Rebirth: Fight For Life

   Chapter 513 Sending the proposition (open for subscription)

   On the launch pad of the Changxi Satellite Launch Center, above the white Candle Dragon rocket, is the sky just exposed.

  The morning star was still twinkling in the sky.

  Gu Song, Jian Yushu, Guo Yue, and He Anzhi are all quietly waiting for the scheduled launch time of the Candle Dragon Rocket.

   This time, I was no longer as nervous, anxious and looking forward to it as before.

  With the support of iterative thinking and sufficient funds, in fact, many links have been tested and improved several times.

  In their hearts, they are very confident.

   In He Anzhi's mind, he never imagined that the development of launch vehicles could be carried out in such a way and with efficiency.

   Just like it was hard for him to imagine before, why private companies like Flint Aerospace and SpaceX can make breakthroughs in the aerospace field so quickly.

   One is self-developed satellites plus participation in the improvement of recoverable rockets, and the other is to directly develop their own launch vehicles.

   The point is, both sides succeeded.

   Among them, the development speed of the candle dragon rocket, of course, how to schedule this system engineering methodology has played a role.

   But the most important thing is that the young man beside him quickly gave solutions to many key difficulties.

   When he was full of expectation and suggested to his superiors that he should try his best to absorb Flint Aerospace as an important partner of the Aerospace Science and Technology Group, the superiors were silent for a while, and then told him to digest and consolidate the existing achievements first.

  Under the constant questioning of He Anzhi, who felt very incomprehensible, his superiors told him that Gu Song would be involved in a more important top-secret project.

  He Anzhi had no choice but to leave the superior's office. He didn't know that the superior leaders knew that Gu Song was the top scientific advisor of this project because of the inseparable relationship between the aerospace system and the hypersonic gliding vehicle.

   So now, he can only wait for the candle dragon rocket to launch successfully. Then, he will devote himself to the comprehensive upgrade of the Shenjian series of rockets.

  Gu Song's heart is indeed peaceful.

   The first trial, conducted here last August, was just a preliminary demonstration just to be on the safe side.

   For this candle dragon rocket, he has actually devoted several months to it.

  From the engine, to the material, to the sensor, to the guidance system... So many things, their design details, have been simulated in the mind.

   As long as there is no problem with the installation, testing and launch command, measurement and control team, there will be no problem.

   And these things are one of the best things that the Chinese aerospace system has always done.

   So after the countdown ended, the candle dragon rocket started to lift off as scheduled.

   After a short period of more than two minutes, the first stage of the rocket separated.

   At this time, the rocket just flew to the vicinity of the Carmen line, and the follow-up orbital mission was handed over to the Changan Satellite Measurement and Control Center to command and dispatch, while the Chauncey Launch Command Center nervously began to monitor the recovery of the first-stage rocket.

   Unlike the last test, this time, the first-stage rocket fell from an altitude of nearly 100 kilometers, and then it must be able to complete the recovery.

   To achieve this goal, the first stage of the rocket should retain enough fuel, and the engine should be shut down in advance to separate from the rocket body.

   Then, after adjusting the attitude, re-ignite and try to stabilize on the recovery track.

  During this process, the engine will be ignited repeatedly to control the speed of the rocket's descent, as well as the trajectory and attitude of the rocket's descent.

In the    launch command center, everyone could only watch.

   Under the current technical conditions, it is basically impossible to remotely control the rocket.

   The difference is a thousand miles away. From the discovery of an abnormality here, to the solution through calculation, to the issuance of instructions, it has long been irreversible.

   Besides, during the high-speed flight of the rocket, the plasma generated by the high heat will seriously interfere with the reception and transmission of signals.

   Therefore, automatic control can only be achieved by relying on the navigation system installed on the rocket.

   Real-time perception of its own attitude and position, compare the orbit data in the system, and make corrections according to the pre-set automatic program.

   Now, the data on the big screen makes people in the hall feel a little incredible.

  Gu Song touched Guo Yue's shoulder with his shoulder and gave him a thumbs up.

   Guo Yue smiled speechlessly: "If you want me to praise you, just say it."

   Such an awesome performance is naturally because the navigation system on the rocket is powerful to a certain extent.

   In essence, what everyone is most worried about is that in the first half of the first-stage rocket recovery process, the orbit will deviate to no end.

   Now, in the second half of recycling, I am more and more confident.

   After all, the altitude is getting lower and lower, and the speed has also dropped.

   And the state of the engine is still stable enough and the fuel is sufficient.

   Now, Skyrim can see the blip of the first stage rocket again.

