Chapter 229 Projection Experiment
The next day, Huang Haojie took Fan Chengan and others to Caiyu Island by boat.

Because the research and development projects here are quite sensitive, the security force is very strong, and when the mass catapult projects objects, there may be dangers, such as the projected objects falling back to the ground.

Therefore, the Electromagnetic Catapult Research Institute is built underground, and even the mass projector is also underground, which is somewhat similar to the silo of a mushroom egg.

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 to tilt at a small angle during the experimental test, so that when the projected object fell back to the ground, it fell into the sea.

Inside the Electromagnetic Catapult Research Institute.

"Mr. Huang, long time no see!" Academician Ma smiled and shook hands with Huang Haojie.

After Academician Ma developed the electromagnetic catapult, he also tested the electromagnetic catapult several times. It is said that the latest No. 002 will use an electromagnetic catapult.

But later, Academician Ma proposed an enhanced version of the electromagnetic catapult, the mass catapult, and wanted to project satellites or spaceships into outer space.

However, this idea was rejected by the Academy of Sciences and the aerospace system. After all, it is not uncommon for them to have thought about the mass projector. However, they were shy and the technical conditions met the requirements, and at that time, the room temperature superconductor of Galaxy Technology was not completed.

Academician Ma also did not 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 coming to the Electromagnetic Catapult Research Institute of Yinhe Technology, Academician Ma quickly became one with the researchers of Yinhe Technology.

Especially with the breakthrough of room temperature superconductors, coupled with the improvement of strong magnetic repulsion materials and other technologies, with the efforts of Academician Ma and others, the mass projector has become more and more mature.

……

Huang Haojie looked inside the huge silo, a mass projector about 150 meters high, facing the sky like a cannon.

The wellhead of the 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 room-temperature superconductor rails, forming a regular hexagonal orbit.

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 nothing more than a flashy thing.

"Academician Ma, what are the parameters of this space capsule?" Huang Haojie came to the side of the space capsule and realized that this thing is very huge.

"This space capsule is a regular hexagonal cylinder with a side length of 3 meters and a height of 12 meters, with a volume of about 280 cubic meters and a mass of 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 put the test capsule into the orbit of the mass catapult.

On the other side, under a thick layer of reinforced concrete, is the control room for the mass projector.

"Have you reported it to the aviation department?" Huang Haojie asked the person in charge of the research institute.

"It has been reported."

All work in the control room is proceeding in an orderly manner.

"The various ground monitoring stations are ready."

"The tropospheric airship monitoring stations are ready."

"Stratosphere..." "Mesosphere..."

"100% power reserve of power storage station."

……

"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 after finding out that there was no problem, he said loudly:
"Everyone, enter the countdown to launch."

[drop!The launch countdown begins] The cold electronic sound immediately sounded.

60...20...10...

The powerful current is instantly input into the mass projector from the storage power station, and the six superconducting guide rails and the strong magnetic repulsion seat at the bottom begin to generate a powerful Lorentz force.

If it weren't for the space capsule being braked by the braking device, it would have flown out long ago.

The manhole cover of the silo has already been opened.

8...3...1.

Puff... Puff... This is the sonic boom produced by the space capsule breaking through the speed of sound.

Huang Haojie saw that the control was an instrument, and the projected initial velocity of the space capsule reached 5518 meters per second, equivalent to 16 times the speed of sound.

As the space capsule climbs rapidly, the altitude and speed are inversely proportional, that is, the higher the altitude, the slower the speed.

Eventually the capsule reached an altitude of about 94457 meters, then lost power and began to be pulled back to the ground by the gravity of the planet.

"Get ready for landing." Academician Ma shouted hastily.

Surveillance airships scattered in the airspace around the silo, as well as ground monitoring stations, quickly captured the capsule as it was rapidly returning to the ground.

"Enter 60 kilometers."

"Enter 50 kilometers."

……

"Enter 15 kilometers."

"Activate the deceleration system."

At this time, the space capsule that was flying above the silo received a command from the ground.

The six decelerated hydrogen-oxygen engines at the bottom of the capsule started up quickly.

Pfft... Blue flames spewed out from the engine nozzles. Although the power of these engines is not large, it is 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 to the troposphere bounced off instantly, and the six air bags quickly inflated.

These six airbags are made of high-strength elastic film. As for the filling gas, it is the hydrogen released from metallohydrogen. In addition, the airbags have been filled with passivating agents in advance to avoid deflagration and explosion of hydrogen gas.

When the airbag is fully deployed, the space capsule has dropped to less than 5 kilometers from the ground.

But at this time, with the buoyancy of the hydrogen air bag and the thrust of the hydrogen-oxygen engine, the descent speed of the space capsule has become slow.

"Correct the descent direction."

The six hydrogen-oxygen engines continuously change the thrust direction to slowly adjust the descent direction of the space capsule to the designated position.

10 minutes later.

Caiyu Island is located in a flat reinforced concrete land of about 1 square meters by the sea.

After the corrected orientation of the space capsule, it slowly docked in mid-air in the middle of the flat ground.

Three of the capsule bodies on three sides protruded from three pairs of braces, and then the engines shut down.

bump!The support frame of the space capsule gently kisses the ground, and the hydraulic rod on the support frame cushions the impact.

The control personnel in the control room quickly activated the airbag recovery system.

The hydrogen in the airbag is re-solidified into a submetallic hydrogen state, and the airbag shrinks back accordingly.

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 capsule back inside the bunker base.

Inside the recycling center where Huang Haojie came together with Academician Ma and the head of the research institute.

Dozens of crew members are busy assessing the condition of the capsule.

The heat insulation layer outside the space capsule was almost worn away by the strong air friction, and it was completely black.

"Not bad! It has met my expectations." Huang Haojie knew that the mass projector and the space capsule could be put into use after modification.

"Mr. Huang, I thought the space capsule could reach about 100 kilometers this time, but I didn't expect it to reach only about 94 kilometers." Academician Ma said with some embarrassment.

Because Academician Ma didn't know Huang Haojie's vacuum pipeline plan, he was dissatisfied with the projection height of the mass projector.

If the performance of the mass projector in front of us is combined with the vacuum pipeline, especially the distance between the troposphere and the stratosphere into a vacuum state, this mass projector can definitely project a 34-ton space capsule to 150-200 kilometers in low-Earth orbit.

At the position of 150-200 kilometers, and then use 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 met expectations. If the Karmen Line space station is built, it can definitely reach more than 300 kilometers in one shot.
