed while taking into account economy and practicality. It is not weak in terms of firepower. In fact, since the take-off weight reaches 38 tons, it means that more weapons can be installed. After all,Excluding the empty weight of the aircraft, this means that the Raven aircraft can carry an additional weight of 28.5 tons. Excluding personnel, it can carry at least 28 tons of weapons and ammunition, which has exceeded the American B-52 and can be regarded as a heavy-duty aircraft. Bomber. In actual situations, in order to maintain stealth as much as possible, the Raven aircraft adopts a fully built-in weapons solution and inherits the multi-purpose concept of its predecessors. It can be loaded with various weapons, such as anti-air, anti-ground, and anti-sea missiles. Aerial bombs are all inside the cabin, and the hatch is opened when necessary. In addition, it is also equipped with 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 new radar and a variety of sensors. It also has a new computer and a new artificial intelligence program installed inside, which can detect the surrounding situation in real time and correct its own flight data. During the pilot's driving process, there are three modes, namely manual mode, semi-automatic mode and fully automatic mode. Manual mode means fully manual operation of the aircraft. This can be a forced mode to give full play to the pilot's personal abilities; semi-automatic mode means that the aircraft has certain intelligent control, such as helping the pilot correct some flight parameters, or helping the pilot perform fire locking and anti-missile evasion. Waiting, is equivalent to giving the pilot a reliable partner to help; the fully automatic mode means that the pilot completely ignores the aircraft and allows the aircraft to drive completely automatically. This is usually in non-combat mode and can reduce the pilot's fatigue. In terms of human-machine communication. It uses a touch screen and voice conversation capabilities, that is, in addition to the traditional touch display screen, it also has a voice recognition function. The pilot can chat with the aircraft like old friends and give orders to the aircraft through voice commands, which increases the execution speed of commands. This avoids the rush in critical situations. Safety is also very good. Because the aircraft itself uses nanocomposite materials, carbon fiber graphene and other materials, it has strong impact resistance, even if it is a last resort. Skydiving is also available. The method of skydiving in Big Crow is cockpit-separated skydiving, which means the entire cockpit is ejected from the aircraft to avoid additional impact. When ejecting from the cockpit and opening the parachute, you can also perform seat ejection parachuting from the cockpit in critical moments to protect the pilot's life to the maximum extent. In addition to its powerful power, firepower, avionics and safety, the Raven aircraft also has powerful stealth capabilities. This stealth capability is also talked about by everyone. It is recognized as the aircraft with the strongest stealth capability among all current stealth aircraft. The stealth method of this aircraft adopts a new intelligent comprehensive stealth method. That is to say, from the aircraft¡¯s stealth design layout, the aircraft¡¯s metamaterial stealth coating and plasma stealth technology, etc. Implement all-round intelligent stealth for aircraft. This method can not only avoid radar, infrared and other electronic detection, but also can achieve visual stealth because of the zero-refractive index metamaterial stealth coating. The so-called visual invisibility means. It can disappear directly in front of people's eyes. If you don't step in and take a closer look, you won't even notice that there is an airplane in front of you! ??In fact, this is a metamaterial with zero refractive index. Various countries have begun research. For example, the new invisibility cloak that the United States is investing in research and development uses this kind of material, so that people can disappear directly and cannot be found without walking in. However, it has never been used on large machinery, such as airplanes. Used. In other words, this kind of zero-refractive index metamaterial currently has a concept in most countries. Very few people have fully mastered this technology, let alone applying 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, the maximum take-off weight is only 9 tons, and the top speed is only Mach 3.2. However, the Little Crow can take off and land vertically and has a good bomb load. The key is that it is much cheaper and has a better price-performance ratio than the F35. It is considered to be a high-level match with the Big Crow and the first choice as an aircraft carrier-based aircraft. Of course, the above are all data parameters. Anyone can brag about it. But the problem is that Sweden doesn¡¯t just brag about it. It actually builds things and participates in air shows. After arriving, it doesn¡¯t just put them there for people to see. Then while talking about