Chapter 630: space shuttle

Tyrannosaurus rex industries are now too big.
White feather whale technology involves too many fields. It is impossible to do everything personally.
Things that should be thrown to others should be thrown to others.
It's like a tilt rotor plane.
Knowing that Runeou was unreliable, he had to give it to him.
why?
Wang Buan didn't want to exhaust himself.
His current R&D tasks are already very much. I definitely don't want to be contaminated with the tiltrotor.
"When are you planning to deliver?"
"A few days later."
"So fast?"
"Of course. This is an extraordinary period."
"Right."
Wang Bu'an nodded in agreement.
Indeed, it is an extraordinary period right now. Everything must be fast.
R&D must be fast.
Produce fast.
Delivery must be fast.
Otherwise the market will be seized by others.
Now, the demand for long-range artillery is skyrocketing. The market prospects are very good. But there are many competitors.
The long barrel artillery from the United States, Germany, and France are all sought-after goods in the international market.
Polar bears also have a relatively fixed circle of arms friends.
Huaxia is just a latecomer.
If you want to grab the market, you must bend overtaking.
Only one type of plz-45 self-propelled artillery is obviously not enough. More types are needed.
Fortunately, Chai Lufeng was already prepared.
They focus on super long range.
All guns have caliber ratios above 60.
The maximum caliber ratio of competitors' artillery is around 50. This alone has an advantage.
What are the advantages of increasing the caliber ratio? Of course, the range has been greatly increased.
The caliber ratio of the plz-255 heavy gun is 75, which increases the range by at least 30%.
With the most advanced propellant, it can reach a distance of 130 kilometers.
If the caliber ratio is only 45, the maximum range is estimated to be about 60-70 kilometers.
Range is very important.
Especially in the current special period.
If used as a shore defense gun, the firing range is definitely the farther the better.
Otherwise, Tawu would not rush people to find Wang Bu'an. Will not place orders quickly.
For the plz-255 super heavy artillery alone, an order for fifteen battalions was placed.
Calculated on the basis of 18 heavy artillery pieces per battalion, that is a full 240!
Moreover, this is just the beginning.
Orders will definitely come one after another.
It is conservatively estimated that selling 1,000 sets is not a problem at all.
A little bit of promotion, 3000 sets are not difficult.
The ocean is becoming more and more insecure now.
The number of those variants of octopus will definitely increase. The lethality will also increase. Their threat to the ocean will become greater and greater.
If there is not a strong enough military force, there is certainly no way to expel them.
However, this is a matter of Chai Lufeng.
His Wang Buan was just taking a sip of soup.
Now, the most important thing is to find the stone backbone.
Change the Bull Demon Transporter to a Space Shuttle!
Call Shangguan Yu Qiang quickly.
Called Han Xuewei again.
The three people boarded the Xiaojinlong helicopter together.
Set the destination.
7404 factory.
take off.
On the way, Shangguan Yuqiang called Shi Zhongjian to inform Wang Buan's itinerary.
Shi Zhongjian is also rich now.
Well, yes, the 7404 factory is already under the management of Shizhongjian.
This guy doesn't care who was the factory manager before, so he just touched him. The current factory 7404 has been replaced by a new factory director.
It turns out that the factory manager is called Fan Baocheng, right? Where are you kicked now? The ghost knows.
"What? Chief Engineer Wang is coming?" Shi Zhong insisted.
"Yes." Shangguan Yuqiang answered calmly.
"Okay. I'll rush to the 7404 factory immediately."
"We will arrive in about two hours."
"understand."
"Goodbye."
Shangguan Yuqiang hung up.
She looked outside the porthole. Blossoming white clouds are retreating quickly.
I have to say that modern technology is really getting more and more amazing. Even the helicopter doesn't need people to pilot it.
As long as the coordinates are set, it can fly automatically. No matter what.
It will automatically avoid obstacles. Will not crash.
Even if dozens of small golden dragons gather together, they can fly in orderly formation.
Wang Buan seems to have obsessive-compulsive disorder?
As long as the two Little Golden Dragon helicopters are together, they must be in order.
how to say? It is two people in a row and three in a row.
The distance between helicopter and helicopter is almost the same.
No alternative situations are allowed.
Unexpectedly, this guy also had such a staid side. What age is it? Also make this uniform.
She was wrong.
This is not Wang Buyan’s obsessive-compulsive disorder.
This is an obsessive-compulsive disorder from the Transformers race.
As a mechanical race, Transformers attaches great importance to order. Has also been committed to maintaining order.
They do not allow others to challenge the established order.
No race will work.
Two hours later, the Xiao Jinlong helicopter landed safely.
Nuts in the stone are waiting.
He also came here by helicopter.
The same is the Little Golden Dragon helicopter. It is also autonomous driving.
"Hello there."
"Hello there."
Say hello simply.
Go directly to the topic.
