Super technology leader

The scene of the "Sea Dragon Giant Beast" leaping out of the sea does indeed fit the romantic sentiments of spaceflight, but unfortunately, humans have pragmatism in addition to romantic sentiments.

When many people form a space agency and move towards one or several goals, it is impossible for it to stop for one person's romantic sentiments.

People once thought that it could only stay in science fiction works and people's imaginations, as a permanent witness to human's unconstrained imagination and eternal innovation, but no one thought that today, they would actually see a similar super rocket.

Yishan(移山: Yishan, name of the rocket) Super Rocket!

Its diameter reaches 20 meters, its height exceeds 160 meters, and its weight after being filled with fuel reaches 10,360 tons.

If we use the Sea Dragon rocket as an analogy, then it is a thin and tall version of the Sea Dragon, a model-figured Sea Dragon, or a Gao Fushuai(高富帅: tall, rich, and handsome) version of the Sea Dragon.

The reason why it is called a Gao Fushuai(高富帅: tall, rich, and handsome) Sea Dragon is not because its carrying capacity is stronger than that of the Sea Dragon. In fact, its orbital carrying capacity is only 280 tons, which is far worse than the Sea Dragon's 550 tons.

Even if there is a difference in overall weight, comparing the respective carrying ratios of 0.027 to 0.03, it is still not as good as the Sea Dragon.

The carrying ratio is the comparison between the payload and the take-off mass. The larger the number, the better the performance of the rocket.

After all, if two rockets are not recovered or are recovered, one with a take-off mass of 1000 tons can carry 20 tons, and one with a take-off mass of 1000 tons can carry 30 tons, it is obvious that the one that carries 30 tons is better.

The reason for saying that is because, compared to the "born at the wrong time" and "technically flawed" Sea Dragon, the Yishan(移山: Yishan, name of the rocket) appeared at the "right time", and the technology is completely fine. It is really good, easy to use, and cheap.

Tianxia(天夏: Tianxia, name of the country) is about to enter the era of large-scale space construction, and the 280-ton near-Earth orbit carrying capacity far exceeds the current Long March 9 modified, which is the strongest carrying capacity on Earth, and it will definitely make a big difference.

The main thing is that its diameter is very large, reaching 20 meters.

With a diameter of 20 meters and a height of 160 meters, its booster is 90 meters high and its carrier is 70 meters high, so its cargo hold size is directly set to 20 meters by 40 meters, which is very huge.

The folded small gravity cabin with a diameter of only 15 meters, which was launched by the "Giant Far航(巨头远航: Giant Far Sailing) Adventure", is more than enough to load it, and it is not a problem to load a folded medium-sized gravity cabin.

According to Tang Chao's vision, the unfolded diameter of the medium-sized simulated gravity cabin is 50 meters, and the folded state is 18 meters.

The connection channel between the rotating shaft and the arc-shaped cabin is mainly folded and unfolded. After handling it, the size of the rotating shaft and the arc-shaped cabin is not too important, as long as it can be used.

Therefore, the advantage of the Yishan(移山: Yishan, name of the rocket) super rocket is the huge cargo hold and reusability. If it is built, the 280-ton load is considered the world's largest, but that is not its most prominent advantage, or there is nothing to boast about.

After all, its carrying ratio is only 0.027, which is not outstanding among a group of rockets with a carrying ratio of 0.04 or even 0.05.

Well, the Sea Dragon's 0.03 is also mediocre, but it can't stand its violent. The carrying capacity of 550 tons makes people excited to death.

However, the recovery method of Yishan(移山: Yishan, name of the rocket) rocket is more flexible and complete than that of Sea Dragon rocket.

The Sea Dragon rocket consumes all the fuel, and then uses an inflatable deceleration airbag to decelerate and land on the sea for recovery, which is similar to landing with a parachute.

The advantage of this recovery method is that the rocket's carrying capacity is wasted very little, but it is very rigid. Although there is deceleration, it still has to smash into the sea, and the vibration caused to the rocket is also difficult to control.

The Yishan(移山: Yishan, name of the rocket) cannot use up all the fuel. Its recovery method is to ignite the engine multiple times to cushion the landing, so it needs to retain some fuel, and the carrying capacity is wasted more.

If the booster responsible for take-off wants to land back to the landing field near the launch pad, it needs to retain a lot of fuel. If it lands on a large recovery ship, it only needs to retain very little fuel.

The carrier carrying the goods will enter the orbit. It will stay in orbit for a period of time. If it wants to return to Earth, it can choose a suitable re-entry point, and it can smoothly land at a landing field not far from the launch pad with a small amount of fuel.

This convenient recovery capability is due to a new rocket engine, which Tang Chao named - Feisheng(飞升: Ascension)!

