There are many terms for rocket launches.

Of these, the terms about orbit are the most numerous.

The so-called orbit is actually different heights. There are so many grades.

The higher the track, the more difficult it is to reach.

The thrust of the fat five is indeed very large.

However, the real transport capacity is not strong.

The carrying capacity of the Long March 5B is only about 25 tons. It was the Tianhe core module that was transported.

So, where is its huge thrust used?

Quite simply, it was used in the rocket itself.

It requires a lot of strapping rockets.

It requires a very large amount of propellant. There are more than 130 tons of propellant alone.

After reaching a certain height, it will also separate step by step, throwing away the useless parts to reduce its own mass.

As a result, after arriving in outer space, the fat five have become the little five.

Obviously, Xiao Wu's own motivation cannot be very strong.

Its travel time in outer space is limited.

Figuratively speaking, it is a big fat man, carrying a lot of food, eating all the way, throwing it all the way, and in the end there is not much left. If you want to do something, you can't do anything.

Why build a space station in outer space? It's to give this big fat man a little food so that he can move on.

Unfortunately, the fuel in the space station also needs to be sent by rockets.

The cost is still very high.

One launch of Ariane V (EU) will cost about $220 million.

One launch of Cosmos 5 (USA) will cost about $190 million.

One launch of the Delta 4 Heavy (USA) will cost about $265 million.

Polar bears are slightly cheaper, about $100 million.

So far, the Fat Five has only been launched twice.

Both times were flight test missions. As a result, it succeeded in 2016 and failed in 2017.

At that time, when the rocket flew for 252 seconds, the flight state was abnormal. When the flight reached 346 seconds, the turbine exhaust device of one of the two YF77 liquid hydrogen and liquid oxygen engines in the first stage of the core was abnormal in the complex mechanical and thermal environment, and the thrust of the engine decreased sharply instantaneously, resulting in the rocket being unable to reach the predetermined flight speed and altitude, and finally the second stage of the rocket and the satellite crashed in the western Pacific Ocean, and the launch mission failed.

"Send 100 tons of supplies to the moon...... "Lomagawa's face gradually became solemn.

"That's right!" Wang Buan said affirmatively, "We can do it!"

Delta Heavy IV ......

"Better than it. ”

For his own strength, Wang Buan is very confident.

For earthlings, landing on the moon is indeed very difficult. Only the power of a poor country can do it.

However, the current level of science and technology of earthlings is still relatively limited.

The Delta IV Heavy is the largest launch vehicle in service and in service in the United States, and it can deliver up to 28.79 tons of payload into low-Earth orbit. 11 tons of payload were put into geosynchronous orbit, where the communications satellite is located. It has also been reported to be able to send 11 tons of payload to the moon and 8.8 tons of payload to Mars orbit.

This rocket, which claims to be the most powerful rocket of mankind at present, can only send 11 tons of supplies to the moon.

However, Wang Buan was able to send 100 tons at a time!

It can also be used over and over again!

It is also possible to fly multiple shuttles at the same time!

"I can make more ultra-miniature nuclear fission reactors. Wang Buan said quietly.

"More space shuttles?" Lomachuan blurted out.

"That's right!"

"Oh my God!"

Lomachuan shook his fist hard.

What is the biggest obstacle to the development of the space shuttle? In fact, in the final analysis, it is a question of funding.

Really, this thing is too expensive.

Even the big superdog in the United States is unbearable.

The U.S. initially budgeted $43 billion (converted to 2011 dollars) for the Space Shuttle program, which was expected to cost $54 million per launch, but the plan was well over budget due to the complexity of the shuttle system (more than 2.5 million parts of the fuselage) and the significant amount of manpower and material resources required for technical and system maintenance. Statistics as of 2011 show that the space shuttle program cost a total of $196 billion, of which each shuttle cost about $12 billion, a single launch cost about $450 million (nearly 10 times more than budget), and a single-use spacecraft cost only $2.3 billion.

In 2005, nearly 30 percent of NASA's funding, about $5 billion, was spent on the Space Shuttle. In 2006, that figure fell to $4.3 billion, with ground maintenance on the Space Shuttle accounting for a large share. Between 2004 and 2006, the shuttle was launched only three times because of the Columbia accident, but NASA still spent $13 billion on the program.

It's tens of billions of dollars at every turn!

Cost 12 billion US dollars......

It costs $450 million for one launch!

Such a terrifying cost is impossible for Huaxia to bear for the time being.

It is estimated that the scientific research funds received by the space center since its establishment are not enough to build a space shuttle.

Since the space shuttle is so expensive, now, the Americans have retired it.

Since then, the space shuttle has officially withdrawn from the stage of history.

Wang Bu'an is now proposing to build a space shuttle, is it a bit against the current?

