Homo sapiens

January 6, 22.

In Chin State in the southwest region of Hongsawady.

In a highland near the central Longgrand Mountains, under the cover of a green umbrella system, a behemoth is undergoing final inspections.

This is the No. 3 launch site belonging to the Caijin Town Space Base.

Li Qingye, who recently came to Hongsawady for inspection, also appeared here at this time.

Wu Gang, the director of the base, and Bull, the chief engineer of the Longgrand Cannon Project, were accompanying Li Qingye, looking at the behemoth in front of them.

The shape of this behemoth is like an enlarged version of a battleship turret, with a pipe with a diameter of 800 mm and a pipe length of 80 meters.

Li Qingye looked at the long pipe calmly: "Doctor, how confident are you about this test?"

"About 50%. After all, this is the first actual measurement." Dr. Bull was not very sure.

Although their project borrowed a large amount of data from the previous "Barbados Cannon" project and conducted a series of supercomputer simulation calculations.

But the super cannon in front of us has a caliber of 800 mm, and uses an unprecedented 100-fold barrel.

If it weren't for the Homo sapiens company's integrated bio-alloy material generation technology, there would be no way to produce such a powerful cannon.

"Chairman, let's go to the control room!" Base Director Wu Gang suggested with a slightly worried expression.

Although the people in the base are all new humans and soldiers, and there is no one who is hostile to Li Qingye and Homo Sapien Company, it does not mean that Wu Gang is not worried.

The main reason is that the propellant of the giant cannon is very dangerous.

"Well, let's go to the control room!" Li Qingye is not the kind of person who is inconsiderate of his subordinates. He knows that Wu Gang will not dare to let people prepare propellants here.

On the way to the control room.

Li Qingye asked: "Doctor, is the propellant of the giant cannon still unstable?"

Dr. Bull shook his head: "It must be ultra-low temperature to ensure safety. Even ultra-low temperature actually only extends the shelf life."

The propellant they mentioned was actually metallic hydrogen.

Of course, the metallic hydrogen produced by Homo sapiens is actually a semi-finished product.

Its core technology is a variant of crystal sponge - hydrogen storage crystal sponge.

This kind of hydrogen storage crystal sponge is put into liquid hydrogen, introduces fullerene as a catalyst, then energizes it, and applies a pressure of 500,000 atmospheres to the crystal sponge filled with liquid hydrogen, to obtain a piece of metallic hydrogen full of impurities. .

But this thing must be below minus 175 degrees Celsius to maintain a stable form. Once the temperature exceeds, it will explode instantly.

And even in an environment of minus 175 degrees Celsius, it can only last for 230 to 270 hours.

During this period, the metallic bonds between hydrogen atoms will gradually break, then generate heat and release hydrogen gas. At the same time, the crystal lattice structure of the crystal sponge will be destroyed, and finally it will become a piece of waste material.

In other words, this unstable metallic hydrogen enters a state of constant "exhaustion" the moment it is produced.

Usually within the first day after manufacturing is completed, the concentration of metallic hydrogen in the metallic hydrogen crystal sponge is the highest and can basically maintain a concentration of more than 90%.

Therefore, this kind of metallic hydrogen crystal sponge is best made and used now so that the energy density can be maximized.

This is also the usage plan chosen for this base.

Therefore, Wu just asked Li Qingye to go to a safe control room. After all, the control room has nuclear bunker-level protection. Even if there is an accident at the base, nothing will happen in the control room.

Just after Li Qingye and his party arrived at the control room.

Wu Gang immediately ordered the hydrogen factory in the base to start producing metallic hydrogen.

at the same time.

In the barrel of the giant cannon, a "cannonball" with a diameter of 804 mm was stuffed into it. The reason why the diameter of the cannonball is larger than the caliber of the barrel is mainly for sealing.

After the shell was inserted, more than half of the liquid oxygen was injected into the explosion chamber in the last section of the barrel. At the same time, the external refrigeration equipment also started operating, quickly reducing the internal temperature to minus 180 degrees Celsius.

