Chapter Fifty-Six: Raising Your Head Requires Confidence
A media conference room is half researchers, half administrative. Sitting around the long conference table, his eyes were fixed on the person sitting in the first place, looking attentive.
"Let me emphasize to you again, this mission, it may not be possible," he said, poking the cigarette butt in his hand into the ashtray, staring at everyone, gritting his teeth.
"Okay, you have to do it, you can't do it, you have to do it, 15 days, isn't it just to change the drawings? Won't the kung fu of adding two classes come out? ”
Among the executives in shirts and suits, a few nodded nonchalantly, laymen, who knows what these 15 days mean.
On the other hand, the team of engineers in gray research coats were almost all sad, and for them, this request was tantamount to asking them to plant an apple core and grow into a tree in 15 days.
It's hard to climb.
"Director Wang, can you do this job well, you can make a statement for us." The man sitting at the top looked at a room of employees who were silent and were a little unhappy with the quiet atmosphere.
When an engineer sitting on his left heard this, he straightened up and pinched the manuscript in front of him, "Minister Li, this... ”。 How does this state be expressed? How can he speak?
"Say, what are you doing?" The pot-bellied leader looked dissatisfied.
Say? How so? This kind of impossible task, is to pat your chest and guarantee it, what's the point, it's better to push this trouble to others, thinking, and glanced at a few people on the side.
"Minister Li, you see, we just received this job, and before we discussed the plan, we were called over for a meeting, what is the mentality of the team members, I don't have a number, otherwise let's let everyone talk about it, and we can find out the bottom of it." Director Wang pushed the ball onto the entire team and jumped out of the Three Realms by himself.
Minister Li glanced at the team of engineers, and looked at the people who were almost under the table, and his eyes were a little unkind.
"Su Province" he pointed to the only young man in it who was staring ahead, as if pondering the problem. "You're in orbit design, tell us what you think."
At this moment, Su Province is still pondering the orbit change plan of Asia No. 3, calculating the energy consumption ratio when accelerating at perigee, he has not closed his eyes for two days and one night, and his mind is already a mess, and he is interrupted by the leader like this, and it is easy to have some eyebrows in his thoughts.
"Minister Li, the way to change the engine doesn't work logically" Su Province said the answer that everyone knew very well, and many people were relieved when they heard this. I thought to myself, this stunned young man is really not afraid of death.
"Why doesn't it work?" Minister Li locked on him with his eyes, and his body was like a cat about to explode.
"The companion satellite of Chang'e-5 is a transit communication satellite in its own design, and the maximum load of the in-orbit time and the number of orbit changes can only support it to persist until the return of the 5th, and there is no problem in replacing the long-optical communication module, which can be completed in 5 days instead of 15 days. However, the engine expansion could not be done, and the fuel distribution scheme could not be optimized, unless the fuel tank was added.
However, with the addition of fuel tanks, it is necessary to redo the center of gravity, centroid mapping and digital orbit change deduction, and it will not take a month to get out. ”
"Did I ask you this?" The minister's voice became low and aggressive, and the atmosphere became solemn.
People who stay up all night have a strong liver fire and are easy to get angry, Su Xing listened to these obviously pressured words, and forcibly held back the anger in his heart.
"I'm asking you if you can get this orbital endurance for me in fifteen days?" The voice was raised in vain, as if to show the crowd the consequences of disobeying him.
When he shouted, Su Xing woke up, and recalled the post he saw on the Internet a few days ago seeking a partner, and the nameless anger that had been suppressed for a long time rushed up, and he looked at the long heads in front of him purely to look tall, except for intrigue, it seems that they have never seen them invest in research and development.
"Isn't it just a lunar satellite? If you really want to rush it, I'll give you a solution. As soon as the words came out, the whole conference room could be heard falling needles, and under the flat tone, it seemed that a fierce beast was dormant.
"Is this your attitude towards talking to the leader?" Director Wang, who was sitting on the side, helped, he looked at Minister Li's red and purple face, and quickly unscrewed the mineral water on the table and pushed it over, "Minister, you dissipate your gas, dissipate your gas."
Seeing Minister Li's appearance, Su Xing's heart was relieved, the shackles of returning to China for three years seemed to have disappeared without a trace at this moment, and the unbridled nature that originally belonged to him once again returned to him.
"Look!" As he spoke, he took out a few drawings that had been printed out in his hand, held them up and showed them to everyone present, on which were impressively printed a communication satellite and several orbital diagrams.
"I don't know how much you know about this revision plan, I compared the Changguang communication satellite launched in October, and found that it is only higher than the requirements in our plan."
As he spoke, he pointed to the diagram with many circular lines:
This is the "Asia III" communications satellite launched at the Baikonur Space Center on December 24, 1997, due to the failure of the fourth stage engine at that time, the satellite was stranded in a geosynchronous transfer orbit with an inclination of 51.2 degrees, of course, the insurance company defined the failure as a "total loss" and paid Hughes $200 million in compensation. ”
Su Xing looked at the wide eyes in the conference room, and knew that they hadn't connected these three things yet, and couldn't help but shake his head and smile.
"Do you know about Hoffman's orbit change technology and Belbruno's ballistics?" The mocking look stared at the leaders around the minister, without the slightest look of fear.
"On April 10, 1998, the Asia-3 satellite used these two orbital algorithms to ignite and go straight to the moon, and then the Asia-3 satellite continued to ignite for a short time to gradually reduce the orbital inclination.
By May 7, 1998, the Asia-3 satellite had carried out a total of 11 perigee ignitions, and the semi-major axis of the orbit was raised from 24,549 kilometers on April 10 to 166942 kilometers.
At that time, commercial vehicles designed and produced by humans had never reached such heights, which went far beyond geosynchronous orbit. Since then, each step of the Asia-3 satellite has set a new record. ”
Su Xing held up the drawings in his hand, like a speech, and burst out the anger that had been suppressed in his heart for three years.
"On May 7, 1998, the satellite ended its current large elliptical orbit around the Earth and began to go straight to the moon! After the first rendezvous with the Moon, the inclination decreases further due to gravity.
Then, after a second flight around the moon, the orbital inclination was reduced by another 4 degrees. Houston then made further orbit adjustments using satellite engines.
In this way, the satellite entered a geosynchronous orbit with an inclination of only a few degrees, and the rescue operation was successful. ”
Su Xingxing left his seat, walked behind Director Wang, and threw the photo of the Changguang communications satellite launched in October on the table of him and Minister Li.
"That's my way,"
"In addition," Su Xing said slowly, he felt that he was no longer angry, and instead glanced at Minister Li with an almost pitying look,
"I resign."
