Tyrannosaurus Rex Industries is now too big.

There are too many fields involved in white feather whale technology. It is impossible to bow down to everything.

What should be thrown to others, it is still necessary to throw it to others.

It's like a tiltrotor.

Knowing that Rune Ou is unreliable, he has to hand it over to him.

Why?

Wang Buan didn't want to exhaust himself.

He now has a lot of R&D tasks. I definitely don't want to get involved with a tiltrotor anymore.

"When are you going to deliver?"

"In a few days. ”

"So fast?"

"Of course. These are extraordinary times. ”

"That's right. ”

Wang Buan nodded approvingly.

Indeed, these are extraordinary times. Everything has to be fast.

R&D should be fast.

Production should be fast.

Delivery should be fast.

Otherwise, the market will be seized by others.

Now the demand for long-range artillery has skyrocketed. The market outlook is very good. But there are also quite a few competitors.

Long-barreled artillery from the United States, from Germany, and from France are all sought-after goods in the international market.

There are also polar bears that also have a relatively fixed circle of arms friends.

Huaxia is just a latecomer.

If you want to grab the market, you must overtake in corners.

Only one PLZ-45 self-propelled gun is clearly not enough. More types are needed.

Fortunately, Chai Lufeng had already prepared for it.

They focus on ultra-long range.

All guns, the caliber ratio is above 60.

And the competitor's artillery, the caliber ratio is about 50 at the maximum. This alone gives you an advantage.

What are the advantages of increasing the caliber ratio? Of course, the firing range has increased by a large margin.

The caliber ratio of the PLZ-255 heavy gun is 75, which increases the firing range by at least 30%.

Together with the highest level of propellants, it is possible to hit a distance of 130 km.

If the caliber ratio is only 45, the maximum range is estimated to be about 60-70 kilometers.

Range is very important.

Especially in these special times.

If you use it as a shore defense gun, the longer the range, the better.

Otherwise, Ta Wu would not have hurriedly led people to find Wang Bu'an. Orders won't be placed quickly.

PLZ-255 super heavy artillery alone, an order for fifteen battalions was placed.

According to the calculation of 18 heavy guns per battalion, that is a full 240 guns!

And, this is just the beginning.

Orders will definitely come one after another.

According to conservative estimates, selling 1,000 units is not a problem at all.

With a little promotion, 3,000 sets is not difficult.

The oceans are becoming less and less safe now.

The number of those varieties of octopus will definitely increase. The lethality will also increase. They will become a growing threat to the oceans.

If there is no strong enough military force, there is certainly no way to expel them.

However, this is a matter of Chailu Peak.

He, Wang Buan, just drank a mouthful of soup.

Now, the most important thing is to come to Shi Zhongjian.

To change the Bull Demon King transport plane into a space shuttle!

Hurry up and call Shangguan Yuqiang.

called Han Xuewei again.

The three of them got on the Little Golden Dragon helicopter together.

Set your destination.

7404 factory.

Takeoff.

On the way, Shangguan Yuqiang called Shi Zhongjian to inform Wang Bu'an's itinerary.

Shi Zhongjian is also wealthy now.

Well, that's right, the 7404 factory has been assigned to the management of Shi Zhongjian.

This guy didn't care who was the factory director before, so he just gave it away. The current 7404 factory has a new director.

It turned out that the director of the factory seemed to be called Fan Baocheng, right? Where was he kicked now? The ghost knows.

"What? Chief Engineer Wang is coming?" Shi Zhong insisted on.

"Yes. Shangguan Yuqiang replied calmly.

"Okay. I immediately rushed to the 7404 plant. ”

"We'll be there in about two hours. ”

"Understood. ”

"Goodbye. ”

Shangguan Yuqiang hung up the phone.

She looked out the porthole. The white clouds are rapidly receding.

I have to say that modern technology is really getting more and more magical. Even helicopters don't need people to drive them anymore.

As long as the coordinates are set, it can fly automatically. Nothing to worry about.

It will automatically dodge obstacles. There will be no crashes.

Even if dozens of small golden dragons are gathered together, they can fly in an orderly formation.

Wang Buan seems to have obsessive-compulsive disorder?

As long as the two Little Golden Dragon helicopters are together, they must be neat and orderly.

How do you say that? It's a two-person line, and a three-person line.

The distance between a helicopter and a helicopter is almost the same.

No alternative situations are allowed.

I didn't expect this guy to have such an old-fashioned side. What age are they?

She was wrong.

This is not Wang Buan's obsessive-compulsive disorder.

This is obsessive-compulsive disorder from the Transformers race.

As a mechanical race, the Transformers place great importance on order. It has also been committed to maintaining order.

They do not allow others to challenge the established order.

Not of any race.

Two hours later, the Little Golden Dragon helicopter landed safely.

The nuts in the stone are waiting.

He also came by helicopter.

