The research team had no idea that they would be able to obtain detailed data on the excitation effect of the gravitational shield from satellites that swept overhead.

They have placed more than a dozen target balls at an altitude of 10,000 to 20,000 yuan, and the nearby airspace has been classified as an air traffic control area, and the floating target balls will not affect civil airliners.

It is difficult to obtain accurate data in this way of experimenting.

One is because the target ball will be affected by the wind and fluctuate, and the air resistance has a great impact on the subsequent calculation, so the calculation result will be inaccurate, and a closer result can only be obtained through more than a dozen target ball data.

The second is the effect of the gravitational shield's release range.

The range released by the gravitational shield is too large, including the central range and the area of influence, forming a hemispherical body with a radius of about four kilometers.

In addition, the distance control of the gravitational shield release is not precise, and there may be a slight difference in the release range of several kilometers.

The research team was worried that the gravitational shield would affect the ground and could cause very large damage, or even cause a huge accident, so the only way to do this was to let the light-pressure engine fly higher and let the gravitational shield gradually approach the target ball from top to bottom.

In this experiment, the first contact with the ball is the edge of the gravitational shield, which may take the ball out of the gravitational shield.

Then the light-pressure engine can only be used for tracking experiments, and the situation will become a little awkward.

Of course, the research group also wanted to test the effect of the gravitational shield on the satellite, but the problem was that the temperature at an altitude of 100 to 150 kilometers could be directly classified as a special spy satellite, and they did not have a suitable target for testing.

If you really do that, you have to communicate with the military.

As for the low-altitude satellites specially launched for testing, it is also necessary to communicate with the military department, which is equivalent to allowing the military department to directly participate in the test, and it will also make other national institutions notice, or even specifically monitor, which may expose the gravitational shield technology, which seems to be a bit more than worth the loss.

In short, the satellites passing over it were a pleasant surprise.

The first-order radar made an accurate measurement, and tracked for about a minute, all the data were in front of them, and even the subsequent trajectory could be calculated very clearly, and they got accurate data, and even calculated the approximate range of the satellite's fall.

But satellite data alone is not enough.

This is mainly due to the fact that the gravitational shield coverage gradually decreases from the center point outward, and the satellite does not pass through the central area, but only appears in a straight line on the periphery.

The radar measurement data is very accurate, but it only gives a partial part of the data, for example, the average gravitational strength is 1.941 times the earth's gravitational force, and the release distance is about 81 kilometers.

"According to the data obtained by satellites, the gravitational field covers a hemispherical body with a diameter of 8.3 kilometers."

"Based on the average of the peripheral strengths, we can infer that the intensity of the central region of the gravitational field is about 2.31 times the Earth's gravity."

Wang Hao made a small summary, "According to the calculated gravitational field strength, release distance, and coverage, if the flight path of the light pressure engine is the center line, and two gravitational fields with an angle of 120 degrees are released, it is enough to ensure the safety of the earner." ”

The others followed, "The range is indeed very large, the distance is also very far, and the intensity is high enough, which is enough at this stage." ”

"Unless something large enough to radius more than a kilometer and heavy enough appears on the front, it poses no threat."

"If there really is such a thing, the first-order radar would have detected it a long time ago and could have dodged it in advance."

"The main danger is still very small things, for example, some very small satellite debris or drifting pebbles, which are the most dangerous in space."

"That's ...... indeed"

By the time everyone was talking, the light-pressure engine was already hovering at an altitude of 86 kilometers.

The Gravitational Shield experiment continued.

The testers in the main control module manually adjusted the direction of the gravitational shield and aimed it at the target ball in the air, which was not directly below the spacecraft, but at an angle to it.

After the gravitational shield is released, the distance is not enough to reach the target ball, and the next step is to operate the light pressure engine to slowly approach the target ball.

This is also a test of the engine control system.

The radar has locked on to the position of more than a dozen target balls, and the light pressure engine can fly freely in any direction at high altitude by using the role of a small excitation propulsion nozzle, and the direction control is still very flexible.