Half an hour later.

In the control room.

"Report, the metallic hydrogen propellant has been prepared."

Wu Gang turned his head and looked at Li Qingye.

Li Qingye waved his hand, indicating that he should follow the process.

"Start loading propellant."

"receive."

The explosion chamber of the gun barrel and the gun barrel itself are not actually integrated, but are designed in a split style to facilitate the loading of metallic hydrogen and liquid oxygen.

A special equipment is used to fill the metal hydrogen in, and then a thin film steel similar to Invar steel is used to seal the connection.

Then the barrel and the explosion chamber are connected together in a way similar to a casing, completely locking the two parts, and then using super-strong alloy to reinforce the connection.

"Start vacuuming."

"receive."

The muzzle of the gun barrel is covered with a special cover and locked and sealed. A fine pipe is designed in the inner wall of the muzzle, through which the vacuum begins.

Since the diameter of the cannonball is larger than the caliber of the barrel, the cannonball will be firmly sucked during the vacuuming process, but will not slide upward.

After the vacuuming was completed, the special nanometer film on the cover of the muzzle was sucked in by the negative pressure and sunk a few centimeters into the muzzle.

"Start adjusting the shooting parameters."

"receive."

Click... Various mechanical parts moved slowly. The muzzle of the giant cannon was horizontally based on the sea level and tilted toward the southeast sky at a 45-degree angle.

The reason why it is in the southeast direction is that it can take advantage of the acceleration in the direction of the earth's rotation.

Wu Gang looked at the time: "All departments, please pay attention and enter the safe zone immediately."

"receive."

Soon the staff in the base quickly entered the safety area with a very high level of protection.

Wu Gang asked the heads of each department to confirm again before announcing: "The countdown to launch is 60 seconds!"

"59..."

"10..."

"1...Launch!"

As the button was pressed, the temperature in the explosion chamber rose rapidly in an instant, reaching minus 165 degrees Celsius.

Metallic hydrogen finally entered a violent state.

boom! A terrifying explosion occurred in the explosion chamber. Even if it was made of a super-strong composite alloy with a thickness of 1.5 meters and reinforced components with a thickness of 0.8 meters, it still made a shrill roar.

The cannonball was naturally squeezed into the barrel in an instant, and then under the dual effects of negative pressure and explosion shock wave, it penetrated the membrane of the muzzle in an instant.

boom! The muzzle velocity reached 8.6 kilometers per second, and the shell instantly hit the air, forming a terrifying sonic boom. At the same time, the intense frictional heat made the surface of the shell seem to be burning.

A dazzling meteor flew over the Indochina Peninsula at an angle of 45 degrees.

The ablation layer on the surface of the cannonball peels off layer by layer under the intense heat of air friction.

By the time the shell penetrates the atmosphere and crosses the Karman Line, about one-third of the surface ablation layer remains.

And at the moment when the artillery shell flew over the Karman Line, the artillery shell's rocket-increasing engine quickly ignited, and then accelerated to a higher orbit.

The Indo-China Peninsula radar station, Palawan Island radar station, Medan Island radar station responsible for monitoring and tracking, and a communications radar ship near Nauru Island.

Quickly reported the location of the artillery shell to Caijin Town Aerospace Base.

163 seconds later.

The projectile reached a low-Earth orbit of 650 kilometers, and then the rocket engine began to adjust its direction, turning the projectile into an artificial earth satellite orbiting the earth.

The total weight of the artillery shell is 7.3 tons. In addition to the burned heat-resistant layer and methane liquid oxygen fuel, the various instruments and equipment carried weigh about 2.8 tons.

The satellite currently has 1.93 tons of fuel left.

After unfolding the solar panels, the artificial satellite named "Hongsavady 1" officially appeared in the earth's low-Earth orbit.

And during these 163 seconds, the whole world was stunned.
