When it came to the issue of laser weapons, Teacher Xu and Teacher Zhao became very interested, especially Teacher Zhao. He is a leader at the military level and is naturally very interested in various weapons.

Teacher Xu knows more than Teacher Zhao because when he was doing research, he submitted a report on laser research.

He asked, "I know this research should be conducted around annihilation particles, right? How far are you at?"

Wang Hao nodded and said, "Professor Tang Hongchao's team is responsible for this project. Last month, they used annihilation particle equipment to create a strong laser. We have done intensity testing and found that the ground can hit incoming targets.

The furthest effective strike distance exceeds two hundred kilometers."

"Theoretically, in the universe, the effective coverage distance will exceed 10,000 kilometers, and at an altitude of more than 100 kilometers, the effective distance will be within the range of 3,000 to 5,000 kilometers."

"This is mainly affected by air density."

Air density and dust have a great impact on laser weapons. They can absorb laser energy, thereby greatly reducing the effective distance.

Even at an altitude of more than 100 kilometers, there is still thin air, which will also affect the laser strike range.

Wang Hao frowned as he spoke. He was still a little dissatisfied with the power of the laser.

Teacher Zhao doesn’t see it that way.

He still knows about laser weapon technology. The military has corresponding laser weapons, but they can generally only be used to attack drones near the ground. The effective range is 20 kilometers, which is great.

The laser technology currently developed around annihilation particle equipment can increase the effective strike distance by more than ten times, which can be described as 'incredible'.

Laser strikes the target at the speed of light. No matter what target it is, as long as it is locked, there is no possibility of escaping.

If the coverage distance can reach two hundred kilometers, theoretically speaking, any missile will not pose a threat. If it is locked at an altitude of tens or hundreds of kilometers, it will be detonated instantly.

Teacher Zhao opened his mouth in surprise. Looking at Wang Hao's dissatisfied look, he felt that Wang Hao had deliberately put on this expression.

How do you say a word?

Versailles!

"This is so Versailles! Such a powerful weapon can replace most of the anti-aircraft equipment..."

Wang Hao shook his head silently, he was indeed a little dissatisfied.

On the one hand, they are dissatisfied with the power of laser weapons, or dissatisfied with the technical capabilities. Because of the research of Tang Hongchao's team, the technology has not made any progress. The main improvements are the material strength and the strong light source environment inside the concave reflector. Both of them are different from pure lasers.

Technology doesn't matter.

There is no good way to do this.

To put it bluntly, laser weapons are condensed beams, which are very similar to the principle of creating light pressure. This is the power of pure beam production. What limits its power is the material.

If there are suitable materials that can withstand extremely high temperatures and have very high strength, then the power of laser weapons will be greatly enhanced.

However, it is too difficult to break through materials. They have already used pure first-level materials and cannot improve them in a short time.

Another dissatisfaction is the lack of power of laser weapons.

Laser weapons cannot create large-scale explosions. They are aimed at a specific target and cannot affect other targets.

After the space carrier is equipped with laser weapons, the defense system still has huge loopholes.

For example, when encountering meteorite particles that hit a large area, or dense satellite debris, the protective power of laser weapons is still too poor.

When there are tens of thousands of strike targets, the effect of more than a hundred strike ports is not obvious. However, in space and the universe, including satellites and meteorites, the speed can easily reach several kilometers per second, and some will be even faster.

If it's faster, it's faster if you include the relative speed.

When encountering a large range of meteorite particles and satellite fragments, the space carrier's protective capabilities will be severely challenged.

After Wang Hao made some explanations, he said helplessly, "So even with laser weapons, light pressure engines, including future aerospace carriers, there is still a big lack of protection capabilities!"

He shook his head helplessly.

The three teachers were speechless. They felt that laser weapons were perfect enough, so what else could they pursue?

If you encounter a large range of meteorite particles, there is nothing you can do about it. Just like there are many natural disasters on the earth, humans are simply unable to fight against them.

If it were a large-scale satellite debris, the possibility of man-made damage would be higher.

All in all, it's perfect.

…

The next day, Spacecraft Industries held a new press conference for the light pressure engine test.

This is a confirmed press conference.

If any major problems occur during the testing process, the press conference will naturally be postponed as appropriate. Needless to say, the test is successful and it will be held right now.

Many people attended the press conference.