As the gravitational shield was released close to the target, it was clear that the ball began to move sideways, and all the balls exhibited the same movement pattern, as if they had been blown by a sudden gust of wind.

The light pressure engine kept track of the target's position and kept the center of the gravitational shield close to the target, but in the end, six of them broke away from the area, and the rest were normally covered by the center.

This process takes more than an hour.

The whole process is not only to test the gravitational shield, but also to test the electronic system of the light-pressure engine, the control performance, the flight control performance, and so on.

The research team also obtained a series of data from this.

After the gravitational shield test was completed, the light-pressure engine was given the command to return to base, and the testers carried out descent control during the process.

The control room then took over and allowed the light-pressure engines to return to base.

While the light-pressure engines were still in the process of returning, cheers were already ringing in the control room, and they were not worried about the engines returning to base, because take-off and landing tests had already been carried out many times.

Everyone is very confident about the landing of the light-pressure engine.

The results of this test were satisfactory.

The effect of the gravitational shield is so good that just by looking at the effect on the satellite, you know that the gravitational shield is a major security guarantee.

"In space, the most feared thing is a physical collision, and now that the problem has been solved, with the gravitational shield, there is no longer any worry about the light pressure engine colliding with something in space."

"Don't worry about meteorites or satellite debris."

Everyone was excited.

They are well aware of the significance of gravitational shields, which can directly combat physical dangers in space, as well as weapons threats on the ground.

That's just too much.

In fact, the research team had first thought about the physical dangers of space and the threat of weapons on the ground, but the point was that they had nothing to do about it.

The bare-pressure engine is too big.

No matter how flexible and powerful it is, the impact of the block will not be able to do anything about satellite debris and meteorite swarms.

The same goes for threats on the ground.

The size of the light-pressure engine is too large, and if it is at an altitude of tens of kilometers, it is very difficult to escape if there are too many missiles launched on the ground and carry out a saturation attack on the entire area.

All they can think of is to use laser weapons to resist, but the number of laser weapons is limited after all.

Normally, it is a great thing that a large space vehicle can have defense and active offensive means.

If you encounter a tiny piece of space junk at high speed, you can almost only consider yourself unlucky, and the size of the light-pressure engine makes a similar threat even more risky.

Now whether it is a threat in space or a threat on the ground, it cannot directly threaten the light pressure engine, its own security has been greatly improved, and at the same time, it also has another active offensive means, which can directly derail satellites in space.

Everyone was very excited to think about it.

……

Ameriken, Hexagon, Data Room.

Officials and advisers watched the test of the light-pressure engine throughout the test, and they did not realize that the low-altitude satellite's orbit deviation was related to the light-pressure engine, but continued to discuss the performance and threat of the light-pressure engine.

"Light-pressure engines, or large spaceships built out of them, are too much of a threat to us."

"If the research is successful, they will have an unrestricted space fortress, a space weapon, capable of threatening all satellites."

"Although no laser weapons tests were seen, if in space, believing their laser weapons, are capable of threatening any target within a thousand kilometers."

"It's very scary."

"If they want to take down a satellite, all they need is close to a 1,000-kilometer range."

It was quiet in the data room.

Everyone feels powerless when they think about it, because the gap between the space technology of the two sides is too big.

Now they are thinking about space weapons, and the most advanced space offensive capability they have is the satellite tracking capability, through the tracking of satellites in space, they can calculate the precise trajectory, and then launch missiles on the ground to attack.

The second way is to adjust the orbit of the satellite to make a direct collision with the tracked satellite.

They have already launched more than a dozen military satellites for space monitoring and can correct orbits.

Before, they thought that the technology they had mastered was already very high-end.

Of course, they also thought about creating active offensive weapons in space, but space weapons need energy support, but the energy provided by solar panels is too weak.

If the aerospace carrier is successfully developed, the gap between the two sides in space military science and technology will lose its comparability.

The space weapon technology they master is like an ordinary knife, gun and club, and they still need manpower to fight directly, while the technology mastered by the other party is like a submachine gun with unlimited bullets.

