Qin Chuan knew that Qin Shuai was really conscientious, and in order to do a good job in the alliance army, he worked tirelessly, and even stayed up late to make military robots.

With him in the alliance army, he is a general, and he was a little unconvinced before, because he felt that they were the same age, but now he really admires Qin Shuai more and more.

On this day, after they cleaned up the mess of the battlefield, there was another simulation training, but there were many tasks assigned by Regiment Commander Qin, and Qin Chuan felt a little disobedient, because the training aircraft used allowed them to experiment in the same place, tossing and turning repeatedly, Qin Chuan's tired hands and feet were numb, and he finally replaced an experienced soldier to replace him.

The regimental commander even gave him a task to find the difference between a flight simulator and a trainer aircraft, and there were similarities, which he studied for a long time and did not think about the answer. But this time it was an unstoppable problem, because the prisoners they had captured before had confessed to these things, and some of their equipment was mounted on simulators and trainers, which appeared in the sky over the Coalition forces at that time, and their surveillance equipment did not even capture them.

He had to bite the bullet to find Qin Shuai, he knew that Qin Shuai had been very busy and hard these days, but these problems were generally only able to be solved by him.

He wrote down the difficult questions given to him by Regiment Commander Qin on the test board, asked his assistant to hand it over, Qin Shuai made an OK gesture for him, and after finishing some arrangements on the battlefield, Qin Shuai hurriedly analyzed him.

"Flight simulators, in fact, are a challenge for trainers," he said. Flight simulators are becoming more and more accurate and can complete a lot of training that used to have to go to the sky, but they can't replace trainers. For example, when doing dangerous maneuvers, you can come back if you fail on the simulator, but you don't necessarily have the opportunity to do it again on the plane. In addition, the flight simulator uses the same environment as the cockpit of an airplane to simulate the state of flight. The hardware is as easy to do as it is in a real airplane. But the flight characteristics are the same as those of a real aircraft, which is difficult...... Even today, with the development of technology, simulation models are still highly simplified. ”

Qin Chuan said: "...... However, I still lack a microscopic understanding of complex physical phenomena and can only describe them in general terms with simplified models. Now that I see these things assigned to me by my uncle as a regiment commander, I feel that I have learned very little, so I always want to come and ask. ”

Qin Chuan asked: "What about the real-time calculation of the weight change caused by complex weather and fuel consumption or the delivery of weapons in the flight simulator?" ”

Qin Shuai simply brought him to his own aircraft, and used the ray to make the aircraft several times larger, so that it could be observed very clearly with the human eye, he explained to him one by one, and then went up to control it himself to Qin Chuan, he said: "The wind tunnel and test flight time of modern fighters are longer than before, because people now have higher requirements. Flying higher, faster, and more aggressive, the more complex the plug-in, and the farther away from the simplified ideal state of the interaction between air and aircraft, which also makes it more difficult for flight simulators to simulate accurately. ……”

Qin Chuan simply boarded this flying machine, operated it with his hands, and with Qin Shuai's cooperation, he remotely controlled it into the air, flew it for a short time, and then slowly landed, because this had not really flown yet. For safety reasons, he was only allowed to test fly for a short time.

Qin Chuan was a little excited because of this short flight, and he asked again: "Is it okay to use the flight model in the digital wire control as a simulation model?" ”

Qin Shuai replied with a smile: "Yes, but there is a key difference between wire control and simulation, wire control is a closed-loop environment, and the error of pneumatic data estimation can be adjusted and compensated in real time through the measured feedback of the surrounding physical world,...... But emulators don't have such conditions. This is another reason why it is impossible for an emulate to replace a trainer. When the requirements are not high, the simulator can indeed replace many basic training flight hours, which makes the training aircraft only develop to the high-end, and only in the subjects that cannot be accurately simulated in the simulator can have superiority......"

"In addition to training flight cadets, these trainer aircraft used by our coalition forces have also begun to take on the task of maintaining the flight hours of veteran pilots. High-performance trainers can meet most of the requirements, and trainers with wire-controlled stabilization can also imitate a variety of aircraft, which is an entry point for high-performance trainers, but the premise is still low procurement and operating costs, otherwise it makes no sense......"

"I guess why Regiment Leader Qin would let you study this topic? I just want you to know more, and then be more exquisite in technology, and exercise your flying skills, the problem of these training aircraft used by our alliance army now is not in technology, but in how to balance cost and performance......"

Qin Chuan nodded thoughtfully, because what Qin Shuai told him was very detailed, but he was very surprised that Qin Shuai did not obtain this knowledge through systematic training, which was also something that made him unbelievable.

Maybe he is talented, maybe he was born with these abilities, Qin Chuan sometimes really admires it, and the protective cover he designed for himself, in battle, sometimes it is more effective than body armor.

Qin Shuai: "To get this knowledge, we have to use it properly, try to satisfy your uncle, he also likes you like Jackie Chan, but I am not his own nephew, you are, so I try to tell you, and then you will be enthusiastic in front of him." ”

Qin Chuan is a person who knows gratitude, but he can't bear to explore all of Qin Shuai's skills and use them for himself, and he knows that Qin Tuan actually has a hand in Qin Shuai, because he is afraid that Qin Shuai will climb on his head in the future.

But Qin Chuan is a person who looks to the future, he knows who can play the role of a leader in the future, Qin Shuai has undoubtedly played this role, so he knows why Colonel Jin is not good to Qin Shuai, he has already guessed, as if he deliberately sent Qin Shuai here as a prisoner, in fact, he just doesn't want to affect his status, and now his uncle is undoubtedly like this.

Commander Qin has never reused Qin Shuai in the real sense, but on the battlefield, it is imminent, there is no way, just like the last time Sergeant Zhang happened, his leg was lame, and he could only be replaced by Qin Shuai, but he has not been promoted yet, according to reason, he should be corrected now.
