Chapter 223 A thousand tons of thrust~
One thousand tons of thrust!

What crazy thrust data this is!
Even if Minister Liu is not a professional in rocket engine research, he probably knows what level the current thrust data of rocket engines in the world is. The [-]-ton level is the world's top technology, [-] tons?
Perhaps Da Mao could only achieve this when he was full of chicken blood.

However, that state is unsustainable, very cost-effective, simple and crude, absolutely not suitable for our situation, and not in line with science.

"Professor Zhao, our country's national conditions emphasize sustainable development, one step at a time~"

Minister Liu said tactfully that he was a little worried that Zhao Mo was drifting.

Zhao Mo was startled when he heard this, then he smiled and said: "Bu Liu, don't worry, I know what I know and I've calculated it~"

"Calculated?"

As soon as these words came out, Minister Liu was stunned again, thinking: "Can this also be calculated?"

If it were anyone else, he would have sneered at it, but this was Zhao Mo, so he immediately hesitated.

After thinking about it again, yes, I have calculated it. It seems that Zhao Mo's calculations have always been very good and he has been creating miracles.

Zhao Mo's strength lies in mathematics. He calculated lithium batteries, unmanned aircraft, and large models to predict earthquakes.Especially the large-scale earthquake prediction model, which was considered absolutely impossible before, has now become a reality and is very successful.

Rocket engines are indeed difficult and are one of the crown jewels of human industrial civilization, but can earthquake prediction models be even more difficult to calculate?
Minister Liu thought for a moment and shook his head secretly, no!

Rocket engines are not as difficult as earthquake prediction!
Therefore, Zhao Mo said that he had calculated the rocket engine and felt that it could be built. It was indeed possible and even possible to build it.

"Okay, I'll focus on this."

Minister Liu thought for a while and finally said.

He felt that since Zhao Mo was sure, it was totally worth trying.

"Ok~"

Zhao Mo smiled slightly.

Minister Liu's words were still very positive. The next day, the Bureau of Science and Industry organized a review of the "[-]-ton thrust rocket engine design plan", and then Minister Liu went to the site for the meeting in person.

Of course, this is also because Zhao Mo's name is resounding, and Jane is in the emperor's heart, so everyone dare not ignore it, and arrange an expert group to review it as soon as they get the plan.

People from relevant departments came, but the expert group mainly conducted the review. The opinions of the expert group determined the feasibility of Zhao Mo's plan and subsequent approval or rejection.

As a person involved, Zhao Mo must have been present at the scene.

Zhao Mo glanced at the expert group at the scene. In addition to Chief Engineer Wang, there were several aerospace academicians who were often seen in the media, such as Academician Long. Most of the others were unfamiliar and specialized in rocket engine research.Director Tan is naturally among the expert group, he is a master in this field.

China is still relatively low-key in terms of propaganda.

One is that technical people don’t like to show off, and they are low-key; the second is that they are not suitable for high-profile work to prevent various emergencies.Therefore, those who are often exposed in front of the media are basically no longer on the front line of research work, but have retired, and then become consultants, or simply have honorary titles.

So many people inside didn't know each other, and Zhao Mo wasn't surprised.

As a party involved, Zhao Mo first introduced his plan and the reasons: "...As a large thrust engine, the cost is high, and it must be considered to be reusable, otherwise it will be a huge waste of cost. There is no doubt that liquid oxygen methane The program is perfect for this.

...In addition, in order to greatly increase the thrust, a full-flow staged combustion design is adopted, which does not require high-pressure supplementary combustion.

This is the structural diagram I designed. You can take a look at it. It adopts a fully welded method and uses an internal through-structure to maximize space utilization...

The plan I designed can achieve a thrust of 1000 tons and a specific impulse close to the theoretical value of 390 seconds..."

The people here are not rocket engine experts, but they are also rocket experts. They also have deep knowledge of rocket engines, so Zhao Mo tried his best to explain the feasibility of his design plan.

Specific impulse is not simply a unit of working time, nor is it a simple unit of speed, but the impulse that a unit mass of propellant can produce.

The higher the specific impulse, the rocket can fly faster and further, which is a comprehensive indicator.

The specific impulse of the hydrogen-oxygen solution often exceeds 265, the solid fuel rocket is about [-] seconds, and the liquid oxygen kerosene is about [-] seconds.

Of course, it goes without saying that the specific impulse of plasma engines, photon engines, and nuclear fusion engines is too high.Among them, the lowest plasma engine has a theoretical specific impulse of more than 1000 seconds, or even nearly [-] seconds. It cannot be measured in miles~
Listening to Zhao Mo's explanation, everyone in the meeting fell into silence.

When Zhao Mo finished speaking, Zhao Mo noticed something. Academician Long, Li Dong, Chief Engineer Wang and others all subconsciously looked at Tan Kaihua, who was also silent.