How does this compare?

The difference between the two is no longer reasonable.

Of course, a submachine gun with infinite bullets is not invincible, but if you want to defeat such an opponent, you don't know how many lives you have to fill up.

Everyone in the data room felt very helpless, they couldn't think of a direct response, the only way was to use the missiles on the ground to carry out a saturation coverage attack in the low-altitude area, and the premise was that the opponent's spacecraft flew out of the national area, or even directly over their military area, otherwise the distance would be too far and too far.

"Ah~~"

Many people couldn't help but sigh.

The next day, American held a high-level meeting, at which three decisions were made, one was to restart the F-ray experiment and have the Lake Groom project team and the military cooperate in research.

The second is to increase the manufacture of large-scale medium- and long-range missiles.

Finally, it is to invest in the research and development of space weapon technology, and the direct requirement is to develop 'military satellites with the ability to launch laser weapons'.

Even if a satellite can only launch one laser weapon, perhaps, it can also have a very good effect, at least with a certain deterrent ability.

Of course, the difficulty of research and development is still very high.

It's not just about sending laser weapons into space.

First of all, the energy side must be supported by large-capacity batteries, because batteries have a lifespan, and long-term non-use of electricity will be greatly reduced.

Second, the premise of being able to fire laser weapons is to be able to lock onto the target, so it needs to be equipped with a radar system, and the performance of the radar system supported by solar panels is obviously very low.

At the same time, there are other aspects of the problem.

Many experts in the military field listened to the research requirements and felt that the high-level personnel were dreaming.

Some even quipped, "Perhaps, we should develop a nuclear-powered satellite and send it into space with a super-large rocket......

……

The Gravitational Shield test was very successful.

The satellites passing above the light-pressure engine provided very accurate data, and when compared with the data provided by the target ball, the research team had a very clear understanding of the strength, release distance and range of the gravitational shield.

The research team was very satisfied with the performance of the gravitational shield, and the next step was to start manufacturing.

They plan to install six gravitational shield devices on the light-pressure engine.

At the summary meeting held, Wang Hao also explained the next step, "The first is to continue to improve the surrounding cabin, to open about ten cabins, and build a perfect life cycle system to ensure that personnel can work and live in the cabin for a long time." ”

"In addition, the gravitational field in the cabin needs to be improved, and we have found new problems in the test, such as the gravitational field adjustment when the acceleration of the light-pressure engine changes rapidly."

"This part will continue."

"Finally, we need to equip the engines with a small spacecraft, and we need to build a hovering area for the small spacecraft around the capsule and above."

The last part was only mentioned at the meeting.

After the meeting, Wang Hao found Zhou Changyuan, a representative of the space agency, and asked about the research progress of the space agency's anti-gravity spacecraft.

Zhou Changyuan said embarrassedly, "...... It is already being built. ”

"Under construction? When will the first prototype be completed? ”

"This, this...... I'm not sure, Academician Wang, this part of the work is in charge of Director Chen. Zhou Changyuan was even more embarrassed.

"I'll ask myself."

Wang Hao really felt a little helpless, and they had decided to cooperate with the space agency to let the space agency develop various types of small spacecraft.

The main research and development work of the Spaceship Industry Company is still placed on the light-pressure engine and the space carrier, and the small spacecraft is handed over to the space agency.

They can't be in charge of everything.

The space agency can complete the research and development of various types of small spacecraft, and they can directly place orders for procurement in the future.

The results were unsatisfactory.

The space agency's pace of research and development is simply too slow.

Their anti-gravity spacecraft research program started at about the same time as the light-pressure engine.

The light-pressure engine is about to be tested in space, and it is even equipped with laser weapons and gravitational shields, and the space agency has not even assembled the first prototype of the anti-gravity spacecraft?

"What the hell are they doing!"

"That's too slow!"

"Doesn't it all take time? This kind of work efficiency, it seems that we have to consider whether to cooperate with them in a small spaceship......"

Wang Hao kept shaking his head depressedly.
