Guo Jianhao carefully introduced the basic properties of Yanjin to Ma Yiming. It allows him to think carefully about all aspects of this material.

After Ma Yiming listened, he said with emotion: "Director Guo, you are really amazing. The material you have developed can perfectly solve the problems we encountered.

It's just that the strength of this material is a little low, but using electroplating or spraying, the performance it can exert is acceptable.

Although the cost is a bit high, the space shuttle we developed can easily travel back and forth between space and Earth. The average cost per use will be low enough to offset the high cost. ”

After Ma Yiming finished speaking, he said goodbye and left: "Director Guo, I have learned the information of this material, and I am ready to return to the company and continue to improve the space shuttle according to the performance of this material."

I'll come back and bother you when it's ready. ”

Li Hao saw that Ma Yiming was leaving, and he also said: "Listen to what you just said, the engine has been basically developed."

I don't yet know what kind of engine our company has. Just go back to the company with you to see this engine. Which design scheme is it used. ”

Li Hao still remembers the general-purpose engine design scheme brought by Niu Zhengfeng, which is a total of five engines, including engines with various different principles.

He saw that each of the five engines had the potential to be realized. I was also moved by Niu Zhengfeng's spirit, and wanted to go into space earlier, so I approved their project.

"Mr. Li, it's really a coincidence. Today we are preparing for the first test run of the engine to verify the success of this engine theory. When you see this engine, you immediately understand which one it is going to do. Ma Yiming said very happily.

He knew that Li Hao could allocate a lot of resources as long as he was happy after reading the engines manufactured by their company. It's going to be a lot smoother for them to develop the space shuttle.

Li Hao and Ma Yiming walked towards the military industrial complex next to the scientific research building. The two places are not far apart, only a few kilometers apart.

If it was too far away, Ma Yiming would not be able to come to the scientific research building often. Li Hao didn't come as often as he came, and one of the important reasons was that they were too close.

Li Hao walked into the heavily guarded military industrial enterprise, and now the identity verification is much more convenient, and he only needs to put his palm on the sensor.

Under the leadership of Ma Yiming, they came to the laboratory of engine testing.

Li Hao stood behind the transparent explosion-proof glass, and he saw that there were two engines being tested, one large and one small.

Both engines have a very slender feel. The small engine is five meters long and about 30 centimeters in diameter.

The large engine is 15 meters long and about one meter in diameter.

Li Hao looked at these two engines, and now he has not tested them, and he knows that these two engines are by no means engines that use chemical reagents.

From their structure, recall the design scheme. It can be easily inferred that it belongs to the ion electric propulsion engine.

He asked Ma Yiming directly: "This should not be an engine using conventional chemical reagents." ”

"Mr. Li's vision is really accurate, this is not a conventional engine. We have carried out hundreds of millions of verifications through scientific research assistance systems. We found that in the previous design, the conventional engine could not achieve the effect we wanted.

This engine is our improved ion electric propulsion engine. Ma Yiming said the specific results.

When Li Hao heard that this kind of engine was an ion electric propulsion engine, he immediately recalled a design plan at the time of the report.

The ion electric propulsion engine is a highly efficient space engine. Its prototype had already been made, but it never became mainstream because of the high level of technology required for this engine.

The characteristics of the current ion electric propulsion engine are small thrust and high specific impulse.

It can only be used to assist in space propulsion, such as spacecraft attitude control, position keeping, orbital maneuvering, and interstellar flight.

The principle of this type of engine is to first ionize the gaseous working fluid and accelerate the ejection of ions under the action of a strong electric field.

The principle is the same as that of the conventional chemical propulsion method, but the ion thruster requires a small working fluid mass, and is the most suitable technology for long-distance navigation among the propulsion technologies that have been put into practical use.

Li Hao originally wanted to ask Ma Yiming about the specific performance of the ion electric propulsion engine. He saw that the ionic electric propulsion engine in the laboratory was already spewing light blue flames.

Knowing that the engine had officially started testing, they waited outside for just three minutes, and the engine in the lab immediately stopped working.

Niu Zhengfeng walked out of the laboratory, and he shouted happily: "It's successful, our theory is perfectly supported by experiments."

As long as the material problem of the engine is solved, the engine can be officially put into use. ”

He walked out of the laboratory and saw Li Hao standing outside, and said a little reservedly: "Welcome Mr. Li to visit our company." ”

Ma Yiming immediately said to Niu Zhengfeng: "Old Niu, you introduce to Mr. Li the ion electric propulsion engine you designed. ”

When it came to the specific engine problem, Niu Zhengfeng was no longer nervous, and introduced to Li Hao in fluent language: "When I designed this general-purpose engine, I found that it was impossible to achieve my purpose by using chemical propellants.

But in order not to abandon either option, I designed five different engines. Through our company's research support system plus experiments. In the end, the ion electric propulsion engine was chosen.

This five-meter long ion electric propulsion engine was improved by my original design. It is mainly used for navigation in the atmosphere and propulsion of aircraft in the atmosphere.

The propulsion it provides may be relatively weak, but the key point is that this ion-electric propulsion engine requires much less fuel than a normal rocket.

Our ion-electric propulsion engines are designed to maintain consistent performance over time, which will eventually be able to accelerate the space shuttle to very high speeds.

Its thrust is only a few newtons, and its thrust is far less than that of an engine that makes chemical reagents.

But with the use of chemical agents, their thrust can only be maintained for a very short time, while our engines can last for a long time.

In a comprehensive comparison, using our ion electric propulsion engine, the final speed is greater.

It is also very convenient to adjust the power. Used at low power, it is possible to fly like a conventional aircraft in the atmosphere. ”

Niu Zhengfeng paused and continued: "This 15-meter-long large ion electric propulsion engine is mainly used for navigating in space.

It uses a super magnetic field and has a very powerful thrust, far exceeding that of today's chemical engines.

This engine uses a radio frequency generator to heat ions to 1 million degrees Celsius. In a strong magnetic field, the ions rotate at a fixed frequency, and the RF generator is tuned to this frequency, injecting the ions with extremely strong energy and increasing the propulsion force.

This kind of engine is only suitable for use in the universe, and we would also like to thank Director Bi Ye, who specially designed the super strong magnetic field for us. in order to make this engine take shape. ”

Li Hao said with great satisfaction: "Your engine has been developed very well, and I am waiting for the day when the space shuttle will go into the sky." The Group will fully support you. ”
