Jiang Yanhai is not married yet, he doesn't understand this, you have to say that he understands, you can only say that Jiang Yanhai understands people's hearts, he knows that he can't say too much, he is not here to deal with these things.

Presumably after today, no one in Qiu Wenze's class should talk about him because of this incident.

Sometimes it's easy to change people's mindsets, but it's also hard.

It's okay for them to shut up with the facts, but when others choose to turn a blind eye, you don't have to fight, because such a person has prejudice in his heart from the beginning, no matter how much you say, he won't change his mind, and you can just choose to turn a blind eye to him.

There isn't much Jiang Yanhai can do, that's all.

In the teacher's office next to him, everyone else went out temporarily, and there were only four people in the room, Jiang Yanhai, Qiu Xiaofei, his children and mother.

"Auntie, little friend, what I just said is not a lie, your father is indeed a People's Liberation Army now, he made mistakes before, so he is now actively correcting his mistakes."

Jiang Yanhai squatted in front of Qiu Wenze and said seriously.

"So, your father has now become a glorious PLA soldier, and you can tell anyone that your father is a PLA soldier in the future!"

"Uncle, I see." Qiu Wenze was very well-behaved, he nodded seriously, looked at Jiang Yanhai and raised his head to look at Qiu Xiaofei.

"We're going to leave with your dad in a while, he has to carry out a secret mission, but I will ask him to send you back a few photos of himself in the army, auntie, Qiu Xiaofei's salary will be sent back to you later, it is not easy for you to bring a child by yourself, call him if there is anything, although he may not be able to answer the phone, but someone will convey it at that time." Jiang Yanhai turned to Qiu Xiaofei's mother again and spoke.

"Comrade...... Thank you...... Thank you. Qiu Xiaofei's mother couldn't cry, of course she knew what it meant.

"Xiaofei, you have to follow them and do things for the country seriously! If you make another mistake, don't come back, I don't want to see you. ”

"Mom, I see." Qiu Xiaofei also said with red eyes.

"Then let's go!" Jiang Yanhai gave a military salute to the two people, including this little friend.

Qiu Xiaofei did the same.

"Uncle, can I become a PLA like you in the future?" Qiu Wenze raised his head and looked at Jiang Yanhai and asked.

"As long as you study hard, you will definitely be able to!" Jiang Yanhai nodded seriously.

"Uncle, I know! I'll take the first place next time! Qiu Wenze nodded his little head and said.

"Come on, we all believe in you."

Coming out of the office, I thanked the teachers and the dean of academic affairs, and Jiang Yanhai and they left.

“…… Thank you, Chief. Coming out and getting into the car, Qiu Xiaofei said seriously.

"Work hard, and I hope that in the future you can come back to see them openly and honestly, instead of us people following you and monitoring you." Jiang Yanhai's tone was calm.

"Yes!"

"The hound arranges for someone to send him back."

"Yes!"

……

The affairs of the information force can be regarded as completely over, and there is no need for Jiang Yanhai to keep an eye on the rest of the matter, after getting on the right track, Black Eagle and Beichen Xiang cooperated with Fan Tianlei and other management officers in the past, and the information force has already entered the right track.

And Jiang Yanhai's vacation is officially over, he still returned to the National Defense University for the time being, it is time to attend classes, and Liu Lao has not yet informed Jiang Yanhai about the phantom drawings.

However, the phantom's shape structure wind tunnel has begun to blow, an excellent fighter shape must be considered multiple times, any practical fighter shape can not be said to be 100% perfect, but it can only be said that all its achievable performance, and then comprehensive consideration, take the most optimal choice.

There must be trade-offs.

No design can be said to be 100% perfect, not even the Phantom.

And the structural design is also related to your materials, there are some structures, when the materials are not up to the mark, even if this structure is used to make the fighter have super maneuverability, etc., but if you use it, it will directly lead to disintegration, and such a structure is naturally unreasonable at that time.

But if one day there is a material that can achieve strength and allow your fighter to adopt this design structure, then it will be perfect.

What to use mainly depends on what hole cards you have in your hand, but the preliminary results of the wind tunnel of the Phantom have come out, and this shape is already very perfect, and it is somewhat similar to J20, but overall, the rear wing is larger.

And it's also slightly larger than the J20.

I called Professor Zhao to confirm the engine, and the Phantom Engine had started multiple test tests at the same time.

A total of 10 engines have been built, and in addition to two of these 10 engines as a backup, the other eight have been subjected to various simultaneous tests at three different research institutes.

However, so far, as the first time it has been built, the engine that has been put through 150 hours of long-term start-up and test run has not yet had problems, and its overall structure, including wearing parts and load-bearing parts, is currently in good condition.

Although this has something to do with the fact that this engine is not equipped with a fighter, the problem is even so, in terms of its service life, this is the absolute first in the country at present!

Regarding this matter, Jiang Yanhai, who has returned to the National Defense University, began to argue with Professor Qian, and to be honest, when Jiang Yanhai was learning the design concept of this engine, these design schemes included a description of its stability.

But he didn't expect this stability to be so strong!

In particular, the test results of another destruction test made all the professors feel a little shocked.

For example, in the previous version of the J10S Qinglong, all J10 engines could not carry out supersonic cruise, and the standard for supersonic cruise refers to supersonic flight for more than half an hour in the state of intermediate thrust.

The J10C engine of these versions can enter supersonic speed with afterburner, and the maximum speed can reach Mach 2.5, but in the afterburner state, the engine of J10C cannot continue to output full afterburner for a maximum of 10 minutes, and 10 minutes is the limit.

In normal combat, a short range of full afterburner, a maximum of five or six minutes is already the limit.

Beyond this time, the engine will be dangerous, and you can appreciate the importance of engine life from this aspect.

At present, when the Phantom's engine is undergoing a destructive test test, its duration is a full 3 hours at full afterburner!

According to the maximum speed of Mach 4 of the Phantom Kai afterburner, the flight distance per hour is 4896 kilometers! You can fly 14,588 kilometers in 3 hours! Of course, the Phantom's fuel tank can't make it fly at full fuel for 3 hours.
