Wang Buan is not interested in laser cannons. ．`

Not a sentimental rejection. Rather, I rationally feel that it is not yet hot.

What are the basic conditions for a laser cannon?

Energy reserves.

This thing can be big or small.

In the eyes of others, perhaps a few thousand kilowatts of batteries can be used to emit lasers.

But Wang Buan obviously has no interest in such a laser.

"What is the source of energy?"

"Rock 700 engine. ”

"Hmm......"

Wang Buyan understood.

It turned out that someone felt that the conditions were ripe.

The power of the Panshi 700 engine is still very powerful, a full 100,000k. It can indeed be used to drive the laser.

However, it is only the laser beam that it is urging. It's still far from the "cannon".

Unless it is deliberately confusing the concept. Ordinary laser beams are also included in the scope of "laser cannons".

Theoretical research. It has always been the polar bears who lead.

But in practical application, it is the bald eagle that leads.

The gap between the two is still a bit big. It feels like the polar bear has a high component of mouth cannons.

It is said that it is invincible in the world, and if you do it, you will have a weak heart.

Some researchers in China have also been contaminated with this bad disease.

Obviously it is a very small laser beam, and it is named a laser cannon, and it feels like it has surpassed the United States in an instant.

The lethality of a laser cannon is generally calculated in megajoules. 1 megajoule is 1 million joules. Doesn't that feel like a big number? Actually, it's not that good. Because the joule itself is a tiny, tiny unit of heat. 1 calorie equals 4.184 joules. And an adult needs to consume at least 1400 kilocalories per day. That's close to 6,000 kilojoules, or 6 megajoules.

At present, the most powerful laser weapons in practical use are only 100 megajoules. That is, it is equivalent to the energy consumed by a person in sixteen days.

According to relevant information, the power of many carbon dioxide laser weapons is only 400K.

More often than not, lasers are used as an aid rather than as a regular weapon.

It's not that I don't want to

It's not possible for the time being.

Converting electricity into lasers requires a lot of equipment and materials.

A stable supply of energy is required to emit a laser. During the accumulation period, it cannot be interrupted.

Furthermore.. The cost of a real laser cannon is also very huge. A shot may consume thousands or tens of thousands of kilowatt-hours of electricity. Or even hundreds of thousands of kilowatt-hours of electricity.

If it is a general diesel engine, or a gas turbine, it will definitely not be able to afford it.

At best, it's experimental. Cannot be used in actual combat.

Only a nuclear fission reactor is likely to meet the need.

Of course, the Rock 700 combustible hydrogen engine is also possible.

If a warship is equipped with two Rock 700 engines, it will have a power of 200,000k.

With such a huge amount of power, it must be able to drive a real laser cannon.

"How many laser cannons are you going to install?"

"Six doors. ”

"Triplet?"

"Yes. Two triple launchers. ”

"I'll take a look. ”

Wang Buan came to the test site.

Sure enough, a brand new triple laser emitter was ready.

It looks pretty simple on the outside. It's just a few deep, dark mirrors. This is a very special lens. It is a shaped beam.

Once turned on, the beam bursts out of the lens.

A blazing beam of light that will tear everything apart.

"The power of each laser cannon is about 50,000 k. Pang Xihua said, "At most, you can launch two doors at the same time." ”

"Experiment with it. Wang Buan nodded thoughtfully.

In fact, he is not very optimistic about electromagnetic guns, laser cannons and the like. The main thing is the lack of power.

It's like the laser cannon it encountered before, and even the little spirit dragon helicopter can't shoot it down. At most, it's a laser gun.

Only after the Jinru interstellar era, it is often hundreds of millions, billions, tens of billions of K of power. The laser beam that bursts out like that is the most terrifying.

Of course, there is no need for Wang Buan to say these future details. Otherwise, it will scare people again.

Whether the laser cannon is useful or not. Everything depends on the test of actual combat.

When the machine gun was invented. It is also unpopular. Makqin eats behind closed doors everywhere.

However, after the test of actual combat, the Maxim heavy machine gun has become the weapon that kills the most people in the history of mankind. Not one of them.

Almost half of the casualties of the soldiers of the First World War fell in front of the Maxim heavy machine guns.

When the German chainsaw 42 was invented, it was also ridiculed as ugly and shabby.

But later actual combat proved that it was the best machine gun of World War II. There is also no one.

Who knows if a high-powered laser cannon will shine?

The first test: cutting steel plates.

Ordinary steel plates.

Thickness 100 mm.

"Whew!"

"Whew!"

The laser beam is ejected.

The thick steel plate is easily cut.

The incision is very flat. There are no burrs at all. Touch the ...... with your hands Just kidding!

An incision that has been cut by a laser. The temperature is at least 500 degrees or more.

Reach out and touch it? Don't die......

Replace 200 mm ordinary steel plates.

"Whew!"

"Whew!"

The laser beam is ejected.

The steel plate was cut open again. The incision is generally flat.

But if you look closely, you will see that there are actually some subtle burrs. Once cooled, you can feel it with your hands.

What does this mean?

This indicates that the power of the laser beam is no longer sufficient.

There are glitches. is cutting fast enough. It's like a tug-of-war. There will be burrs.

