Chapter 1261 Compensation?
"You may not know that the orbital resources in the outer space of the Blue Planet are now scarce resources. Because the orbits are fixed routes, when there are more spacecraft and satellites on the same orbit, this orbit cannot continue to enter new spacecraft and satellites, preventing dangerous events such as congestion and collision of spacecraft in the orbit.
After installing the attitude engine, our spacecraft will not deviate from the orbit. Even if there is an error, it can be quickly corrected back to the orbit."
During the explanation of Chief Engineer Li Jian, the director also released the orbital diagram of the Kyushu spacecraft at the right time. It was like a hula hoop route around the Blue Planet. A dog-head-shaped mark was slowly moving on the orbital line, and below it was the Blue Planet.
"There are many types of attitude control engines for spacecraft and satellites, but they all work in three ways.
The most basic technology is cold gas propulsion. Spacecraft are equipped with gas cylinders filled with inert gas, and attitude control is achieved through the reaction force generated by the accelerated ejection of gas expansion. The initial technical difficulty is low and the cost is low, but the controllability is poor and the thrust is small. Of course, this technology currently also has advanced systems, that is, the micro-newton-level variable thrust cold gas propulsion system, which can enable satellites to achieve an 'ultra-quiet and ultra-stable' state and detect gravitational waves.
The second type is the most common and widely used chemical energy working fluid propulsion device, which you can use It is understood that a small rocket, whether it is a scientific research satellite in the last century or today's commercial meteorological, communication and commercial satellites, all use the attitude engine of this propulsion device.
The third type of ion propulsion is to heat and ionize the liquid fuel first, and then use electromagnetic coils to accelerate the ions to spray out to form thrust. The specific impulse of this propulsion system is very excellent and can easily reach more than ten times that of other ordinary fuels. For example, NASA's newly developed xenon ion thruster and the GOCE satellite known as the "Ferrari of Space" both use this technology.
However, this technology requires a high threshold, and although the specific impulse is excellent, it is limited by the unit power. The thrust generated is only tens of millinewtons. Relying on this system, if the spacecraft wants to change its orbit, it will take months, so it can only be used as a power system for attitude control. It can be fine-tuned but cannot change its course at will.
Although our Tiangong Space Station in Daxia also uses ion thrusters to control the attitude of spacecraft, the Tiangong Space Station uses more advanced Hall thrusters, which have much greater thrust than ordinary ion thrusters, so it can control the Tiangong Space Station to take emergency shelter in a short time.
With the continuous advancement of aerospace projects, our Jiuzhou Technology is also in the field of propulsion systems. Moving forward, we are not only developing traditional chemical energy working fluid propulsion devices and cold air propulsion, but also developing electric and ion propulsion systems.
Of course, due to the rapid progress of our company in the field of materials, solid-state energy batteries have enabled our electric propulsion system to develop rapidly. After being equipped with flexible folding solar wing panels, our solid-state energy combined with the "infinite array propulsion engine" can achieve a relatively objective output of propulsion force in a short period of time and adjust the orbit of the spacecraft. "
With Li Jian's popular science, the popularity of Jiuzhou Aviation's live broadcast room has rebounded, but the new round of barrage craze was caused by a phenomenon.
Some viewers found that on the orbit of Jiuzhou Technology's spacecraft, there were suddenly three flashing light spots that were moving in the opposite direction of the spacecraft. According to the schematic diagram of the live broadcast room, these three light spots will hit the spacecraft soon.
Some viewers hurriedly launched a barrage.
"Fuck? Boss, stop lecturing. Look at the uninvited guest on the screen!"
"Ergou is still sleeping. Can he wake up and drive the aircraft?"
"Did anyone notice the three small red dots on the screen? There was nothing like this just now. Did I see it wrong?"
"As we all know, the red dots are target signals. If this is in the game, it is probably the point where the boss is pointing."
Seeing these dense bullet screens, the expression of Chief Engineer Li Jian in the live broadcast screen also became serious at the same time.
Although there was a delay of several minutes, when the live broadcast audience and the technicians saw the same special situation, they all had their most intuitive expressions.
At Li Jian's request, the director did not cut off the subsequent command dialogue, but only muted the technical parameters of some key instructions.
So, netizens in the live broadcast room saw the real version of "news live broadcast".
In the live broadcast room, Li Jian, the chief engineer of the aerospace project of Jiuzhou Technology, who was originally giving a lecture, said in a steady voice: "This is SpaceX's Starlink satellite. How could it suddenly switch to the orbital height of our spacecraft? Report the situation to SpaceX urgently, declare that we have been allowed to use this orbit before, and that this orbit is not the working orbit of these three satellites, and let SpaceX guide the satellite to avoid our spacecraft.
Prepare to start the attitude adjustment engine and perform orbital migration."
In the voice-over, the netizens in the live broadcast room heard the orderly arrangement of the chief engineer, and they felt much more at ease.
But no matter how at ease they were, they were still a little speechless about the unruly SpaceX Starlink satellite.
Not long after, netizens heard the voice of a staff member of Jiuzhou Technology.
"Space Exploration Technology Company SpaceX said that Starlink had a minor fault and is currently investigating the source of the fault. It is expected to update the system patch in three hours.
At the same time, their engineers gave a prediction that it might be due to the geomagnetic storm caused by the solar flare activity some time ago. The magnetic field of the blue planet blocked the energy of the solar storm in the upper atmosphere and heated it, causing the atmosphere to expand and become denser, damaging some communication electronic equipment.
Regarding the three out-of-control satellites, they said that they are currently unable to control the three satellites. If the three satellites cause damage to our spacecraft, they expressed concern and apologies, and will let the insurance cover part of the loss.
Under our questioning, they informed us that the insurance amount will be compensated for one million US dollars. ”
One million US dollars?
Hearing this number, let alone the staff and engineers, the netizens of the blue planet were all angry and laughed.
"One million US dollars? SpaceX sends beggars? Jiuzhou Technology lacks this little money?"
"It's so funny. Mr. Gu wakes up every day and there is so much money in the company account that he can't count it. What's the use of one million US dollars?"
"Jiuzhou Technology probably spent hundreds of millions of dollars to develop and manufacture this equipment. I wonder if Jiuzhou Technology has bought insurance for the spacecraft."
"Buy insurance for the experimental spacecraft? If you are an insurance company and you dare to start this business today, you will go bankrupt tomorrow. Do you believe it?"
