“Hmm!”
A researcher bowed his head slightly and replied:
“It can realize precision navigation and positioning of satellites, and improve the orbital accuracy and control capabilities of satellites.”
“Moreover, MEMS fiber gyroscopes have the advantages of small size, light weight, low power consumption, good temperature stability and high reliability like fiber lasers.”
“Some time ago, our Institute of Microsystem and Information Technology of Longguo Academy of Sciences developed a miniature inertial navigation system based on MEMS fiber optic gyroscope, which can be used for microsatellites!”
“I think this technology can be applied for directly to our microsatellite system!”
Lu agreed: “Our ideas coincide.
“If I can apply for the technology directly, I will apply directly, which can be regarded as giving us some space for our already insufficient research time.” After all, after our mission is over, there will be no small trouble later.
“At that time, I will formally apply to the above.”
“Next, I want to ensure that the microsatellite system does not have a safety level failure, or once a safety level fault is found, it needs to be repaired as soon as possible.”
“We have to introduce MEMS oscillators, filters.”
“It performs well in achieving fault detection and isolation of satellites and improving the safety and reliability of satellites.” And the quality factor is high, the University of Michigan has tried a fault detection system based on MEMS oscillators before, we can also try it this time…”
Lu Yu arranged the next experiment in great detail, and asked his assistant to record it in a log.
As long as the general policy is confirmed first, the next action can be done step by step, and it will take a lot of time.
But on a technical level… The difficulty will not be particularly high!
After all, what Lu Yu has to solve now is not only a technical problem, but also needs to free up enough time to find a way to prevent the black hands that the Eagle Country is likely to do!
Now the reason why he did not tell the group about this for the time being is also so that they can first concentrate on building MEMS, and when this problem is completely over, they will devote themselves to finding ways to arrange preventive measures!
“Everyone should understand what we should do next.”
Lu Yu looked around and asked.
“Understood, Chief Engineer Lu!”
“Okay, then we’re ready to start work. Everyone took a break for an hour, and after 3 hours we reunited in the conference room. ”
Huh?”
Everyone present was slightly stunned, and they didn’t expect that Lu Yu would let everyone rest for 3 hours. They thought that according to Lu Yu’s time, they should start construction immediately!
After all, an hour is not a long time, but it can also show an attitude.
“Let you go and rest for 3 hours first, and you will go first.”
“I still have some information that I need to prepare for you in advance.”
“When the research officially begins, everyone wants to have that long rest, so they can only dream at night.”
Lu Yu threatened half-jokingly.
“Yes, Chief Engineer Lu.”
“We’ll go rest now.”
The researchers turned pale after hearing this, and immediately left the conference room, not staying for long.
Although they also know Lu Yu’s words, they are actually joking.
But if the next research officially starts, it may be really difficult to rest for as long as 3 hours in one breath, not counting sleep!
Sometimes free time is something that you only know how precious it is when you lose it.
After all the researchers left the conference room, Lu Yu changed to a more relaxed sitting position and reclined in a chair.
“You go get me some food.”
“It’s better to have something with a higher energy content.”
“Take a little more, I will use my brain to a greater extent, and I need to replenish it in time.”
Lu Yu explained to the assistant beside him.
Before the experiment begins, he does have one more important thing to do in advance, that is, to confirm in detail whether his concept is correct.
Or to be specific, how much can the micro-motor system built on the microsatellite network system improve its safety?
If you conduct a test specifically for this matter, it is too wasteful of resources.
However, it doesn’t take long to make a rough estimate in your head.
“Yes, Chief Engineer Lu!”
The assistant slowly left the conference room, and about 5 minutes later brought a large plate full of chocolates: “Chief Engineer Lu, have you seen so much enough?” ”
Chocolate is really a good thing to replenish energy.
“Enough, you also go to rest for a while, let me be alone.” Lu Yu said with a smile.
“Yes.”
