Chapter 341: Ion thruster

Guo Jianming introduced the basic properties of Yan Jin to Ma Yiming. Let him think about all the details of this material.
After listening to Ma Yiming, he said with emotion: "Director Guo, you are really amazing. This material you researched can perfectly solve the problems we encountered.
It's just that the strength of this material is a bit low, but we can accept the performance it can give out by plating or spraying.
Although the cost is a bit high, the shuttle we developed can easily travel to and from space and earth. The average cost per use will be low enough to offset the high cost. "
After Ma Yiming finished speaking, he left and said, "Director Guo, I have been informed of this material. I am going to return to the company and continue to improve the space shuttle based on the performance of this material.
When the design is done, I'll come back to bother you. "
When Li Hao saw Ma Yiming leaving, he also said, "Listening to what you just said, the motivation has basically been worked out.
I don't know yet what kind of motivation our company uses. Just go back to the company with you to visit this motivation. Which design scheme does it use. "
Li Hao still remembers the universal motivation design scheme brought by Niu Zhengfeng. There are five motivations in total, including motivations using various principles.
He saw these five motivations, each of which could be realized. Touched by Niu Zhengfeng's spirit, he also wanted to go into space earlier to approve their project.
"Mr. Li, it's a coincidence. Today our motive for production is ready for a test run to verify the success of this motivation theory. You can immediately see which scheme it uses when you see this motivation." Ma Yiming said very happily.
He knew that after Li Hao saw the motivations made by their company, he could allocate a lot of resources if he was happy. They study the space shuttle much smoother.
Li Hao and Ma Yiming walked towards the military enterprise next to the scientific research building. These two places are not far away, only a few kilometers away.
If it is too far away, Ma Yiming is unlikely to come to the scientific research building often. Li Hao's frequency is not as high as hiss. One of the important reasons is that they are too close.
Li Hao walked into the heavily guarded military industry enterprise, and now identity verification is much easier, just put his palm on the sensor.
Under the leadership of Ma Yiming, they came to the motivation test drive laboratory.
Li Hao stood behind the transparent explosion-proof glass. He saw that there were two kinds of motivations, one big and one small.
Both motives are very slender. The small motive is five meters long and about 3o centimeters in diameter.
The big motive is 15 meters long and about one meter in diameter.
Looking at these two motives, Li Hao has not yet tested the car, and he knows that these two motives are not the motives for using chemical reagents.
From their structure, recall the design. It can be easily inferred that it belongs to the ion-electric drive.
He asked Ma Yiming directly: "This should not be the motivation to use conventional chemical reagents."
"General Manager Li ’s vision is really precise. This is not a conventional motive. We have conducted hundreds of millions of verifications through a scientific research assistance system. In the previously designed schemes, conventional motive cannot achieve the effect we want at all.
This motivation is our improved ion-electric pusher. Ma Yiming said the specific results.
Li Hao heard that this motive was an ion-electric propulsion machine, and he immediately recalled a design proposal at the time of the report.
Ion-electric propulsion is an efficient space motive. Its prototype has already been made, but because the motivation required technology is too high, it has never become mainstream.
The ion-propulsion machines produced now are characterized by low thrust and high specific impulse.
It can only be used to assist space propulsion, such as spacecraft attitude control, position maintenance, orbit maneuver, and interplanetary flight.
The principle of this motivation is to first ionize the gaseous working medium and eject the ions under the action of a strong electric field.
The principle is the same as the traditional chemical propulsion method, but the ion thruster requires a small amount of working fluid, which is the most suitable propulsion technology for long-distance navigation.
Li Hao also wanted to ask Ma Yiming about the specific performance of the ion drive. He saw the ion-electric impulse in the laboratory, which had emitted a light blue flame.
Knowing that the motive officially started the test run now, they waited only three minutes outside, and the motive in the laboratory immediately stopped working.
Niu Zhengfeng stepped out of the laboratory and shouted happily in his mouth: "Successfully, our theory is perfectly supported by experiments.
As long as the material problem of the motivation is solved, the motivation can be formally put into use. "
He walked out of the laboratory and saw Li Hao standing outside. He said with some restraint, "Welcome President Li to our company."
Ma Yiming immediately said to Niu Zhengfeng, "Lao Niu, please introduce to you the ion-electric pusher you designed."
Speaking of specific motivation issues, Niu Zhengfeng was no longer nervous, and introduced fluent language to Li Hao: "When I designed this general-purpose motivation, I realized that using chemical propellants would not achieve my purpose.
But in order not to give up any one solution, I designed five different motivations. Through our company's scientific research support system plus experiments. In the end, Ion electric drive was chosen.
This five-meter-long ion-electric propulsion machine was designed and improved by me. It is mainly used for navigating in the atmosphere and propelling aircraft in the atmosphere.
The propulsion it provides may be relatively weak, but the key is that this ion-electric propulsion engine requires much less fuel than a normal rocket.
Our ion-driven propulsion machine can maintain stable performance for a long time, and it will eventually be able to increase the space shuttle to a very high degree.
Its thrust is only a few Newtons, and the thrust is far less than the motive for making chemical reagents.
But the motivation of using chemical reagents can only maintain their thrust for a short time, but our motivation can be maintained for a long time.
Comprehensive comparison, using our ion drive, the final degree is greater.
It is also very easy to regulate power. At low power, it can fly in the atmosphere like a regular airplane. "
Niu Zhengfeng paused ~ EbookFREE.me ~ and continued to introduce: "This large 15-meter-long ion-electric propulsion motive is mainly used for navigation in the universe.
It uses a strong magnetic field, and its thrust is very powerful.
The motivation is to use radio frequency generators to heat the ions to 10 million degrees Celsius. In a strong magnetic field, the ions rotate at a fixed frequency. The RF generator is tuned to this frequency, which injects strong energy into the ions and continuously increases the propulsive force.
This motive is only suitable for use in the universe, and we also want to thank Director Bi Ye, who designed a strong magnetic field for us. In order to shape this motivation. "
Li Hao said with satisfaction: "Your motivation is well studied, I am waiting for the day when the space shuttle will go to heaven. The group will fully support you."
