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

Due to the sensitive nature of the R&D projects here, the security forces are very strong, and the mass projector can be dangerous when projecting objects, such as the problem of the projectile falling back to the ground.

So the electromagnetic catapult research institute is built underground, and even the mass projector is underground, somewhat similar to the silo of a mushroom egg.

In order to build this institute, a mountain of more than 100 meters on Caiyu Island was hollowed out.

However, fortunately, Academician Ma and the others chose a small angle to tilt during the experiment, 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 before, he also tested the electromagnetic catapult several times, and heard that the electromagnetic catapult will be used on the latest 002.

However, after that, Academician Ma proposed the mass projector, an enhanced version of the electromagnetic 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, they did not think about the mass projector, but they were shy and the technical conditions met the requirements, and the room temperature superconductor of Galaxy Technology was not completed at that time.

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 Galaxy Technology, Academician Ma quickly mingled with the researchers of Galaxy Technology.

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

……

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

The wellhead of the silo was closed at this time, so there was no blue sky and white clouds outside.

This mass projector consists of six superconductor rails at room temperature, forming a regular hexagonal orbit.

On the side, a regular hexagonal capsule made in advance is ready to go.

Of course, due to its testing nature, this capsule is nothing more than a façade.

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

"This capsule is a hexagonal cylinder with a side length of 3 meters and a height of 12 meters, with a volume of 462 cubic meters and a mass of 34 tons." Academician Ma excitedly introduced.

"Then let me take a look at your mass projectors!"

"No problem."

After a while, all the crews began to inspect the various systems and load the test capsule into orbit with the mass projector.

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

"You have reported it to the aviation department!" Huang Haojie asked the person in charge of the research institute.

"It's already been filed."

The work in the control room is carried out in an orderly manner.

"The various ground monitoring stations are ready."

"The tropospheric airship monitoring stations are ready."

"Stratospheric ......" "Mesosphere ......"

"100% of the power reserves of the storage station."

……

"The weather is sunny, the air humidity is 74%, the air temperature is 19 degrees Celsius......"

"Everything is normal in the launch airspace, there are no other aircraft."

Academician Ma listened to the reports of various departments, and after finding that there was no problem, he said loudly:

"Ready to go, let's get into the countdown to launch."

[Drop!] The countdown to the launch begins] The icy electronic sound sounded immediately.

60…… 20…… 10……

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

If the capsule hadn't been braked by the brakes, it would have flown out a long time ago.

And the manhole cover of the silo has long been opened.

8…… 3…… 1，0。

Burst...... ...... This is a sonic boom produced by the capsule breaking through the speed of sound.

Huang Haojie looked at the control is instrument, and the muzzle velocity of the capsule reached 5,518 meters per second, which is equivalent to 16 times the speed of sound.

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

Eventually, the 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.

"Ready to land." Academician Ma hurriedly shouted.

The monitoring airships scattered in the airspace around the silos, as well as the ground monitoring stations, quickly captured the capsule, which was rapidly returning to the surface.

"Into 60 km."

"Go 50 kilometers."

……

"Go 15 km."

"Activate the deceleration system."

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

Six decelerated hydrogen-oxygen engines at the bottom of the capsule started quickly.

Burst...... Blue flames erupted from the engine vents, and although the engines were not very powerful, it was possible to slow down the capsule's fall.

"At 12 km/h, the speed has dropped to 320 meters per second."

"Activate the deceleration airbag system."

The top of the capsule, which had just rushed down the troposphere, popped open in an instant, and six air sacs quickly inflated.

These six air bags are made of high-strength elastic films, and as for the filled gas, it is hydrogen released from submetallic hydrogen, and the air bags have been filled with passivator in advance to avoid hydrogen deflagration and explosion.

By the time the airbag was fully deployed, the capsule had descended to less than 5 kilometers above the ground.

However, at this time, the buoyancy of the hydrogen air bag and the thrust of the hydrogen-oxygen engine have slowed down the descent of the capsule.

"Correct the descent."

The six hydrogen-oxygen engines slowly adjust the descent direction of the capsule to the specified position by constantly changing the direction of thrust.

Ten minutes later.

Caiyu Island is located in a 10,000-square-meter reinforced concrete flat land by the sea.

The relocated capsule slowly docked in mid-air in the middle of the flat ground.

Three of the sides of the capsule protruded from the three pairs of supports, and then the engines stalled.

Touch! 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 hurriedly activated the airbag recovery system.

The hydrogen inside the air bag is re-solidified into a submetallic hydrogen state, and the air bag shrinks back with it.

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.

Huang Haojie, Academician Ma, and the head of the institute came to the recycling center.

Dozens of crew members are busy, assessing the situation in the capsule.

The thermal insulation on the outside of the capsule was almost completely wiped out by the strong air friction, and it was black.

"Not bad! It has met my expectations. Huang Haojie knew that this mass projector and space capsule could be put into use if they were modified.

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

Because Academician Ma did not know Huang Haojie's vacuum pipeline plan, he was not satisfied with the projection height of the mass projector.

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

At this position of 150~200 kilometers, and then using the hydrogen and oxygen engine, the outer space near the blue star can come and go almost freely.

That's why Huang Haojie said that it was in line with expectations, and if the Kármán line space station was built, it would definitely be able to reach more than 300 kilometers in one shot.
