Super Weapon Swap System

Satellites need electricity. Different satellites use different electricity. In the early days, satellites were limited by volume, weight and technical conditions. Most of them used chemical energy batteries as their own energy systems, such as silver zinc batteries.

For example, dongfanghong-1, the first satellite launched by Han, is a typical satellite using chemical energy batteries. The silver zinc battery equipped with it has an expected working life of 20 days and an actual working time of 28 days, which is considered to have overfulfilled the task.

At the same time, due to the short service life of the battery, this power supply mode is not commonly used. Now the most commonly used is the solar cell.

Solar cells can generate electricity as long as there is sunlight, but they can only generate electricity and cannot be stored, so they also need to have a power storage meeting.

The combination of solar cells and batteries is the choice of most satellites.

Because the solar panel is greatly affected by the external environment, the power supply of the solar panel will be affected by many reasons, such as the height of the satellite orbit and the different angle of sunlight. Even the satellite itself sometimes affects or limits the use of solar panels due to mission loads, technical conditions and other factors. Therefore, even if the energy system looks very similar, the specific situation of each satellite is different.

At the same time, the layout of solar cells is also different.

Early satellites attached solar cells to the surface of satellite stars, but due to their small area, the power generation was not high. Later, most satellites pasted tens of thousands of solar panels on large panels, and then installed the whole solar panel outside the satellite, greatly improving the power generation.

However, this plate-shaped solar cell cannot be directly installed in the rocket, so it is in this state when it is launched.

Moreover, in order to make the solar panels on satellites always face the sun to obtain the maximum electric energy, many solar panels on satellites adopt some advanced technologies: first, they are equipped with a driving mechanism to rotate with the solar panels; Second, the sun sensor is used to capture the orientation of the sun, so as to control the driving mechanism to rotate the solar wing, so that the sunlight is perpendicular to the solar wing as much as possible, so as to provide sufficient energy for the satellite.

But now, these technologies in the Han country have not made a breakthrough, so the most conventional design is adopted. The solar cells are directly pasted on the surface of the satellite, all of them are pasted, and more than 30000 pieces are pasted.

In this way, it also leads to a problem. These battery panels are black, absorbing heat, heating up the interior of the satellite, and making the internal battery temperature high!

This problem has never appeared in the past. The experts are surprised, and the experts engaged in satellite battery design are even more anxious. Their faces are red and their foreheads are sweating! Because the satellite is also like the human body, if the "high fever" continues, the light person will "burn" the system out of order; The heavy ones will completely "burn" the satellite and even cause an explosion!

Launching a satellite is a huge investment, but we can't drift like this.

Everyone was anxious. Even on the measuring ship, everyone was thinking of a solution.

However, there is no good way.

"Now, the top priority is to lower the temperature of the satellite first." hearing Colonel Chen's words, Qin Guan gave his opinion: adjust the attitude of the satellite at a large angle, or even put it down!

Nothing happened at first. After standing up, there was an accident. It showed that the attitude of the satellite was inappropriate and received direct sunlight, resulting in too high internal temperature. Put it down first and then study it slowly.

"Yes!" Colonel Chen said, "I'll report to the measurement and control center immediately."

Qin Guan's suggestion is risky, but even if it is risky, you should try it!

Soon, the measurement and control center sent a response and did it according to this suggestion!

With a series of instructions, the satellite in the sky lay down obediently. Then, the remote control system issued a command again and erected the satellite again. After such repeated adjustments, the satellite fell down, stood up, stood up and fell down in the sky, turned seven or eight somersaults in a row, and finally temporarily determined in a posture.

As the satellite avoided direct sunlight, the temperature began to drop.

"Mr. Qin, your opinion is not bad. According to the news from the measurement and control center, the satellite temperature has temporarily come down!" Colonel Chen said.

Qin sighed. The aerospace industry is also full of difficulties. Now he has personally participated in it, and he knows a lot of difficulties.

Just down, cooling down, whether the satellite can ensure normal communication with the ground, I don't know.

After that, it is still a difficult problem whether the satellite can be successfully fixed.

Let's leave this to aerospace experts. For Qin Guan, he's just a drop in.

Qin Guan returned to the destroyer. Now Qin Guan looks at the rippling sea again. Qin Guan knows that a tragic sea air war will start soon.

In front of Qin Guan, General Zhao and others were meditating on the chart, as if they were fighting this naval battle.

"It's strange that Baiyin obviously has aircraft carriers, but their aircraft carriers have hardly moved since the war," Captain Wei said.

"The aircraft carrier must have the whole system to have combat effectiveness." Qin Guan said: "the Niu people sank their 10000 ton warship, and the whole Baiyin navy was scared. They all wanted to avoid war and ensure safety, rather than take the initiative to attack. Moreover, even if they went out, the combat effectiveness of their aircraft carrier was not strong."

The aircraft carrier may 25 is the only aircraft carrier in silver. It belongs to the giant class of NiuGuo. Its full load displacement is less than 20000 tons and its maximum speed is only 24 knots. Such an aircraft carrier is destined to exist like chicken ribs.

Because the speed is not enough, the power of the catapult is not enough, so they can not move out, but whether the weather is beautiful or not. If the sky suck, the wind will not take off.

Because of the lack of advanced electronic equipment, the above A-4 skyhawk attack aircraft can only throw bombs to attack. How much combat effectiveness can it have?

If the Han country wants to build an aircraft carrier, it must not engage in such chicken rib goods. Although the super aircraft carrier has large investment and high operation cost, it is the only choice.

This is also the way that the west gradually came out. After the naval battle, the Niu people knew that their invincible aircraft carrier was no longer available, and later generations finally returned to the road of medium-sized aircraft carrier.

In order to develop aircraft carriers, the Han country must be a super aircraft carrier with a displacement of more than 50000 tons, and these aircraft carriers must also have a perfect supporting formation.

This road is still far away!

Thinking of the aircraft carrier formation, Qin Guan sighed in his heart that the aircraft carrier formation cannot be carried out when the national strength has not developed. At least, it will take more than ten years?

Now, let's take a look at this remarkable sea and air war and learn from it.