Most of them are the management of the Spacecraft Industry Company. They talk about the current research and development work and future prospects. Their words are like pie-painting, which makes people feel a bit false. The most important thing is that they have little influence. To put it more bluntly,

, not many people believed what he said.

So when they talked about space carriers, interstellar exploration, etc., not many people cared at all, and they only recorded them symbolically.

Reporters are waiting for Wang Hao to be interviewed.

Only two people from the light pressure engine project team attended the press conference, one was Zhu Qiqiang and the other was Wang Hao.

Zhu Qiqiang has a very military demeanor. He talks about a wide range of topics and his words are sonorous and powerful. He constantly expresses his confidence in the future.

However, there is no real content at all.

The next one is Wang Hao.

Wang Hao was sitting in the center. When he picked up the microphone, many cameras quickly pointed at him.

soon.

Almost all the camera equipment was pointed at Wang Hao, which made Zhu Qiqiang who was talking a little embarrassed, because he knew that what he said would not be cared about at all, so he simply ended it briefly.

When the scene became quiet, Wang Hao said, "This time we conducted a high-altitude test of the light pressure engine. The entire test process was successful and smooth. Everyone was very happy."

"Our next work focus will be on space testing, and we will also start the design, development and pre-manufacturing of the space carrier."

"We are very confident about the follow-up work!"

He just said a few words briefly, but the media reporters in the audience were very serious, and their different attitudes made others feel very depressed, because Wang Hao did not say anything new, and what he said had even been reported by others.

I've said it before, but when it comes from Wang Hao's mouth, it gives people a completely different feeling.

After Wang Hao gave a brief introduction, he found that he had nothing to say because many others had already said it.

He simply jumped directly to the interview session.

The media reporters finally waited for the interview session. A reporter from Eagle Country directly asked about the parameters of the light pressure engine, "We saw the entire test process. The light pressure engine with a diameter of 120 meters is very huge, but we saw that it is very large."

It quickly flew to a high altitude. So Professor Wang, can you tell me what the maximum load capacity of the engine is?"

After this question was raised, many people thought that Wang Hao would not answer.

Even if the light pressure engine is developed normally, some key parameters will not be disclosed.

However, Wang Hao didn't care at all. He said directly, "We have indeed not disclosed the parameters of the light pressure engine. Some of the content involves confidentiality technology, but the question you just asked does not matter."

"I can clearly say that the maximum load capacity of the light pressure engine we have manufactured now is about 100,000 tons."

100,000 tons is the theoretical maximum carrying capacity.

If the engine power intensity reaches a certain value and the internal temperature of the concave reflector is above 7,000 degrees, it can propel a weight of 100,000 tons into the air.

When the internal temperature of the concave reflector increases, the power of the engine will also increase exponentially. There are two factors that limit the engine capacity. One is the size of the engine.

The size of the engine is actually the size of the concave reflector. When the concave reflector is large enough, the energy it can carry inside will naturally be higher at the same temperature.

The other is the width of the nozzle of the excitation propulsion device.

When making circular high-pressure light beams of the same intensity, 1 meter wide and 2 meters wide, the area of ​​the latter is four times that of the former, and the thrust it can provide is naturally four times that of the former.

The current limitations of light pressure engines are due to equipment capabilities, not technical limitations. From a technical perspective, there are no limitations.

When Wang Hao talked about the carrying capacity value, there was an uproar in the whole place.

The carrying capacity of 100,000 tons is very amazing.

This also means that the aerospace carrier can be built up to 100,000 tons, which is no worse than a huge aircraft carrier.

Later, some reporters asked about the space carrier. They wanted to know the progress of the space carrier design.

Wang Hao said, "We have determined the basic structure of the space carrier, which will adopt a cabin design surrounding a concave reflector, and will also introduce the latest gravitational field technology."

He just said one sentence, which caused another uproar in the audience.

The information revealed in this sentence is enough to shock the whole world, because he clearly stated that the space carrier will use gravitational field technology, which also shows that gravitational field technology can be officially applied.

Previously the gravitational field was just a new discovery.

Many reporters couldn't help but start discussing, "Listening to what Academician Wang said, could it be that gravitational field technology has matured?"

"It's impossible, right? It's so fast?"

"How come I haven't heard of this technology...but I think I have, in academic terms, right?"

"I know, this seems to have published a paper, it is the research result of the Antigravity Center, but it only discovered the gravitational field. What space... wave was used?"

"Can the newly discovered gravitational field be used? Could it be that they have already been able to create very high gravitational values?"
