Chapter 886 The Second Step (Guaranteed Monthly Ticket 3)
Jiang Yanhai is not married yet, he doesn't understand this, you have to say he understands, only Jiang Yanhai understands people's hearts, he knows 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 will talk about him because of this.
Sometimes it's easy but hard to change people's perceptions.
It's enough for them to shut up, but when others choose to turn a blind eye, you don't have to fight, because such people are prejudiced in their hearts from the beginning, and no matter how much you say, they won't change. His thoughts, you can choose to turn a blind eye to him.
There's not much Jiang Yanhai can do, that's all.
In the teacher's office next to him, everyone else went out for the time being. There were only four people in the room, Jiang Yanhai, Qiu Xiaofei, and his children and mother.
"Auntie, little friend, what I just said is not a lie. Your father is indeed a member of the 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 dad is now a glorious PLA soldier, and you can tell anyone that your dad is a PLA soldier in the future!"
"Uncle, I see." Qiu Wenze was very good, he nodded seriously, looked at Jiang Yanhai and looked up at Qiu Xiaofei.
"We're going to leave with your father in a while, he's going to carry out a secret mission, but I'll ask him to send you back a few pictures from the army, Auntie, Qiu Xiaofei's salary will be sent back to you later, you yourself It's not easy to bring a child, call him if there is anything, although he may not be able to answer the phone, but someone will relay it." Jiang Yanhai turned to Qiu Xiaofei's mother and said.
"Comrade...Thank you...Thank you." Qiu Xiaofei's mother burst into tears, of course she knew what it meant.
"Xiaofei, you have to follow them and serve the country seriously! If you make mistakes again, don't come back. I don't want to see you anymore."
"Mom, I see." Qiu Xiaofei also said with red eyes.
"Then let's go!" Jiang Yanhai gave two people a military salute, including this kid.
Qiu Xiaofei did the same.
"Uncle, can I be in the People's Liberation Army like you in the future?" Qiu Wenze raised his head and asked Jiang Yanhai.
"As long as you study hard, you can!" Jiang Yanhai nodded seriously.
"Uncle, I get it! I'll take the first place in the exam next time!" Qiu Wenze nodded his head and said.
"Come on, we all believe in you."
After coming out of the office, he thanked the teachers and the dean, Jiang Yanhai and the others left.
"... Chief, thank you." When he got out of the car, Qiu Xiaofei said seriously.
"Work hard, I hope you can come back to see them in an upright manner in the future, instead of us following you and monitoring you." Jiang Yanhai said calmly.
"Yes!"
"The hound arranged for someone to send him back."
"Yes!"
...
The matter of the information force has come to an end. Jiang Yanhai does not need to keep an eye on the rest of the matter. After getting on the right track, Hei Ying and Bei Chenxiang cooperate with Fan Tianlei and other management officers from the past, and the information force has already entered. On track.
And Jiang Yanhai's vacation was officially over. He still returned to the National Defense University for the time being. It was time for class. Mr. Liu hadn't informed Jiang Yanhai about the Phantom's drawings.
However, the shape and structure of the Phantom has already begun to blow in the wind tunnel. The shape of an excellent fighter must have undergone multiple considerations. The shape of any practical fighter cannot be said to be 100% perfect, but it can only be said that all its achievable performance , and then comprehensively consider the optimal choice.
There will definitely be trade-offs.
No design can be said to be 100% perfect, including the Phantom.
And the structural design is also related to your material. There are some structures. When the material cannot reach, even if this structure is used to make the fighter have super mobility, etc., but if you use it, it will directly Lead to disintegration, such a structure was naturally unreasonable at the time.
But if one day, there is a material that can achieve the strength to allow your fighter to adopt this design structure, then it will be perfect.
What you use mainly depends on what cards you have in your hand, but the preliminary results of the Phantom's wind tunnel have come out. This shape is already perfect, and it is somewhat similar to the J20, but overall, the rear wing is more bigger.
And it is also slightly larger than the J20.
Instead, I called Professor Zhao to confirm the engine. The Phantom engine has already started multiple test runs at the same time.
A total of 10 engines have been manufactured. Except for two of these 10 engines as spares, the other 8 engines have been tested in three different research institutes.
But so far, as the first built engine, it has been through 150 hours of long-term start-up test, and there is still no problem. Its overall structure, including wearing parts and load-bearing parts, is currently perfect condition.
Although this has something to do with the fact that this engine is not installed on a fighter jet, even if it is the case, in terms of its service life, this is currently the absolute number one in China!
Regarding this matter, Jiang Yanhai, who has returned to the National Defense University, began to demonstrate with Professor Qian and the others. To be honest, when Jiang Yanhai was studying the design concept of this engine, these design plans included a description of its stability.
But he never thought that this stability was so powerful!
In particular, another test result that destroyed the test drive made all the professors feel some shock.
For example, in the previous version of J10S Qinglong, all J10 engines cannot perform supersonic cruise, and the standard of supersonic cruise refers to maintaining supersonic flight for more than half an hour in the state of intermediate thrust.
These versions of the J10C engine can be turned on afterburner to enter supersonic speed, and the maximum speed can reach Mach 2.5, but in the afterburner state, the J10C engine cannot last for 10 minutes at full afterburner output, and 10 minutes is the limit.
In normal operations, the short-range full afterburner state, at most five or six minutes, is already the limit.
Exceeding this time will be dangerous for the engine. From this aspect, you can realize the importance of engine life.
At present, when the Wraith's engine is undergoing a destructive test drive, its duration at full afterburner is a full 3 hours!
Calculated according to the maximum speed of the Phantom's afterburner, Mach 4, 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 let it fly for 3 hours with full afterburner.

PS: 7 more completed! Ask for a monthly pass! Touching the chrysanthemum in front, brothers work harder, I am very interested~~
