From University Lecturer to Chief Academician

The research team never imagined that they could obtain detailed data on the excitation effect of the gravitational shield through satellites passing above.

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

It is difficult to obtain accurate data with this experimental method.

One reason is that the target ball will be erratic due to the influence of wind, and air resistance will have a great impact on subsequent calculations, so the calculation results will be inaccurate. Only a dozen target ball data can be used to obtain a closer result.

The second is the impact of the gravity shield release range.

The range of the gravity shield released is too large, including the central range and the range of influence, forming a hemisphere with a radius of about four kilometers.

In addition, the distance control of the gravity shield release is not precise. There may be a slight difference, and the release range will deviate by several kilometers.

The research team is worried that the gravitational shield will affect the ground, which may cause great damage or even cause a huge accident. Then they can only make the light pressure engine fly higher and let the gravitational shield gradually approach the target from top to bottom. ball.

If the experiment is carried out in this way, the first contact with the ball will be at the edge of the gravity shield, which may cause the ball to escape the range of the gravity shield.

Then the light pressure engine can only perform tracking experiments, and the situation will become a bit embarrassing.

Of course, the research team also wants to test the impact of gravitational shields on satellites. The problem is that the temperature at an altitude of 100 to 150 kilometers can directly be classified as a special spy satellite. They have no available Test fit for purpose.

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

As for low-altitude satellites specially launched for testing, they also need to communicate with the military department, which means that the military department is directly involved in the test, and it will also attract the attention of other national agencies, or even conduct special monitoring, which may expose the Gravity shield technology seems to be a bit worth the loss.

All in all, the passing satellite was a surprise.

The first-order radar made an accurate measurement and tracked it for about a minute. All the data was in front of them. Even the subsequent trajectory could be calculated very clearly. They obtained accurate data and could even calculate the satellite. The approximate range of the fall.

But data from satellites alone is not enough.

This is mainly because the intensity of the gravity shield coverage gradually decreases from the center point outwards. The satellite does not pass through the center area, but only appears in an almost straight line on the periphery.

The data measured by the radar is very accurate, but it only obtains part of the data. For example, the average gravity intensity is 1.941 times the earth's gravity, and the release distance is about 81 kilometers.

"Judging from the data obtained by the satellite, the coverage of the gravitational field is a hemisphere with a diameter of 8.3 kilometers."

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

Wang Hao made a brief summary, "According to the calculated gravitational field strength, release distance, and coverage, if the light pressure engine flight path is used as the center line and two gravitational fields are released at an angle of 120 degrees, It’s enough to ensure the safety of the money-earning party.”

Others followed up and said, "The range is indeed very large, the distance is also very far, and the intensity is high enough. It is enough for the current stage."

"Unless something huge with a radius of more than one kilometer and heavy enough appears on the front, it will not pose a threat."

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

"The main danger is those very small things, for example, some very small satellite fragments or floating pebbles. In space, this kind of thing is the most dangerous."

"That's true..."

While everyone was discussing, the light pressure engine was already hovering at an altitude of 86 kilometers.

The experiment on the gravity shield continues.

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

After the gravity shield is released, the distance is still out of reach of the target ball. 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 onto the positions of more than a dozen target balls. Using the function of the small excitation propulsion nozzle, the light pressure engine can fly freely in any direction at high altitudes, and the direction control is still very flexible.

When the gravity shield release range approaches the target ball, it is obvious that the target ball begins to move laterally. All target balls show the same movement pattern, as if they were suddenly blown by a strong wind.

The light pressure engine has been tracking the position of the target ball and controlling the center area of ​​the gravity shield to approach the target ball, but in the end six of them left the area, and the rest were covered by the center area normally.

This process took over an hour.

The whole process is not only testing the gravity shield, but also testing the electronic system, regulation performance and flight control performance of the light pressure engine, etc.

The research team also obtained a series of data.

After the gravity shield test was completed, the light pressure engine executed the order to return to the base, and the testers also performed descent control during the process.

The control room then took over operations and returned the light pressure engine to base.

While the light pressure engine was still in the process of returning, cheers rang out in the control room. They were not worried about the engine returning to the base because takeoff and landing tests had 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 gravity shield is really great. Just looking at the effect on satellites, you know that the gravity shield is a major security guarantee.

"In space, the most feared thing is physical collision. Now the problem has been solved. With the gravitational shield, we no longer have to worry about the light pressure engine colliding with something in space."

"Whether it's a meteorite or a satellite fragment, don't worry."

Everyone is excited.

They are very aware of the significance of the gravity shield. With the gravity shield, they can directly combat physical dangers in space, and they can also directly combat weapons threats on the ground.

This means so much.

