Chapter 456

Lei Tiantang is very concerned about the energy to support the long-term work of satellites and space telescopes. Because the satellites and other detectors traveling in space have strict requirements on power supply. They should be light in weight, small in size, capable of withstanding strong vibration, and long service life!

Therefore, the high-performance nuclear cells made of plutonium oxide and molybdenum were installed on several Jupiter probes launched abroad in the early 1970s.

Therefore, this mature nuclear battery technology has been focused on by him. We should know that the energy used by these satellites and space telescopes and other detectors developed by the company is composed of solar panels and high-performance battery packs of the company.

They use their own space engines to achieve orbit change or acceleration by ejecting a certain amount of gas.

There is no problem with these features in the fixed orbit of the earth where the solar system is not too far from the sun, because these detectors have their own orbits.

It can obtain stable energy supply through solar panels for a long time. The fuel it carries for orbit change and acceleration is rarely used. Therefore, it can use these detectors for several years with only a small amount of fuel.

But the satellites and space telescopes that Lei Tiantang intends to throw into the nebula will not work. It will take them at least half a year to reach the periphery of the "new home"!

Because when the body of a small black hole is a little closer to the "new home" star system, he can only choose to stop, because even Lei Tiantang can control the gravity of the small black hole body, so that its gravity will not interfere with the normal operation of the star system.

But the black hole itself has no way to control the change of the latitude of the surrounding space. It is estimated that Lei Tiantang can completely control the body of the small black hole after it is really combined with the noumenon of the small black hole.

The change of the latitude of the surrounding space can also affect the stellar system, so the small black hole can only stop at a safe distance for the safety of the stellar system before it is a certain distance away from the constant galaxy.

The safe distance is 1 billion kilometers. According to his and Kuafu's calculation, the space latitude of the small black hole will not affect the "new home" star system.

But satellites and space telescopes and other detectors can only use the powerful position of small black holes to eject towards the "new home" star system at a safe distance of 1 billion kilometers!

Even if they are fast at the beginning, it will take a long time to fly a billion kilometers. Half a year is the least estimate.

For such a long time, these satellites and other detectors have to be in working state all the time. After all, all the data over there are estimated, and the specific data need to be detected after detection.

At the same time, these detectors have to adjust their orbits constantly during the flight, and choose their respective detection positions through the detected stellar system data. Moreover, these detectors need a large deceleration process before approaching the detection position!

Through the self-contained fuel, the reverse injection method is adopted to reduce the speed of the detector, so as to facilitate the detector to enter the set detection orbit!

Therefore, the energy they carry is very important, and the requirements become higher, because all these detectors can only adjust their position and speed according to the data detected by themselves, and it is absolutely impossible to do without continuous and stable energy.

"Don't worry, boss! The technology of nuclear battery is not a top-notch technology. I have searched many designs on the Internet and have verified them one by one.

Finally, we chose to use plutonium 238 as fuel for our nuclear cells, which, through its own decay, releases alpha particles and generates heat, which is used to generate electricity.

Plutonium, element 94, is the heaviest element in nature, heavier than uranium. Its stable isotope is plutonium 244 with a half-life of about 80 million years.

The half-life of plutonium-238 is 87.74 years. When it decays, it releases alpha particles and releases a lot of heat. This makes plutonium-238 self ignite under certain conditions even if its quantity is small, which makes it look like a glowing ember.

The thermal power of one kilogram of plutonium 238 is equivalent to that of an electric furnace with 570 watts of power, and its duration is decades without interruption.

The nuclear cell made of plutonium-238 can provide a steady power output of about 125 watts in any condition at the beginning of the mission, and the power can be maintained at about 100 watts after 14 years.

As long as we install more than two plutonium-238 nuclear batteries in all our detectors, our detectors will have enough long-term energy supply!

The thermoelectric conversion rate of nuclear cells is not very high. However, nuclear cells can not only be used to generate electricity, especially in the cold universe, its temperature can reach more than minus 200 degrees Celsius!

The nuclear battery can also provide heat energy for these detectors. Using this heat energy, some sensitive parts on spacecraft can withstand the test of low temperature!So, boss, it's absolutely right that you choose to use nuclear batteries in our retrofit design! " Kuafu said with a smile.

"That's for sure! If I had such a good thing, I would not have used it! Can't you test all your batteries? Show me it! Show me its data, too Lei Tiantang said happily.

"Good boss, you see, this is the nuclear cell that I optimized using the data I got from the Internet. Its fuel is plutonium 238, and it is made into ceramic briquettes of plutonium dioxide.

A single nuclear cell can initially provide 880 watts of power. After detailed testing, even more than a decade later, such a nuclear battery can also provide 670 watts of power!

This power of nuclear batteries, in our various detectors to install it 3-4, our detector then how to operate can be how to operate!

As well as other data, I'd like to introduce it to you...

while playing the test video of nuclear battery on Lei Tiantang's computer, Kuafu introduced various performance data to Lei Tiantang with pride.

Even though he didn't make great contributions to the design of the network, he didn't make a contribution to the design of the network.

"Good! Kuafu, your work is really good! However, the nuclear batteries you make for testing must be subject to various limit tests! Their quality and safety are related to whether the detector can be used or not