Replace the 300 mm steel plate.

"Whew!"

"Whew!"

The laser beam is shot out again.

The thick steel plate was also successfully cut.

However, after cooling, a higher number of burrs can be found. It's also more obvious. It can be seen with the naked eye.

Replace the 500 mm steel plate.

"Whew!"

"Whew!"

The laser beam is ejected.

The thick steel plate was successfully cut.

It wasn't cut in an instant, though. There is a slight pause in between.

This fully shows that the laser beam is already the end of the strong crossbow. It is not able to cut through a 500 mm thick steel plate in an instant.

As for the burrs or something, it's even more obvious. There is also a slight misalignment of the incisions.

The steel plate itself is gravity-sensitive. Displacements occur.

The cutting speed is not fast enough, and once the steel plate is displaced, the cut cannot be kept flat.

Continue testing.

Replace the 750 mm thick ordinary steel plate.

This time, the stagnation was even longer.

It shows that the energy of the laser beam is already seriously insufficient. It's too much to do.

What to do?

Reduce the beam diameter.

Sure enough, after the beam was reduced, the cutting power did increase.

However, the smaller the beam, the less destructive.

Of course, the specific operation depends on the actual use environment. What if a miracle happens?

In fact, Wang Bu'an is really not interested in laser cannons.

The main thing is that the current power is not enough. Reluctant to use it, I feel that I am also subject to many constraints.

It's better to wait for the power to be strong enough in the future, and it's not too late to study it.

Suggestion?

Of course there is.

After all, he has level 100 scientific and technological knowledge!

Quickly take out a large USB flash drive.

There are a total of 30g of data in it. It's all about laser cannons.

As for those that can be used and those that are not, it depends on the analysis of the relevant technicians themselves.

Now, he should hurry up and go to Xinye Heavy Machinery to find Wang Buan.

It feels like the Apocalypse Tank is not very useful.

But laser cannons are even less useful.

Go to the airport.

On the Bull Demon King Transport Plane.

Direct flight to Shinno Heavy Machinery.

Landing.

Zhonghui has been waiting for a long time.

He looked very excited.

"Chief Engineer Wang. Look!"

"Good Fellow......"

Wang Buan couldn't help but praise.

It's a veritable behemoth. A 180-ton Apocalypse tank.

Four wide tracks, two 140-mm tank guns, a dense pack of "Hedgehog" anti-aircraft missiles, and eight auto-sensing machine guns.

Is this a tank?

No.

This is a mobile battle fortress.

Each tank gun was prepared with 250 rounds of shells. A total of 500 rounds. There are various types of ammunition. Use an automatic loader.

A total of sixteen "Hedgehog" anti-aircraft missiles.

The caliber of the machine gun is 12.7 mm. The ammunition reserve is 15,500 rounds each.

If you want to say what is the biggest feature of the Apocalypse tank, it is leniency. The space inside is also very large, and you can carry a lot of ammunition.

Wherever you go. It was a semi-stationary turret. Against the enemy's lightly armored units, or infantry, will play a devastating advantage.

Still, so far there are no clear orders for Apocalypse tanks. All the bigwigs of the Army Rabbit are pretending to be deaf and dumb.

Wang Buan is not in a hurry. It doesn't matter if you don't have a buyer. He didn't expect this to get rich either.

This is a technical reserve. Maybe you'll use it sometimes.

comforted Zhong Hui a few words, and quickly returned to Zhancheng Port.

This time, he was called back by Pang Xihua.

It's time to start endorsing again.

Endorse what?

A brand new model of warship.

Class 072 landing ship.

Secret model, not yet disclosed.

Including the design drawings, they have just been completed.

After Pang Xihua got the drawings, he first came to Wang Buan. Ask him to look at it and check it.

The implication is, of course, to ask Wang Bu'an to endorse it.

The unspoken rule now is that the success rate of approval of R&D projects signed by Wang Buan is very high.

If Wang Buan refuses to sign, it will be difficult to approve it.

Sheng Huainan's nuclear submarine is a typical example.

If it had Wang Buan's signature, it would have been approved a long time ago.

However, Wang Buan just didn't sign it. As a result, it has been delayed until now, and it has been tried to be carried out.

The design displacement of the 072-class landing ship is 28500 tons. The design maximum speed is 45 knots.

Front and rear helicopter platforms. It can carry 4 helicopters. Including Tyrannosaurus Rex and Stegosaurus helicopters.

It is possible to carry the equipment of an infantry battalion. Including tanks, armored vehicles, artillery, and all other personnel and supplies. The sustained capacity at sea is 30 days.

Why is the ability to sustain so short?

Because it's loaded with a full infantry battalion!

A fully stocked infantry battalion. Almost seven hundred. Plus armament. That's not a small amount.

The landing ship itself also has several hundred people. Plus infantry battalions. More than 1,000 people.

The eating, drinking, and Lazar of so many people is definitely not a joke.

We have to store hundreds of tons of rice alone.

And flour, vegetables, fruits, etc., all big numbers.

Even, in case of need, a full infantry regiment may be crammed. More than 2,000 people.

I feel that the displacement of 28,500 tons is not enough.