Wang Bu'an explained his intention.
Shi Zhongjian nodded, indicating that there is generally no problem.
The basic structure of the space shuttle is similar to that of the Bull Demon Transport Aircraft. But the materials used are different.
Considering the special environment of outer space, stainless steel is obviously inappropriate.
Either use a titanium alloy.
Either all use hard alloys above grade three.
Titanium alloys are relatively light.
Cemented carbide above grade 3 has a high safety factor.
There is no need to worry about cosmic rays. It has no way to smash the space shuttle.
However, those deadly ultra-miniature meteorites are possible.
Or it is called a meteorite shower.
Many meteorites are only the size of a fist. Even the size of an egg. But the destructive power is very large.
Their flight speed is too fast, often more than 10 times the speed of sound. This is equivalent to a shell out of the chamber! If it hits the satellite, the satellite will be destroyed. If it hits the space shuttle, the space shuttle may also be destroyed. From this point of view, the strength of titanium alloy is not enough, it will certainly not be able to withstand the attack of meteorite rain.
It is different if it is a grade 3 or higher cemented carbide. Its defensive ability is very strong.
Even the 120mm tank gun cannot penetrate.
A small meteorite is as powerful as a cannonball.
Of course, it would be best if you can use grade five hard alloy.
The use of the highest grade six hard alloy as the bones and five grade hard alloy as the skin, this kind of defense is the strongest.
However, the weight of cemented carbide is relatively large. If used all, the weight of the space shuttle itself would exceed 100 tons. The requirements for the power system are very high.
And the requirement of the first universe speed is more than 25 times the speed of sound. If the weight is too large and the power is too small, the speed cannot be achieved.
In fact, the biggest difference between the space shuttle and the Bull Demon Transport aircraft is the power system.
As long as the power system is modified, everything else is easy to handle.
"You decide." Shi Zhongjian said.
"Let's use titanium alloy." Wang Bu said calmly.
He currently has only one nuclear fission reactor engine with a thrust of 200 tons.
Of course, for his current belief value, he can also purchase two other similar engines. With triple installation, the total thrust can reach over 600 tons.
However, it was possible to build three space shuttles, but now only one can be built, which of course is not cost-effective.
Wang Bu'an has already thought about it. A space shuttle only has one nuclear fission engine installed.
Otherwise, the number of nuclear fission engines required is too large to meet.
It happened that he needed a lot of space shuttles!
Otherwise, how do you transport people and supplies?
Besides, he has too much titanium alloy in his hand.
So many industrial parks have accumulated a lot of titanium alloys.
Not to mention tens of thousands of tons, I am afraid there are tens of thousands of tons. But they are all being hoarded and have not been exposed for the time being.
Otherwise, the world's titanium alloy prices will immediately fall to the price of cabbage.
It's easy to use titanium alloys to make large submarines.
Not to mention building a few titanium alloy submarines, it is enough to build 10,000 ships!
In particular, if the three marine industrial parks are liberated, they can produce millions of tons of titanium alloy every day. The data is crazy.
Wang Bu'an is now a capitalist. Do not let too much titanium alloy flow into the market.
But in general, the price of titanium alloys is still falling.
It used to be hundreds of thousands of yuan per ton, but now it has been reduced to tens of thousands of yuan per ton. Almost equal to copper alloy.
There is no problem at all with titanium alloys to build space shuttles.
There are three problems to be solved:
"First, oxygen."
"Second, pressure."
"Third, gravity."
Why is the space shuttle special?
Because it requires some very special equipment.
For example, oxygen.
There is no oxygen in outer space.
However, people need oxygen to breathe. Without oxygen, people will die.
How to do?
Of course it is to make oxygen.
With current technology, the amount of oxygen produced is limited.
Once the scheduled time is reached, you must retreat. Otherwise, oxygen cannot be supplied. There will be problems.
The water molecule synthesizer can produce oxygen.
But it needs raw materials.
There is no air in outer space, so it cannot operate continuously.
It needs to carry certain raw materials. The main thing is pure water. Decompose water to get part of oxygen. By converting the decomposed hydrogen into oxygen, part of the oxygen can also be obtained.
Finally, after breathing, carbon dioxide is produced. Part of the oxygen can also be obtained by converting carbon dioxide into oxygen.
In general, this problem is relatively easy to solve.
The problem of severe hypoxia will not occur ~EbookFREE.me~ The second problem is normal pressure.
There is no air in outer space and almost no pressure. The human body cannot bear it.
If there is no normal atmospheric pressure, the human body will burst. All blood vessels, organs, and cells will all burst. He died directly.
Therefore, the interior of the space shuttle must maintain a normal atmospheric pressure. The minimum cannot be less than 70%.
How does this pressure come from? Must use special equipment.
This equipment needs to be coordinated with Project 591.
After all, Project 591 is the most professional aerospace research center.