"It seems that Director Tan's opinion is very important~"

Zhao Mo thought secretly.

What surprised Academician Long, Chief Engineer Wang and others was that Tan Kaihua remained silent in the face of their gazes, as if he did not feel their gazes. "Strange, what's going on?"

Commander Wang was a little confused and thought to himself: "Did Zhao Mo conquer Kaihua in the Sixth Aerospace Institute?"

He has retired, so many front-line things are not known immediately and can only be speculated based on common sense.

Academician Long's face was a little confused at first, but it soon turned into relief. He thought about what Li Dong reported to him. Zhao Mo's performance in the Sixth Aerospace Academy made him, the later audience, feel incredible.

He couldn't help but glance at Zhao Mo again and thought: "The plan is logically self-consistent. If Xiao Tan thinks the problem is not big, he can try to develop it. But, how does this young man's brain grow? How long has it been?"

"Ahem~ If you have any questions or comments, please mention them, right?"

Minister Liu saw that everyone was silent, so he coughed, breaking the quiet atmosphere.

"Professor Zhao, I have no problem with other aspects. I only have two problems. The first problem is such huge pressure that no material in the world can meet your design requirements; the second problem is that the fuel you mentioned is fully burned. How do you ensure that the combustion effect of your design is sufficient?"

Tan Kaihua finally spoke. He pointed out two key issues, which were also two ambiguities in Zhao Mo's design plan, namely the adequacy of the engine body material and the fuel combustion process!
As soon as these words came out, everyone looked at Zhao Mo, waiting for his answer.

Tan Kaihua's two questions are the core questions and what they want to know.

If you want to have a large thrust, the energy of the injection must be large, and the reaction force must also be large, which places extremely high requirements on the main material of the engine.

If the strength, toughness and other properties are not up to standard, the explosion will only happen in an instant.

The adequacy of fuel combustion is one of the necessary conditions for high thrust, and it is also the key to reducing the volume and weight of the entire rocket engine as much as possible.

The combustion is more complete, the thrust is greater, the size of the engine can be made smaller, and the weight will naturally be reduced.

Especially the plan designed by Zhao Mo requires a thrust of 1000 tons, which is unprecedented. These two key issues will only be more than ten times more difficult than their current design plan!
Unless these two problems are solved, Zhao Mo's plan will be empty talk.

"Yes, these are two core issues~"

Zhao Mo, however, was well prepared and said with a slight smile: "For these two problems, I already have a preliminary plan to optimize from the perspective of overall control. I have calculated that through structural optimization, the performance of the material only needs to be improved by two times. You can achieve..."

As he spoke, he took a whiteboard pen and wrote some equations on the whiteboard.

F=ma!

P【av/at+（v.△）v】=-△P+pg+μ△V!

……

Tan Kaihua: "..."

Academician Long, Li Dong, Minister Liu, Chief Engineer Wang and others: "..."

No, just explain. How can such a good person write mathematical formulas?

But soon, they understood what Zhao Mo had written. It was not just a mathematical formula, but also a physical formula.

"NS equation?"

Tan Kaihua was startled, stood up suddenly and asked, "Have you solved the NS equation?"

Academician Long, Li Dong, Chief Engineer Wang and others also looked at Zhao Mo with surprised expressions. They didn't expect that Zhao Mo would give them such a big move!
Minister Liu was startled for a moment, then he came to his senses and asked in a low voice, General Manager Wang, who was sitting next to him: "Is it one of the seven Millennium Prize problems set by the America Clay Mathematics Institute?" NS equation?"

General Master Wang gave him a strange look, as if asking him why he asked such a strange question since he was also a science major.Minister Liu's face turned red when he saw it, and he couldn't help but cough a few times.

"It's that equation!"

General Master Wang nodded and confirmed, and then in order to prevent him from asking again, he explained: "This is the equation describing incompressible fluid and compressible fluid. The NS equation of the Millennium Award refers to NS in the three-dimensional space. The problem of the existence of smooth solutions to systems of equations.”

Minister Liu nodded with a sudden look on his face, indicating that he understood.

General Master Wang didn't know whether he really understood it or pretended to understand it. He didn't bother to pay attention. After Tan Kaihua's question, he couldn't help but ask Zhao Mo: "Xiao Zhao, you solved the smooth solution of NS equations." Is there a question of sex?”

This is one of the seven major problems of the millennium, and it is also one of the major unsolved problems in physics and mathematics. It is of great significance to both physics and mathematics!
Especially for physics, this solves the turbulence problem of the world's puzzle!
Turbulence is not just turbulence in water, but turbulence in all fluids.At the level of the universe, everything flows, and the formation of the universe is related to turbulence.

On a practical level, aerospace, geophysics, atmosphere and ocean, daily life, etc., will all benefit!
