My Super Black Technology Empire

To put it bluntly, this thing is that the smaller the gravity loss, the better, so that the engine specific impulse disadvantage of the gas generator F-1 is basically completely avoided.

Because the second-stage kerosene engine flies for 2.5 minutes, it is basically thrown away, so the dead weight of the second-stage basically no longer exists.

No matter how it is designed, the sooner the first stage and the second stage are thrown away, the better. Under normal circumstances, the first stage engine has the largest dead weight. However, this rocket in the design drawing is different. This is the second stage with the largest dead weight.

At this time, the three-stage engine begins to fall off, and the advantage of specific impulse is gradually reflected. One of the advantages of specific impulse is to use less fuel to achieve higher speeds.

The third-stage rocket is a hydrogen-oxygen engine with a high specific impulse, and then the third-stage rocket engine will send the entire rocket out of the atmosphere, but it cannot reach a low synchronous orbit.

So at this time, the fourth-stage engine starts to operate, and the fourth-stage is also a hydrogen-oxygen engine, inheriting the speed brought by the thrust of the third-stage engine, and flying directly to the low-synchronous orbit.

High synchronous orbit and low synchronous orbit are determined by the distance from space to the ground.

Generally speaking, the low geosynchronous orbit is the daily orbit of some weather satellites, spy satellites, and communication satellites.

Because whether it is the electromagnetic waves of communication, or the various sensors and cameras on the spy satellite, the lower the distance from the ground, the better, but it can't be too low, otherwise it will fall.

The hypersynchronous orbit is the daily orbit of various equipment such as the space station, such as the International Space Station "Soyuz", China's space station "Tiangong", and the Hubble Space Telescope.

Generally speaking, whether it is a low synchronous orbit or a high synchronous orbit, it will slowly fall into the atmosphere, but the time is different.

Therefore, equipment such as space stations in high synchronous orbits are generally equipped with engines to prevent them from falling into low synchronous orbits.

If the space station falls into a low synchronous orbit, it will be finished, because the space station itself is very large, and the engine on the space station alone is not enough to push it back to the high synchronous orbit.

Therefore, the parts of the mining spacecraft need to be transported to a hypersynchronous orbit, waiting for the next rocket launch, to be assembled in space.

To be honest, Ye Fan's mining spacecraft is more advanced than the space station. At that time, the mining spacecraft will start the electromagnetic propulsion engine and fly directly to the moon.

"Although this design is good, there are still many loopholes. For example, using the ion engine to push it to high altitude and then ignite it in the air, then this is definitely a serious test for the stable attitude of the rocket."

"Yeah, Dr. Zhao is right. If it is ignited in the air, then the rocket is top-heavy, and it is very likely that it will become a missile and smash directly into the ground."

"What's more, the size of the ion engine is very small, only the size of a palm. If it is forced to provide thousands of tons of thrust, the pressure of the engine itself on the material will increase, which is still a test for our existing materials. "

......

At this time, you were talking in the conference room, and Su Ying didn't think about these problems when she came up with this plan.

The reason why she said it here is to brainstorm and let everyone solve the problem. If it really doesn't work, you can only change to another plan.

"Mr. Ye, what do you think of this design?" At this time, Su Ying also set her sights on Ye Fan.

"No, no, if I know how to design rockets, I'll go into battle and draw sketches myself." Ye Fan also shook his head and said with a smile.

As the saying goes, there are specialties in the art industry, and professional things should be left to professional people to do.

With the black technology in Ye Fan's system, it is enough for him to design an epoch-making rocket, and it is like the recyclable rocket of Musk's company.

However, if a company has come up with one or two technologies, it can already be regarded as the heaven-defying, three or four epoch-making black technologies, and it can also be called the son of heaven.

If black technology is thrown out one after another like dumplings, then it is not something that is against the sky, but a monster.

Humans will not have respect or worship for monsters, but will only change their ways to destroy them.

"It's just that I can talk to the professors of the Chinese Academy of Sciences quite well, so I got a new cosmic power engine from them, do you want to hear it?" Ye Fan looked at the crowd and said.

"Well, Mr. Ye, please tell me." Su Ying also said.

After all, with the size of Ye Fan's Datang Technology, it is normal to have a little friendship with the Chinese Academy of Sciences.

They didn't even know that this was just an excuse for Ye Fan's nonsense. This was the engine "Solar Sail" he exchanged from the system.

"According to their new plan, I asked a few old professors and aerospace experts to optimize it. It is still in the experimental stage, and it can start production at Datang Heavy Industry next month."

Ye Fan said, let Yuanyuan connect the holographic projection module on the conference table, and then displayed a new pattern.

"When can we humans fly out of the solar system has always been a matter of great concern to us. At present, the farthest spacecraft we have launched is Voyager 1, which is more than 20 billion kilometers away from us."

"However, even so, Proxima Centauri, the closest star to us, needs to fly for more than 70,000 years. Such a long time is completely unreachable for our lifespan."

"So this is a new type of non-working substance engine called a solar sail, also known as a light sail, which was first proposed by the famous astronomer Kepler four hundred years ago."

Ye Fan pointed to the text on the holographic projection, and then everyone watched intently.

As experts and outstanding graduates in aerospace, they cannot say that they are omniscient and omnipotent, but they basically know a lot about these cosmic propulsion engines.

Therefore, they also know about this solar sail, and it is not a new thing in the industry. However, this thing cannot be made at this stage, and it is useless if it is made.

Four hundred years ago, Kepler thought about the shape of comets and proposed that sunlight can provide a "pressure" that forces comets to form long tails.

If this energy can be used, it may be used for interstellar travel.

In 1978, Euler formally proposed the existence of light pressure, which was finally measured for the first time in 1901 by the Russian physicist Lebedev.