After the assistant left the conference room, there was only Lu Yu left in the huge conference room, he first stood up and relaxed his muscles, confirmed his physical condition, and then began to formally test and estimate!
Just when Lu Yu was planning to use the high-speed calculation system in his mind to calculate the information he already had.
“Ding!”
A familiar system prompt sounded in his brain!
[Congratulations to the host for reaching the hidden requirement in the cumulative number of calculus! ] ”
Hide requirements?”
Listening to the system prompt sound in his mind, Lu Yu’s eyes showed a look of doubt, what does this mean?
When this function was unlocked in the system, when it was the [Red Sun] project, he helped Su Xiaoxiao solve a theory at the level of micromolecular food.
For more than half a year, this function is indeed the most familiar one for Lu Yu.
After all, he is indeed very convenient, equivalent to having a Shenwei Taihu Light in his head, relying on the data in his mind to easily calculate many conclusions that take a lot of time to draw, and does not require any steps.
I have to say what’s the trouble.
That could be that fast calculus would place a huge burden on the body and brain.
After all, according to the law of conservation of energy, it does not consume electricity, so it can only consume some of its own biological energy.
At the time of the [Red Sun] project, in order to calculate the impact of the earthquake on the Tokmak device, it was because the amount of calculation was too huge, resulting in the body’s energy replenishment was not timely, and the eyes were directly dark!
Fortunately, the medical staff sent themselves to the hospital in time, there was no big problem, and there were no sequelae.
So this time Lu Yu also prepared his heart in advance.
Ask your assistant to prepare more food for himself before the calculation begins.
Everything was ready, but who would have thought that a moth suddenly appeared in the system at this time?
“Has anything changed since the hidden requirement was met? There must be some rewards.
Lu Yu secretly calculated in his mind.
Just when he wondered what exactly would change in the next moment of the system… The voice sounded again!
【Ding! 】
【Congratulations to the host for reaching the hidden requirements, the calculation function is being upgraded, please wait for the host! 】 】
【1%… 2%… 3%… 4%… 99%.. 100%】
【Congratulations on the upgrade of the host calculus function to unlock new function simulation experiments! 】
“What do you mean?” Is this an upgrade of the original function?
“Does it improve the accuracy of the calculus, or does it expand the range of calculus?”
Lu Yu frowned slightly, and began to try, what new changes have occurred in the high-speed calculation function that originally existed in his mind?
This time, he was immediately shocked!
It has to be said that the ability of the system is also really outstanding.
After completing the upgrade and unlocking the new function simulation experiment, Lu Yu was surprised to find that the high-speed calculation function that originally existed in his mind suddenly became a lot more general, if it was originally only able to calculate some complex data, then at this moment it was even possible to conduct large-scale simulation of the entire experiment!
It doesn’t sound like there is much difference between the two.
But if you put it at the practical level, the difference between the two can be called a world and a place!
The reason is also very simple, if only the data is calculated, although it can be confirmed to a certain extent whether the data obtained is correct, but the number is dead after all, but people are alive.
An experiment may have no problem in terms of numerical values, but it is likely that due to some human factors or other unnameable factors, some more or less deviations in the values will occur, so that the entire experiment will fail!
However, the upgraded high-speed calculation function is different.
It can consider several times more things at once.
If this function had come earlier, Lu Yu would have been able to realize what the problem would have been after this test started before the plasma laser cannon was fired!
This will avoid having to resist time pressure to solve troubles when you temporarily hold Buddha’s feet at launch!
Although this function came a little late, Lu Yu is still very satisfied, after all, it is always better than nothing.
“After this feature has been upgraded, the next task I want to carry out is much more convenient.”
“It’s that the load on my brain and body may be greater, and the chocolate on this plate alone is estimated to be not enough for me to eat alone.”
Lu Yu thought about it, and for the sake of safety, asked his assistant to come over again and get more chocolate to put on the table.
If you really find that the consumption is too large on the way to calculate, you can also make a supplement to the body in time.
