Ming Dynasty and New Rome and Infinite Magic Machine

Chapter 1320 Track Construction
Perhaps it was due to the protection of the dragon egg, or perhaps Shangluo was particularly lucky today, the firecracker plan was successful.

"Wow!" Wen Yuan looked up at the sky. "What the hell is this? Where did this boat go?"

"It was launched near the space station and docked with it."

"Wait a minute." Wen Yuan asked, "Based on my high school physics knowledge, this thing has no speed, so it will fall down even if it is launched, right?"

"So I sent it to the vicinity of the space station in high orbit. When it was attracted back by the Earth from high orbit, the space station used the 'rotation' property of the Vulcan core to make it fly past the Earth, using the Earth's gravity as a gravitational slingshot to regain the time to accelerate, thus slowly rounding the elliptical orbit."

This process is pure magic. Shangluo had already calculated that there is nothing in the world that can put a battleship of nearly 0 tons into orbit. Just as Wen Yuan said, there is no zero gravity in space, and things without speed will fall even in space.

But in the process of falling, the speed is accelerated by the gravity acceleration of the earth, that is, 9.8 meters per second. If you want to enter orbit, you have to reach the first cosmic speed, which is 7900 meters per second.

To reach this speed, the uniform acceleration formula shows that if an object wants to enter orbit, it needs to accelerate at the standard gravitational acceleration of the Earth for 807 seconds, which is about 13 minutes.

This is impossible to achieve because the direction of the Earth's gravitational acceleration must point to the Earth's center of mass. If the spacecraft is allowed to fall, then even if it reaches the first cosmic speed, it will only hit the Earth at the first cosmic speed.

So another kind of magic of Vulcan Core is needed here - rotation.

The Vulcan core can make the warship rotate. Not only does the warship rotate itself, but its forward direction also "rotates", so that after getting enough gravitational acceleration for free, it can turn the bow and let the ship fly past the earth, converting the speed pointing to the earth into the speed around the earth.

After that, jump back to the original height and you can fall down again.

In fact, if the Vulcan device is powerful enough, this rotation can achieve a right-angle turn. But the Vulcan device now tied to the back is only a civilian version and does not actually have enough direct orbital capability.

In order for this behemoth to reach a speed fast enough to orbit the earth, and in order for the battleship to effectively accelerate for 807 seconds in the gravity field, the battleship also needs to change its trajectory frequently in the universe, including using a gravity slingshot to extend the opportunity for acceleration.

During this process, the Vulcan device can only concentrate energy on rotation and cannot provide excessive propulsion, so the main force of acceleration is still the gravity of the earth itself.

Although 807 seconds is only about 13 minutes, considering various reasons, such as the fact that the gravitational acceleration decreases when moving away from the earth, the entire orbit entry and subsequent orbit change actually takes more than ten hours. Within a dozen hours, many places on the earth can see a huge object flying around the edge of the earth.

“This is too thrilling!”

"So this is why the moon is so important. To launch such a large structure on the moon, you don't need to use this kind of tricks with firecrackers and gravity slingshots - but then again, this is also because the ship itself is so big."

"By the way, can you see that ship if you look up?"

"I haven't really calculated where I can see it. But the scheduled orbit is on the path of Lan Fang's lunar cannon. After a series of equipment is launched, the battleship will also be equipped with more powerful Vulcan devices, and then we will be able to move forward more freely."

"This is really...totally magic! Is this magical space travel?"

"This seems to be an idea of ​​the Romans. However, the Vulcan device was not reliable at this time, and they had no way to guarantee that the ship would be safe during this series of operations - but." Shangluo shook his head.

This reminded him of the many weapons that had a bad reputation in history, but they shined in video games. This was because the tanks and light weapons in video games would not malfunction. In this case, even the Saosha machine gun would look handsome.

Under the protection of the dragon egg, the Vulcan device will no longer collapse and can perform its mission completely.

"Shangluo." Wen Yuan looked at the sky. He had noticed that the warship appeared above his head.

It was a high orbit far from the ground, and a huge object visible to the naked eye was heading straight for the ground. However, before entering the atmosphere, the entire ship strangely and firmly made a big turn, with the bow pointing upward, and then jumped to a high orbit again, and fell again.

The battleship was bouncing back and forth on the border between reality and magic. It would be successful in a dozen hours.

"Should we also prepare?" Wen Yuan asked, "This time, the Lianshan will be our base of operations, right?"

"Yes. But we won't take the jump device. We can just take a regular rocket."

According to current plans, there are three launch methods that serve the goal together.

One is the pure magic launch just now by Lianshan. This can only be used by Lianshan, because it is impossible to jump so many times in a row without exploding in other places.

The second is the cargo lunar cannon.

The third is the manned Water Dragon.

All three methods were huge, working together for a grand goal. At this point, the advantages of the planned route also emerged - the carrying capacity of these three methods was extremely large. Even the slowest water dragon could launch 400 metric tons at a time after a preparation period of more than ten days.

If the lunar cannon keeps firing continuously, it can launch hundreds of tons of materials into space every three days. Both of these conventional methods can project huge masses into orbit in a short period of time.

The track construction of Lianshan will also start accordingly, and many automatic machines and manual operators will go to Lianshan to install them.

A temporary dock will be built near the space station so that equipment and supplies can be gathered and distributed there.

"We just need to eat well and sleep well." Shangluo replied, "These are all automatic. The preliminary work has been handed over to the automaton and Tianyi Guiren. We will join the action after the preliminary environment is built. When we join, the plan will begin."

"Are you planning on launching some escort ships or something?"

"I actually applied for two Shuilongs. By then, there will be two 2-ton Shuilong-modified frigates next to us. Well, it looks like we have a fleet."
