The next day, Huang Junjie took Fan Chengan and others by boat to Caiyu Island.
Because the research and development projects here are quite sensitive, the security force is very strong, and when the mass projector projects objects, there may be dangers, such as the problem of the projectile falling back to the ground.
Therefore, the Electromagnetic Ejection Research Institute is built underground, and even the mass projector is underground, which is somewhat similar to a mushroom egg launch silo.
In order to build this research institute, a mountain of more than 100 meters on Caiyu Island was hollowed out.
Fortunately, Academician Ma and the others chose a small angle to tilt the projectile at a small angle during the experimental test, so that when the projectile fell back to the ground, it fell into the sea.
Inside the Electromagnetic Launch Research Institute.
"Mr. Huang, long time no see!" Academician Ma smiled and shook hands with Huang Haojie.
After Academician Ma developed the electromagnetic catapult before, he also tested the electromagnetic catapult several times. I heard that the latest No. 002 will use an electromagnetic catapult.
But later, Academician Ma proposed a mass projector, an enhanced version of the electromagnetic catapult, and wanted to project satellites or spacecraft into outer space.
However, this idea was rejected by the Academy of Sciences and the Aerospace System. After all, they had not thought about the mass projector, but they were short of money and the technical conditions did not meet the requirements. In addition, Galaxy Technology's normal temperature superconductor had not been completed at that time.
Academician Ma also didn't have much hope for the Academy of Sciences and the aerospace system, so he was invited by Huang Haojie to work at Galaxy Technology.
After arriving at the Electromagnetic Ejection Research Institute of Galaxy Technology, Academician Ma quickly became involved with the researchers at Galaxy Technology.
Especially with the breakthrough of room-temperature superconductors, coupled with the improvement of strong magnetic repulsion materials and other technologies, mass projectors have become more and more mature thanks to the efforts of Academician Ma and others.
…
Huang Junjie looked inside the huge launch silo. A mass projector about 150 meters high was pointing at the sky like a cannon.
The entrance of the launch silo was closed at this time, so the blue sky and white clouds outside could not be seen.
This mass projector is composed of six normal-temperature superconductor rails, forming a regular hexagonal track.
On the side is a regular hexagonal space capsule that has been prepared in advance and is ready to go.
Of course, due to its testing nature, this space capsule is just a superficial thing.
"Academician Ma, what are the parameters of this space capsule?" Huang Haojie came to the space capsule and realized that this thing was very huge.
"This space capsule is a regular hexagonal cylinder with a side length of 3 meters and a height of 12 meters. The volume is 462 cubic meters and the mass is 34 tons." Academician Ma introduced excitedly.
"Then let me take a look at your mass projector!"
"no problem."
After a while, all the staff began to check various systems and install the test capsule into the orbit of the mass projector.
Under the thick reinforced concrete layer on the other side is the control room of the mass projector.
"Have you reported it to the aviation department?" Huang Haojie asked the person in charge of the institute.
"It has already been reported."
All work in the control room is proceeding in an orderly manner.
"All ground monitoring stations are ready."
"All tropospheric airship monitoring stations are ready."
"The stratosphere..." "The mesosphere..."
"The power reserve of the power storage station is 100%."
…
"The weather is sunny, the air humidity is 74%, and the air temperature is 19 degrees Celsius..."
"Everything is normal in the launch airspace and there are no other aircraft."
Academician Ma listened to the reports from various departments and found that there were no problems, so he said loudly:
"Everyone is in position and entering the countdown to launch."
[Beep! The launch countdown begins] A cold electronic sound sounded immediately.
60…20…10…
A powerful current was instantly input from the power storage station into the mass projector. The six superconducting rails and the strong magnetic repulsion base at the bottom began to generate a powerful Lorentz force.
If the space capsule had not been braked by the braking device, it would have flown out long ago.
The cover of the launch silo has already been opened.
8…3…1,0.
Poof...phew...this is the sonic boom generated by the space capsule breaking through the speed of sound.
Huang Junjie looked at the control instrument. The initial projection velocity of the space capsule reached 5518 meters per second, which is equivalent to 16 times the speed of sound.
As the space capsule climbs rapidly, altitude and speed are inversely proportional, that is, the higher the altitude, the slower the speed.
Finally, the space capsule reached an altitude of about 94,457 meters, then lost power and began to be pulled back to the ground by the planet's gravity.
"Get ready for landing." Academician Ma shouted quickly.
Monitoring airships scattered in the airspace around the launch silo, as well as ground monitoring stations, quickly captured the space capsule that was quickly returning to the ground.
"Enter 60 kilometers."
"Enter 50 kilometers."
…
"Enter 15 kilometers."
"Start the deceleration system."
At this time, the space capsule that was flying above the launch silo received instructions from the ground.
The six decelerated hydrogen and oxygen engines at the bottom of the capsule started quickly.
Poof... blue flames spurted out from the engine nozzles. Although the power of these engines was not large, it was still possible to slow down the falling speed of the space capsule.
"Entering 12 kilometers, the speed has dropped to 320 meters per second."
"Activate the airbag system."
The top of the space capsule that had just rushed down into the troposphere popped open instantly, and its six airbags quickly inflated.
These six airbags are made of high-strength elastic films. As for the filling gas, it is hydrogen released from submetallic hydrogen. In addition, the airbags have been filled with passivating agent in advance to avoid hydrogen deflagration and explosion.
By the time the airbag was fully deployed, the space capsule had descended to less than 5 kilometers above the ground.
However, at this time, due to the buoyancy of the hydrogen airbag and the thrust of the hydrogen-oxygen engine, the capsule's descent speed has become slow.
"Correct the descent direction."
The six hydrogen and oxygen engines slowly adjust the descent direction of the space capsule to the designated position by constantly changing the thrust direction.
Ten minutes later.
Caiyu Island is located on the seaside in a flat reinforced concrete land of about 10,000 square meters.
After correcting its orientation, the space capsule slowly docked in mid-air in the middle of the flat ground.
Three pairs of supports stretched out from three sides of the space capsule, and then the engine stalled.
Bump! The support frame of the space capsule gently kissed the ground, and the hydraulic rod on the support frame cushioned the impact.
The controller in the control room quickly started the airbag recovery system.
The hydrogen gas inside the air bag is re-solidified into a submetallic hydrogen state, and the air bag shrinks back.
The recovery platform has a concrete road leading to the bunker base, and a specially modified large crane platform slowly drives out of the bunker base.
Then pull the space capsule back into the bunker base.
Huang Haojie came to the recycling center with Academician Ma and the head of the research institute.
Dozens of staff are busy assessing the situation of the space capsule.
The heat insulation layer outside the space capsule was almost completely worn away by the strong air friction, leaving it completely black.
"Not bad! It's in line with my expectations." Huang Haojie knew that the mass projector and space capsule could be put into use after modifications.
"Mr. Huang, I thought I could push the space capsule to about 100 kilometers this time, but I didn't expect that it would only reach about 94 kilometers." Academician Ma said with some embarrassment.
Because Academician Ma was not aware of Huang Haojie's vacuum pipeline plan, he was not satisfied with the projection height of the mass projector.
If we follow the performance of the mass projector in front of us and combine it with a vacuum pipeline, especially the troposphere and stratosphere, this mass projector can definitely project a 34-ton space capsule to a distance of 150 to 200 kilometers.
in low-Earth orbit.
At the position of 150 to 200 kilometers, using the hydrogen-oxygen engine, the outer space near the Blue Star can almost come and go freely.
That's why Huang Haojie said that it was in line with expectations. If the Karman Line space station is built, it can definitely reach more than 300 kilometers with one shot.