In fact, the research team originally thought about the physical dangers in space and the weapons threats on the ground, but the key is that they have no way to do this.

The light pressure engine is too big.

No matter how flexible and powerful it is, it can't do anything to satellite fragments and meteorites due to its size.

Same goes for ground threats.

The light pressure engine is too big. If it is at an altitude of tens of kilometers and launches too many missiles on the ground, it will be very difficult to escape in 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 speaking, it is already a great thing that a large spacecraft can have defense and active attack means.

If you encounter tiny space debris at high speed, you will almost have to admit that you are out of luck. And the light pressure engine is too big, so the risk of similar threats is even greater.

Now, neither threats in space nor threats on the ground can directly threaten the light pressure engine. Its own safety has been greatly improved. At the same time, it also has another active attack method that can directly make people in space satellite deviated from its orbit.

Thinking of this, everyone was very excited.

…

Amrican, Hexagon, Data Room.

Officials and consultants watched the entire test of the light pressure engine. They did not realize that the orbit deviation of the low-altitude satellite was related to the light pressure engine, but continued to discuss the performance and threats of the light pressure engine.

"The light pressure engine, or the large spacecraft made with it, poses too great a threat to us."

"If the research is successful, they will have unlimited space fortresses and space weapons that can threaten all satellites."

"Although I haven't seen any laser weapon tests, if it's in space, I believe their laser weapons can threaten any target within a thousand kilometers."

"It's very scary."

"If they want to land a satellite, all they need is a range close to a thousand kilometers."

The data room became quiet.

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

Now we are considering space weapons, and the most high-end space attack capabilities they possess are satellite tracking capabilities. By tracking satellites in space, they can calculate precise trajectories, and then launch missiles on the ground to attack.

The second method is to adjust the orbit of the satellite to directly collide with the tracked satellite.

They have launched more than a dozen military satellites for space monitoring and orbit correction.

In the past, they thought that the technology they mastered was already very high-end.

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

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

The space weapon technology they master is like ordinary swords, guns and clubs, and it requires manpower to fight directly, while the technology mastered by the opponent is like a submachine gun with unlimited bullets.

How does this compare?

The gap between the two can no longer be calculated based on reason.

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

Everyone in the data room felt helpless. They could not think of a direct response. The only way was to use missiles on the ground to carry out saturation coverage attacks in low-altitude areas. The premise was that the opponent's spacecraft flew out of the country, or even flew directly to it. Above their military area, otherwise the distance would be too far.

"Alas~~"

Many people couldn't help but sigh.

Amrican held a high-level meeting the next day. Three decisions were made at the meeting. One was to restart the f-ray experiment and let the Groom Lake project team and the military cooperate in research.

The second is to increase the production of large quantities of medium and long-range missiles.

The last step is to invest in the research and development of space weapon technology. The direct requirement is to develop a ‘military satellite with the capability of emitting laser weapons’.

Even if a satellite can only fire one laser weapon, it may be able to have a very good effect and at least have a certain deterrence capability.

Of course, research and development is still very difficult.

This is not just about sending laser weapons into space.

First of all, energy must be supported by large-capacity batteries, because batteries have a long life and the power will be greatly reduced if not used for a long time.

The second prerequisite for being able to launch laser weapons is to be able to lock the target, then 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 problems in various aspects.

After hearing the research requirements, many experts in the military field felt that the senior officials were dreaming.

Some people even joked, "Maybe we should develop a nuclear-powered satellite and let a super-large rocket send it into space..."

…

The gravity shield test was very successful.

The satellites passing above the light pressure engine provided very precise data, and 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 is very satisfied with the performance of the gravity shield and can start manufacturing it in the next step.

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

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

"In addition, the gravitational field in the cabin needs to continue to be improved. We discovered new problems during the test. For example, when the acceleration of the light pressure engine changes rapidly, the gravitational field adjustment cannot keep up."

“This part continues.”

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

That last part was just brought up in the meeting.

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

Zhou Changyuan said awkwardly, "...It's already under construction."

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

"This, this... I'm not sure either, Academician Wang, Director Chen is responsible for this part of the work." Zhou Changyuan became even more embarrassed.

"I'll ask myself."

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

The main research and development work of the Spacecraft Industry Company is still placed on the light pressure engine and space carrier, while the small spacecraft is left to the space agency.

They can't do all the work.

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 result was very unsatisfactory.

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

Their anti-gravity spacecraft research plan started almost at 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 gravity shields. The space agency has not even assembled the first prototype of the anti-gravity spacecraft?

"What on earth are they doing!"

"This is too slow!"

"Does it all take time? With this kind of work efficiency, it seems that we need to consider whether to cooperate with them on small spacecraft..."

Wang Hao kept shaking his head depressedly.