After the    was separated from the main body, the first-stage rocket was re-ignited at high altitude, and after a parabolic trajectory, the recovery trajectory was re-aligned to the Chauncey Satellite Launch Center.

The    reentry ignition lasted for more than 20 seconds, slowing the initial fall of the rocket at high altitude.

   Now, the first stage of the rocket starts its third ignition, which is the landing ignition.

   This ignition will last longer, reducing the rocket speed to the point where a soft landing can be achieved.

  From the big screen, everyone saw flames spraying from the tail of the first-stage rocket, and the speed of the rocket was getting slower and slower.

After the speed of    dropped to a certain level, the landing bracket was smoothly deployed.

   In the command hall, everyone waited with bated breath, as if this would prevent the rocket from being disturbed by the breath they exhaled.

   Then, the huge first-stage rocket stood firmly on the specially built recovery platform.

   He Anzhi was the most excited.

   He almost jumped to hug Gu Song.

  Fortunately, after he jumped up, he remembered Gu Song's identity a little embarrassedly, and put his hand away again, the whole person has the demeanor of the Asian dance king.

  The command hall was immersed in a sea of ​​cheers. Only the commander remained calm, and the command team prepared to check the status of the recovered first-stage rocket.

   Because according to the original plan, if the first-stage rocket is successfully recovered, the maintenance of this first-stage rocket must be started immediately.

   Then, complete the hoisting of the same type of booster rocket, second-stage rocket, third-stage rocket and communication satellite as soon as possible to try the next launch.

  Gu Song remembered the limits of Musk's play, and wanted to achieve the successful launch of the rocket within 24 hours, quickly maintain and refuel it after recovery, and successfully launch with the payload again.

  Think about it, what's the difference between this and a flight?

   This time, Candle Dragon Rocket is not prepared to play that limit.

The    first stage rocket will be pulled back to the workshop and carefully inspected. After confirming that the conditions for re-launch are met, it will be assembled with other rocket components and launched again at an opportunity.

   Don't worry, with the first successful experience, the second time should be more secure.

The    side was immersed in joy, and then there was good news from Chang'an side. The communication satellite was successfully launched into orbit.

   For launching satellites, whether the recovery of the first-stage rocket is successful or not does not affect whether the subsequent second-stage rocket can push the satellite into orbit.

   In this regard, Hua Guo’s experience is already very rich and stable.

   Jian Yushu can't wait to announce it.

   The first-generation Candle Dragon rocket, which Flint Aerospace participated in in-depth research and development, successfully launched the first communication satellite of the "Qunxing" program into orbit, and successfully achieved the recovery of the first-stage rocket.

   This will be a big news that will shock the world!

   Less than half a month ago, SpaceX's success seemed so insignificant in an instant!

  …

  Gu Song had a celebratory breakfast with them and set off for the north of Sichuan.

   On this trip, there is another task, which is to take the old man Xie Hongxin back to Yanjing.

   It’s almost New Year’s Day in a month, and the project he is in charge of is nearing completion.

  Before the winter vacation, there will be some small constructions. But he and Nie Ziqiang have been training the team for so long, and there are people under him who can help him keep an eye on them, and there is no need for him to stay here until the end.

   woke up too early, he slept all the way.

  The car arrived at the county seat of Chuanbei and drove directly to the entrance of the newly built Chuanbei Middle School.

  The school is very conspicuous in this ordinary small county.

  From the design style to the construction effect, it is quite eye-catching. Gu Song believes that the build quality is also fully in line with the design standards.

   called Xie Hongxin, Zhao Hongtao parked the car, and walked to the engineering headquarters with the boss.

  Xie Hongxin stood at the door of the headquarters, watching Gu Song approaching strangely.

  Gu Song laughed shyly, his father-in-law was different from his mother-in-law. The mother-in-law was worried before, she was worried that Gu Song was just playing, and worried about the trouble in the future.

   But once the relationship is determined, it is natural to like it more and more.

   But the old man is different. After all, he is the jewel in the palm of his hand, and he was overwhelmed by this kid.

   But he also admires and likes this kid. To a certain extent, he is still Party A.

   What is this called?

  Gu Song said with a smile: "Uncle, why are you still outside the house? Hurry in, it's cold outside."

  Xie Hongxin took him and Zhao Hongtao into the door, greeted the people below to bring hot tea, and then said: "Go to check and check after the official business first?"

   Gu Song's scalp was numb when he heard it: "Uncle, you're staring at it yourself, it's definitely fine. Let's just...let's talk about private matters directly."

   Zhao Hongtao pursed his lips when he heard it interesting.

   After the two of them took a cup of hot tea and drank it, Xie Hongxin sighed: "When did you have such a bad idea?"

