Chapter 1434: Slingshot effect!

The latest website: The communication module has been physically removed. It seems that the hijackers had no intention of dialogue from the beginning. The complete dismantling of the real special lady, even the backup communication system, was unplugged. There's also a remote control module and an autonomous driving system ... Damn it! "
Squatting in front of the console was a low-profile man with glasses.
His name is Fan Sheng, and he is an engineer in a pan-Asian space company.
About a week ago, he went to Tiangong City to attend an academic lecture, but he did not expect to encounter such a thing on his way home.
However, it is also because of his presence here, otherwise the bionic person that Xiao Ai sent to pick him up has been scrapped in the previous battle, and Lu Zhou really doesn't know what to do.
Looking at Fan Sheng sweating, Lu Zhou asked with a frown.
"Can you fix it?"
"It's impossible to fix it. In this way of violent dismantling, they never even thought about putting these gadgets on," Fan Sheng's face appeared a bitter smile, raising his arm and wiping the sweat on his forehead "But fortunately, fortunately, their understanding of this transport ship is still not in place. I changed the setting of the sending device on the facility maintenance system and switched to the developer mode. Although the channel is narrower, but if it is only audio Calling should still be possible. "
Lu Zhou immediately said, "Can it be used now?"
"It's okay ... I received a strange communication request here. It should be that the Pan Asian Fleet side noticed the anomaly on our side."
Lu Zhou: "Connect them immediately!"
Fan Sheng nodded quickly, and ten fingers quickly tapped on the holographic panel.
"Okay ... get it!"
The light and shadow on the holographic panel changed, and a video call window was quickly presented in front of Lu Zhou and Fan Sheng.
Although the position of the video window is white, and the person standing at the other end of the video cannot be seen, the repeated sounds coming from there can be clearly heard.
"... Here is Pan-Asian First Fleet, Flight N-177. Can you hear me?"
"If we can hear it, we hope to start a dialogue with you. No matter what you ask, the door to dialogue and peace will always open ..."
Taking a deep breath, Lu Zhou said.
"Here is Flight N-177 ... I am a passenger on the flight, and we have regained control of the flight from the hijackers."
The opposite side remained silent for a while, seeming to be surprised by the news.
Lu Zhou waited quietly for two seconds, and a response sound came quickly from the other end of the communication channel.
Pilot: "Can you slow down?"
"Yes ... we have shut down the main engine, but the auto-navigation module has been removed by the hijacker and the two captains have also been executed by the hijacker," Lu Zhou said with a headache, looking at the channel data displayed on the navigator "You better send someone to help us ... those hijackers can board this transport ship, should you have a solution?"
This time the communication channel was silent for a long time.
Pilot: "... N-177, when you hear this news, I hope you can stay calm."
From that heavy tone, Lu Zhou had vaguely guessed something, and he couldn't help but sink into the valley.
Taking a look at Fan Sheng next to him, he said for a moment, silent.
"You say it."
Navigator: "You have missed the final deceleration window period 37 minutes ago."
Lu Zhou: "That means we can't come back?"
Pilot: "Yes ..."
Lu Zhou did not answer immediately, but glanced at Fan Sheng next to him.
"Is that so?"
Fan Sheng's face was pale, his lips nodded tremblingly.
"... There is such a saying. But not so much? It should be rescued! What about your landing craft? At least send us some supplies ..."
"The Dolphin 230 transport ship has 12 pairs of K-15 electric main engines. Even if the Pan-Asian Fleet ’s Sentinel-class patrol ship buys working loads from the nearest space port, it is difficult to accelerate Reach the same speed as you in 72 hours. The rescue window period is only 11 hours. Once you pass the Earth-Moon system, it will take up to two weeks at the earliest for our aircraft carrier to be away from your flight. The docking is completed on 37 million kilometers of orbit per month. "
Lu Zhou looked at Fan Sheng and continued to ask, "Is this true?"
Fan Sheng nodded pale.
"At the beginning of the design of the Dolphin-type civil transport ship was to facilitate passengers to quickly travel between the Earth-Moon system and the Mars system. Therefore, 12 main engines were installed at the rear ... It ’s true that the military transport ship may not catch up. "
"Those air thieves have been preparing to ambush us, I've probably been preparing for a week ..."
While Fan Sheng was explaining the reason to Lu Zhou, looking at a snow-white video window in the headquarters of the Pan Asia First Fleet, Yang Wu stepped forward and patted the pilot's shoulder.
"Let me talk to them."
