The northern space city invested and built locally by Homo sapiens Company has finally completed all construction projects and solved various technical problems of the Dandelion Mass Projector.
Even Li Qingye, who has been operating at the Southeast Asia headquarters, took the Fourth Aerospace Fleet from the headquarters to Motor Island a few days ago.
He has conducted a rough inspection of various industries and cities in the Motor Island Branch in the past few days.
At this time, he was visiting the entire base, accompanied by Su Changli, the chief engineer of the Dandelion Project.
Inside the space station in the underground base.
A space train is on display on the track.
"Mr. Chairman, this is the Huozhizhi space train we designed." Su Changli introduced him excitedly.
Li Qingye looked at the fire account with a special shape: "Is that the fire account inside?"
Su Changli nodded: "Yes, there is a vacuum track outside. I call this part the cartridge case."
The so-called cartridge case is that this thing itself is part of the vacuum electromagnetic acceleration pipeline. It is specially designed like this for the convenience of rapid launch.
The length of this section of the pipe is 300 meters, and the inner diameter is 30 meters. The Spark space train installed inside is 100 meters in length, and has a diameter of 10 meters.
"What is the payload of the Spark?"
"The take-off weight of Huozhong is 12,000 tons, the payload in low-Earth orbit is 4,000 tons, and the payload in geosynchronous orbit is 3,000 tons."
"The low-Earth orbit effectiveness coefficient is 33%? Not bad." Li Qingye was very satisfied with this data.
Although Su Changli was very happy, he did not get carried away: "In fact, this also requires electromagnetic acceleration and vacuum pipelines, otherwise it will be difficult to achieve."
Why are the effectiveness coefficients of conventional launch vehicles in low-Earth orbit below 3%?
The reason is that initial acceleration and air resistance consume a large part of the launch vehicle's power.
The mass projector of the Dandelion Project will increase the speed of the Spark to the first cosmic speed based on the electromagnetic acceleration in the ring pipeline stage, and then project it out.
After being projected out, the Spark will continue to fly 30 kilometers in the vacuum tube. During this period, the Spark's engine will start to continue to accelerate the Spark and offset the earth's gravity.
Li Qingye looked at it for a while: "You guys arrange the launch!"
"Okay." Su Changli quickly called Bai Sha, the head of another technical department, and asked him to arrange the launch work.
The huge shell-shaped pipe, carrying the Fire, passed through the track and slowly moved to the ring-shaped acceleration pipe, where there happened to be a gap.
After the two were combined, the staff in the control room started the vacuuming process.
The air inside the entire annular pipe and the column-type vacuum pipe pulled by the annular airship decreased rapidly.
The vacuum system does not stop operating until the air density in the vacuum pipe is equal to the air density at an altitude of 30,000 meters.
The reason for not completely vacuuming is that on the one hand it is impossible to completely vacuum, and on the other hand it is to avoid a sudden difference in air density.
Choosing to keep the density consistent with the air density at an altitude of 30,000 meters will prevent the Fire from being affected by the difference in air density the moment it breaks out of the vacuum pipe.
At this time, Su Changli had brought Li Qingye to the control room.
Seeing that the vacuum degree of the pipeline had reached the standard, Baisha immediately ordered: "Start the circular acceleration!"
The power supply system inside the base injects surging electrical energy into the electromagnetic accelerator.
This electromagnetic accelerator is the equipment responsible for acceleration, and the Huozhizhi itself has no electromagnetic acceleration components.
The electromagnetic accelerating frame clamped the Huozhong and began to accelerate along the ring-shaped accelerating pipe.
From the initial 10 meters per second, in less than 10 minutes, the speed has increased to 500 meters per second.
At this time, the electromagnetic accelerating frame has run almost half a circle in the ring pipe, and the length of this ring pipe is 300 kilometers.
The speed of the electromagnetic accelerator rack is getting faster and faster. After running several times in the ring pipe, the speed is finally increased to the limit of 7800 meters per second.
"Start changing course."
The staff presses the track change switch, and the control system automatically adjusts the track to connect the oblique curved pipelines of the ring-shaped pipeline.
7 seconds later.
The electromagnetic accelerating frame slides along the track into the inclined curved pipe. This is also the last section of the electromagnetic accelerating pipe.
When the electromagnetic acceleration frame enters the hard pipe of the column-type vacuum pipe, the fire number automatically ignites instantly at an altitude of 1,500 meters.
Vacuum pipes make no sound.
But Li Qingye still saw the ignition moment of the Huozhong through the temperature sensor data.
At this time, the tail flame and exhaust gas generated by the ignition of the Huozhong are sprayed on the bottom plate of the electromagnetic accelerator, which just slows down the electromagnetic accelerator.
The Spark maintained a speed of 7.8 kilometers per second and flew upward along the vacuum hard tube.
Then break through the hard pipe and enter the vacuum hose area.
The speed of 7.8 kilometers per second was astonishing. The 26-kilometer-long vacuum hose area was crossed by the Spark in just over three seconds.
Bo!
The Tinder penetrates the insulating membrane above the pipe.
However, the Huozhi, which was already at an altitude of 30,000 meters, did not reduce its speed. The power of burning at a low flow rate was enough to overcome the gravity of the earth.
After all, the density of air at an altitude of 30,000 meters is very small, and it is almost a vacuum.
Moreover, as the Spark flies higher and higher, the earth's gravity and the air resistance of the atmosphere will become smaller and smaller, which means that the power required by the Spark will become smaller and smaller.
9 seconds after breaking through the barrier film.
The Ignition crossed the Karman Line.
"Core-level separation!"
The core stage of the Spark is separated from the Spark. The Spark space train still weighs 6,000 tons. Since this mission is in the middle orbit, the payload of the Spark is 3,600 tons, and the rest is between fuel and auxiliary engines.
kind.
The thrown core first stage was not scrapped. Instead, it used the remaining 500 tons of fuel, constantly adjusted its descent speed, and finally landed on the northeast coast of Motor Island, where there is a special space landing site.
Compared with other conventional launch vehicles, the core stage of the Huozhizhuan can be used at least about 50 times.
On the one hand, it is because of Homo sapiens' unique integrated manufacturing technology, and on the other hand, it is also because of the vacuum pipeline and electromagnetic acceleration, which themselves cause relatively little damage to the Fire Seed machine body.
at the same time.
After the Tinder broke out of the Karman Line.
That machine with a length of 50 meters and a diameter of 10 meters simply scares the world.
Compare it to the Falcon Heavy launch vehicle. The Falcon Heavy launch vehicle has a take-off length of 70 meters and a rocket body diameter of 3.6 meters. With two boosters, the take-off weight is about 1,400 tons.
When the Spark flew beyond the Karman Line, it was roughly equivalent to the take-off weight of a four-engine Falcon Heavy.
As long as the Huozhong's body shape data can be detected, the payload of the Huozhong can basically be determined.
Obviously, the world's major aerospace agencies and intelligence agencies, which are paying close attention to the Homo sapiens company, are naturally incompetent and cannot even analyze this kind of data.
The Spark did not linger in low-Earth orbit, but adjusted its orbit twice through the auxiliary engine, and then flew directly to the middle orbit.
This time the mission of the Spark is to go to the Homo sapiens space station.
Although it was a test mission, Su Changli, who was full of confidence, obviously had no intention of wasting the payload of this launch mission.
The Spark will stay at the Homo sapiens space station and become the main axis of the homo sapiens space station.