  Gu Song sweats profusely, what is bad thinking? But I can't say that I liked her since I was a child, right? That's outrageous.

   "It's just...it's natural to think she's good. After all, you taught her!"

  Xie Hongxin rolled his eyes and said, "Stop flattering. What do you do now? I don't think you can make a score in front of you! There's no way to deal with this in the future, it's embarrassing!"

   "What's so difficult about this... You are an elder, you can do whatever you want!"

"real?"

  Gu Song nodded continuously.

   "Let's go, don't drink the tea, anyway, it's almost noon, let's have a drink and talk about it!"

  Gu Song put down the teacup: "You are cooked here, where is it delicious?"

  Xie Hongxin waved his hand: "Follow me, I have the wine ready. Today, I have to let you drink well, I have to listen to your mantra!"

  Gu Song is so sweet. Anyway, he has the artificial intelligence "Xie Xiaobao" in his mind to suppress his emotions.

When    arrived at the place, Xie Hongxin said a lot, but he didn't really want him to drink.

   On the other hand, Gu Song himself respected his wine very seriously.

  Xie Hongxin sighed and asked, "Yin Ran is still young, what are your plans?"

Gu Song put down the wine glass for him, and said, "I am single-minded with Yinran, but now she is really still young and has to read. We have just expressed our hearts to each other, and Yinran also needs to get to know her in another capacity. Me. So, we can't just talk about marriage right now. You and my aunt believe me, just wait for her to finish college. At that time, I will marry her back home. "

  Xie Hongxin glared at him: "You also said that you don't want to talk about marriage directly, you just want to marry and go home."

  Gu Song gritted his teeth and didn't know how to answer.

Xie Hongxin took a bite of the dish and suppressed the smell of alcohol, then sighed: "I also talked a lot with her mother on the phone, and they were very contradictory. Xiaosong, I have known you for so many years, and Aunt Wang and I can trust you. But After all, you are famous now, your family has a big business, and your identity is precious, we are all worried that Yin Ran will follow you in the future, and there will be a lot of right and wrong."

Gu Song lowered his head and said, "I also talked to my aunt about this issue. Before that day has passed, I'm just talking empty-handed. No matter how well I say it, you are still worried. But then again, even if it's not me now. You and Auntie will be more worried about her being in love with Yinran, but she is in a relationship with some other kid, right? After all, you and Auntie still know the truth about me. "

"I just don't understand you more and more. I know where your roots are and what you are. But now it's a rocket and a robot. I understand a ghost?" He said here, looking left and right After taking a look, he lowered his head and asked in a low voice, "I heard your aunt say, you... have entered the sea?"

  Gu Song nodded and replied in a low voice, "I'm participating in two top-secret projects."

Xie Hongxin raised his head, looked at him dumbfounded, and then said helplessly: "Look, I don't dare to drink too much wine with you. If you are drunk and say things you shouldn't say, I should not listen to you. What else is there to do? In the future, this old man will not be able to find the taste!"

  Gu Song laughed and laughed, this is really a trouble that can't be helped.

   He could only continue pouring wine with a smile: "There are more good places than awkward places!"

  Xie Hongxin looked at him with his glass of wine in his hand: "Then let's talk openly between men and men. You said to wait for Yinran to finish college, then you can't bear to not touch her for four years? I don't believe it!"

  Gu Song was so embarrassed, why didn't he see him so bright before reading the file.

   But this is really hard to answer.

   I have endured this for so many years, and I am full of enthusiasm and do not know how many forest products are fertile. Now that both of them are in love, they are both adult men and women. If you want to endure it for another four years, it would be better to explode in place!

  Xie Hongxin saw his ghostly appearance and drank the wine with gritted teeth.

  Gu Song concealed his embarrassment by drinking, and saw Xie Hongxin eating food in silence, as if he was determined to wait for him to answer.

  Gu Song urgently organized language in his mind.

  Uncle, I won't force Yinran's... er, there is a high probability that the old man will be furious: Damn you, do you still want to force a relationship?

  Uncle, I will be responsible for Yin Ran... What if he gets stuck and comes back: I will be responsible for her and wait until the wedding room.

Uncle   , since it's an open talk among men, then you understand... Could it be that my father-in-law can only reluctantly say: We must take safety measures? Still studying, what should I do with a big belly?

  Gu Song felt that this open topic between men was a proposition!

   Continue 4000+ chapters. Thank you for how much youth you have left and Ye Yusheng Fan 6816 for your reward! Some things happened at home in the past two days, and I just sorted out the plot details of the new volume, and guaranteed 4000+ per day.
