932 Synchronous deceleration

July 27, 2029, Callisto Zero Advance Base.

The sky outside the base had just darkened, and there was still a trace of dark glow left on the horizon, and a construction truck was speeding all the way into the base.

Luo Qi hurriedly jumped off the engineering vehicle, washed his whole body as quickly as possible, and broke into the base command room in a hurry: "Boss, has it started?" ”

Ye Han smiled: "It's okay, just in time, sit down." ”

Today is the day when the rail elevator cable arrives at Europa, in order to ensure the smooth progress of the project, the northern capital requires the forward base to go all out, and there must be no problems.

Ye Han almost didn't worry about his gray hair after receiving the order, there are so few people in the entire advance base, and more than half of them are engaged in research, there are only two groups of people who can be used in his hands, and there is also a group of people who are resident in the center of the earth, how bad do you think, Xin Yiheng simply called Luo Qi back to help.

Luo Qi sat next to Ye Han and glanced at the transport ship with its tail on the main screen: "Where is this?" ”

The picture on the main screen comes from the Tianhe and several other spaceships, not only from the front, but also from the side, and in both directions.

Ye Han glanced at the time, and before he could speak, Ouyang Ping had already taken the lead: "The horse is here." ”

As soon as the words fell, a voice came from the speaker: "Base, arrive at the predetermined coordinates quickly, please instruct." ”

Ye Hanma put his mouth in front of the microphone: "The base received, fast nine keep the speed, fast three, report the location!" ”

Fast three and nine are the abbreviations of fast transport ships, and the name of this thing is quite simple, but every time he calls a transport ship, Ye Han thinks of ballroom dancing.

"Hurry up and report, our ship is already in place, ready to capture the cable tail!"

The screen changed to the very end of the cable, and due to the angle of the shot, the image of the transport ship approaching the cable looked like looking up and watching the remote-controlled aircraft fly towards the flagpole.

Ye Han instructed in a low voice: "Hurry up, pay attention to your posture, and grasp the timing by yourself!" ”

"Hurry up and understand!"

Ye Han frowned and didn't speak, the radio fell silent, and several people stared at the transport ship that was constantly approaching the cable.

Luo Qi broke the silence: "Boss, this is no problem, right?" ”

Ye Han shook his head: "It should be no problem, the new captain of Kuaisan is very experienced, and his head was specially transferred." ”

Luo Qi blinked suspiciously: "What kind of experience?" "The fast transport ship has only been out for a few months, and he can't think of any anti-sky skills that the most experienced captain has.

Ye Han glanced at Luo Qi: "Docking experience, when building the orbital factory and the space city, he was specifically responsible for docking. ”

"Oh, cowman!" Luo Qiden admired it very much.

Space docking has always been a technical job, but the docking difficulty of the two ground-to-air spacecraft can only be regarded as average, as long as they are systematically trained.

Replaced by two low-tonnage light space warships, the difficulty directly jumps a step; If it is replaced by a heavy space battleship, the docking difficulty must increase in geometric progression, direction, angle, speed, position, and attitude, as long as one thing goes wrong, it is not a small trouble, and the docking will fail at least and the spacecraft will be damaged.

The docking difficulty between the orbital factory and the space city is still higher for heavy warships, and if the shape of the docking parts is more complicated, the difficulty will be one level higher.

Such a big bull is a strategic-level existence wherever he stays, which shows that Beidu attaches great importance to rail elevators.

Several people waited patiently for a while, and the three ships finally approached the tail end of the cable, and an indifferent voice came from the radio: "The azimuth difference is four, the angle difference is two, and the left rudder is two!" ”

"Left Rudder Two...... Left car into two! ”

"The second engine on the right, the power is 5 and the output is one second......"

A series of steering commands came out of the speaker, and the fast three ships on the main screen kept adjusting the position of the hull, gradually coinciding with the tail end of the cable, and several mechanical arms poked out from under the belly of the ship, slowly and steadily grasping the reserved cable hole at the tail end of the cable.

A particularly pronounced exhalation came from the speaker: "Alright, horse fixed!" ”

Ye Han also breathed a sigh of relief: "It's finally good." ”

"Is this over?" Ouyang Ping sighed for a while, "It's really worthy of being a big bull." ”

The length of the cable towing is more than 24,700 kilometers, and the relationship between the Kuaijiu and the cable is like a whip handle and a whip tip, and an imperceptible vibration of the Kuaijiu can become a large swing of the cable tail after being magnified for more than 24,000 kilometers.

Approaching the end of the cable is only the first step in catching the tail of the cable, and the next step must be to catch the tail of the cable before the end of the cable changes.

The screen switched to the belly of the fast three ships, and I saw several mechanical arms pulling the collar of the tail of the rope and pulling the collar towards the belly of the ship...... The collar is a metal ring specially added to both ends of the cable in order to fix the cable.

Through the lens, you can see that the cable is surging rapidly with a raised crest, and if the movements of the fast three ships are a little slower, the tail of the cable must change direction because of this crest.

The mechanical arm quickly pulled the tail into the belly of the ship, pressed the fixture inside the ship, and the open hatch slowly closed, firmly fixing the tail and the fast three ships together.

As soon as the hatch was closed, the crest of the wave happened to be thrown at the tail of the rope, and the fast three ships suddenly changed direction without warning, drifting some distance in the direction of the swing.

Luo Qi's eyes almost didn't pop out: "Isn't it?" So much energy? ”

Ouyang Ping squinted his eyes and looked at Luo Qi, as if he had never known him: "What are you talking about?" That's the fast three flew by themselves! ”

Luo Qi was stunned: "What's wrong with being afraid of tearing it up?" ”

"Then I don't know." Ouyang Ping said.

Luo Qi looked at Ye Han, and at this time, the speaker rang: "Base, hurry up and prepare to slow down." ”

"The base received, Kuaisan, you and Kuaijiu coordinate by themselves."

"Kuaisan understands...... Three calls nine! ”

"Hurry up and get it!"

"Our ship is ready to slow down, you guys hold steady!"

"Kuaijiu understands!"

"Slow down the countdown, three, two, one, start!"

As you can see from the screen, the engine of the fast three ships exploded a few flashes, but the horse was annihilated.

At the same time, the Kuai-9 ships at the other end of the cable also slowed down and cooperated with the command of the Kuai-3 ships, and the two transport ships were more than 24,000 kilometers apart, but they always kept their speed synchronized.

With the strength of the cable, it is no problem if the fast nine ships do not slow down, but in that case, the entire deceleration process will inevitably depend on the fast three ships, not only will the deceleration take longer, but the cable will also be tightened by the two spaceships.

More than 24,000 kilometers of cables, the elasticity together is not a joke, in case of a rebound, maybe there will be some chaos.

Again, the construction close to Europa requires the cable to be relaxed, not dragged by a tug-of-war between two spacecraft.

Therefore, the two ships must slow down synchronously to avoid omissions as much as possible.
