Homo sapiens.

Chapter 248 Breaking Out of the Carmen Line

22, April 1.

Chin State in the southwestern region of Hongshawady.

Under the cover of a green umbrella system on a plateau near the middle of the Longerang mountains, a behemoth is undergoing final checks.

This is the No. 3 launch site belonging to the space base in Caijin Town.

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

Wu Gang, the head of the base, and Bull, the chief engineer of the Longerang cannon project, were accompanying Li Qingye, looking at the behemoth in front of him.

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 length of 80 meters.

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

"About 50%, after all, this is the first actual measurement." Dr. Bull didn't have much confidence in his heart.

Although their project borrowed a lot of data from the previous "Barbados Cannon" project, and passed a series of supercomputer simulation calculations.

But the super giant gun in front of me has a caliber of 800 mm, and it also uses an unprecedented 100 times the diameter of the barrel.

If Homo sapiens had not possessed the integrated bioalloy material generation technology, there would be no way to produce such a powerful cannon.

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

Although the people in the base are all new humans and soldiers, and there are no people who are hostile to Li Qingye and Homo sapiens, it doesn't mean that Wu Gang is not worried.

Mainly the propellant of the 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 he is here, and Wu Gang will definitely not dare to ask people to prepare the propellant.

On the way to the control room.

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

Dr. Bull shook his head: "It must be ultra-low temperature to ensure safety, even if it is ultra-low temperature, it is actually just extending the shelf life."

The propellant they were talking about was actually metallic hydrogen.

Of course, the metal 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, fullerene is introduced as a catalyst, then electricity is applied, and a pressure of 50 atmospheres is applied to the crystal sponge filled with liquid hydrogen, a piece of metal hydrogen full of impurities can be obtained .

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 metal bonds between the hydrogen atoms will gradually break, and then heat will be released, hydrogen gas will be released, and the lattice structure of the crystal sponge will be destroyed at the same time, and finally it will become a piece of waste material.

That is to say, the metal hydrogen in this unstable state enters a state of constant "depletion" the moment it is manufactured.

Usually, within the first day after the production is completed, the metal hydrogen concentration in the metal hydrogen crystal sponge is the highest, and the concentration can basically be maintained at more than 90%.

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

This is also the usage plan chosen by this base.

So Wu just asked Li Qingye to go to the safe control room. After all, the control room is protected at the level of a nuclear bunker. Even if there is an accident at the base, nothing will happen to the control room.

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

Wu Gang immediately ordered the hydrogen plant in the base to start producing metal 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 shells were inserted, more than half of the liquid oxygen was injected into the explosion chamber at the end of the barrel, and the external refrigeration equipment also started to operate, quickly reducing the internal temperature to minus 180 degrees Celsius.

After half an hour.

control room.

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

Wu Gang turned his head to look at Li Qingye.

Li Qingye waved his hand, signaling him to follow the procedure.

"Begin loading the propellant."

"receive."

The explosion chamber of the gun barrel and the gun barrel itself are not actually integrated, but a split design, just to facilitate the loading of metal hydrogen and liquid oxygen.

After filling the metal hydrogen with a special equipment, use a thin film steel similar to Invar steel to seal the connection port.

Then the gun barrel and the explosion chamber are connected together, similar to the way of the casing, the two parts are completely locked, and then the connection is reinforced with super alloy.

"Start vacuuming."

"receive."

The muzzle of the gun barrel is covered by a special cover and locked tightly. A tiny pipe is designed in the inner wall of the muzzle, and the vacuum is drawn through this pipe.

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

After the vacuuming was completed, the special nano-film on the cover of the muzzle was sucked by the negative pressure and sank a few centimeters into the muzzle.

"Start adjusting the shooting parameters."

"receive."

Kacha... All kinds of mechanical parts are moving slowly. The muzzle of the giant cannon is horizontally based on the sea level, and it is inclined at a 45-degree angle to the southeast sky.

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 security zone with a very high level of protection.

Wu Gang asked the heads of various departments to reconfirm again before announcing: "The countdown to launch is 60 seconds!"

"59..."

"10..."

"1...launch!"

As the button is pressed, the temperature in the explosion chamber rises rapidly in an instant, when the temperature rises to minus 165 degrees Celsius.

Metal Hydrogen has finally gone berserk.

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

And that cannonball was naturally squeezed into the barrel in an instant, and then under the double action of negative pressure and explosion shock wave, it penetrated the membrane of the muzzle in an instant.

boom!With a muzzle velocity of 8.6 kilometers per second, the cannonball smashed into the air instantly, forming a terrifying sonic boom. At the same time, the intense frictional heat made the surface of the cannonball 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 shell peeled off layer by layer in the intense air friction heat.

By the time the shell penetrates the atmosphere and crosses the Karman line, about one-third of the ablative layer remains on the surface.

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

The Indochina Peninsula radar station, the Palawan Island radar station, the Medan Island radar station responsible for monitoring and tracking, and a communication radar ship near Nauru Island.

Quickly reported the location of the shells to the gold mining town space base.

163 seconds later.

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

The total weight of the shell is 7.3 tons. Except for the burned heat-resistant layer and methane liquid oxygen fuel, the various instruments and equipment carried are about 2.8 tons.

The satellite currently has 1.93 tons of fuel left.

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

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