The pilot glanced at the commander and saw the latter nodded, so he gave up his place.
The replacement pilot sat in front of the console, and Yang Wu stared at the snow-white holographic video window with a serious and calm voice.
"Here is the Pan-Asian First Fleet Command. I am Yang Wu, a consultant for military operations."
"Although I'm sorry to inform you of this news, the chances of your returning safely are very small. Even in the best condition, it will take two weeks for our rescue workers to arrive. So we need you to take some necessary self-rescue measures to Avoid the worst. "
"... If you can control this flight, I hope you can turn on the left-steering engine, change the current course, and avoid directly colliding with the Tianzhou space station."
Lu Zhou: "How many degrees do you turn to the left?"
Yang Wu: "If you are not sure, keep the left-steering engine running at full power for more than 720 seconds."
720 seconds ...
Full power turns for 720 seconds, which is equivalent to avoiding the earth directly and plunging into the unmanned deep space.
Lu Zhou: "Do you mean let us give up?"
Yang Wu said in a serious tone: "We have never given up on you, and absolutely have no intention of letting you give up. Just for the safety of the tens of thousands of residents on the spacecraft Tiantian and the space station, I hope you can maintain a sufficient safe distance from it. We will Do your best to rescue you, but I also hope that you think about the big picture. "
"What do you call it?"
"Yang Wu."
"Comrade Yang Wu," staring at a white snowflake in the holographic window, Lu Zhou's tone gradually subsided. "There are more than 200 passengers on board, most of them are my compatriots, and there are others from all over the world. The people of the country and the organization. I agree with your big picture, but things are far from that. As long as I'm here and I'm alive, I won't allow them to die for nothing. "
Yang Wu: "Will you fly a transport ship? What do you want to do?"
Lu Zhou smiled slightly.
"The principles are actually the same, the difference is that the operation has become more cumbersome. The essence of aerospace is a mathematical problem, and as long as it is a mathematical problem, there is a solution."
Yang Wu narrowed his eyes and stared at a snowflake-white holographic screen, Shen Sheng said.
"who are you?"
"It doesn't matter who I am, I just need your side to cooperate with me."
Communication was interrupted.
Flight N-177 seemed determined to take a bet on the fate of itself and the Tianzhou, and went on its way along the established course.
At the command room of the Pan-Asian First Fleet, at this moment it was surrounded by tension.
Everyone's nerves were stretched to the limit, staring at the blinking green dot on the radar.
"The channel has not changed. Flight N-177 is heading for Tianzhou!"
"Expected collision in 11 hours!"
"Aim at them, we can't let the tens of thousands of residents of Tianzhou take the risk!"
"They have no chance of surviving ... if anything, even 1%-"
"It's not completely absent," looking at the adviser's team of consultants, the aerospace technology consultant who has not spoken, and suddenly said, "Although the possibility is probably less than 1% ..."
The commander immediately looked at him: "What do you say?"
"The slingshot effect," looking at the commander, the aerospace technical consultant continued, "Although according to the current channel, their remaining fuel can no longer be returned by normal means, but it may not be possible if the slingshot effect is used."
The army adviser frowned and asked.
"Slingshot effect? ​​I remember that wasn't used to accelerate the unmanned detector?"
"It is not necessarily acceleration. When the planet moves to the right on the horizontal plane, if the aircraft flies the planet from the left side of the planet at an appropriate angle, it will receive a rightward impulse from the planet. In theory, if they are synchronized from If you fly around the earth in orbit, you can use the slingshot effect to extend the rescue window period as long as the cut-in angle is appropriate. "
Commander: "How long can it be extended?"
"I said badly, shouldn't such a thing be asked about a computer?"
The commander immediately looked at the staff at the control desk and ordered.
"To launch the AI ​​battlefield analysis system, I need to know the success rate of the plan and the possible risks."
The progress bar on the holographic screen flickers slightly.
Soon, the results of the assessment appeared to everyone.
And this result, the expressions on everyone's face are frozen.
"The success rate is 2% ... the probability of collision of the spacecraft in synchronous flight with the Tianzhou space station is 75% ... Damn, this is assuming there are experienced pilots on flight N-177!"
"Too difficult! Too many variables are difficult to control! To put it bluntly, the slingshot effect simply cannot accurately control the speed and direction of operation. Even experienced drivers will not regard it as a routine Means of acceleration and deceleration! "
"It's just a joke!"
"They are crazy!"
The commander's face was expressionless, his fists clenched tightly, as if struggling.
