I Have a Little Black Hole

It is no exaggeration for Kuafu to say this. With the current speed of the two detections, if they are out of Lei Tiantang's control, it can really cause a lot of harm.

You know, these two detectors are surrounded by a thick multi-layer protective layer, so the overall strength of the detectors is very strong. If such a strong thing is knocked out at such a high speed, you can know the danger if you think about it. No wonder he had to remind his boss in particular.

Understood! I will be careful, but your worries are unnecessary! As long as it is within the scope of my source, there will never be any danger you said, you can test yours! Lei Tiantang confidently said.

If he had just acquired the ability, he might have problems due to insufficient proficiency in control, but now it has been more than three years, and after such a long period of training, the control of the field has been tempered into an instinct. , so Kuafu's worry is unnecessary in his opinion.

Even if it is moving at such a high speed, there will never be a problem, because the two detectors themselves can move at such a high speed under his control.

Of course, he is well aware of the importance of the detector's ability to change orbits, so he also attaches great importance to this test.

The process of autonomously changing the operating orbit of a satellite during its orbit is called orbit change. Orbit change operations are required to launch various satellites and probes into Earth orbit or other solar system orbits.

The orbit of the satellite is elliptical. The method of saving the fuel of the rocket can be launched to a large elliptical orbit first. When the satellite is at the apogee, the attitude of the satellite is adjusted to ignite the rocket, so that the orbit of the satellite becomes the required altitude.

The orbit change can be repeated many times, which requires accurate calculation of the time of the satellite orbit change, which is controlled by ground commands. Affected by the earth's gravity, the orbits of artificial satellites, spacecraft, including space stations, will drop at a speed of about 100 meters per day.

Such a drop in altitude will affect the normal operation of artificial satellites, spacecraft, including space stations, so in the process of orbital operation, they often need to change orbits.

In addition to avoiding the damage of space junk, the orbit change is mainly to ensure its operating life, and these are equally important to the detectors Lei Tiantang and the others are currently testing.

In the future, most of these probes will also enter the star system on the side of the small black hole, and many probes will also enter the orbits of the planets or asteroids in the star system in order to conduct experiments on them. long-term exploration missions.

This requires that the orbit change function of these detectors will never go wrong.

Moreover, the orbital change function requirements for these probes can be much higher than those of probes such as satellites launched from the earth to the earth's orbit.

After all, I still don’t know what the environment of the star system over there is, and I don’t know the situation of the planets and asteroids to be detected. If you want to enter their orbits according to the detection mission, of course, the ability of the detectors to change orbits will be required. high!

In addition, all kinds of artificial garbage and various small celestial debris in the earth's orbit can cause damage to satellites and other detectors. Humans have mastered it after a long period of detection and recording, so the satellite will be in advance before being hit. Change tracks to avoid being crashed.

The detectors that Lei Tiantang was going to throw to the small black hole would not have this treatment. Although each detector is equipped with high-power detection equipment, even if the space junk is detected during the high-speed movement , the reaction time left for the detector is also very short.

Therefore, the requirements for the detector's orbit changing function are of course higher, otherwise Lei Tiantang can throw the detector over there every once in a while!

That's good! The track change test begins!

The main thruster fires!

Auxiliary thrusters fire!

Backup thruster ignition With Kuafu's reminder in the headset, the two probes that were moving at high speed began various orbit changes.

In order to ensure that the orbit change function of all the probes can meet the complex mission requirements, the orbit change thrusters of these probes have two sets of systems, one is a system composed of main thrusters and auxiliary thrusters. It is the ion thruster system, which is the acceleration system of the satellites and their orbital change system.

Ion thruster, also known as ion engine, is a kind of space electric propulsion technology, which is characterized by small thrust and high specific impulse, and is widely used in space propulsion, such as spacecraft attitude control, position maintenance, orbital maneuvering and interstellar flight, etc. .

The principle is to first ionize the gaseous working medium, and then accelerate the ejection of the ions under the action of a strong electric field, and push the satellite to perform attitude adjustment or orbit transfer tasks through the reaction force. The ion thruster has the characteristics of high specific impulse, high efficiency and small thrust.

Compared with the traditional chemical propulsion method, the ion thruster requires a small mass of working medium, and is the most suitable for long-distance navigation among the practical propulsion technologies. This feature is that Kuafu and the Deep Space Laboratory regard it as the main The reason for the thruster system.

However, this propulsion system is not without shortcomings. The main disadvantage is of course that their thrust is not high. Even if the most advanced ion thrusters are used in the Deep Space Laboratory, their thrust is not high.

The advantage of such a propulsion system is that it can continuously accelerate the probe for a long time, and it needs to carry very little fuel, and it can also react in advance to perform orbit change operations when prepared.

However, its disadvantage is that its instantaneous response ability is not enough. What is happening in the cosmic environment over the small black hole and the star system in the mission area is still unknown, but it must be very complicated. Under such a complex cosmic environment, various accidents may appear at any time.

Faced with such a situation, these probes must have a backup thruster system to deal with these possible situations.

Therefore, these detectors are also equipped with a chemical fuel-fueled propulsion system. Using the high explosiveness of the chemical fuel propulsion system, these detectors can be more calm in the face of these emergencies, allowing the detection of The service life of the device can be extended.

After all, cosmic detection requires long-term detection to obtain richer data. If a detector is launched and then scrapped after working for a few days, how much useful data can be obtained?

In particular, Lei Tiantang also expects that the space telescopes in this batch of detectors can detect the situation of the star field where the small black hole is located, and then use the star map to compare whether its location can be compared with the stars detected on the earth. The pictures can be overlapped!
