Vol 2 Chapter 466: Kuafu optimized design of nuclear battery

Lei Tiantang is very concerned about the energy that supports the long-term operation of satellites and space telescopes, because the satellites and other types of probes traveling in space have very strict requirements on power sources, such as light weight and small size. It can withstand strong vibration, and it also requires a long service life!
Therefore, several Jupiter detectors launched by foreign countries in the early 1970s were equipped with high-performance nuclear batteries made of plutonium oxide and molybdenum.
So this kind of mature nuclear battery technology has been his eye. It is necessary to know that the energy used by the satellites and space telescopes developed by the company is still composed of solar panels and the company's high-performance battery pack.
They all use their own space engines to change orbit in space, and achieve the purpose of orbit change or acceleration by ejecting a certain amount of gas.
There is no problem with these features when the solar system is not too far away from the sun in the fixed orbit of the earth, because these probes have their own orbits.
It itself can obtain a stable energy supply through solar panels for a long time, and the fuel it carries for orbit change and acceleration is rarely used, so only a small amount of fuel can be used for these detectors for several years.
But the satellites and space telescopes that Lei Tiantang intends to throw into the nebula will not work. It will take at least half a year for them to reach the periphery of the "new home"!
Because the body of the small black hole is a little closer to the "New Home" star system, it 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 star system. Normal operation.
However, the black hole itself cannot control the change of the surrounding space latitude. It is estimated that after the real combination of Lei Tiantang and the small black hole, he can fully control the small black hole.
The change in the surrounding space latitude can also affect the star system, so before the small black hole is still some distance away from the star system, for the safety of the star system, it can only stop at a safe distance.
The safe distance from Lei Tian Tang is set at 1 billion kilometers. According to calculations by him and Kuafu, beyond this distance, with the mass of the small black hole itself, the space latitude it disturbs will not affect the "New Home" star system.
Satellites and space telescopes and other detectors can only use the powerful position of the small black hole to eject toward the "new home" star system from a safe distance of 1 billion kilometers!
No matter how fast their initial speed is, it will take a very long time to fly a long journey of 1 billion kilometers, and half a year is the least estimate.
And for such a long time, these satellites and other detectors have to be in working condition all the time. After all, all the data over there are estimated, and the specific data need to be detected before they can be known.
At the same time, these detectors must constantly adjust their orbits during the flight, and select their respective detection locations through the detected star system data, and these detectors need a substantial deceleration process before they approach the detection location!
Through the built-in fuel, the method of reverse injection is adopted to reduce the speed of the detector to facilitate the detector to enter the set detection track!
Therefore, the energy they carry is very important, and the requirements have become higher, because all these detectors can only constantly adjust their position and speed based on the data they detect, and there is no continuous and stable energy source. It is absolutely impossible.
"Boss, don't worry! Nuclear battery technology is not top-notch technology. I have searched for many design solutions on the Internet, and I have verified these solutions one by one.
In the end, we chose to use plutonium-238 as the fuel for our nuclear battery. Through the decay of plutonium-238, it emits alpha particles and generates heat, which is used to generate electricity.
Plutonium is the 94th element. It is the heaviest element naturally occurring in nature and heavier than uranium. Its stable isotope is plutonium 244, with a half-life of approximately 80 million years.
The half-life of plutonium 238 is 87.74 years. When it decays, it releases alpha particles and emits a lot of heat. This makes plutonium 238 spontaneously ignite under certain conditions and plutonium can ignite spontaneously, which makes it look like Like a glowing ember.
The heating power of 1 kilogram of plutonium 238 is equivalent to an electric furnace with a power of 570 watts, and it lasts for several decades without interruption.
The nuclear battery made of plutonium-238 can stably provide about 125 watts of power output under any conditions 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 nuclear batteries made of plutonium-238 on all our detectors, then our detectors will have a long-lasting energy supply!
The thermoelectric conversion rate of nuclear batteries is not very high. However, nuclear batteries can not only be used to generate electricity, especially in the cold universe, the temperature can even reach more than minus two hundred degrees Celsius!
The nuclear battery can also provide thermal energy for these detectors. Using this thermal energy, certain sensitive parts on the spacecraft can withstand the test of low temperatures!
So the boss you choose to use nuclear batteries in our transformation design is an absolutely correct choice! "Quafu said with a smile.
"That's for sure! I wouldn't be a fool if I don't need such a good thing! But have you already made a nuclear battery for testing? Show me it! Also show me its data Look!" Lei Tiantang said happily.
"Good boss~EbookFREE.me~ you see, this is the nuclear battery I optimized using data obtained from the Internet. Its fuel is plutonium-238, and it is made into a ceramic briquette of plutonium dioxide.
A single nuclear battery can provide 880 watts of power in the initial stage. After detailed testing, even more than ten years later, such a nuclear battery can still provide 670 watts of power!
With such a power nuclear battery, install 3-4 of our various detectors, and then our detectors can operate as they wish!
And its other data, I will also introduce to you..."
While playing the test video of the nuclear battery on Lei Tian Tang's computer, Kuafu triumphantly introduced him to various performance data.
Although he found the design of the nuclear battery from the Internet, he also contributed to the optimization of those designs, so when he introduced it to his boss, his mood became very good.
"Okay! Kuafu, your job is really good! But the nuclear batteries you make for testing must be subjected to various extreme tests! Their quality and safety issues are related to the detector. Can it be used!"
