Siheyuan: Originally I just wanted to be a little transparent

After Lin Shengli finished speaking, Nie Lao, who was sitting beside him, spoke: "I can explain this matter to Comrade Shengli."

"Comrade Shengli has participated in many projects, and a lot of information may have been obtained from comprehensive analysis of various projects."

"The authenticity of some things analyzed by Comrade Shengli is still credible."

With Mr. Nie's endorsement, Lin Shengli continued: "Several leaders, we all know that at this stage, in terms of missile or rocket technology, Yingjiang and Mao Xiong have always been at the forefront of the world."

"Especially after their two countries used advanced rocket technology to send their respective satellites into space one after another, Yingjiang and Mao Xiong have been clamoring to be the first people to set foot in space."

"Since they dare to shout this slogan, I think it may not be groundless."

"Judging from the advanced level of launch vehicle technology their two countries have mastered, this matter may be true."

"Now, we have just begun to think about developing a launch vehicle based on missile technology."

"When we complete the research, we can send at most a small satellite into space later."

"But what about Yingjiang and Mao Xiong? They are already preparing to send people into space. Isn't this technological gap too big..."

After hearing what Lin Shengli said, Mr. Nie who was sitting aside asked, "Comrade Shengli, your analysis is very constructive."

"Then what do you think are the chances of Yingjiang and Mao Xiong succeeding in manned spaceflight?"

"In other words, have their technological level really reached the point where they can send people into space?"

Although Lin Shengli knew the very correct answer, he couldn't tell it.

Otherwise, this is not an analysis, but an advance prediction and spoiler that he cannot explain clearly!

Lin Shengli thought for a while and felt that he could put it in a slightly more euphemistic way.

So, Lin Shengli replied to Nie Lao: "Nie Lao, these analyzes are just a comprehensive analysis based on the information from various aspects and some information I can find."

"As for what the real facts are, I can't make a more accurate judgment."

"But from my personal point of view, with the technology mastered by Yingjiang and Maoxiong on the launch vehicle, there should be no problem in sending individuals to space."

After hearing what Lin Shengli said, everyone present fell into silence.

Although everyone knows that Yingjiang and Maoxiong's technology, especially aerospace technology, has always been ahead of the world, they never expected that the gap between us and others would be so big.

As Lin Shengli analyzed, we are still developing launch vehicles based on missile technology. If we succeed, we will be able to send a small satellite into space.

But as for others, they are sending people into space. This technological gap is indeed too big!

After a while, it was Nie Lao who broke the silence.

"Comrade Shengli, was your original intention in designing this launch vehicle to keep up with Yingjiang and Mao Xiong, and we also started to engage in manned spaceflight?"

"Also, I would like to ask, how do you think we should proceed with our future development in aerospace?"

Regarding Lao Nie's question, Lin Shengli thought for a moment and said, "Lao Nie, it's actually very difficult for me to answer these questions of yours."

"These issues are important matters for you and the higher-ups to consider. As a technical person, I can only briefly express my views from a technical perspective and from my own perspective."

"From my personal point of view, I think we should use the information I provided as a reference to develop this launch vehicle that exceeds [-] tons."

"We previously set the goals we wanted to achieve too low because we did not have the corresponding technical reserves and reference objects in the country. We were crossing the river by feeling the stones."

"But since Dean Qian organized relevant personnel to conduct demonstration and research on the information I produced, the results also prove that it is feasible."

"So, now we have the corresponding reference material, and we have to make use of it."

"Although we will encounter more difficulties in this process."

"But once we succeed, at least in the field of launch vehicles, we will be able to keep up with the most advanced pace in the world."

"As long as we can develop this launch vehicle, not to mention sending satellites into the sky, even our own manned spaceflight can be put on the agenda in advance."

After listening to Lin Shengli's story, Mr. Nie fell into deep thought again.

After a long time, Mr. Nie looked at Dean Qian and Team Leader Wang and asked, "What are your opinions?"

Dean Qian and Team Leader Wang looked at each other and said in unison: "We agree with Comrade Lin Shengli. Now that we have the technical information provided by Comrade Lin Shengli, we can definitely take bigger steps. "

When Mr. Nie saw that the three people present, the main scientific researchers involved in the launch vehicle project, all said this, he immediately made the decision without any hesitation:

"Okay, since you all have this determination, let's break this hard nut together."

