The scene of the "sea dragon monster" jumping out of the sea is indeed very in line with the romanticism of aerospace, but unfortunately, in addition to romanticism, human beings also have pragmatism.

When a large number of people make up a space agency, and it is advancing for one or several goals, it is impossible for it to stay for the romantic feelings of one person.

Once thought that it could only stay in science fiction works and people's imagination, as a permanent testimony to the unbridled imagination and eternal innovation of human beings, no one expected that today, they would see a similar super rocket.

Moving Mountains Super Rocket!

It has a diameter of 20 meters, a height of more than 160 meters, and a weight of 10,360 tons when refueled.

If you use the sea dragon rocket as an analogy, then it is a thin and tall version of the sea dragon, a sea dragon with a model body, or a rich and handsome version of the sea dragon.

It is said that it is a rich and handsome sea dragon, not that 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 550 tons of the sea dragon.

Even if there is a difference in overall weight, it is not as good as the sea dragon when compared to 0.027 and 0.03 according to their respective carrying ratios.

The payload ratio is the comparison of the load and take-off mass, and the higher the number, the better the performance of the rocket.

After all, if both rockets are not recovered or both are recycled, a take-off mass of 1000 tons can transport 20 tons, and a take-off mass of 1000 tons can transport 30 tons, and it is obvious that it is good to transport 30 tons.

It is said that it is because compared to the sea dragon that was "born at the wrong time" and "has technical shortcomings", the appearance of the Yishan was "at the right time", and the technology is completely fine, it is really easy to use and cheap.

Tianxia will soon enter the era of space construction, and the 280-ton low-earth orbit carrying capacity far exceeds that of the Long March 9, which has the strongest carrying capacity on the earth at present, and will definitely make great achievements.

The main thing is that it has a large diameter, reaching 20 meters.

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

The small gravity capsule in the folded state that the "Giant Voyage" ventured to launch before was only 15 meters in diameter, which was not only more than enough to fit it, but also a medium-sized gravity capsule in a folded state.

According to Tang Chao's assumption, the medium-sized simulated gravity cabin has a diameter of 50 meters when unfolded and 18 meters when folded.

The main thing is that the connecting channel between the hinge and the arc cabin is folded and expanded, and after it is processed, the size of the rotating shaft and the arc cabin is not too important, and it can be used.

So the advantage of the Yishan super rocket is the huge cargo compartment and reusability, if it is built, although the 280-ton payload is the largest in the world, but that is not its most prominent point? Or rather, there is nothing to boast about.

After all, it only has a carrying ratio of 0.027? In a crowd of 0.04? Even a rocket with a 0.05 carrying ratio is not outstanding.

Well, Sea Dragon's 0.03 is also mediocre, but it can't stand people up to be violent enough? A look at the carrying capacity of 550 tons is too high.

But the recovery method of the Yishan rocket is more flexible than that of the Sea Dragon rocket? Better.

The Sea Dragon rocket uses up all the fuel, and then uses an inflatable deceleration airbag to slow down to the sea for recovery, which is similar to descending with a parachute.

The advantage of this recycling method is that the rocket capacity is wasted very little, but it is very dull? Although there is a slowdown, but still have to be smashed into the sea? The vibration caused by the rocket is also difficult to control.

And the Yishan can't use up all the fuel, and its recovery method is that the engine ignition multiple times to buffer the landing, so you need to keep some fuel? There is a lot of waste of capacity.

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

The cargo carrier will enter orbit, it will stay in orbit for a while, and if it wants to return to Earth, it can choose a suitable re-entry point, and it can smoothly land with a small amount of fuel to the landing site not far from the launch pad.

This convenient recovery capability is made possible by a new rocket engine, which Tang Chao named - Soaring!

Well.

Move mountains!

Soaring!

It's a good fit.

Tang Chao explained that their names come from "Yugong Moving Mountains", which is the story of an old man who persevered to dig mountains and move mountains, and then moved the heavens.

It wasn't that he accidentally saw the inspiration of a certain "Dawei Tianlong" video when he was beeping "archaeology".

To move mountains, the thrust of the ascension engine had to be large, so its single thrust reached 600 tons.

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

A total of 25 ascension engines are integrated into the boosters of the Yishan super rocket, which can provide a huge thrust of 15,000 tons, and easily lift a fully loaded Yishan super rocket weighing more than 10,000 tons into the sky.

When it reaches a certain altitude, the booster is disengaged, the seven ascension engines on the launch vehicle are ignited, and the thrust of 4,200 tons pushes the launch vehicle to space orbit.

Although the use of liquid hydrogen and liquid oxygen fuel makes it more difficult and expensive to manufacture the Ascension engine, it gives it a wide range of applications.

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

However, its manufacturing company is the leader, so the difficulty is about equal to nothing, and only the benefits remain.

Now that the Navigator has established a base on the moon with the Tianxia Space Agency, a huge ice mine has been discovered, and hydrogen and oxygen fuel refining equipment has also been launched, and the Lunar Spacecraft can take off from the moon with fuel at any time to provide a certain amount of fuel supply for equipment in lunar orbit and earth orbit.

Not to mention that the launch vehicle of Yishan itself is a spaceship, and the ascension engine is an intelligent engine, which can intelligently adjust the thrust size, so 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 canister is so large that even if it is not refueled in space, it can still fly to the moon on its own to refuel and take off again for a long voyage.

After all, the near-Earth carrying capacity of the Yishan super rocket reached 280 tons, and the carrying capacity of the Moon and Mars also reached 120 tons and 100 tons.

This is still the ability to carry out refueling in orbit without refueling in orbit, which can carry heavier things to the Moon and Mars.

With its addition, it is of great significance to the construction of earth orbit, moon base, Mars base, and further space exploration in recent decades, that is, in the near future.

With a cargo compartment diameter of up to 20 meters, the range of modules that can be carried has been greatly increased.

In space, larger modules naturally represent increased comfort, increased range, and increased complexity of portable equipment.

Let's put it this way, it only takes three launches for the modules it carries to form a full-fledged spacecraft in space orbit to Mars.

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

The spacecraft can carry 10 astronauts, two Mars landing vessels, a Martian survival module that can accommodate 10 astronauts for a month, and several improvised Martian scooters.

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

This is all the work to be done later, and he will not announce it at this press conference, after all, this meeting is still based on the Heavenly Court Space Station, supplemented by the Yishan Super Rocket.

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

However, after he finished talking about the success of the Yishan rocket, the repercussions on the scene and on the Internet seemed to be more intense than when the Heavenly Court Space Station was announced before.

He was puzzled for a moment, but immediately reacted.

"Humans are really visual creatures."