Um.

Yishan(移山: Yishan, name of the rocket)!

Feisheng(飞升: Ascension)!

Very suitable.

Tang Chao explained that their names come from "Yugong Yishan(愚公移山: The Foolish Old Man Removes the Mountains)", which tells the story of an old man who persevered in digging mountains and moving mountains, and then moved God, and the gods sent Hercules to descend to earth, and then carried the mountains to ascend and move them.

It was not inspired by a certain "Dawei Tianlong(大威天龙: a chant)" video he accidentally saw while "archaeologizing" on Bilibili.

To Yishan(移山: Yishan, name of the rocket), the thrust of the Feisheng(飞升: Ascension) engine must be large, so its single thrust reaches 600 tons.

This single thrust is certainly not the largest on Earth, but it is the most suitable.

A total of 25 Feisheng(飞升: Ascension) engines are integrated on the booster of the Yishan(移山: Yishan, name of the rocket) super rocket, which can provide a huge thrust of 15,000 tons, easily lifting the fully loaded Yishan(移山: Yishan, name of the rocket) super rocket with a weight of just over 10,000 tons into the sky.

When it reaches a certain height, the booster separates, and the 7 Feisheng(飞升: Ascension) engines on the carrier ignite, and the 4,200-ton thrust pushes the carrier to fly to the space orbit.

The use of liquid hydrogen and liquid oxygen fuel increases the manufacturing difficulty and cost of the Feisheng(飞升: Ascension) engine, but it gives it a very wide range of applications.

Low altitude, high altitude, vacuum, as long as there is water.

It just so happens that its manufacturing company is Pioneer, so the difficulty is about equal to none, leaving only the benefits.

Now Pioneer has jointly established a base on the moon with the Tianxia(天夏: Tianxia, name of the country) Space Administration, and has discovered a huge ice mine. Hydrogen and oxygen fuel extraction equipment has also been launched. The Benyue(奔月: fly to the moon) spacecraft can carry fuel from the moon at any time to provide a certain amount of fuel supply to equipment in lunar orbit and Earth orbit.

Not to mention that the carrier of the Yishan(移山: Yishan, name of the rocket) is itself a spacecraft. The Feisheng(飞升: Ascension) engine is an intelligent engine that can intelligently adjust the thrust. Then it can get rid of the Earth's gravity at high altitude and fly into space, and it is naturally easy to take off on the moon.

Its fuel tank is huge, even if it does not refuel in space, it can still fly to the moon by itself for fuel supply, and take off again for long voyage.

After all, the near-Earth carrying capacity of the Yishan(移山: Yishan, name of the rocket) super rocket reaches 280 tons, and the carrying capacity of the moon and Mars is also 120 tons and 100 tons.

This is still the ability to not refuel in space orbit. If refueling is carried out in orbit, it can transport heavier objects to the moon and Mars.

With its addition, it has very important significance for the construction of Earth orbit, the construction of lunar bases, the construction of Mars bases, and even farther space exploration in the near future, that is, in the next few decades.

Its cargo hold has a diameter of 20 meters, which greatly increases the size range of the modules that can be transported.

In space, the larger the module naturally represents the improvement of comfort, the improvement of range, and the improvement of the complexity of the equipment that can be carried.

Let's put it this way, it only needs to be launched three times, and the modules it transported can assemble a formal spacecraft to Mars in space orbit.

In Tang Chao's latest plan, the Mars spacecraft is more than 100 meters long, equipped with a medium-sized simulated gravity hold with an unfold diameter of 50 meters, uses advanced ion thrusters, and can fly to Mars within a month when it is close to Earth.

This spacecraft can carry 10 astronauts, two Mars landers, a Mars survival hold that accommodates 10 astronauts for a month, and several simple Mars transportation vehicle.

This is Tang Chao's latest plan. The plan name is already in the company's manufacturing sequence, but the specific content has not been updated. As long as he updates the content, this spacecraft will be added to the manufacturing sequence.

These are all the work to be done later. He will not announce it at this conference. After all, this conference is mainly about the Tianting(天庭: Heavenly Court) Space Station, supplemented by the Yishan(移山: Yishan, name of the rocket) Super Rocket.

Don't look at the super rocket adding the word "super" and weighing 10,000 tons, which is 4 times heavier than the space station's approximately 2,500 tons, but most of its weight is liquid hydrogen and liquid oxygen fuel, which is very "watery".

However, after he finished talking about the Yishan(移山: Yishan, name of the rocket) rocket, the reaction on the scene and on the Internet seemed to be more intense than when the Tianting(天庭: Heavenly Court) Space Station was announced before.

He was puzzled for a moment, but immediately reacted.

"Humans are indeed visual animals."