"Team Leader Wang, if you have any needs on the project, you can report directly to Dean Qian, and we will definitely give our full support." Lin Shengli was relieved when he saw Mr. Nie's decision.

After all, in order to reasonably present the information provided by the system, Lin Shengli racked his brains and came up with a lot of rhetoric.

If he had been busy for a long time and ended up with something backward, Lin Shengli would not be reconciled to anything.

After understanding the situation with Lin Shengli, Dean Qian and Mr. Nie did not stay with Team Leader Wang for long, and turned around and left Team Leader Wang's office.

Before leaving, Dean Qian told Lin Shengli and Team Leader Wang that there would be new instructions from above soon.

Let their project team be ready at any time.

In fact, this was mainly meant for Team Leader Wang. After all, Lin Shengli was a free agent and did not have to report to the project team every day.

Today's matter has been approved by Nie Lao. This time they re-establish the project of a new launch vehicle with a weight of more than [-] tons. There will definitely be no problem.

Therefore, after Lin Shengli returned to the steel rolling mill, in addition to some necessary work, he also started copying and organizing.

This time, it was a little more complicated than the last time, because Lin Shengli discovered that among the materials he copied, some of the technologies to be used had not been developed yet, and Lin Shengli was not alone in a short period of time. These technologies can be developed.

Therefore, Lin Shengli can only use the existing conditions to see whether he can use the replacement method or integrate existing resources to realize this part of the content.

Another week has passed, and all the additional personnel assigned to the project have been put in place.

Even for the sake of safety, many security personnel were added inside and outside the small building where their launch vehicle project team was located in the already well-protected research institute.

As the team leader of the project, Team Leader Wang divided the project personnel into groups according to the previous discussion with Lin Shengli.

The only difference is that in addition to focusing on the core part of the launch vehicle, that is, the research and development of the engine, Lin Shengli also serves as a consultant for this project, coordinating the work of various research and development groups with Team Leader Wang.

After all, the information everyone uses for reference was created by Lin Shengli, and he is the only one who is most familiar with and understands this project.

In the simplest terms, Lin Shengli has become the golden sixth person in the project team, moving wherever needed.

For this reason, Lin Shengli had to start the work of the steel rolling mill and the project team, either in the morning or in the afternoon.

After the tasks were assigned, each R&D team entered into intense work.

In the eyes of the security personnel responsible for vigilance, the lights in the offices of various research groups in the office building of the launch vehicle project seemed to have never been extinguished.

One can imagine what kind of working condition these researchers are in.

Although Lin Shengli doesn't seem to have to work overtime on the project team, in fact, the time he spends working in the space is no less than those who work overtime in real time.

Lin Shengli is so busy mainly during the development process of this engine, even though there are detailed information and drawings provided by the system.

However, this toy is, after all, a product that represents the crystallization of high-tech technology. It does not mean that if you have the drawings, you will definitely be able to build it. It is not like building blocks based on the drawings.

However, the hard work will eventually pay off.

Not long after, the first prototype of a rocket engine for testing was produced.

This engine is the liquid rocket engine used in the first and second stages of this launch vehicle project.

After the engine has passed the test run and meets all the design indicators and parameters, a meeting will be held to start developing the solid rocket motor for the third stage.

(Long March 02 is a three-stage rocket. The first and second stages of the rocket use the two-stage improved Dongfeng-[-] medium-range ballistic missile, and the third stage uses the newly put into production GF-[-] solid rocket motor.)
This rocket engine uses improved liquid rocket engine technology provided by Lin Shengli. It consists of a thrust chamber, propellant supply system, and engine control system.

In terms of fuel, the most common liquid oxygen is used as the oxidant, while liquid hydrogen is used as the combustion agent.

The propellant supply system adopts a pump pressure system, using a hydraulic pump to transport fuel.

Subsequently, the prototype was sent to the launch test base in Gansu Province.

This day is the day when this engine undergoes its first test run and ignition as planned.

According to the original agreement with Lin Shengli, under normal circumstances, there is no need for Lin Shengli to come to Gan Province.

Although it was agreed like this, as the leader of the engine project team, Lin Shengli originally wanted to come and personally participate in the test ignition of this engine this time.

Unfortunately, the superiors have another task that conflicts with today's test drive.

However, after all, it is just an experimental test ignition. I believe everyone will do a good job in this test even if Lin Shengli is present or not.

When Lin Shengli is done with his work, he will come over and take a look as soon as possible. (End of chapter)