data, we actually let the pilot fly the aircraft into the sky, so that everyone can observe the actual flight data of this aircraft in an all-round way. It is this kind of actual observation that makes all countries dumbfounded, and they all express their admiration for Sweden's usual calmness and sudden move. Many military experts believe that this kind of aircraft with high power, high firepower, high stealth, and high intelligence has surpassed the fifth-generation aircraft model and should be counted as a fifth-and-a-half-generation aircraft. With such a good aircraft, countries are naturally very tempted. Not only do many countries start to inquire about the purchase price, but also many countries start to inquire about the purchase price.?The country wants to introduce technology. For China, the best thing is to introduce the technology of this ultra-advanced aircraft, which is known as the fifth-and-a-half-generation aircraft. However, they do not expect too much from this. After all, such advanced fighters generally do not export technology. It's leaked, so what China hopes most is to purchase a few aircraft, and then continue to use China's characteristics and conduct reverse research and development. Because according to Chinese scientific researchers, the key reason why this kind of aircraft is advanced is that it uses many new materials. Let¡¯s not talk about metamaterials, 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 originally had no idea of ??purchasing aircraft. After all, although Batumi is gone, the NATO group headed 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 may not be impossible to buy their aircraft. After much deliberation, the Chinese government thought of Cheng Yuan. It hoped to use Cheng Yuan to discuss aircraft technology cooperation. Of course, if the introduction of technology failed, it would be best to buy a few aircraft. In terms of price, Easy to talk to. In this way, the military specially sent a lieutenant general to personally find Cheng Yuan to discuss the matter. In fact, their plan is not bad. They just hope that Cheng Yuan will be the middleman and the negotiation will be the best. It doesn't matter if the negotiation fails, and it will not cause too much repercussions from other countries. You know, if the state sends personnel to discuss the purchase of an airplane, it will be very troublesome and attract too much attention. Instead, it is better to let a private person buy the airplane first, and then the state will find a name to buy the airplane from the private person. For example, Xinhua¡¯s first aircraft carrier, isn¡¯t that how it came about? ¡°If it hadn¡¯t been for this intention, the Chinese government would not have asked the local authorities to protect Cheng Yuan as soon as possible, and would have dispatched riot police and armed police soldiers so quickly. Especially the armed police, it would not be as simple as dispatching the police. In fact, Cheng Yuan only knew about the new aircraft not long ago. Vivian made acquisitions along the way and acquired almost all the well-known large companies in Sweden. After the acquisition, the company carried out a series of optimization and integration, increased investment in various research institutions, and added some geniuses. The selfless dedication of the disciples' scientific workers and the application of a large number of new materials made the Swedish fighter jet, which was already in the state of research and development, seem to have been given a boost. Breakthroughs continued in all aspects of research. Finally, with the help of Xiaolan, , creating a true fifth-generation aircraft. After the aircraft was built, it happened to be an air show held in China. Therefore, although this newly appeared aircraft did not have a reservation in advance, due to its excellent performance, it temporarily jumped in the queue and entered the air show. In a remote corner, I used it. Its unparalleled elegant shape and unparalleled performance parameters surpassed all other aircraft and became the well-deserved first star of this air show! After that, the two prototypes conducted actual flights. Using real data, they defeated everyone¡¯s guesses and once again verified that they deserved their title as the number one aircraft. It was at this time that Cheng Yuan got the news that this aircraft was produced by one of his subordinate companies, and they all came to participate in the exhibition. No way, Cheng Yuan has been too busy recently and has no time to pay attention to these things. Even if he pays attention to research and development, he pays more attention to the Cologne Islands base and Louis' affairs, rarely paying attention to Sweden, let alone Too much attention is paid to the performance of the companies under Vivian. But now it seems that the strength of those ordinary people¡¯s scientific research institutions and those large companies with a long history cannot be underestimated. As long as you give them sufficient funds and good enough materials, they can immediately surprise you. This is the Raven fighter.
