When the missile guidance part was not developed, Jiang Xinwei felt that it was difficult to learn this thing, but it would not be too difficult.

However, after coming into contact with this information and those electronic components, he found that the difficulty of learning was far more than he imagined, and he found that missile guidance technology involves too many specialties, in addition to electronic technology, radio technology, microelectronics technology, automatic control technology, material technology, computer technology, structural mechanics, fluid mechanics, thermal energy, chemistry, and so on......

Seeing that a few days have passed, he has not mastered its essence, especially modern fluid mechanics and thermal energy are technologies that he has not been exposed to in two lifetimes, and many complex fluid mechanics equations have made it difficult for him to move an inch.

It seems very easy to use a positioning satellite to guide a missile to strike a target: Isn't it that the missile guidance part constantly accepts the data of the positioning satellite, constantly calculates its own coordinates through the computer inside, and then constantly adjusts the direction of the missile according to the coordinates of the input target?

It's easy, if you find that your direction is deviating, you immediately send yourself out, command the attitude to adjust the engine jet flame, and adjust the position to it. It is biased to the left, and the attitude adjustment engine pushes hard to the left, pushing it back to the right. It leans downwards, and the attitude engine wants to push it a little bit higher.

However, if only it were that simple, missiles could be produced.

The biggest constraint of the missile guidance part is the complete and seamless matching with the speed of the missile.

This includes two aspects:

The first aspect is that the speed of the missile is high, the time to adjust the attitude of the engine is very short, and the power of the engine must be controlled very precisely. Missiles generally reach speeds of about 1,000 kilometers per hour, and they travel nearly 300 meters per second.

Suppose a cruise missile is maneuvering at an ultra-low altitude 100 meters above the ground, as long as the attitude adjustment engine is misdirectional, it can hit the ground in just a third of a second, turning a million-dollar missile into a brilliant firework.

If you're navigating a canyon, it's more difficult to adjust left and right, and the control of time and power is more demanding.

The second aspect is that the missile flies at a faster speed, the position of the missile naturally changes faster, and the latitude, longitude and altitude change at any time. After receiving the data sent by the positioning satellite, the computer in the guidance system must calculate the latitude and longitude and altitude of the missile in a very short time, and must instantly compare it with the terrain data stored in the memory, find out the obstacles in front of it, avoid it, or jump up, turn left or right......

No matter how fast the computer is, it will take time to calculate the current position of the navigation numerical control, and the action of data comparison is the fastest, and it will also consume time to recall data from the memory and compare data, so as to find dangers and avoid obstacles.

If the missile is flying at a high altitude, it will have a little more time, maybe a few tenths of a second to wait, and even have a certain degree of fault tolerance. However, if it is a cruise missile, it will be troublesome, not to mention a delay of a few tenths of a second, even a delay of 0.00 and a second.

The delay of calculating coordinates and other position data is 0.001 seconds, and the delay of comparing terrain data is 0.001 meters, which adds up to 0.002 seconds, not to mention other signal delays and attitude adjustment engine action delays, it is this 0.002 seconds that the missile can deviate by more than six meters. You were aiming for the first window in the east, but you hit the third window in the east!

It is precisely because missiles have such strict time requirements that ordinary computers cannot meet the requirements at all, and this is why there are many countries in the world that understand the principles of cruise missiles, and almost every country has military technical experts who understand them, but only a few countries can produce them.

Jiang Xinwei wanted to design the missile guidance part, not only to select processor chips with excellent performance, but also to rigidly pick out the design circuits, to cut out the time delayed by each part of the circuit, to carefully think about their logical relationships, to make the logical relationships as smooth and concise as possible, and to minimize some unnecessary logical operations so as to reduce time consumption.

These designs require an exceptionally clear brain, a scientific overall plan for the overall situation, and the impact on every detail, every negative feedback, and every parameter adjustment...... You all know it all.

The thinking and brainpower of ordinary people are simply not up to the task.

……

Jiang Xinwei, whose research and development was blocked, had to play a game according to her wishes under the persuasion of Mayoni, to see if his learning progress could be accelerated.

Jiang Xinwei is also willing to participate in this match, not only because he is a bit addicted to playing football now, not to mention that he can also improve the thinking efficiency of his brain, but also because the youth team of Colosio is preparing to play a match against the youth team of Juventus.

Although the Juventus team and the Juventus youth team are completely different concepts, Jiang Xinwei still wants to play with them, and he liked the Juventus team very much in his last life.

East-JM Investment's impact on the Kolosio youth team is huge, although the starting lineup of the Kolosio youth team has been announced, the coaching staff temporarily added Jiang Xinwei's name (Wang Guopeng), and they also arranged Jiang Shige, who knows Jiang Xinwei, to the bench.

When Jiang Xinwei arrived at the stadium in the car arranged by Mayoni, the players were warming up.

Seeing Jiang Xinwei, Jiang Shige took the initiative to greet him: "Wang Guopeng——!!

Jiang Xinwei was stunned, he didn't expect Jiang Shige to call himself by this name directly, maybe this was the reason why he took the initiative to say hello, but he knew that Jiang Shige was not a person who liked to talk.

Jiang Xinxu walked over to him with a smile and asked, "Why are you here too?"

Jiang Shige was also stunned, and asked in surprise: "Didn't you introduce it?" It said that you persuaded the owner of the Kolosio Youth Team, so I ...... it."

Jiang Xinwei was a little foggy, but he didn't say anything more, but asked with a smile: "How is it?

Jiang Shige smiled bitterly and said, "It's nothing else, it's just that the language is a little ...... , though, it's okay, the players and the coaching staff are good to me, and they don't treat me equally. ”

After chatting a little, head coach Lasvali came over, hugged Jiang Xinwei, said a few words of welcome, and arranged for Jiang Xinwei to warm up.

Rasvali also knows that Jiang Xinwei has too many mysteries, and there is no need to say too much, as long as he can bring a steady stream of funds to the team and the club. Now Jiang Xinwei, Jiang Shige, and Xie Jianfeng, the three players from Huaxia, do not have high salaries, and the highest is Xie Jianfeng, who came to the door by himself, but it is only 3,000 US dollars a month, which is the price of cabbage at all.