"We can provide the technology. ”

"However, it is absolutely impossible for us to provide funding. ”

Liang Wannian said bluntly, "Building a space shuttle is completely your commercial behavior. ”

Wang Bu said with peace of mind: "Don't worry, I will pay for the relevant technology." As long as the price you offer is not outrageous. ”

In fact, Wang Buan is capable of building a space shuttle by himself. There is no need for the space center to intervene at all.

His industrial park and robot elves are fully capable of this.

However, he wasn't prepared to go it alone.

Boring.

Playing a single-player game?

Cheating is cool for a while, and I won't be interested in it later.

In this project, it is better to pull the space center as a way to earn more faith points.

For him personally, faith is worth more than money.

"By the way, it's not convenient for us to participate in this matter openly. Liang Wannian said cautiously.

"Why?" said Wang Bu'an didn't understand.

What's inconvenient?

The space center does not steal or rob.

"Not your own outrageous remarks?" Mr. Lomachuan said.

"Me?" Wang Buyan frowned.

"You said you wanted to divide the moon, right?"

"Yes. ”

"Then do you think the country is suitable for mixing?"

"Understood. ”

Sure enough, it doesn't fit.

Because the state is about political correctness.

But his remarks are obviously contrary to this political correctness.

So what to do?

Of course, let Wang Buan toss it himself.

The state put all the blame on Wang Buan.

After really going to the moon in the future, the biggest fat will of course be given to the country.

What is it called?

is still the most professional back-stabber.

"Then you can't do nothing, right?" Wang Bu'an said sullenly.

"Whatever you want, we can provide it. Gratuitous. Lomachuan said slowly, "But if someone asks, we will never admit it." ”

"Yes. Got it. ”

"Do you really understand?"

"Totally understood. ”

"Deal. ”

"Deal. ”

The two shook hands pleasantly.

Immediately, Luo Machuan, who had always been serious, slowly shook his head.

Such an outcome, of course, is not what he wants to see. It would be nice if the space center was in charge!

However, if it is the state, it will have to abide by many United Nations treaties.

Among them are many contracts involving the sovereignty of the moon.

We can't afford not to obey it!

The set of "since ancient times" cannot be developed on the moon.

You can't take Chang'e, Yutu, Wu Gang, and Osmanthus as examples. Other foreigners don't even know what Chang'e is.

If you say that the moon has been the territory of China since ancient times, there is a chance that people will roll their eyes.

However, if it is operated by Wang Buan, it will be fine.

He's a businessman!

He does not represent a country.

It's a big deal, openly "criticize" Wang Buan a few words.

It's all innocuous and insignificant. The most important thing is to run to the moon as soon as possible. Preemption is the main one.

What is the law of appropriation?

It's not just a matter of planting a national flag.

Send a great crowd up.

To build a settlement on the moon.

It is necessary to establish a Chinese residential area on the moon in a decent way.

Note that it is a residential area. Not an immigration area. It's a permanent stay.

Then consciously exclude the populations of other countries. Gradually, over time, we can take the entire moon for ourselves.

This is definitely not what Huaxia thinks alone.

Other countries think the same way, 100 percent.

It's just that no one else has the ability to immigrate on a large scale for the time being.

Otherwise, the current moon would have been divided up by a certain or several countries long ago. The latecomers can't even gnaw a little bit of the scum.

"In this matter, your White Feather Whale Technology is in front of the stage. We are behind the scenes. Lomachuan told repeatedly.

"Got it. I'll handle it on a high note. Wang Buan understood.

"Good. Happy to work with. ”

"It was a pleasure to work with. ”

Shi Zhongjian turned around and discussed the details with Luo Machuan.

Wang Bu'an is going to the next stop again.

But it was Chai Lufeng who called.

The PLZ255 Super Heavy Gun is to be tested for the last time before delivery.

This time the test place is a bit special.

It was installed on the coast and launched at the sea in the distance.

"I'll go. ”

"Come on!"

Of course, Wang Buan is going to be there.

Anyway, it is also a barrel provided by itself. It is necessary to see how it works in practice.

This kind of 75 times caliber cannon barrel can only be produced in Wang Buan's industrial park. If the effect is good, it must be to increase production!

Didn't the Transformers complain that the industrial park was not fully loaded?

From now on, it will be fully loaded.

Whatever it is, produce it first.

For example, this 75 times caliber barrel will be produced first 100,000 pieces. Feel free to use it. You can use as much as you want.

In addition, there are 100 times the caliber, 125 times the caliber, 150 times the caliber, 200 times the caliber of the barrel, also produced a large number of first. If necessary, you can use it for testing.

What? I've never seen a 100-caliber barrel? Okay, I'll show you now.

Don't say it's 100 times the caliber. It's 500 times, 1000 times I can figure it out.

With Transformers technology, this is completely no problem.

Otherwise, they will die of shame.