The same is the Little Golden Dragon helicopter. It's also autonomous driving.

"Hello. ”

"Hello. ”

Simple greetings.

Straight to the point.

Wang Bu'an explained his intention.

Shi Zhongjian nodded, indicating that there was generally no problem.

The basic structure of the space shuttle is similar to that of the Bull Demon King transport plane. But the materials used are different.

Considering the special environment of outer space, stainless steel is obviously not suitable.

Either titanium alloys are used.

Either all of them use cemented carbide of grade 3 or higher.

Titanium alloys are relatively lightweight.

Tungsten carbide above grade 3 has a high safety factor.

Cosmic rays or something, in fact, there is no need to worry. It couldn't break the shuttle.

However, those damn ultra-miniature meteorites are possible.

Or maybe it's called a meteorite shower.

Many meteorites are only the size of a fist. Even only the size of an egg. But it's very destructive.

They fly too fast, often above 10 times the speed of sound. This is equivalent to a disemboweled shell! If it hits a satellite, the satellite will be destroyed. If the shuttle is hit, there is also a chance that the shuttle will be destroyed. From this point of view, the titanium alloy is not strong enough to resist the attack of meteorite rain.

If it is a cemented carbide above grade 3, it is different. Its defense is very strong.

Even a 120-mm tank gun can't penetrate it.

A small meteorite, as powerful as a cannonball.

Of course, it would be best if you could use grade 5 cemented carbide.

Using the highest grade 6 hard carbide as the bone, and using the 5th grade hard carbide as the skin, this defense is the strongest.

However, the weight of cemented carbide is relatively large. If all of them were used, the space shuttle would weigh more than 100 tons. The requirements for the powertrain are very high.

And the first cosmic velocity requirement 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 reached.

In fact, the biggest difference between the space shuttle and the Bull Demon King transport aircraft is the power system.

As long as the powertrain is modified, everything else is easy to do.

"It's up to you. Shi Zhongjian said.

"Let's use titanium. Wang Buan said slowly.

He now has only one nuclear fission reactor engine with a thrust of 200 tons.

Of course, with his current faith value, he can also buy two similar engines. In the case of triple packing, the total thrust can reach more than 600 tons.

However, it would have been possible to build three space shuttles, but now only one can be built, which is certainly not cost-effective.

Wang Buan has already thought about it. A space shuttle with only one nuclear fission engine installed.

Otherwise, the number of nuclear fission engines needed is too great to be satisfied.

It's just that he needs a lot of space shuttles!

Otherwise, how do you transport people and supplies?

What's more, he has too much titanium alloy in his hands.

There are so many industrial parks, and there are already a lot of titanium alloys accumulated.

Don't say tens of thousands of tons, I'm afraid there are tens of millions of tons. But they are all hoarded and not exposed for the time being.

Otherwise, the price of titanium alloy in the world will immediately fall to the price of cabbage.

It will be easy to make a large submarine out of titanium alloy.

Not to mention the construction of a few titanium alloy submarines, it is enough to build 10,000 of them!

In particular, if the three marine industrial parks are liberated, they will be able to produce millions of tons of titanium alloy every day. The data is insane.

Now Wang Buan is completely a capitalist. Don't let too much titanium alloy enter the market.

But in general, the price of titanium alloys is still decreasing.

In the past, it was hundreds of thousands of yuan per ton, but now it has been reduced to tens of thousands of yuan per ton. It's almost the same as copper alloys.

There is no problem at all in building a space shuttle out of titanium.

There are still three issues that need to be addressed:

"First, oxygen. ”

"Second, pressure. ”

"Third, gravity. ”

Why is the Space Shuttle special?

Because it requires some very special equipment.

Take oxygen, for example.

There is no oxygen in outer space.

However, personnel need oxygen to breathe. Without oxygen people die.

What to do?

Oxygen, of course.

With current technology, the quantities of oxygen manufactured are limited.

Once the predetermined time came, it was necessary to retreat. Otherwise, oxygen cannot be supplied. Problems arise.

Water molecule synthesizers can make oxygen.

But it needs raw materials.

There is no air in outer space, so it cannot run continuously.

It needs to carry certain raw materials. The main thing is pure water. Break down the water to get some oxygen. Some oxygen can also be obtained by converting the decomposed hydrogen into oxygen.

Finally, after breathing, carbon dioxide is produced. Partial oxygen is also obtained by converting carbon dioxide into oxygen.

Overall, this problem is relatively easy to solve.

Severe hypoxia does not arise.

The second problem is normal stress.

There is no air in outer space, and there is 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 be shattered. Straight to the end of the life.

Therefore, the interior of the shuttle must be maintained at a normal atmospheric pressure. The minimum should not be less than 70%.

How does this pressure come from? It has to be with special equipment.

This device needs to be coordinated with Project 591.

After all, the 591 project is the most professional aerospace research center.
