Chapter 859
"Mr. Lin, our Lingxiao space station is only at this height.
At a height of 400 meters, it is enough to carry out the main tasks of human space exploration."Hua Xing couldn't help but speak.
He was really nervous.
Breaking through 400 kilometers is already very impressive.
Going up further, the environmental conditions are very harsh. If there is a problem with the plane, the gain will outweigh the loss.
"It's okay, it needs to have the ability to explore the moon at least for now, and it must enter the outer atmosphere."
Lin Feng shook his head, unmoved.
The outer atmosphere is the escape layer, also called the exosphere.
The place where the high-speed moving atmospheric molecules and atoms break away from the gravitational constraints of the earth and enter the universe. The atmosphere here is extremely thin, and the atmospheric molecules and atoms Like tiny missiles, the kinetic energy is extremely high.
Seeing Lin Feng’s insistence, Huaxing didn’t say anything more and looked at the data sent back again.
"At an altitude of 450 kilometers, it will enter the outer atmosphere.
The external temperature is 1660 degrees Celsius, the cabin temperature is 25 degrees Celsius, and the air pressure is 101.3KPa. The data is normal."
As the plane approached the outer atmosphere, everyone became more and more nervous.
The scene was dead silent for a while. Even Xiao Wushuang felt that the atmosphere was very strange and did not dare to speak anymore.
"At an altitude of 500 kilometers, it enters the outer atmosphere.
The external temperature is 2530 degrees Celsius, the cabin temperature is 25 degrees Celsius, and the temperature control system is normal.
The air pressure is 101.3KPa, the air pressure is normal, the environmental control and life support systems are normal; the power supply and distribution systems are normal; the measurement, control and communication systems are normal.
The propulsion system is normal; the robotic arm system is normal; the crew system is normal.
The instrumentation and lighting systems are normal; data management is normal."
The next moment, the screen in the command center showed the scene inside the aerospace aircraft cabin.
This scene made everyone in the command center clenched their fists heavily, with excited faces and applause.
It was a success, beyond compare. It went smoothly as imagined.
The test flight of the aerospace plane was successful, and the breath in my heart relaxed, and I felt extremely relaxed.
Seeing Mo Xinya and Jiang Feng coming over, Lin Feng also smiled.
In Jiang Feng's arms, there was that A clingy little girl.
Lin Feng and Mo Xinya were speechless sometimes.
This little girl was closer to Jiang Feng than anyone he had ever seen.
He didn’t even know if she was giving Jiang Feng a lollipop. Bought
"Dad, I want to fly on the big plane you built."When Xiao Wushuang saw Lin Feng, his eyes turned into crescents.
"You can't fly on the big plane now. It's gone to space. Dad will get a small plane for you to play with later."
Lin Feng touched Xiao Wushuang's head and took her from Jiang Feng's arms.
"Thank you Dad, but where is space?"
"Space is the sky, the very high sky"
"Is there a fairy sister in space?"
"There is no fairy sister in space, but when Wushuang grows up, Wushuang will be a little fairy in the sky."
Mo Xinya and Jiang Feng smiled helplessly when they saw these words from their fathers.
"Okay, Wushuang, let’s see the big plane next time. Dad has to work."
Mo Xinya looked at the experts and academicians who were trying to gather around, and motioned to Lin Feng to put down Xiao Wushuang.
She also knew that now was not the time to talk about family matters.
"Okay, dad go home early, mom and I are waiting for you at home.
Uncle Jiang remembered that he came back with his father tonight, and Aunt Xiong also kissed him."
The little girl was very sensible. She gave everyone a kiss and followed Mo Xinya away obediently.
Seeing Xiao Wushuang's jumping back, Lin Feng showed a soft smile.
"Is my daughter sensible?"
"That's my daughter."
Lin Feng laughed angrily at Jiang Feng. He wanted to snatch his daughter in front of his father in broad daylight.
"it's the same. Jiang
Feng smiled slightly and looked at the experts and academicians who came over:
"I may not be suitable to listen to what you say next. I will go and play with my daughter first. If anything happens, please inform me directly. After saying that
, Jiang Feng turned around and quickly caught up with Mo Xinya and Wushuang.
"congratulations"
"Congratulations, Academician Lin"
"……"
All the experts present came to congratulate him, with joy on their faces.
Rise withstood the harsh conditions of space and successfully reached the outer atmosphere.
This means that aerospace aircraft technology has matured, and China’s speed in exploring space will be at the forefront of all mankind in the future.
"Academician Lin, congratulations on the successful test flight of your aircraft. Are you interested in cooperating?"
After congratulating him, Zhang Jianfeng spoke with expectation in his expression.
"Moon landing?"Lin Feng asked
"Yes.
Zhang Jianfeng nodded:"Would you like to try it?" The data resources we have can be shared with you"
"Including lunar orbit data and data on the far side of the moon, as well as orbit data of the Lagrangian L2 point?"Lin Feng asked.
Lagrange points are five special solutions to the restricted three-body problem in celestial mechanics.
An object is under the gravitational influence of two large objects.
At a certain point in space, relative to the two A large object basically remains stationary.
In a system composed of two celestial bodies, according to the inference, there are five Langrangian points, but only two points are stable.
The mathematician Euler calculated the first three special solutions. Later, The Gallic mathematician Lagrangian derivation proved the remaining two special solutions.
The Lagrangian L2 point is located on the Earth-Sun connection, allowing satellites to stay for a long time.
It consumes very little fuel and is an important part of international deep space exploration. The hotspot location.
L2 point is also the only one of the five points located on the Langrangian point on the far side of the moon.
Before Chang'e-4 landed on the far side of the moon, the project team placed the Queqiao center in the orbit of the Lagrangian L2 point. Relay satellite.
It allowed the Chang'e that landed on the far side of the moon to successfully communicate with the earth.
People only saw Chang'e landing on the far side of the moon, but during the detection of the far side of the moon. The Queqiao relay satellite at L2 point was the real protagonist of that show..In deep space exploration, the back side of the moon always faces away from the earth.
It retains the most primitive environment and is not infected by the earth's electromagnetic waves. The exploration value is much greater than the front side of the moon.
Therefore, if Lin Feng lands on the moon, he will definitely choose the back side.
"Okay, all of this data is fine."Zhang Jianfeng readily agreed.
Data is always data. Lin Feng has the technology. It is not difficult to obtain data. It is just a matter of time.
And Lin Feng's technology is more important.
Under the premise of cooperation, data sharing is within the normal scope.
"I have plans to go to the moon in the future, and we can cooperate then. Lin Feng said with a smile.
With their data, he has a lot of work left.
Although he can get these things by spending time.
But what he lacks most now is time. If he can speed up, he will definitely not refuse.
"I hope we can have a pleasant cooperation then."
Zhang Jianfeng smiled broadly. When he saw Hua Xing coming over, he smiled and gave up his position to Hua Xing._Fei