“Chief Engineer Lu, you are sure so much: Can you really finish eating? The
assistant blinked, holding a large pile of chocolate, protein bars and other energy-replenishing foods, and placed it in front of Lu Yu with some uncertainty!
Such a large amount, he pushed it over with a cart, and then held it on Lu Yu’s table one by one.
This weight.
It is estimated that it is enough for ordinary people to eat for several days.
“Of course, I can’t finish eating alone.”
“But isn’t there still you?”
Lu Yu said casually: “Anyway, when the research officially begins, everyone is hungry and wants to eat something, just take it and eat it yourself.”
“And not all of it was for me to eat.”
“Also, my subordinates forgot about this.”
The assistant said awkwardly.
At first, listening to Lu Yu’s tone, he thought that Chief Engineer Lu planned to eat all these things alone… Now that Lu Yu woke up so much, he realized what a stupid thing he had just said.
Such a big stack of things, even pigs can’t eat it!
The assistant left the room awkwardly.
What he didn’t expect was… Lu Yu said so, but such a large plate of food, Lu Yu really planned to solve it all by himself!
Wait until the assistant leaves the room again.
Lu Yu finally began formal research work.
He first sorted out the information he had at hand, summarized all the data he already had about the microsatellite network, and then… Then mess this information with the data of the micromotor system in your mind!
Microsatellite networks generally weigh less than 500 kilograms, making them lighter than ordinary satellites, easier to move and less vulnerable to space junk.
Lu Yu has also long understood that the introduction of MEMS can improve the performance of microsatellites.
Because of the existence of MEMS, it can achieve precise control and adjustment of microsatellites, including but not limited to attitude control, but how much performance can be improved, Lu Yu still lacks an accurate understanding of this!
And his special calculus this time is to solve this problem!
After Lu Yu stuffed a few protein bars and chocolate into his mouth, he began to simulate the experimental equipment calculation attempt.
After closing his eyes, countless experimental facilities and equipment, as well as data, seemed to exist between illusion and reality, constantly emerging in his mind!
“Purpose of the experiment: to compare the performance differences in attitude control between microsatellites using MEMS and microsatellites without MEMS.”
“Experimental equipment: two microsatellites of the same configuration (mass of 10 kg, length, width and height of 30 cm)
” “One of them is equipped with a MEMS gyroscope and a MEMS accelerometer as a attitude sensor, and the other with a conventional gyroscope and a conventional accelerometer as a attitude sensor.”
“Two rockets of the same configuration (mass of 1000 kg and length of 10 meters) carrying two microsatellites; A ground monitoring station for receiving and analyzing attitude data from two microsatellites. According
to the principle of controlling variables, Lu Yu began to set up different experimental equipment in his mind.
Then import the data that you know into the experimental equipment.
After the goal of this step is solved, the specific experiment officially begins!
It seems that he feels that his body and brain are a little weak, and while conducting research, Lu Yu’s hand did not rest at all, grabbed a few more chocolate bars into his mouth, and gobbled them up.
Taste doesn’t matter, energy replenishment is key.
“Experimental steps: launch two rockets into a predetermined low orbit (at an altitude of 500 km), respectively, and release two microsatellites into orbit.”
“First, let the two microsatellites perform a attitude adjustment task respectively, that is, from the initial attitude (pitch angle 0 degrees, roll angle 0 degrees, yaw angle 0 degrees), and then change to the target attitude (pitch angle 30 degrees, roll angle 45 degrees, yaw angle 60 degrees).”
“Record the time and energy consumption required by the two microsatellites to perform attitude adjustment tasks, and transmit the data to the ground monitoring station for analysis.”
The satellite in my mind seemed to really start to rotate slowly according to Lu Yu’s thoughts!
And the data was also transmitted along the illusory device into the ground monitoring station envisaged in Lu Yu’s mind!
Massive data, ready to come out!
“End of experiment, start deriving results!”
