"Centrifugal, centrifugal space station ......"

Claire flipped through the introduction of the Qianqian space station on the official website of Xinyuan Aerospace Power, and at the same time started to write and draw on paper.

The centrifugal space station is no stranger to every astronaut, but it is too troublesome to build, not to mention anything else, just a few hundred tons of mass to be launched into low-earth orbit assembly, two conditions must be met:

Heavy rockets, space shuttles.

The former launches the module, and the latter installs a truss.

The rotation of such a heavy space station is a serious challenge for the interface, even if it is a completely closed-loop link like Xinyuan, it must be equipped with a steel structure truss to be used with confidence.

Space shuttle? The three remaining STS have been restarted, although the condition is not good, but it can be used, the huge amount of money spent when it was manufactured was not in vain, if it were not for the high cost, the space shuttle can really fly 100 times of life, and the impact of a few years is not too great.

And what about heavy rockets? In order to save costs and speed up, it is best to reuse, this is also available, specaX Heavy Falcon will do.

It can hit more than 40 tons of load in the case of reuse, and it is no problem for the 3.4-meter-diameter rocket body to hit the cabin with a diameter of about 5 meters, so the transportation capacity is sufficient, and it can also be launched at high frequency.

Two heavy falcons are rotated, one shot a month is absolutely fine, and capacity is not an obstacle.

There is no need to have as many 12 centrifugal cabins as in the Advance, one compartment in the center, four to six centrifugal cabins are enough, and there is no need to connect with each other, the mass of about 250 to 350 tons is enough, and the truss will not exceed 400 tons.

That is, the weight of an ISS, but it can also carry out a mission with about 8 astronauts.

What tasks to perform? Landing on Mars, of course!

Although Lin Ju claimed that the Qianjin space station was just a simple space station, as a permanent test site for low-earth orbit personnel, if he really believed it, he would be fooled.

Spending a lot of energy, counting the Space Shuttle to install at least 20 giant rocket launches, just for this? Ghost believes!

It must be the government's instructions to land on Mars or even other planets to be willing to invest such a large amount of resources, absolutely!

Then there is no doubt that NACA will follow up, and the Endeavor space station will definitely be put into use in 2018 or before, so that is to say, after the manned landing on the moon announced by China, it will be prepared for two years at most, and the manned landing on Mars will definitely be planned from 2020 onwards!

Think about it, if they really launch an unmanned probe to Mars in 2018 and the preparatory materials for a manned landing in 2020, they will be able to carry out a manned landing mission in 2022.

And at that time, the Enary space station had been in practical use for four years, and there was enough time for testing and refinement, as long as the propulsion module was added, it was a qualified spacecraft!

In other words, NACA is going to start the manned landing mission at the same time as the SLS is expected to carry out the first manned mission to the moon?!

bullshit！

If NACA is to build its own centrifugal space station, it will have to be completed by 2020, and it will be planned almost now.

Claire casually estimated that it was another $10 billion in spending.

Although she thinks every day that she doesn't have enough money, Claire also knows that Congress can't spend money on space endlessly, and she still has to try to reduce spending as much as possible.

Then, it is necessary to see if there is any way for private space companies.

Immediately, NACA announced internally that it was soliciting designs for space stations that could provide gravity from major corporations.

……

"Is the kerosene here made in China?"

"Yes, the thousands of tons of fuel refueled for Xinyuan-3 are all refined and produced by Karamay Petrochemical, which is the only aerospace kerosene manufacturer in China."

With the development of the YF100 project, China began to study high-purity aerospace kerosene, although there is no low-sulfur oil field directly discovered by the alliance, but because of the progress of refining technology, it is still easy to get high-purity aerospace kerosene technology.

This was originally intended for the Long March 5, but in fact, the first rocket to fly into the sky using it was Xinyuan-1, and Karamay Petrochemical is also an old partner of Xinyuan, from whom a lot of aviation fuel and gasoline were obtained cheaply.

Seryov listened to the staff's answers, and seemed to be able to smell kerosene through the body of the arrow.

Liquid oxygen methane, liquid oxygen, liquid hydrogen, liquid oxygen kerosene, the three main engines are so clean, why cling to those toxic, heavily polluting and expensive fuels?

Selyov remembered that in his previous life he competed with Cherome for the moon landing program, and he gave the design of the N1, and Cheromet came up with the UR700 giant rocket.

Dubbed the "Chelomé's Big Baby", the UR700 is a super-poison hair, and its first stage engine is nine magical RD270 engines.

The main fuel and oxidizer of RD270 are metamethylhydrazine and nitrogen tetroxide, with a specific impulse of 301 seconds and a thrust of 640 tons.

It is even expected to be used during the landing on Venus, starting in the nightmarish atmosphere of Venus, which rains sulfuric acid all year round.

UR700 has a low-earth orbit capacity of more than 150 tons and a take-off mass of more than 4,900 tons, a proper giant rocket, but Seryov and Korolev are extremely disgusted.

In addition to personal vendettas, the RD270 combustion chamber also produces cyanide! It's a real poison, and it's really brain-pumping to release this thing in the atmosphere.

However, at that time, because only the NK33 engine of the OKB-276 design bureau was in hand, the N1, a violent rocket with 30 150-ton kerosene engines, finally failed.

However, the use of 19 400-ton liquid oxygen kerosene engines in the Xinyuan-3 has made up for his shortcomings, and this rocket with a take-off mass of 5,900 tons is regarded by him as the spiritual heritage of N1, environmentally friendly and reliable, how good.

As for Xinyuan-4, it is a typical American thinking, the core-level hydrogen and oxygen machine plus solid boost, it is too expensive, and Seryov does not like it very much.

Standing with thousands of students in a separately demarcated priority viewing area, the young Seryov was not noticeable, and no one noticed that Xinyuan's second-in-command was standing here, just looking at the fairy Xinyuan No. 3 expectantly.

To be precise, the two rockets this time should be called Xinyuan No. 3 A, because they are both two-stage configurations, that is, the three-stage configuration was simply and rudely removed, and the capacity is sufficient anyway.

Today's launch is the pilot module and the node module, and the two modules plus the fairing allow the height of Xinyuan-3 to break through 160 meters and nearly 170 meters high.

In addition, the diameter of the cabin is 14 meters larger than the 11 meter diameter of the arrow body, which looks extremely tall and stout, which is converted into a skyscraper, and according to the floor height of 3.2 meters, it is 50 stories high!

At this time, the actual weight of Xinyuan-3 with the load has exceeded 6,000 tons, and every minute and second is breaking a new record for human rockets.

When the 19 engines were ignited one after the other, the flames formed by the 7,700-ton thrust converged instantly filled the diversion groove and sprayed out of the diagonal upward channel, covering an area of nearly one kilometer around the launch station.

Hundreds of new students who entered the school truly felt the power they would have in the future.
