I have a little black hole

It's not an exaggeration for Kuafu to say this. At the speed of these two detections, if it is out of Lei Tiantang's control, it can really cause a lot of harm.

You know, the two detectors are surrounded by a thick multi-layer protective layer, so the overall strength of the detector is very strong. If such a strong object is hit at such a high speed, you can know the danger. No wonder he wants to remind his boss in particular.

"Got it! I will be careful, but your worries are superfluous! As long as it is within the scope of my source, there will never be any danger you say. Just test yours!" Lei Tiantang is confident. Said.

If he had just acquired the ability, he might have problems because of insufficient proficiency in control, but now that time has passed for more than three years, after such a long period of exercise, the control of the field has been tempered into an instinct. , So Kuafu’s worry was unnecessary in his opinion.

Even if it is changed at such a high speed, it will definitely not be a problem, because the two detectors can only move at such a high speed under his control.

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

The process of autonomously changing the orbit of a satellite during its orbit is called orbit change, and launching various satellites and probes into earth orbit or other solar system orbits requires orbit change operations.

The satellite orbit is elliptical, and the method of saving rocket fuel can be launched into a large elliptical orbit. When the satellite is in a distant location, the attitude of the satellite adjusts the rocket to ignite, so that the satellite's orbit becomes the required height.

The orbit can be changed multiple times, which requires accurate calculation of the time for the satellite to orbit, controlled by the ground command.Affected by the gravity of the earth, the orbit of man-made satellites and spacecraft (including the space station) will drop at a speed of about 100 meters per day.

Such a drop in altitude will affect the normal operation of artificial satellites and spacecraft (including space stations), so they often need to change orbit during the course of orbit.

In addition to avoiding the damage caused by "space junk", the orbit change is mainly to ensure the life of its operation, and these are also equally important for the detectors that Lei Tiantang now tests.

In the future, most of these probes will also enter the galaxy system on the side of the small black hole. Long-term detection tasks.

This requires that the orbit changing function of these detectors will definitely not be a problem, and the requirements for the orbit changing function of these detectors can be much higher than those of satellites and other detectors launched from Earth to Earth orbit.

After all, the environment of the star system over there is still unknown, and the conditions of the planets and asteroids to be detected are unknown. If you want to enter their orbit according to the detection mission, you will of course require more changes in the detector’s orbit. high!

In addition, all kinds of artificial garbage in the Earth's orbit and various small celestial debris, etc. can cause damage to the satellite and other detectors. Humans are mastered after a long time of detection and recording, so the satellite will advance before being hit. Deflect to avoid being crashed.

Lei Tiantang is about to throw these detectors over the little black hole without this treatment. Although each detector is equipped with high-power detection equipment, even during the high-speed movement, even those space debris are detected. The reaction time left for the detector is also very short.

Therefore, of course, the requirements of the detector's orbit change function will be higher, otherwise Lei Tiantang can throw the detector over there once in a while!

"That's good! The transition test begins!

The main thruster ignites!...

Auxiliary thruster ignition!...

The spare thruster ignited..." With the reminder of Kuafu in the headset, the two detectors that are moving at high speed have started various orbit changing operations.

In order to ensure that the orbit changing function of all detectors can meet the requirements of complex tasks, the orbit changing thrusters of these detectors have two sets of systems. One set is a system composed of main thrusters and auxiliary thrusters. This system It is an ion thruster system. They are both the acceleration system of the satellite and their orbit changing system.

Ion thrusters, also known as ion engines, are a type of space electric propulsion technology. They are characterized by low thrust and high specific impulse. They are widely used in space propulsion, such as spacecraft attitude control, position maintenance, orbit maneuvering, and interstellar flight. .

The principle is to ionize the gaseous working fluid first, and expel the ions accelerated under the action of a strong electric field, and push the satellite to adjust the attitude or orbit transfer tasks through the reaction force.The ion thruster has the characteristics of high specific impact, high efficiency and low thrust.

Compared with the traditional chemical propulsion method, the ion thruster requires less working mass, which is the most practical propulsion technology suitable for long-distance navigation. This feature is used by Kuafu and the deep space laboratory as the main The reason for the thruster system.

However, this propulsion system is not without its shortcomings. The main disadvantage is of course 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 accelerate the detector non-stop for a long time, and it needs little fuel to carry. It can also react in advance to carry out the orbit change operation under preparation.

However, its shortcoming is that it has insufficient instantaneous reaction ability. What is the situation in the cosmic environment over the small black hole and the stellar system in the mission area? It is not yet known, but it must be very complicated. Under such a complicated cosmic environment, various accidents May appear at any time.

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

Therefore, these detectors are also equipped with a set of propulsion systems that use chemical fuel as fuel. The high explosiveness of the chemical fuel propulsion system can make these detectors more calm when faced with these emergencies, allowing detection The service life of the device can be extended.

After all, cosmic exploration requires long-term detection to obtain richer data. If a detector is launched, it will be scrapped after a few days of work. How much useful data can be obtained?

In particular, Lei Tiantang also hopes that the space telescopes in these 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 position can be compared with the stars detected on Earth. The picture can be closed!