Standing next, Yang Wu glanced at him silently, but just asked.
"does it worth?"
People in a city take risks for people in a boat.
Is it really worth it?
...
To be honest, Lu Zhou didn't spend much time thinking about whether it was worth it.
As a scholar, he only considers one problem, and that is the optimal solution in the current situation.
Accurately parameterized vertical stacked blocks, no matter which parameter is adjusted, a little carelessness may lead to extremely serious navigational accidents.
Not surprisingly, they will fly over geosynchronous orbit in 11 hours and have a great possibility of colliding with the spacecraft Tianzhou.
To be honest, the window period is very short, not to mention the most complicated manual driving.
His calculations must be accurate, not even a small error.
If he wants to survive, he must make good use of every reserve of working fluid, ignite the lateral engine at critical moments, and use the slingshot effect to complete the final deceleration.
Standing next to Lu Zhou, the engineer named Fan Sheng suddenly said in despair.
"I bet we must have been targeted."
"aim?"
"We are now like a missile, crashing straight into the Tianzhou," Fan Sheng's face was full of bitter expressions, "it must be like this in their eyes, the orbital defense weapon will definitely respond. If I were them , It certainly won't allow this to happen. "
"I do not rule out this possibility, but I believe it will never happen." Looking at Fan Sheng, Lu Zhou was silent for a while, and stretched out his hand and patted his shoulder, "Go to the cabin and rest for a while, I want to be alone Stay for a while. "
Fan Sheng: "Can you tell me, what are you going to do?"
Lu Zhou: "Slingshot effect."
Fan Sheng opened his mouth, and after a while, he squeezed a word out of his throat.
"It's crazy ..."
After leaving the cockpit, Fan Sheng returned to the cabin, struggling to make his expression not too heavy, and walked back to his position in silence.
Professor Leonard sighed and looked sadly at the starry sky outside the cockpit. "Are we already dead? Can anyone give me an idea?"
Fan Sheng: "... not so desperate, but not much better."
The eleven-hour wait was so long.
The sights of the world are being drawn to the flight that has come out of the deep sky and is out of control.
The inhabitants of the orbit, who were too late to evacuate, spontaneously came to the floor-to-ceiling window, praying for the spaceship that was getting closer, and praying for their own destiny.
In their pupils, they saw only a dark shadow getting closer and closer, blocking their view of the moon.
At this time, a miracle happened.
Even with infinite proximity in astronomical distance, the huge hull eventually did not hit, but passed by with the Tianzhou.
The land boat sitting in the cockpit slowly breathed a sigh of relief, and the whole person sat down in the driver's seat.
In the cabin, the tense Professor Leonard stared at the towering fortress outside the window.
On this astronomical voyage, he could even clearly see the orbital residents outside the window who stood in front of the floor-to-ceiling windows overlooking them.
Opposite, saw him and them the same.
This is probably the greatest moment in human history.
At least, it's one!
A man from 100 years ago saved a runaway flight and everyone on the flight.
And even at the last minute, people have not given up hope and chose to believe in each other.
"In our day, it was usually the worst, even if I was not a pessimist ..."
Taking off the hat above his head and putting it in his arms, Yang Wu looked at the commander and solemnly said, "It is your courage to save the two hundred passengers."
"We also plan for the worst, Comrade Yang from 2050 ..." Taking a deep breath of cold air, the commander's tight shoulders finally relaxed, and he responded with a slightly relaxed smile. "Just by comparison, so many people still believe in us."
"I don't want to let them down, even for the sake of those who trust us."
This disaster will strengthen the people of Pan Asia.
Although, similar things, he did not want to have a second time ...
On flight N-177.
Cheers and cheers sounded again.
The spacecraft passing by from synchronous orbits slowly sails from the back of the earth toward the sun.
Just as overlooking the sunrise, the brilliance of the morning light lit up the blue horizon. Under the dazzling light, the planet was so beautiful.
The child who was standing in front of the window ~ EbookFREE.me ~ looked at the shocking scene outside the window, his little hands squinted tightly, as if he had caught the dream.
He didn't know he had just experienced the most dangerous moment in his life.
All he knew was that he, who was born and raised on Mars, saw the most spectacular sunrise in his life at this moment.
Looking back in excitement, he looked at his mother.
"Mom, is that the earth?"
The childish milk sound is full of yearning for beautiful things.
The mother sitting next to him smiled softly.
"Yes."
"There is where the mother was born ..."
